00:01So today we'll be talking about designing an enterprise GIS security strategy.

00:06We'll have a brief introduction, find out a little bit about you guys, too, myself...

00:11...talk about Esri security strategy we're working on...

00:15...various deployment patterns we've been working on for the last couple of years...

00:19jumping into various IT security trends out there...

00:23...and then talking about mechanisms that you can deploy across our various enterprise products.

00:29Then drilling into more product-specific options, be it for ArcGIS Server, desktop solutions...

00:35...mobile solutions, and cloud computing.

00:38So that last one, cloud computing, I, I've had to spend a good amount of time over the last couple of months ramping up in that area.

00:45That's been a, quite an adventure. So, and then the recap and summary.

00:52So part of this session is also to get feedback from our customers, too, what key things are of interest and of concern to you.

01:00So that will be going on today too. So myself, I'm an enterprise architect within Esri's Professional Services Division.

01:08I'm also a FISMA certified and accred...accreditation application security officer; the federal agencies refer to that as an ASO...

01:17...application security officer, A-S-O, hey!

01:21When you think of security, what do you think of? Okay, there we go!

01:25So a certified information system security professional, and that's enough about me.

01:31So the question I have for you guys...this is a simple one... Are you happy with your current security?

01:37If you are, please raise your hand.

01:43Hey, I got one hand, I'm impr...oh, two, okay. Okay, so why do I ask this question?

01:51So, in 2009, Department of Energy National Labs put together a nice little list of security maxims...

01:57...so...sayings, adages, and so forth.

02:00So they're true about 80 to 90 percent of the time; I think you'll like this one.

02:05The "So we're in agreement" maxim, they called it.

02:10So if you're happy with your security, so are the bad guys. So...

02:15...so now a good point in your defense is that, hey, that 80 percent...

02:20...an 80 to 90 percent means that 10 to 20 percent of the two of you actually do have good security.

02:30So, we'll move on here.

02:32So, what does a secure GIS mean to our audience here in this room?

02:38Is it simply a matter of, okay, I noticed that somebody said I have clear text passwords, so I needed to turn on HTTPS...

02:47...or utilize this thing called SSL, put that in place, I'm good; there's this encryption thing going on.

02:53Or is it as simple as, I go to ArcGIS Server and I push a button to turn on this thing that actually does say, Turn on security...yes.

03:02Does that take care of the security for your enterprise?

03:06This session's more about not just particular implementation options and how to do those options but more about...

03:13...the options available across your enterprise and how our products fit into that.

03:17So integration with your various directory services, be it LDAP or a Microsoft Active Directory structure...

03:24...how we fit in with various standards, certifications, and regulations out there.

03:30So, FDCC...this is something we've started doing over the last couple of years...

03:34Federal Desktop Certified Configuration.

03:37All federal groups have to lock down their solutions to a particular hardened configuration for desktops.

03:44And products have to fit into that. So we've begun a self-certification process aligning with that.

03:50FISMA is federal groups for not just desktop but information system security in general.

03:57The various user interfaces out there...so we have quite a few now, or APIs, so we have...the ADF.

04:04You have Silverlight, Adobe, Flex, JavaScript, and various rich clients.

04:09So why would this have an effect? So let's take Adobe Flex.

04:13So what is the most...a common...attack surface, on a lot of Web applications right now?

04:20It actually is through that Flash-based plug-in on browsers. So it's something to be aware of...

04:26...that that can affect your enterprise implementation...and how you can go about updating those in an effective ma[nn]er.

04:34So there's also application versus security products. What do I mean by this?

04:38So this is how much security functionality Esri offers out of the box with our token service...

04:45...versus when you need to start looking at various third-party solutions on top of our products.

04:52So the key here is don't focus on trying to implement just a single security silver bullet.

04:59As far as our security strategy, so there's a couple reinforcing trends to our security strategy.

05:05One is about our products.

05:07So previously we've moved from discrete products, operating individually, to more of a uniform enterprise solution.

05:15Along with that, our security models changed a little bit in that we really didn't have much in the way of a security model...

05:21...with our early-on products. We relied on our customers to implement third-party mechanisms on top of ours.

05:28Now we do have some embedded security functionality.

05:31And I'll even talk about some new functionality that may be getting integrated with our product over the next year or two.

05:39So IT trends...so, moving from isolated systems to more integrated enterprise solutions...

05:45...where you have discretionary access amongst them.

05:50Then for our...as far as the actual components of the security strategy, we have secure GIS products...

05:55 ...which, where we incorporate security industry best practices that are trusted...

05:59that provide trusted geospatial services across the globe...

06:03...that meet the needs of individual users and entire organizations.

06:08So we also provide some solution guidance via...Resource Center is one component.

06:15It's a Web site we put together over the last year and a half or so, and I'm trying to pull it up here live...there we go.

06:23And so in the Resource Center...was...the overall Resource Center was updated at the...

06:29...in this list here, you have enterprise GIS. So it's sort of tucked away.

06:34But it has quite a bit of content in it once you get into it.

06:38So enterprise GIS area is about architecture security and performance.

06:42One thing we added over the last month is that your information and links for these various pages are all version, now, specific.

06:51So I switched to 9.3...my now helpful resources are about 9.3.

06:56All of the pages I drill into here are about 9.3 as opposed to 10.

07:01So basically, you split down two different paths, but the sites look very similar.

07:07So in this site, we have strategy options, which we'll be talking about today...

07:14...security mechanisms deployed across the enterprise...

07:17...and application-specific functions. So you can drill down into...well, I'm interested in...

07:23...what are some of my authorization options across the enterprise with Esri products?

07:28And then I see a link in here for, you know..

07:30...hey, I would like to see a sample of this idea of hiding some objects within the application.

07:37Now notice it jumped into 9.3 help, so in the 10.0 site, it'll jump directly into the 10 site.

07:46We also will be making slightly different...we'll be updating the architecture representations specifically for 10 versus 9.3...

07:55...so that there's not as much of this question of, well, so I went to the Resource Center, you know...

