The headlines are very discouraging. Capitalism does not guarantee wealth and success all the time. The talking heads on TV blame the greed in the stock market. I wish stock market is made of just computers that are not greedy human beings. These are bound to happen when there are human beings that participate! Money flows will eventually correct itself  I hope, capitalism will be healthy again. This will take time. I am not an economist, but I do understand that people part with money for a period of time to collect higher return in the horizon based on their aptitude for risk.  Simple is it not! But, all these complex financial instruments and its machinations seem to blur the reality and make even the brainiest act dumb - or are they just plain greedy?

Setting the context for this post, it is a tough economic situation all over the world. IT spending has reduced and will reduce significantly. In one of earlier posts, I had referred to information security as an overhead of an overhead (IT). What is a good approach for security practice in this type of economy?

I don't have a magic wand to pull a rabbit out of a hat. I have always been told that: tough economy is the time for real smart people to make money. Coming back to information security topic, with a bit of common sense, it is wise for information security professionals to offer services in those areas that does not involve capital expenditure. As a Security Manager, you may be already aware that your people are willing to go an extra mile in the current economic times.

- No budget or lack of budget, means no new capital expenditure. Spend time wisely in building a future technology strategy and keep it in the back pocket when the economy turns around.

- This is a good time to create roles/responsibilities and ownership for various areas. Create operating procedures. Make your team to automate tasks. This will help your operations become more efficient.

- This is time for security awareness  education. Create pamphlets/brochures/presentations for an online or classroom training. Engage your and your team's time to impart training.

- Leverage already invested technology platforms. Leverage utilized features that reduce costs. If you have already invested in technology such as VMware, this is the time to get the best out of it. You can use VMware's toolkit to build your lab and staging environment and optimize on hardware cost.

- Off shoring has been the mantra of senior executives, this is the time to revisit those services and measure their performance closely and assess your satisfaction level. This is a good time to build a case for not off shoring if it makes sense.

- Companies are more vulnerable in bad economic times. You are in a better position to influence senior management about information security risks under these circumstances and drive home the value of protecting your intellectual property under these kinds of circumstances. management will be all ears for such a pitch.

- Time to engage your architect to optimize your security architecture, revisit standards and optimize design for cost efficiency.

- Revisit various controls and see if there are some risks that you could optimize spending on.

- Training budget is an unfortunate victim of this type of economy. Encourage employees to take free webinars offered by various security vendors and encourage them to share the summary across the team. This will put your employees in touch with latest happenings in security at the same time there is some learning that is imparted despite zero training budget.

- Since there are very few projects in action, this is a good time to have conversations with cross functional teams and educate them about your services and solicit feedback on how to do better.

- Revisit your vendor logistics and identify whether you can renegotiate some of your already existing contracts.

The above are some good ways by which you can optimize costs, this will also enhance your team's competence level in the long run. And this approach is better than letting people go, if you can pull this.

Following the previous summaries of June's and July's threatscape based on all the research published during the month, it's time to summarize August's threatscape.

August's threatscape was dominated by a huge increase of rogue security software domains made possible due to the easily obtainable templates for the sites, several malware campaigns targeting popular social networking sites, Russian's organized cyberattack against Georgia with evidence on who's behind it pointing to "everyone" and a few botnets dedicated to the attack making the whole process easy to outsource and turn responsibility into an "open topic", several new web based botnet management kits and tools found in the wild, evidence that the 76service may in fact be going mainstream since the concept of cybercrime as a service is already emerging, and, of course, a peek at India's CAPTCHA solving economy, where the best comment I've received so far is that every site should embrace reCAPTCHA, so that while solving CAPTCHAs and participating in the abuse of these services in question, they would be also digitizing books. As usual, August was a pretty dynamic month for the middle of summer, with everyone excelling in their own malicious field.

