So to that end I would like to start by thanking all of our friends on Wall Street and here in Washington DC for providing such a rich tapestry of recent events that I can speak to.</div><br /><div>Like many people in this industry, my focus on security was fundamentally altered by Dan Geer&#39;s speech &quot;Risk Management is Where the Money Is&quot;[1], there are not many people who can call a ten year shot in the technology business, but Dan Geer did. The talk revolutionized the security industry. Since that speech, the security market, the vendors, consultants, and everyone else has realized that security is really about risk management.</div><br /><div>Of course, saying that you are managing risk and actually managing risk are two different things. Warren Buffett started off his 2007 shareholder letter [2] talking about financial institutions&#39; ability to deal with the subprime mess in the housing market saying, &quot;You don&#39;t know who is swimming naked until the tide goes out.&quot; In our world, we don&#39;t know whose systems are running naked, with no controls, until they are attacked. Of course, by then it is too late.</div><br /><div>So the security industry understands enough about risk management that the language of risk has permeated almost every product, presentation, and security project for the last ten years. However, a friend of mine who works at a bank recently attended a workshop on security metrics, and came away with the following observation - &quot;All these people are talking about risk, but they don&#39;t have any assets.&quot; You can&#39;t do risk management if you don&#39;t know your assets.</div><br /><div>Risk management requires that you know your assets, that on some level you understand the vulnerabilities surrounding your assets, the threats against those, and efficacy of the countermeasures you would like to use to separate the threat from the asset. But it starts with assets. Unfortunately, in the digital world these turn out to be devilishly hard to identify and value.</div><br /><div>Recent events have taught us again, that in the financial world, Warren Buffett has few peers as a risk manager. I would like to take the first two parts of this talk looking at his career as a way to understand risk management and what we can infer for our digital assets.</div><br /><div>Warren Buffett&#39;s evolution as an investor can be broken up into two parts. He began his career very much influenced by Ben Graham, who sought to buy &quot;cheap stocks&quot;, comparing the price of the stock to value of the company&#39;s assets, and placing many, diversified bets on companies whose share price was below the total assets. Note that the businesses may have been of unremarkable quality, but when the price was right Graham would buy in, wait for it to rise and then sell. This was the dawn of value investing.</div><br /><div>Buffett&#39;s later career departed from Graham&#39;s strict, statistical measures, where he sought to buy into companies that were selling at a fair price, but were also high quality businesses. We will examine high quality in Part 2 of this talk, but first we go to Part 1 which is asset value.</div><br /><div>Why does a talk on finding and fixing vulnerabilities start with valuing assets? The reason is that vulnerabilities are everywhere, we are literally marinating in them. Interesting vulnerabilities are attached to high value assets. In a world that quite literally presents us with too much information, we need screens to sift out what is worth paying attention to. &#0160;You can run your vulnerability assessment tool of choice on your system, and come back with hundreds or thousands of vulnerabilities, but which ones should you pay attention to and act on? The first part of answering this question is asset value.</div><br /><div>When Warren Buffett was 19 years old studying at the University of Nebraska, he read Ben Graham&#39;s book &quot;The Intelligent Investor&quot;, Buffett said he thought it was the best book on investing he has ever read and still feels that way today. In the Intelligent Investor Graham lays out the framework of value investing. Specifically, Graham talks about three concepts - Mr. Market, a stock is a piece of a business, and Margin of Safety.</div><br /><div>Mr. Market is a fictional, teaching device invented by Graham. You imagine that you have a somewhat manic depressive business partner called Mr. Market. Every day, Mr. Market comes into the office and offers you quotes on companies, some days he is in a good mood and the prices are high, other days he is gloomy and prices are low. The market is a quote machine, for quoting prices, not a value assessment machine. Your job is to wait for the right price, and you are free to take as many passes and be as patient as you would like, Mr. Market will just show up the next day and throw out a new price.&#0160;</div><br /><div>Graham used Mr. Market to teach us the separation between a price of a stock, and the value of a company. The second big concept from Intelligent Investor is that buying a stock is buying a small piece of the underlying business. You are not buying a roulette chip, or a number that fluctuates in the newspaper every day, rather you are buying a piece of the company&#39;s existing and future cash flow. What the stock market says General Electric is worth yesterday, today or tomorrow is separate from GE&#39;s actual ability to generate cash flow.</div><br /><div>The last big concept in &quot;The Intelligent Investor&quot; and the one seemingly most applicable to information security is the Margin of Safety. Graham&#39;s margin of safety involved calculating the intrinsic value of a business and then buying stock where the market cap of a company is less than its intrinsic value. So if a company has $100 million in assets and a market capitalization of $75 million, then an investor would get a 25% margin of safety. Ideally, Graham wanted to buy stocks that were selling for one half of their book value, i.e. with a 50% margin of safety. Graham said that buying stocks without a margin of safety, above their book value, speculation, not investing.</div><br /><div>So price is readily available, but how do we calculate intrinsic value so that we can ascertain the margin of safety? Graham used quantitative statistical measures, relying heavily on the company&#39;s book value, like its hard assets. What would it take for a competitor to reproduce the company&#39;s assets - its factories, distribution system, and so on. The difference between the book value of the assets and market cap is the margin of safety.</div><br /><div>What can we learn in information security from this quantitative approach? Where price and value are readily ascertainable we should build countermeasures and eliminate on vulnerabilities that give our assets a wide margin of safety. Since budgets are not unlimited we should prefer vulnerabilities that are cheap to find, cheap to fix.