08:00...the Enterprise GIS Resource Center...I wasn't quite sure it was applicab...applicable to me; you know, I have 9.3...

08:07...but there's this stuff out there...was it 10? Which is it?

08:10So that's why we went with the version strategy.

08:14So another key area is the Implementation Gallery. So this is where we provide helpful documents, test results for performance testing...

08:25...some security hardening guidance of systems.

08:29And here specifically is a security guide on .NET Active Directory membership providers.

08:36So it's a...called a custom provider, and we'll talk a little bit about that more soon.

08:44So as far as our security strategy, it's based on a couple of key core security principles.

08:50So you have the CIA security triad, consisting of confidentiality, integrity, and availability.

08:56Now, one thing that 's very common for GIS users is they go, Well, you know what, my end result is primarily public data...

09:04...so why is it that my security guy is bashing me over the head to lock things all down on my system...

09:10...when the end result is I want to give this information to the public?

09:14Well so, that one of giving information to the public; that's addressing...we're talking about confidentiality.

09:20But integrity...so if somebody was to take your public Web site...let's say it's parcel information, manipulate a parcel...

09:29...because now there's Web editing...and maybe adjust a parcel to their advantage, and then they present that to another party...

09:37...using your Web site, that you said, Hey, I'm serving public information, somebody manipulated it.

09:43You have an integrity information issue.

09:46There's also availability...its relationship to security, you have these denial-of-service attacks that are not that uncommon, actually...

09:54...where somebody can come down...come out, just hit your site real hard, and take it out at the knees.

09:59So what if your site was providing emergency operations information to the public?

10:05It didn't matter if, you know, as far as somebody hacking; that you weren't too concerned about that.

10:11But you were concerned about making sure those people have that information 24/7.

10:17So defense in depth. This is, ideally, you have a whole bunch of layers of security across your organization, at different levels.

10:25So this representation here, I have data and assets at the core protected by physical controls...

10:31...be it how you lock down your data center, your doors, and...is your server actually locked up in a rack...versus policy controls of....

10:41...how often you change your passwords and other components like that.

10:47Our primary focus here today will be about the technical controls or mechanisms that you can deploy across the enterprise...

10:54...because there's more of a direct correlation with technical controls and our software.

11:00So there's authentication, authorization, filtering mechanisms, encryption, and logging.

11:05We'll talk about all those more soon.

11:11So our security implementation patterns are based on best practice guidance that we've accumulated over time.

11:17They'll leverage also the National Institute of Standards and Technology guidelines...

11:22...for a low-, medium-, and high-risk type of environment.

11:25We also...so the key thing of this is, the first thing you need to do is understand where you fit in this.

11:32So, am I a basic or standard type of need or advanced type of need? And how do I go about doing that?

11:38So I'll talk about that relatively quickly.

11:41So...choosing the right pattern...you can go the formal approach; all of our federal customers have to do it.

11:47They don't really have any choice.

11:50So there's this publication out there...860.

11:53Some actual large corporations follow this same type of guidance.

11:57There's also, we've also created a more informal process to give you a better feel...

12:03...rule-of-thumb type of direction, for going the right path.

12:07So for a basic security type of environment risk...there's no sensitive data; it's public information.

12:14This is where you can start, you can have, pretty much, your architectural tiers combined into one...

12:18...be it your Web, app, data, information.

12:21In a standard environment, you need to start breaking out these components from each other, because there's a...

12:27...where there's more moderate consequences for data loss or integrity.

12:31And there's also a potential need for federated services...

12:34...so this is where you have potential more integration with other businesses...

12:38...and communicating with those other businesses in a secure fashion.

12:42And last but not least is advanced security needs. I have sensitive datasets.

12:46All the components are now needing to be redundant to ensure that availability component.

12:51It's also where you need to think about utilizing more and more third-party enterprise security components...

12:56...on top of our basic security functions.

13:01So a basic security environment. What is it? What are some attributes of it?

13:05Well, in this case, I have a Web application with both anonymous users and authenticated users.

13:12I'm also utilizing some ArcGIS Online basemaps.

13:16This is a public cloud reference down at the bottom; it could be Google's; it could be Microsoft just as well.

13:24So you're use...but one thing to note also is the API, by default with ArcGIS Server, is coming from ArcGIS Online.

13:32So it's just a dependency you have that you need to be aware of.

13:36So you can secure the services with a token service that's adequate for this type of model.

13:41And you want to separate your internal systems from Internet access with a DMZ, very common.

13:48And then a re...reverse proxy, to avoid DCOM calls across the firewalls.

13:55So I haven't made nice little diagrams yet for the standard and advanced environments.

14:00I have more of a list of common attributes.

14:04It's quite an adventure to come up with a diagram for these environments and not get critiqued to death.

14:10So I figure I'd start with the attributes and then work up to the diagram.

14:14So, for the standard environment, you also want to just think about a component called a Web application firewall...

14:21...in addition to your reverse proxy, or in place of a reverse proxy. I'll talk about those more soon.

14:28You also want to utilize dynamic based tokens.

14:30You don't want to use these static things, just make them long-lived for, you know...

14:34...one year and hope that nobody compromises that over time.

14:38You want to separate the tiers out, which we've talked about a little bit before, the Web database.

14:43And even management systems, especially even on the...the supporting network infrastructure.

14:48So there's this idea of a flat network where all my systems are...have access to each other, or you start segmenting it with VLANs.

14:57Ideally, you start doing that in the standard environment.

15:01There's also multifactor authentication utilized for external users of the solution.

15:06And you want to separate management traffic connections and have redundant components, local copies...

15:12...for your datasets for high availability.

15:16This is where you want to also start thinking about those APIs I mentioned that came from ArcGIS Online [dot]...by default...

15:22...or ArcGIS.com, by default.

15:26You want to start deploying those locally, on your local server.

15:30Do you have an SLA with ArcGIS Online, or an external cloud provider...

15:35...to ensure that those are going to really remain available for you?

15:39So that's the reason you want to have those locally in this type of environment, to ensure that you're meeting your SLA requirements internally.