01. McAfee's Site Advisor Blocking n.runs AG - "for starters"
False positives are rather common, especially when you're aiming to protect the end user from himself and not let him gain access to "hacking tools", but you're flagging security tools as badware and missing over half the SQL injected domains currently in the wild due to the fact that SiteAdvisor's community still haven't reviewed them - that's not good

02. The Twitter Malware Campaign Wants to Bank With You
Twitter, just like every Web 2.0 application, isn't and shouldn't be treated as a unique platform for dissemination of malware, since it's dissemination of malware "as usual". This particular malware campaign was not just executed by a lone gunman, but also, was taking advantage of a flaw allowing the author to add new followers potentially exposing them to the malicious links serving banker malware. For the the time being, MySpace, Facebook and Twitter accounts are the very last thing a malicious attacker is interesting in puchasing accounting data for, but how come? It's all due to the oversupply of automatically registered accounts at other popular services, whose ecosystem of Internet properties empower cybercriminals with the ability to launch, host and distribute malware in between abusing the very same company's services for the blackhat SEO campaign and redirection services. Theoretically, a distributed network build upon the services provided by a single company is faily easy to accomplish due to the single login authentication applied everywhere. A singly bogus Gmail account results in a blackhat SEO hosting blogspot account, flash based redirector hosted at Picasa, and a couple of thousands of spam emails sent automatically sent through Gmail in order to abuse it's trusted email reputation
 
03. Compromised Web Servers Serving Fake Flash Players
If aggressiveness matter, this campaign consisting of remotely injected redirection scripts at legitimate sites next to on purposely introduced malware oriented domains, was perhaps the most aggressive one during the month. Fake flash players, fake windows media players and fake youtube players are prone to increase as a social engineering tactic of choice due to the template-ization of malware serving sites for the sake of efficiency

04. Pinch Vulnerable to Remotely Exploitable Flaw
With Zeus vulnerable to a remotely exploitable flaw allowing cybercriminals to hijack other cybercriminal's Zeus botnet, private exploits targeting the still rather popular at least in respect to usefulness Pinch malware are leaking, allowing everyone including security researchers to take a peek at a particular campaign running unpatched Pinch gateway

05. Phishers Backdooring Phishing Pages to Scam One Another
Backdooring phishing pages is perhaps the most minimalistic approach a cybercriminal wanting to scam another cybercriminal is going to take. The far more beneficial approach that I've encountered on a couple of occassions so far, would be to backdoor a proprietary web malware exploitation kit, release it in the wild, let them put the time and efforts into launching the campaigns, then hijack their botnet. In fact, the possibilities for backdooring copycat web malware exploitation kits in order to take advantage of the momentum while introducing a non-existent kit has always been there at the disposal of malicious attackers. One thing's for sure - there's no such thing as a free web malware exploitation kit, just like there isn't such thing as a free phishing page

06. Email Hacking Going Commercial - Part Two
In between the scammers promising the Moon and asking for anything between $20 to $250 to hack into an email account, there are "legitimate" services taking advantage of web email hacking kits consisting of each and every known XSS vulnerability for a particular service in an attempt to increase the chances of the attacker. And given that the majority of these have been patched a long time ago, social engineering comes into play. Do these services have a future? Definitely as more and more people are in fact looking for and requesting such services, in fact, they're willing to pay a bonus considering how exotic it is for them to have any email that they provide hacked into and the accounting data sent back to them

07. The Russia vs Georgia Cyber Attack
Event of the month? Could be, but just like every "event of the moth" everyone seems to be once again restating their "selective retention" preferences. What is selective retention anyway? Selective retention is basically a situation where once Russian is attacking another country's infrastructure, you would automatically conclude that it's Russian FSB behind the attacks and consciously and subconsciously ignore all the research and articles telling you otherwise, namely that the FSB wouldn't even bother acknowledging Georgia's online presence, at least not directly. Moreover, talking about the FSB as the agency behind the cyberattacks indicates "selective retention", talking about FAPSI indicates better understanding of the subject.