15:47So you also want to ideally utilize what are called intrusion detection and prevention systems...

15:52...lock down various ports and protocols and services.

15:55There's a nice hardening...system hardening guidance white paper that we've put together.

16:01And we'll be updating that later on this year for 10 and Windows 2008.

16:06You also want to standardize your system images, be it virtual images, AMIs from Amazon, or within your own enter...

16:15...en...organization or enterprise, be it with Microsoft solutions.

16:21So you also might want to utilize host-based firewalls on your individual servers.

16:26And last but not least, in this type of environment, browser plug-ins start kicking in, so...

16:30...be it for Silverlight or Flex, and so forth.

16:36For the advanced environment, you have minimal reliance on external data and systems.

16:44So starting to remove those external dependencies as much as possible.

16:48You want to separate your datasets, be it public employees, a...a subset of those employees, and so forth.

16:56You might want to start getting into labeling your datasets, as it's called.

17:01There's also some options called transparent data encryption that can be utilized against a database system.

17:07And utilizing third-party security mechanisms to secure your Web services traffic.

17:13So there's quite a few of those.

17:16There's public key infrastructure certificates for client-side validation.

17:21When you have local users accessing the solution, you ideally would be using what's called multifactor authentication.

17:28Something you are, something you have, something you remember...there's multiple factors for accessing a system.

17:36And so remote users access via hardware token multifactor authentication.

17:45And you have network connections that are redundant with ideally .NET IPSec traffic between those servers.

17:52Utilize SSL transport layer security between your clients and servers, for both Web and rich clients, so desktop solutions.

18:01And then there's also this idea of network access control.

18:04So that's a...the idea is basically, hey, if I had somebody with a laptop that comes into my organization, they plug in the connection...

18:13...the systems check to see if your laptop even has the right security patches on it before it can become a part of your network.

18:21So it's a[n] interesting concept and used by some of our customers.

18:26So jumping into some security trends here.

18:30So I did a quick Google trends here in the lower left...of the term cyber security, and how it's changed over time.

18:38So starting off in the '90s...it started off, brief discussion...but for some reason, it peaked up in 2003, 2004.

18:47You had Code Red, you had Melissa...do you remember, anybody get that "I love you" e-mail from good ol' Melissa?

18:55So there were some interesting ones out there. This is a time when there was a discovery process that, hey, we're getting on the Internet...

19:03...we're having a whole bunch of you people use things...boy, we really need to lock things down...Microsoft.

19:08This is Microsoft's discovery period, ha!

19:12But as you can see...2005, 2006, 2007...there was sort of like this tapering off interest...and...

19:21...but all of a sudden, in 2008, 2009, there's increased attention, and we'll talk a little bit about that soon.

19:28So this guy is an interesting guy, one of the early hackers. His code name, we'll call him Captain Crunch...because what did he do?

19:39He basically took the plastic whistle out of a Captain Crunch cereal box, blew it into his phone...

19:47...and discovered that he could get free access to AT&T's whole network.

19:51So, one of the first early hacker attempts by an individual.

19:57So where are we at, getting closer today? What are the types of attacks?

20:02Well, we have people trying to get the attention of the president, Hey, candidates, you know what?

20:08I'm going to hack your Web sites. Both Obama's and McCain's Web sites were taken down.

20:14It's a good way to get their attention. Then you had multinational network sort of discovery.

20:21So there's these things called GhostNet out there, which you can research on your own, but 13-plus-hundred systems being compromised...

20:30...all interoperating as a network of attacks. What about even more recently, this year?

20:38Maybe some of you have heard about Google and them being compromised, or admitting to being compromised, at the beginning of this year...

20:46...along with about 30+ other large corporations. They were after the company’s source code, which was quite interesting...

20:55...because we still don't even know for sure what they were planning to do once they collected that source code.

21:03So what has this also driven? This has driven active legislation. So our Senate, writing to the president, just on July 1 here...

21:14...saying, We have some serious issues with cyber security for our critical infrastructure of the United States.

21:23So what are some of the issues? So CSI, Computer Security Institute, does a survey every year.

21:30There are some big jumps right now in password sniffing. Actually, it's easier to sniff than it used to be sometimes, for passwords, and so forth.

21:40There's nice, little browser plug-ins, be it Fiddler or other ones where you can see all sorts of Web traffic.

21:46So we've made it user...easier for users to consume that information.

21:51There's a lot of financial fraud going on, and there's malware infection increasing significantly.

21:58So what are people doing to try to address these types of issues?

22:03Well, some of the higher-priority items were log management, so collecting information that's distributed widely over an enterprise...

22:12...and then being able to report that in [an] effective dashboard to executive and also management because...

22:20...what's happened is that systems have become so complex...

22:22...and so many diversified systems trying to keep track of each system individually...

22:29...is not a manageable solution.

22:33So now I'll jump into some security mechanisms that can be deployed across the enterprise with our products.

22:40So you have authentication, so identifying, hey, is this Bob or Sally that's going to have access to the system?

22:49Is this Bob or Sally? is really the question. Then for who has access...

22:55...Can Bob access this map here but not the other map over there?

22:59That's called authorization. Then we have a variety of filtering mechanisms.

23:05So let's say Bob gets into your system...

23:07...but now he makes a malicious attack across your wire towards your, let's say, ArcGIS Server.

23:14What's going to block that? So ideally, having some filtering mechanisms for that.

23:19Then you have encryption mechanisms to protect that information going across a line or at rest on a hard drive.

23:27And then you have logging and auditing for what's called nonrepudiation.

23:34For authentication...So ArcGIS Server has three basic schemes.

23:39For Web traffic, it has two items; you have Web services and Web applications; those are both circled at the top.

23:47Then you have this internal communication that's based over DCOM.

23:51So each of these have different mechanisms to approach. I don't expect you to read this whole chart here in detail right now.

24:00The key thing is...is that you have different options for authentication, a ton.

24:07So, if somebody just calls me up and says, "Hey, Mike, can you just quickly tell me...

24:11...the authentication option I should be using for my deployment?"

24:15Well, there's quite a few, so by default, for Web services and applications, no security is used with ArcGIS Server.

24:22Now you could, let's take IIS, turn on either Basic, Digest, or Windows Integrated the...authentication...

24:29...and that results in a little browser pop-up dialog for end users.

24:34Or on the JavaWorld, you could use containers, then if you have more advanced security con...

24:39...needs, you could implement a public key infrastructure...

24:42...with client-side certificates and even smart cards.

24:48Now, the red part here is for specifically only Web applications, so you have .NET form based and Java - - ArcGIS managed.

24:56Then you have a Web-service-only interface, so it's the ArcGIS token method.

25:02So why do we have that? It's something to protect across platforms, be it .NET or Java...

25:08...be it the SOAP APIs or REST APIs, for providing a common mechanism.

25:15There's not really a standard that goes across those by default in the IT world at this time.

25:21And last but not least is that local authentication I mentioned...

25:24...with DCOM, which ties in with the Windows Integrated authentication many times...

25:29...where you have two groups in the operating system...agsusers, agsadmin...and you really have three levels of access...

25:37...none, you're a user, or you're an administrator for those local connections.

25:42So it's that Web security that gives you that more fine control of role-based access control.

25:51So where do you store these various users and roles, also called a principal store?

25:56Well Java has a set of options; .NET has a set of options.

26:00On the Java side, we start off by de...you def...with...by default with an Apache Derby database.

26:06You can point it to an Oracle database or SQL, other database vendors; it's up to you.

26:11There's LDAP infrastructure if you want to utilize that, or even Microsoft Active Directory.

26:17For .NET security store, by default you have the Windows users and groups; that one creates a little bit of confusion.

26:24They're like, okay, so is that Active Directory, or is that...is that just my local machine or something else?

26:31Windows users and groups is a choice for you to use just the loc...a particular machine's users and groups it's aware of or...

26:40...a domain's set of users and groups.

26:45You can also utilize Microsoft SQL Express or the SQL Enterprise Edition out of the box...

26:52...or you can implement a custom provider.

26:54So I pointed to that help document in the Implementation Gallery or that white paper in the Implementation Gallery.

27:02That was for stepping you through how to implement a custom provider.

27:09Authorization. So we provide role-based access control with our COTS product to the service level.

27:15Some of our users want more fine-grained sec...security control than that.

27:21So Arc...you use ArcGIS Manager to assign various rights to these groups, what they have access to.

27:27And the services are grouped in folders that have inheritance with them.

27:32So you can utilize third-party products to get more granular...

27:37...so relational databases you can implement role-level or feature-class-level security.

27:43However, you need to be aware of, if you're doing multiversioned instances...

27:47...it can significantly degrade the performance of your solution.

27:51You also have the capability of utilizing SDE views instead of that.

27:57So you can also limit the...what's displayed in the user interface.

28:02So for rich clients, utilize ArcObjects to do that.

28:05For your Web applications, I actually pointed at that common security code snippet.

28:11And there's also a nice little tool out there from Microsoft called AzMan; it's basically a[n] authorization management tool.

28:23So filtering mechanisms. These are primarily third-party options to utilize with our products.

28:28Firewalls...protecting ports and protocols...access to those.

28:34A reverse proxy...common implementation option with our products.

28:38Microsoft now, with 2008, provides code to be able to implement a reverse proxy with IIS.

28:46Many times, because customers were trying to avoid the cost and overhead of a[n] ISIS Server...

28:51...they would implement an Apache solution, instead, on top of it.

28:55You don't need to do that now for your IT team.

28:59Web application firewalls. So ModSecurity can significantly reduce attack surface on top of this reverse proxy.

29:07So ModSecurity is an open source implementation option of a Web application firewall.

29:13There's antivirus software that you should incorporate on your system, IDS, IPS intrusion protection solutions.

29:20And you also have this option of limiting acc...applications' access to the geodatabase.

29:25So you can say arcmap.exe is the only one, only executable...

29:30...that's allowed to actually access my database, so independent of the users.

29:34It's another type of filtering, and that's done by the database tier itself, be it SQL Server or Oracle.

29:44So a firewall-friendly scenario of implementing our products.

29:49So I have a couple acronyms here that are not explained, of course, just to keep you on your toes.

29:54So, in the quest for obfuscation, right?

29:58So reverse proxy obfuscates internal systems.

30:01So obfuscation is an interesting one because a lot of security guys say that's not security.

30:08So what's the purpose of our proxy here? Reverse proxy.

30:13Well, it can help security...some; it's just the amount of degree that it can help, depending on your configuration...

30:20...and how much you supplement it with something like a Web application firewall function.

30:25So the communication between the proxy and the server, right here, can be on any port that you choose.

30:33And then, in this case, we implemented a file geodatabase in the...a DMZ.

30:38Why did we do this?

30:40Well so, over here, we have our production internal operations, a relational database that's versioned...let's go back...let's see...

30:49...come on, one more, there we go.

30:51And then we take just the default version, send that over to the file geodatabase replicated over there.

31:00So what we've done is we've segmented datasets that we have, our data-sensitive ones internally...

31:06...our ones we want out to the public dataset...

31:09...public users out in that DMZ, hey, if they compromise that whole file geodatabase, take that whole thing, so be it.

31:16But they haven't gone anywhere near your internal operations.

31:20This is also good for performance, because you can stack a whole bunch of those file geodatabases on each of your...

31:27...each server you have...you can have another file geodatabase.

31:30So you have the read/write capability of a whole new blade for each one of those instances without incurring any special licensing costs...

31:41...for a relational database system.

31:45So for encryption, a lot of third-party options out there too.

31:49So for the network, we have a, for VPNs, it's common to use...for external users, it's common to use IPSec.

31:58Some organizations use IPSec for protecting server-to server configuration...communication.

32:06And then, there's also file-based encryption...

32:09...so you can utilize components like, that's called BitLocker from Microsoft or this EFS, encryption file system.

32:18There's also the capability to use geospatially enabled PDFs combined with certificates.