In times when cybercrime is getting ever easier to outsource, anyone following the news could basically orchestrate a large scale DDoS attack against a particular country in order to forward the responsibility to any country that they want to. In Russia vs Georgia, you have a combination of a collectivist society that's possessing the capabilities to launch DDoS attacks, knows where and how to order them, and that in times when your country is engaged in a war conflict drinking beer instead of DDoS-sing the major government sites of the adversary is not an option.

Selective retention when combined with a typical mainstream media's mentality to "slice the threat on pieces" instead of turning the page as soon as possible, is perhaps the worst possible combination. Furthermore, coming up with Social Network analysis of the cyberattacks would produce nothing more but a few fancy graphs of over enthusiastic Russian netizen's distributing the static list of the targets. The real conversations, as always, are happening in the "Dark Web" limiting the possibilities for open source intelligence using a data mining software. Things changed, OPSEC is slowly emerging as a concept among malicious parties, whenever some of the "calls for action" in the DDoS attacks were posted at mainstream forums, they were immediately removed so that they don't show up in such academic initiatives

08. 76Service - Cybercrime as a Service Going Mainstream
The reappearance of the 76Service allowing everyone to log into a web based interface and collect all the accounting and financial data coming from malware infected hosts across the globe for the period of time for which they've bought access, indicates that what used to be proprietary services which were supposedly no longer available, are now being operated in a do-it-yourself fashion. Goods and products mature into services, so from a cost-benefit analysis perspective, outsourcing is naturally most beneficial even when it comes to cybercrime

09. Who's Behind the Georgia Cyber Attacks?
If it's the botnets used in the attacks, they are known, if it's about who's providing the hosting for the command and control, it's the "usual suspects", but just like previous discussion of the Russian Business Network, it remains questionable on whether or not they work on a revenue-sharing basis, are simply providing the anti-abuse hosting, or are the shady conspirators that every newly born RBN expert is positioning them to be.

Cheap conversation regarding the RBN ultimately serves the RBN, and just for the record, there's a RBN alternative in every country, but the only thing that remains the same are the customers, tracking the customers means exposing the RBN and the international franchises of their services, making it harder to identify their international operations. And given that the "tip of the iceberg", namely RBN's U.S operations remain in tact, talking about taking actions against their international operations in countries where cybercrime law is still pending, is yet another quality research into the topic building up the pile of research into the very same segments of the very same ISPs.

Just for the record - these "very same ISPs" are regular readers of my blog, and if you analyze their activities, they're definitely reading yours too, ironically, surfing through gateways residing within their netblock that are so heavily blacklisted due to the guestbook and forum spamming activities that their bad reputation usually ends up in another massive blackhat SEO campaign exposed.

10. Guerilla Marketing for a Conspiracy Site
Conspiracy theorists may in fact have a new wallpaper to show off with

11. Banker Malware Targeting Brazilian Banks in the Wild
When misinformed and not knowing anything about a particular underground segment, a potential cybercriminal would stick to using such primitive compared to the sophisticated banker malware kits currently in the wild. These sophisticated banker malware kits are often coming in a customer-tailored proposition, with their price increasing or decreasing based on the specific module to be included or excluded. For instance, a module targeting all the U.S banks that has been put in a "learning mode" long before it was made available to the customers can be requested and is often available with the business model build around the customer's wants 

12. Compromised Cpanel Accounts For Sale
Despite the massive SQL injection attacks, accounting data for Cpanel accounts coming from malware infected hosts seems to be once again coming into play, which isn't surprising given the filtering capabilities and log parsing tools today's botnet masters are empowered with. These very same compromised Cpanel accounts and the associated domains often end up so heavility abused that it's tactics like these that are driving the underground multitasking mentality, namely, abusing a single compromised account for each and every malicious online activity you can think of - even hosting banners for their blackhat SEO services

13. A Diverse Portfolio of Fake Security Software - Part Two
In August we saw a peek of fake security software, neatly typosquatted domains whose authors earn revenue each and every time someone installs the software. The vendors behind this software are forwarding the entire process of driving traffic to those excelling in aggregating traffic and abusing it. As anticipated, underground multitasking started taking place within the fake security software domains, with the people behind them introducing client-side exploits in order to improve the monetization of the traffic coming to the sites

14. DIY Botnet Kit Promising Eternal Updates
There's no such thing as a (quality) free botnet kit. What's for free is often the leftovers from a single feature of a more sophisticated proprietary botnet kit. This one in particular is however trying to demonstrate that even a plain simple GUI botnet command and control software can achieve the results desired by an average script kiddie, and not necessarily satisfy the needs of the experienced botnet master

15. A Diverse Portfolio of Fake Security Software - Part Three
As far as trends and fads are concerned, the majority of the domains are currently parked at up to four different IPs, with most of them going into a stand by mode once they get detected and reappear back couple of weeks later

16. Fake Celebrity Video Sites Serving Malware - Part Two
Due to the template-ization of fake celebrity video sites, and simple traffic management tools combined with blackhat SEO tactics, these sites are also prone to increase in the next couple of months

17. Web Based Botnet Command and Control Kit 2.0
It's releases like these that remind us of the amount of time, efforts and personal touch that a malicious attacker would put into such a management kit, currently acting as a personal benchmark as far as complexity and features indicating the coder's experience with botnets is concerned. What's he's failing to anticipate is that this kit is sooner or later going to turn into the "MPack of botnet management"

18. A Diverse Portfolio of Fake Security Software - Part Four
Keep it coming, we'll keep it exposing until we end up getting down to the "fake software vendor" itself

19. Automatic Email Harvesting 2.0
Email harvesting is slowly maturing into a vertically integrated service provided by vendors of managed spamming services. This email harvesting module is aiming to close the page on text obfuscation in respect to fighting spam, and is successfully recognizing and collecting such publicly available emails. From a psychological perspective though, the end users who bothered to obfuscate their emails are less likely to fall victims into phishing scams, with the obfuscation speaking for a relatively decent situational awareness on how they emails end up in a spammer's campaign

20. Fake Porn Sites Serving Malware - Part Three
As a firm believer in sampling in order to draw conclusions on the big picture, an approach that has proven highly accurate in modeling historical and upcoming tactics and behavior, a single fake porn site serving malware campaign usually exposes a dozen of misconfigured redirectors, which thanks to their misconfiguration despite the evasive features available within the kits, expose another dozen of malware campaigns

21. Facebook Malware Campaigns Rotating Tactics
With no particular flaw exploited other than the social engineering tactic of using already compromised Facebook accounts who would automatically spam all their friends with links to flash files hosted at legitimate services, the more persistent the campaign is, the higher the chance that it will scale enough. This campaign in particular is mainly relying on rotation of tactics, namely different messages, different services and file extensions used in order to trick someone's friend into visiting the URL. With the number of users increasing, the most popular social networking sites are naturally going to be permanently under attacks from cybercriminals

22. Fake Security Software Domains Serving Exploits
Despite that it's a single brand, namely the International Virus Research Lab that's introducing client-side exploits within it's portfolio of domains, the opportunity for abuse may be noticed by the rest of the brands pretty fast

23. Exposing India’s CAPTCHA Solving Economy
Taking into consideration the mentality surrounding a particular country's cybercriminals, how they think, how they operate, what do they define as an opportunity, and how much personal efforts are they willing to put into their campaigns, I wouldn't be surpised if a Russian vendor offering 100,000 bogus Gmail accounts for sale has in fact outsourcing the account registration process to Indian workers, paid them pocket change and is then reselling them ten to twenty times higher than the price he originally paid for them.

The text based CAPTCHAs used at the major Internet portals and services, are so efficiently abused by this approach that continuing to use is directly undermining the trust these email providers and services often come with as granted

Among the main differences between a professional botnet command and control kit, and one that's been originally released for free, is the quality and the clearly visible experience of the kit's programmer in the professional one.