32:23So this is utilizing an interesting concept. So I take ArcGIS Server, create a geospatial PDF.

32:30I can then take that PDF and sign it to say I only allow particular users to be able to open this document...

32:38...and they have to have a certificate...

32:40...or smart card with a certificate, to be able to view it or do particular functions with it.

32:46So, and that relies on a public key infrastructure. But so you basically get a PDF lockup information and then hand it out there.

32:54There's also hardware-based solutions...

32:56...so you can purchase now hard drives that encrypt all information written to them on the fly.

33:05And last but not least, here is relational database management system encryption, so a transparent data encryption, I've talked a little bit about.

33:12One solution for those remote field operations...people on the desk...out in...doing operations out...complex field...

33:20...operations out in the field that need to be locked down.

33:22You give them SQL Express, implement transparent data encryption, if their system...

33:28...somebody runs away with the whole hard drive and system, it's encrypted.

33:36Enterprise-wide security mechanisms...continuing to logging and auditing, so for nonrepudiation many times, so...

33:44...with our products, we have geodatabase history that can be utilized for tracking changes.

33:49We have the ArcGIS Workflow Manager, previously called JTX, that track...can track feature-based activities.

33:56And then in 10, we added some new user...a new user tag to track various user requests on the systems.

34:04So that tag is automatically turned on as soon as you turn on the ArcGIS Server security model now.

34:11And then, of course, you have a variety of logs out there for Web servers, relational databases, operating systems, and firewalls.

34:19Okay. So that's plenty of high-level stuff.

34:23Let's step a little bit into what options are for particular products and solutions.

34:29So ArcGIS Server secure m...Server security. So as opposed to going through each individual option of ArcGIS Server security model...

34:38...I'm going to ask questions that some of our customers are...seem to be not clear on what's going on...

34:45...or what things are configured by default, let's say.

34:49So who...who here believes communication with ArcGIS Server's Web services are secure by default?

34:59Oh, good, so we're communicating well. So, no, it's not.

35:03Communication via ArcGIS Server and all clients are clear text by default.

35:07Secure Web communication, you can ideally utilize an SSL cert. to secure that.

35:13For those DCOM local communications, you can use IPSec tunnels between those systems...another interesting one.

35:22So I have a large Internet provider solution, and I'm exposing Web services out there with ArcGIS Server.

35:33Do I need to have a reverse proxy in that implementation?

35:37Who says...so is a reverse proxy required, yes or no?

35:43If you believe a reverse proxy is required, please raise your hand.

35:49Okay, we have a couple people. So the actual answer is no, it's not required, and not even for security.

35:58So some customers implement a reverse proxy to eliminate DCOM traffic across firewalls within their internal operations.

36:06So a particular security group might make it a requirement, but it's not a requirement to implement a secure solution.

36:16So, when used with a Web application firewall, that's when you really start improving the security function of a reverse proxy.

36:27So is there security hardening guidance from Esri?

36:30So I need to lock down my operations; how do I do it?

36:33Or I keep on configuring ArcGIS Server, and my IT group says I have to do these particular things...

36:39...I do it, and it falls over. Is there some basic guidance?

36:42The answer is yes.

36:44Go ahead and check out the Enterprise Resource Center Implementation Gallery.

36:48We'll be updating this security guidance before the end of 2010 with the version 10 and Windows 2008.

36:56Let me know if you have other particular implementations you need guidance on.

37:04Another interesting one.

37:05Should I assign the everyone group in...to the root in ArcGIS Manager? What does that mean?

37:12Okay, well, I set up ArcGIS Server; by default, it doesn't have this security function turned on.

37:19So I go ahead and turn on this security function, which some of you probably have done, and all of a sudden, nobody can access my system.

37:27So what does somebody do in response?

37:29They take the everyone group and put it into the root.

37:32Now, what have you done?

37:34You've just all of a sudden converted your system back to everyone has access to your system again for everything, by...by default.

37:41Now, some people want that model, because it does make it easier to use.

37:46So this is...I didn't even have you raise your hand on that one because it really depends on what your needs are, right?

37:53A lot of our customers have a basic security need; they don't have this medium or high security need.

37:58So ease of use is extremely important for some of our customers.

38:03So this basic security model...it's an okay implementation option, but it's not really recommended for standard or advanced.

38:10The common security practice is deny by default in higher-risk environments.

38:18So can I provide security more granular than the service level, yes or no?

38:23If you believe yes, raise your hand.

38:28Okay, so we've got half the building, and maybe the other half is asleep; I don't know... can't judge that easy enough.

38:35Yes, you can; right now, you have these SDE views or third-party software relational database components, and so forth, to help supplement that.

38:45We also have this other future option we're working on, this integrated security model...

38:49...being able to pass user context from Web server to application server to database server tiers.

38:56So briefly, what is this new integrated security model?

39:00As I mentioned, the user context passes through; what's the big deal?

39:05So it allows you this more fine-grained access control, role-level security; it also can provide you a single interface for HTTP and DCOM connections.

39:15It also can improve your capabilities for nonrepudiation throughout your environment.

39:21Current release status of this is we're collecting more customer use case information.

39:26Validation of this will potentially lead to production support...

39:30...but we have some outstanding concerns of the performance, security, and usefulness of this solution.

39:36That's why we're still in this mode of working with the customers to refine this.

39:41What are some of the main scenarios it addresses?

39:44As I mentioned, centralized security management...

39:47...so both local DCOM and Internet connections managed from the ArcGIS Server management interface...

39:53...utilizing Windows integrated security.

39:58So right now, you manage those two levels of security, your local connections and your HTTP connections...

40:05...completely independently from each other.

40:08But this model could change it.

40:11So you also flow the Web user identity to your database via what's called a proxy user.

40:16So this is a relatively newer technology in database systems...

40:20...that you don't establish a separate session to the database for every user accessing the system.

40:27So you sort of can lump user accounts through, but you add a sort of a...like a WHERE clause onto it saying...

40:33..."where the user is John,"...

40:34...or "where the user is Bob," using that same connection.

40:38So it allows you the capability to make a lot more scalable type of solution.