A Chinese hacking group is offering the moon, and asking for nothing. And in times when a cybercriminal can even monetize his conversation with a potential customer by telling him he's actually consulting them and barely talking, is this for real and how come? This "Robin Hood approach" on behalf of the group could have worked an year ago, when greedy cybercriminals were still charging hundreds of thousands of dollars for their sophisticated banker malwares. Today, most of them leaked in such a surprising, and definitely not anticipated on behalf of the malware coders way, that not only they stopped offering support and abandoned their releases, but what used to be available only to those willing to open their virtual pocket and transfer some virtual currency, is available to everyone making such free botnet kits irrelevant - mostly due to their simplicity speaking for zero quality assurance we can see in professional kits.

Once the dust settles on this populist underground release, its potential users would once again return to their localized copies of web based botnet command and control kits.

Today, allow me to update you on FAIR and the movement towards a formal, open standard.  There’s a couple of cool things going on in our little risk-world.

First, The Open Group Security Forum continues to move towards a formal adoption of FAIR.

WHAT DO YOU MEAN “WE” - YOU GOT A STANDARDS BODY IN YOUR POCKET OR SOMETHING?

Our meeting in Chicago a few weeks ago was great, but also slightly disturbing for me. I got pronoun-confusion syndrome.   I’m used to using the “we” pronoun to refer to RMI, or Jack and myself as we vet the models.  So without even thinking I would said “we have been looking at how loss occurs, and may want to change the model some” and The Open Group Members freaked out (rightfully so).  Adrian Seccombe gently reminded me that the “we” was now the Security Forum, and that “we” didn’t go changing things at will without vetting against each other.  Man I love this stuff.  I get to run our thoughts and ideas past some great folks now - you know, those smart people who tend to have really complex problems and are trying hard to solve them.

Formal Adoption:  Soon, Very Soon Now

Formal Adoption basically means we’ve made this document, everyone is close to saying that they generally like it, and once that finally happens then “bam”, we’re ready to move onward and upward with better things (see Cookbooks, below).  We’ve got a couple of changes to the current document that have been requested that aren’t a big deal.  For example, one request is that we make some statement about general applicability of FAIR to risk domains outside of the IT realm.   But once additions like that and others are done, this long process should be complete.

New Document Moving Towards Public Release:

We’ve got a basic document that should be public in the next few weeks on “What Makes a Good Risk Assessment Methodology” - written by yours truly and Jack.  It’s a very high-level document, and serves two purposes:

  • For novices it helps parse out what is important in any undertaking to understand corporate risk (the repeated discussions on the ISO 27001 mailing list make me think it would be a place ripe for such a document).
  • For those who “know” risk, it helps to re-establish some fundamental principles like the use of scales (ratio, please), the implications of dealing in probabilities, what attributes like consistency and defensibility mean, how “risk” should be reported to the business (something you know, meaningful) and so on.

When this doc is deemed ready for public consumption I’ll be sure to post on this blog here.

COOKBOOKS, EUROPEAN AGENCIES, AND, IRON CHEF “RISK” - WHOSE CUISINE WILL REIGN SUPREME?

One interesting thing that came up in the Chicago meeting was that ENISA (The European Network and Information Security Agency) developed a very nice document that reviewed something like 18 different risk assessment methodologies against their Criteria for Goodness.  FAIR was one of the ones they reviewed, and we (the royal “we” used there to include all us FAIR-Folk) did awfully well.  Things of interest:

  1. They based their work on the current introduction paper which is not at all a step-by-step guide towards an organizational risk assessment (what ENISA really wanted) and we did pretty well.  Well enough that if we had developed a paper along the lines of NIST 800-30 or OCTAVE for the use of FAIR in a formal process, we could have done really, really well.  Like won-the-bake-off kind of well.
  2. FAIR is actually not at all incongruous to many of the risk assessment methodologies offered, and in fact compliments many of them by letting those methodologies develop real, structured probabilities.  Think OCTAVE, where they basically say “math is (probabilities are) hard, so if you want to do them for reals, good luck!  But here’s a nonsensical way to do things if you want to believe in magic-fairy risk“.  FAIR fits right in there by stomping on the magic-fairy risk with the jack-boots of rationality.  FAIR similarly helps other risk standards that might lack structured probability development.

So The Open Group Security Forum decided that though we could create a new document and totally p0wn any future ENISA bake-off, there wasn’t much demand for the development of that documentation by the membership  - a point which was made quite apparent at the beginning of the discussion when one large European company CISO asked “What’s ENISA?”  Relevancy is everything, I suppose.

But that second item up there - the one about helping rather than competing with other “risk assessment methodologies” - really struck a chord.  So “we” (The Security Forum) are going to develop some “Cookbooks” that basically are high-level documents that say “If you want to use FAIR with (OCTAVE/COSO/CoBIT/Whatever) here’s how it fits, makes it better, and improves your life.  I’m pretty excited about these, and our first document looks like it’s going to be COSO integration.

THE OPEN GROUP SECURITY FORUM - THEY’RE A TRUSTING BUNCH (WITH QUALIFICATION, OF COURSE)

Finally, many people have asked me “Why work with The Open Group?”  There are many reasons, to be sure, but I will give you one example.  Members of the Security Forum there are not only great at vetting the model and getting consensus on risk and risk factors - but they’re quick to start applying.  So in Chicago, I thought I’d be talking about FAIR and the standard and fighting groupthink.  Nope.  Not at all.  In fact, the forum members spent more time suddenly discussing use of FAIR in a new Trust Model they’re developing.  So all of the sudden, I’m part of a new and exciting project to develop a Trust Model - how cool is that?  While formal adoption of the Trust Model will be necessarily long and deliberate - the collaboration and development is happening much faster than I can keep up with.  But if you all will allow me, it will help me get my head around it all by blogging about it later this week.  So be prepared to read about me dealing in “Trust” a little bit.

The U.S. government has published its policy: they can take you laptop anywhere they want, for as long as they want, and share the information with anyone they want.

Here's the actual policy:

Federal agents may take a traveler's laptop or other electronic device to an off-site location for an unspecified period of time without any suspicion of wrongdoing, as part of border search policies the Department of Homeland Security recently disclosed. Also, officials may share copies of the laptop's contents with other agencies and private entities for language translation, data decryption, or other reasons, according to the policies, dated July 16 and issued by two DHS agencies, US Customs and Border Protection and US Immigration and Customs Enforcement... DHS officials said that the newly disclosed policies — which apply to anyone entering the country, including US citizens — are reasonable and necessary to prevent terrorism... The policies cover 'any device capable of storing information in digital or analog form,' including hard drives, flash drives, cell phones, iPods, pagers, beepers, and video and audio tapes. They also cover 'all papers and other written documentation,' including books, pamphlets and 'written materials commonly referred to as "pocket trash..."

It's not the policy that's amazing; it's the fact that the government has actually made it public.

Slashdot thread. My previous essay on crossing borders with laptops, and how to protect yourself.

Although honestly, the best thing is probably to keep your encrypted archives on some network drive somewhere, and download what you need after you cross the border.

And you know what? Maybe they are right :-)

When I was a sole sysadmin for a small ISP, I didn't share my passwords with management either. They never asked ... but that is not the point. I would not have passed "a bus test", which is "will a business still run if a sysadmin is hit by a bus" [or, "goes rogue", by whatever definition of "rogue"]

Keeping all this in mind, will you accept if you bank closes doors until they can figure out what the password is on their database? Didn't think so ...

So, my point was that, in my opinion, it is an unacceptable risk for all but the smallest organizations to have one person who have the power to control access to critical systems AND to place no controls (neither monitoring, auditing nor preventative) on his activity.