40:43So this will allow for logging functions...

40:46...nonrepudiation across all the architectural tiers in high-security types of environments, those advanced security needs.

40:53It also provides that role-level security function we talked about.

40:57You also might want to implement a custom server object extension...so...to make use of, hey, it...

41:03...now that I know a particular user is using this particular function with ArcGIS Server...

41:09...I could potentially implement feature-level security doing that.

41:16So what does integrated security look like, providing role-level...and role-level security?

41:22So in this case, the user is logged in as administrator; I see both red and green lines.

41:28When I log in as just plain old Mr. other user, just Joe user, I...those red lines magically disappear.

41:37So it's a single Web service that the database has now...because it knows of particular users...

41:44...it knows to not be able to provide particular information back to the end user.

41:49One of the issues here, of course, is that, in this case, for a roads network, lack of information implies...

41:55...you know, the mind can sort of fill in the gaps in some of these road networks...

41:59...that something interesting is occurring along those road networks that I'm not allowed to see.

42:05So desktop security. This client typically has the most access to sensitive datasets out there.

42:14Now, the reason that's historically not been too much of an issue is it's in a more secure environment.

42:20It's not exposed out there on the Internet for everyone to access anything.

42:26So you have a variety of system connections.

42:28You have direct connect to the relational database management system via standard SQL calls...

42:34...you have application connect to SDE, and you have HTTP service request, geodata service, and so forth.

42:40You also have integration with the token service and Windows native authentication.

42:46You also have ArcObjects development options [available] to you...

42:49...and you can record user-initiated transactions, fine-grained access control...

42:54...such as edit, copy, cut, paste, and so forth.

42:59So the one that's sort of interesting here is geospatial cloud computing, or hopefully the other ones were interesting too...

43:05...depends on your mind-set.

43:07So, question for to...today, a real nice, easy one...so who here thinks cloud computing is safe?

43:16Raise the hands...so I got...I got two hands...one and a half hands.

43:23Nobody else thinks cloud computing's safe?

43:26It really might not be that bad. So, the answer...it depends.

43:32You like that? And we'll just leave it at that?

43:36What does it depend on? So cloud computing actually has some interesting security benefits...

43:42...and I got some of my information also from some research that...that the government's been working on too.

43:50So virtualization and automation...automation of systems... What does that result in?

43:56Well, I'm able to take standard images and stamp those out on a whole bunch of systems...

44:00...I don't have to rebuild each system from scratch.

44:04So for security, I can make a whole bunch of systems identical quickly, easily.

44:11You also have broad network access.

44:13This was an interesting one that came up that said, hey, now that I can access my same information here as I can in my office...

44:22...I don't necessarily need to carry around a USB key to transfer datasets...

44:26...those nasty USB keys, carrying viruses and everything.

44:31So there's also this idea of segmenting datasets...using the public cloud to your advantage.

44:37But you say, Well, public cloud, what should I keep out there?

44:40Well, how about public datasets?

44:42Keep those in the cloud, and then your internal operations, you keep your sensitive datasets.

44:48So it's not like an all-or-none type of thing. Talk more about that ____________ soon.

44:53So there's also potential economies of scale.

44:56So you have lower-cost backups...it's lower cost to back up your datasets out there because of their infrastructure.

45:02And then you have various self-service technologies available to apply security controls on demand...

45:07...be it a...a...their simple firewall control changes, or so forth.

45:13So what are some of the risks of implementing into a cloud?

45:18So first is vendor-practice dependence. It's now dependent on what the vendor, the cloud vendor, is doing.

45:26So there's potential substandard security controls out there resulting in vulnerabilities.

45:32There's also a little bit of the loss of governance and control.

45:36Sometimes, why, I don't know where my dataset's going to be.

45:39I specifically don't know what machine it's going to be on; sometimes I might not even know what country it's going to be in.

45:47Vendor lock-in...so this is an interesting one too...so we have...

45:51What happens with your datasets once your services are terminated?

45:54Some cloud providers write up their requirements pretty clear; other ones, it's a little bit more agile, we'll call it.

46:03So be aware.

46:07There's a lack of tools, procedures, and standards to ensure portability...

46:10...so I cannot easily take my image that I make for one cloud provider...

46:16...and roll it out into another one.

46:19So if I create an AMI with Amazon, I can't roll that out into any other cloud provider other than Amazon.

46:27Now there's advantages for Amazon too; I'm not bashing them, but just an example.

46:32And you can also be hostage to the vendor cost increases.

46:35This is a concern of the governments, too, saying, well, okay, so now...

46:39...you're saying you're a vendor; we don't have to hire as many IT guys...

46:43...you're going to do a lot of those functions for us...we get rid of these IT guys.

46:47Now you decide to dramatically raise your rates. I can't pull that back away to my IT group because they're nonexistent.

46:55They don't know how to do this stuff anymore.

46:58So anyways, it's an interesting phenomenon, and it's just that loss-of-control concern.

47:04There's also the sharing of computing resources, also called multitenancy.

47:09This is where you can have intentional, or unintentional, gaining access to other users' data out there.

47:16There's also unclear responsibilities during security incidences right now.

47:21So who's in charge of the forensics process?

47:24Are you, as a customer of a cloud solution, allowed to follow that forensics process or help facilitate that?

47:29Will you have access to anything to help facilitate that?

47:34There's also increased data being transmitted across a wire.

47:38That same thing I said that was an asset for that USB scenario is also potentially a risk.

47:44Because now you're sending more data, you've now increased your disclosure risk.

47:51And of course, there's the...the threat exposure varies upon what's called a deployment model; I'll talk about those briefly.

47:59But you have a private cloud, which has relatively lower risk of...of threat exposure.

48:05You have community, and then the highest threat exposure is in the public cloud.

48:09Those are all relative.

48:13So these...what about the service models, and how do they affect an organization?

48:19So I have Infrastructure as a Service; I didn't put the expand out, these acronyms to the right because...

48:29...I really translated it to what it means to a security guy, or a person trying to implement a solution.

48:36Infrastructure as a Service...what does it mean?