AND that is why, back in my ISP days, one day a boss came to me with an old ragged notebook and said "write down the passwords here." I did. The notebook went back into his pocket (and then, presumably, in some more "secure storage," like the back of his closet at home or something :-))

It needs to get out so other young girls and their parents can learn from this tragedy.

I traveled to China last year on a two week business trip. One of the thoughts that struck me was that it appeared to be a very law abiding society. Then when I visited Tiananmen Square, I was reminded of the scene when Government tanks turned on young student protestors and masacared them. There is much about China that lays beneath the surface.

Diana O'Brien was a young model from Canada who was lured to China with promises of "catwalk" modelling opportunities. Once she arrived there, the opportunities became offers to dance in bars. Apparently, many young girls go to China thinking they are breaking into the big time when in reality, many of these modelling agencies inlvolve little more than an apartment and a cell phone.

The JH model managment company that Diana worked for disappeared when news of her murder broke. Their website was taken down on Thursday. Although an official from the State Security Bureau would not comment, her murder seems to have been committed by a street criminal who stabbed her to death near her apartment for her belongings.

Young women and the parents of young women, need to know what they are getting themselves into before they travel to a strange place and put their lives in the hands of people who see them merely as a way to make money. This coming in the wake of the summer Olympics might cause some to question their own saftey in Beijing. Some of the age old principles still hold true; Beaware of your surroundings, Never travel alone - always have at least one companion at all times, Always let people know where you are going, Carry a cell phone (and pepper spray it is is allowed)to enable you to call for help.

In the streets of Beijing and Shanghai, people will approach you all of the time trying to get you to buy; fake watches, perfume, stamps and many other things. Most of these people are legitimately trying to make a sale but you do not know who are the ones that may be trying to pick-pocket you or surround you to rob you or lure you off a busy street where you won't be seen so easily. Walk briskly past them and ignore them. You should shop whee you are not being hassled and therfore can concentrate on your safety.

Well, ok, no actual rumors, but hey, one can dream, huh? My spring calendar was full of events in Asia and Australia, then TechEd US seemed to suddenly appear out of nowhere! So I've been kinda swamped. I've missed writing here; it's good to get back into the swing.

At TechEd this year, I gave a presentation called "21st century networking: time to throw away your medieval gateways." (Actually, I've given this same talk before, at events in Amsterdam, Brussels, Oslo, and numerous on-campus customer meetings. It's time to bring the knowledge to the masses.)

I described an idea of using IPv6, IPsec, NAP, and group policy to build a pretty slick replacement for clunky VPN gateways. Turns out we've been piloting this very idea on our internal corpnet. Like a good little bunny I got myself enrolled in the thing and -- pardon the unattractive gushing -- this thing rawks! Here's a brief rundown of the parts you'd configure on managed clients:

  • Windows Vista Business (with Software Assurance), Enterprise, or Ultimate editions
  • That are domain-joined
  • Users run as non-admin
  • Group policy applies numerous settings
  • UAC is enabled
  • BitLocker is configured to protect confidential information stored offline
  • The Windows Firewall is enabled
  • NAP is used for checking health
  • Forefront Client Security for keeping malware off the box
  • Smart cards for strong authentication of users
  • IPsec is required for connection authentication and traffic encryption
  • IPv6 is required for worldwide Internet connectivity
  • A DNS suffix search list represents the data center name space
  • Static IPv6 DNS servers provide name resolution for hosts in the data center

What does this give you? True anywhere access, anywhere in the world, directly to corpnet resources from managed and secure client PCs. The Internet has replaced private WAN links for good reason: enormous cost benefits. The only thing holding us back from fully utilizing this development has been a lack of way to enforce and monitor the security of clients not physically located within the corpnet. Well, those days are over. Now you can build PCs that are trusted just as if they were on the corpnet, without knowing or caring anything about the underlying network connections. And let me tell you, it's as addictive as a few other substances I could mention, but will refrain, since this is (I hope) a family blog :)