48:39I get administrative access of [to] the operating system and all the software that's deployed on that VM.

48:44So now I'm managing that; I'm responsible for the security of that operating system...

48:49...and the configuration of it, and every single software component on it.

48:53So ArcGIS Server for [on] Amazon EC2 provides you an Am...

48:58...AMI, it provides you the operating system, the software, ready to roll...

49:04...but who's responsible now, as soon as you get that up and running...

49:07...for managing the security of it, locking it down, and so forth?

49:10It's the customer.

49:12So we also have customers implementing...

49:15...be it with Terremark, and we also have various private cloud implementation going...options...

49:19...on...customers implementing private clouds right now.

49:24For developers, they have this thing called Platform as a Service.

49:28So Esri, we provide up...these various Web mapping APIs out there...JavaScript, Flex, so forth.

49:34Microsoft has their Azure environment.

49:37Some of our customers have implemented ArcGIS [API for Microsoft] Silverlight applications in the Azure environment.

49:46And then, there's the end users...Software as a Service (SaaS).

49:50So this is where, basically, I don't want to administrate, I don't want to develop, I just want to use the software.

49:57ArcGIS.com is an example, the sharing environment, Business Analyst Online, and ArcGIS Explorer.

50:06So the cloud deployment options...talked a little bit about those a bit...little bit ago.

50:11So it's about location.

50:15So a public cloud implementation...Amazon hosts it; they're doing everything for you with the systems out there.

50:21Private cloud, you're going to do that in your internal corporate infrastructure.

50:26There's also hybrid and community, and all those, there's mishmash, but those are the two extreme.

50:31Somebody else completely does it, and the house and all the infrastructure are really, you are doing it...

50:36...yourself, and your internal operations.

50:39What is the primary driver between this public and private deployment? Security.

50:45So back in the...just well, last month, IDC did a survey of IT executives saying...

50:52...Okay, so is there a preference for using a private cloud versus a public cloud?

50:57So 55 percent said, Hey, a private cloud was more appealing than a public cloud.

51:03And 22 percent said, you know, Roughly a wash.

51:06So one interesting thing I got out of this is that it's not like a cloud implement...

51:12...a cloud implementations are going to be one particular path or direction for public or private.

51:17You're going to see a mix from within organizations.

51:23So one of the things I talked about earlier was assessing your particular security needs.

51:28Same thing needs to be done for cloud computing.

51:31For your data sensitivity, understanding, Is it pum...public domain information?

51:35Is it sensitive that I need to keep track of closely?

51:38Or is it classified?

51:40Identify my user types, be it public or internal users. And then categorize your solution accordingly.

51:46Same type of security pattern of basic, standard, advanced.

51:50Now most public cloud implementations are basic at this time.

51:54Think of the security model similar to social networking sites such as Facebook...

51:59...which hopefully you're aware of periodically gets hacked.

52:03Most...some people...well, so that's a funny one, right?

52:06So I gave an analogy of, you know, cloud computing...

52:11...public clouds being analogous to a social networking site like Facebook, and they said...

52:16...Wow, that's the best thing ever; I've never seen that or heard of any issues, and I'm like, okay, you know, just be aware.

52:24Most GIS users will have only basic security needs though. So, I mean, it's...

52:30...you can worry a lot about risk and, you know, solutions, but...

52:35...how...how much is it relative...how much are you concerned, with your organization, about those risks?

52:41So some interesting topics out there...I talked about data location.

52:45An interesting one that comes up for international organizations is the Patriot Act.

52:50They say, okay, so you're saying, hey, if I give my data into the Google's cloud...

52:55...Google can't promise me where that data live[s] or resides.

52:58If it happens to end up in a server in Kentucky that the government could technically, at any point in time...

53:07...say it's their data to read, the United States government.

53:10Gets the inte...international customers little bit concerned.

53:14Some cloud providers don't assure location.

53:17So Amazon currently provides a mechanism to say, yes, we'll keep your data at this particular location or a country.

53:26Google currently, from my latest understanding, does not do this, at least yet.

53:32Identity management is another tough area in cloud computing that's to be addressed.

53:39So there's a long-term vision formulating a national security strategy for trusted identities...

53:44...was just released at the end of last month, but this has got a long ways to go.

53:51And why is identity important?

53:53Well, if we look at the compromises of Google and other environments just in the last year...

54:00...we weren't able to identify who those people were that did the compromise to our solution...

54:06...due to a lack of identity management.

54:10So a shared responsibility model...this is something that's core to cloud computing.

54:15The cloud provider is not taking full responsibility for the solution gets...[getting] implemented.

54:20It's shared. The customer takes some; cloud provider takes another part.

54:25However, the details of who has responsibility for what is not very clear many times.

54:32So this makes it also very difficult for aligning with the regulatory compliance...quite questionable.

54:42So what's some best practice guidelines for implementing solutions in the cloud?

54:47Well, if your security model is beyond basic, then you need to start thinking about the same ideas of breaking up tiers...

54:54...such as shown in this diagram...Web app, database.

54:58You want to protect your da...information in transit across that wire, and you also want to protect information at rest.

55:05That's a key one for cloud computing and customers more concerned about how to do security, you know...

55:12...in decent format in cloud computing.

55:16So what you could do is encrypt your information at your site in your organization before sending it into the cloud.

55:24It remains encrypted out in the cloud until it's actually served out to the end user.

55:29So the cloud pro...provider doesn't have readily available access directly ever to that dataset.

55:36Credential management...I talked about the importance of that. You also might want to implement the built-in firewall...

55:43...operating system firewall capabilities.

55:45And there's also the ArcGIS Server application security model; it can layer on top of that.

55:51So ArcGIS Server on Amazon EC2. So the default deployment, what is it, out of the box?

55:58You get this AMI, which is a confi...configuration of ArcGIS Server, Windows 2008, and has a file geodatabase...

56:08...so all your tiers are really combined.

56:11Now we provide some scale out guidance in the help along with that, and you can look that up on the Web.

56:18But what about the supporting infrastructure behind this? How does... When I have that number of VMs starting to spin up...

56:24...so four, five, six VMs starting to spin up in that environment...

56:29...how do I ensure that those are all secured in a relatively effective fashion?

56:35Many people are setting up this RDP thing, remote...

56:37Okay. So you want to minimize your administrative attack surface across these virtual machines.

56:43So if you have a Windows box, users commonly ought... log in via what's called RDP, Remote Desktop Protocol.

56:51But you don't want to necessarily expose this on all your servers, because it's sort of, you know, the keys to the kingdom.

56:59 So what you can do instead is set up a management instance in front of all your servers...

57:04...and then your back-end servers can talk amongst themselves...

57:06...and you talk to the other servers through that single management instance.

57:12So what if you wanted to get into more advanced single sign-on integration in cloud computing with your operations right now.

57:19So Amazon has this virtual private cloud implementation of VPC where you create an IPSec tunnel between your internal app or...

57:28...enterprise and the cloud implementation.

57:31You really don't have to do much special to accomplish this...

57:35...because it just ties in with Windows integrated authentication across that tunnel.

57:41 Now what if you don't want to have that VPN tunnel in place...I want to have more of a federated solution?

57:49So this is where...use a[n] Active Directory Federated Services.

57:55So in this case, you have a browser making a request against Windows Identity

58:02Identity Foundation says, hey, you don't have the token that I need to get access.

58:06Browsers bounce back to his system, goes against the ADFS server, Active Directory Federated Services.

58:13It's the domain controller, has now a token to pass on to the browser; browser then passes it on to this little agent in front of the product...

58:23...and then you have some security in front of it.

58:26So this actual scenario we're working on validating.

58:32Amazon actually has worked with Microsoft to do a pretty good write-up of four or five different scenarios over the last couple months.

58:40So there's some links to those guides later on in this presentation.

58:45So some product-specific guidance...ArcGIS Server for...on Amazon EC2.

58:49You get an AMI that's not hardened beyond the Windows 2008 server defaults.

58:55We're looking into potentially providing a security-hardened AMI.

59:00You need to tell me your benchmark requirements for that, so if you have a strong need for that, let me know.

59:07There's also basic Esri online help guidance...

59:11...and Amazon has that security best practices guide that they released at the beginning of this year.

59:18For the ArcGIS.com sharing environment, Arc...

59:21...there's online help for sharing in content, parti...participating in groups, similar type of security model as Facebook.

59:29We recently went through a SAS 70 review of Esri's hosting services...

59:37...to help ensure we're providing the right type of robust security environment for your needs.

59:43And we have an upcoming Esri geospatial cloud security...cloud computing security white paper coming out.

59:50Hoping to get that out before the end of 2010.

59:55So with that, enough of cloud computing.

59:58So a little bit about mobile phone security.

1:00:01So with more platforms, be it ArcPad, Mobile, iPhone, Android...more functionality, larger user base...

1:00:08...this leads to increased hacker attention, so this is an interesting spatial analysis of hacking attempts.

1:00:14Via one, on the left, is via Bluetooth, so what you'll see is that...

1:00:20...in Bluetooth, it exponentially grows once it hits a densely populated area...

1:00:25...it's proximity-based attacks. Bluetooth, you need to be within...I don't know...is it 20...20 yards of another phone for it to attack...

1:00:36...versus a message which you could send out to a whole bunch of systems...

1:00:39...which would be more distributed widel...in a wider scenario.

1:00:43It's not dependent on a population density.

1:00:48Mobile phone security, so for ArcPad. You have this AXF data file for password protecting, encrypting it.

1:00:55You have the individual memory cards, SD memory cards; you want to encrypt those.

1:01:00ArcGIS Server has user[s] and groups; you want to limit the publishers of that.

1:01:03You have various interconnects...

1:01:05...Internet connections out there; you want to secure the ArcPad synchronization traffic occurring.

1:01:12For Mobile, you have that geodata service, you can utilize SSL; VPN tunnel's another option.

1:01:18About 10 to 20 percent of our customers use VPN tunnels.

1:01:22Utilization of the token service can be incorporated, also for Web services you can prodect...protect via credentials...

1:01:31...or filter by the operating system, the IP of the device.

1:01:34There's also a unique identifier on each one of these mobile devices.

1:01:39And if you know much about security, you would know also like...

1:01:43...all the iPhones' compromise was along that same unique identifier...

1:01:48...not iPhones. That was the iPad, wasn't it?

1:01:51The iPad attack was all based on the unique identifier...getting everybody's e-mail addresses of whoever had an iPad and that.

1:02:00So encrypting data at rest...you can also do that via the Windows Mobile Crypto API.

1:02:06And there's a variety of third-party tools for encrypting the entire storage system.

1:02:12So hopefully, I didn't rush you too much, but...

1:02:17So in designing an enterprise GIS security strategy, you first need to start out by identifying your security needs.

1:02:24Assessing your environment and starting to map out how you fit relative to...to these patterns that I've talked about today.

1:02:31You need to understand your current security trends, what's going on on there, what might be affecting you over the next year...

1:02:37...or two or three...understanding your various security options.

1:02:40Go ahead and check out the Enterprise GIS Resource Center...

1:02:43...for enterprise-wide deployment mechanisms and application-specific options...

1:02:49...and then implement security as a business enabler. Improve...you want to improve appropriate availability of information.

1:02:56Your goal is not to be the wet blanket in the organization, locking everybody down.

1:03:04So if you need more information on the technical specifics of how to implement ArcGIS Server's security function...

1:03:12...there's a Microsoft .NET Framework session on Wednesday and Thursday.

1:03:17Java session was canceled but we'll be posting the...into the Enterprise Resource Center a link for the DevSummit presentation for Java.

1:03:26And we also have a Professional Services offering for a[n] enterprise GIS security review.

1:03:33A variety of resources that I won't have you go through right now because that would be quite intense.

1:03:40But I would like to leave it open for making sure I get from you as much as possible where you need to hear more security guidance out of Esri.

1:03:51And that is it for today, thank you.