Maybe you've heard of the notion of "deperimeterization." Taken to its extreme, I think it's a bit silly. To put a SQL Server directly on the Internet is just plain stupid -- not because I don't think I could keep it protected, but simply because that's unnecessary risk. Only my web server -- and no one else -- should be talking to my SQL Server. But that web server will be in the same subnet as the SQL Server, and IPsec policies used also here will govern who can connect to the SQL Server. Warning to any and all network DMZs: your days are numbered!

Shrink your perimeter to that which really matters -- your data center. All your clients live (as we would say in the olden days) "on the outside of the firewall." Now then, there are two kinds of clients. Managed clients, as I described above, establish IPsec-authenticated/encrypted, group-policy-configured, NAP-enforced IPv6 connections directly to corpnet resources without going through any kind of access gateway. The router connecting you to your ISP is fully sufficient for blocking denial of service attempts. Be sure to follow my advice in "Configure your router to block DOS attempts," and then add two more rules to permit incoming port udp/500 and IP protocol 50 over IPv6. That's it. No NATing or other unnatural network acts are required (finally, you can stop lying to your significant other about why you squirrel yourself away in the computer room all those weekend nights).

Unmanaged clients will continue to use IPv4 to access published Web and Win32 applications through a gateway like IAG. Since you can't trust these clients nor can you trust the data they're throwing at you, you have to inspect and validate at the perimeter. You can take advantage of IAG's application-modifying capabilities to "wrap" security around poorly-written web apps; you can even download an ActiveX control to unmanaged clients to perform some basic health checking, policy enforcement, and cache clearing. None of these eliminates the final requirement to continue inspecting and removing malware from servers where users store data: Exchange, SharePoint, Office Communications Server, and file servers.

Machines are mobile, data is mobile. The mainframes and large desktop PCs of the past posses an effective security attribute: the heaviness of the machines. You couldn't easily saunter out the front door with a PC-AT in your pocket! These days, we all line our pockets with tiny little mobile phones stuffed with 16GB of storage. It's now a fact: data moves. And like water, data moves wherever it can, as rapidly as it can, often beyond your control if you don't prepare for that. With properly-configured and managed clients we can enjoy a single access and authentication experience no matter where the computer is physically located. For example: I can sit in my house and enter '"http://internal-web-site-name" in my browser. The DNS suffix search list adds the appropriate suffix, my browser's resolver performs an IPv6 name lookup, and my computer makes an authenticated and encrypted connection, after it meets the NAP policy, directly to that internal server. Very nice. As far as I'm concerned, there's no difference between the Internet and my corpnet. It's all just there.

For a while now many of you know I've been speaking and writing, mostly at the conceptual level, about the day when such a way of remote computing will arise. Well, my friends, that day is now. You can indeed build it now, with the products you have. I won't admit it's all peaches and cream: there's a fair number of moving parts here, it's true. But most of these moving parts are parts you're already familiar with: I'm simply encouraging you to move them in a specific way. You'll need to do some custom scripting for client-side connection diagnostics, but that's about it.

My next step is to create a more detailed guide, which I plan to publish through TechNet Magazine. I'm targeting (but not promising) the October issue. The article will include greater details about configuring your infrastructure to support the managed clients I describe.

I've lost track of the swelling number of individual conference attendees and the plethora of email writers who've expressed a desire to build this in their own environments. The one common thread from everyone is "I want to do it now!" Folks, it's really pretty exciting for me to see so many of you ready to cross the chasm from the perdition of paleo-networking (layer upon endless, complex layer of DMZs) into the paradise of flat, simple, cheap, and secure access to information. If you haven't yet, please take the time to read through some of our information (especially Scott Charney's paper) on end-to-end trust. Friends, the idea I describe above is the plumbing for realizing the end-to-end trust vision.