</div><br /><div>First to the asset question, information security budgets like all IT budgets are crufty, they are not a reflection of today&#39;s top issues and priorities so much as an accumulating snowball of decisions, legacy contracts, and solution attempts to yesteryear&#39;s problems. Today the normal Information Security budget is just a legacy artifact from bygone years when the network was the purported greatest vulnerability. If you were around in 1995, you remember the great gnashing of gears as the enterprises opened up their networks, connected their back ends to the Web and began to transact business in the giant virtual space.</div><br /><div>The security people huffed and puffed that it was dangerous but there was simply too much money to be made, so businesses went ahead. The security people would not go down without a fight and insisted on countermeasures. They got two - the network firewall and SSL. The firewall was used to separate the average Fortune 500s network of hundreds of thousands of machines, employees, consultants, and partners from the web at large. SSL was used to protect the network channel between the web server and the client browser. so the network firewall separated the network segments, and SSL in effect encrypted the last mile of many million complex transactions and computations.</div><br /><div>In 1995, this seemed like a good security architecture. When we built out these security architectures, the eCommerce market was derided as a toy. Amazon famously lost money for years - losing a little on every transaction but making it up in volume. When the market is nascent, a quaint security architecture offers cost effective protection. But what about 2008? Those cute little eCommerce buggers have grown they even make profits now - market caps measured in the tens of billions, accumulating large cash hordes, no debt, and the largest ones are in better financial shape than the financial services players that kicked sand in their face in the dotcom era.&#0160;</div><br /><div>And its not just eCommerce, the &quot;real&quot; economy Fortune 500 types are all connected as well. Directly and indirectly the Web is seeping into all businesses. Major changes from when the security architecture of the web was built out. But has the security architecture changed to reflect these new business realities? Not a bit of it!</div><br /><div>We can use the book value of the IT budget investments and the book value of the Information Security investments to see what kind of Margins of Safety Information Security groups are engineering.</div><br /><div>Let&#39;s look at some market data, Gary McGraw reviewed the numbers [2] in software security for 2007, breaking down software security sectors like tools and services. Here is a summary of his findings on software security tools:</div><br /><div>&quot;One of the most important developments in the software security market can be seen in the tools space which, combined, almost doubled to $150-180 million. Top of list are two major acquisitions that closed in 2007: Watchfire&#39;s purchase by IBM (somewhere in the range of $120-150 million on 2006 revenue of $26 million) and SPI Dynamics&#39;s purchase by HP (for around $100 million on 2006 revenue of $21.2 million).</div><br /><div>...</div><br /><div>The black box space was flat in 2007, with IBM/Watchfire checking in at $24.1 million and HP/SPI Dynamics earning $22.3 million. Smaller companies in the space, including Cenzic, Codenomicon, WhiteHat and the like had combined revenues around $12.5 million (a growth of 25%, though Cenzic grew 16% and WhiteHat 52%). Most of the growth &quot;hiccup&quot; in the black box market can be attributed to the serious challenges posed by any acquisition. So far 2008 looks to be back on track from a growth perspective in the black box testing space. The global reach that IBM and HP offer are already making a big difference.</div><br /><br /><div>On a more positive note, static analysis tools for code review grew at a healthy clip in 2007 into a $91.9 million dollar market. Fortify was up 83% to $29.2 million. Klocwork grew over 60% to $26 million. Coverity grew over 50% to $27.2 million. Ounce Labs tripled their revenue to $9.5 million.&quot;</div><br /><div>These are very nice growth numbers, what company doesn&#39;t want 83% growth? However, the let&#39;s look at the total picture and compare the software security countermeasures against other security mechanisms. Gary McGraw&#39;s estimate shows the software security space coming in at $150 Million total, yet we see a company like Checkpoint that won the network security war in 1995 with earnings of around $900 Million! One single network security vendor is 6 times bigger than the entire software security space, in what alternate universe does this make sense?</div><br /><div>This is where we begin to see that decisions in the People&#39;s Republic of Information Security have no real risk management thinking, they truly are swimming naked and hoping the tide doesn&#39;t go out.</div><br /><div>Let&#39;s look at network assets. Obviously Cisco is the biggest, they earned $39.5 Billion last year. Pretty stellar. So spending $900 Million (Checkpoint) to defined $39.5 Billion seems like a pretty good deal.</div><br /><div>Except, let&#39;s compare software security spending - last year Microsoft earned $60 Billion, SAP $16 billion, and Oracle $22 Billion. So that is about $98 Billion in just three vendors and you are going to &quot;defend&quot; that with allocating $150 Million worth of software security tools?</div><br /><div>On the network side we are buying $900 million of security countermeasures (Checkpoint firewalls) to protect $39.5 billion worth of Cisco gear, about 2.3% of the network investment goes to security.</div><br /><div>On the software side, we are buying $150 million of security countermeasures (like static analysis and black box scanners) to protect $98 billion of software (you know the stuff that runs the whole business), roughly coming to about 0.2% of the software budget goes to security.</div><br /><div>This is very disturbing. From a prioritization standpoint The People&#39;s Republic of Information Security is misaligned by an order of magnitude at least. Next time you read about a data breach, or see an auditor&#39;s report with thousands of findings you won&#39;t have to wonder how it happened. It happened because Information Security doesn&#39;t have its eye on the ball, it invests in network security not because those controls have greater efficacy (the whole point of networks is they are dumb), no, they invest in network firewalls because they bought a bunch in 1995, some more in 1998, and heck they just kept buying them, the Checkpoint rep kept showing up and taking CISOs out to play golf, contracts got renewed, and poof - there goes the security budget.</div><br /><div>Consider that software security tools could grow 50% a year for five years and still be half of where Checkpoint is today.</div><br /><div>The optimistic way of looking at all this data is that there is major room for growth for software security, if you take network security as a target for a mature industry and assume that 2.3% is a reasonable margin of safety, then the software security space should evolve to around 2% of the software space meaning that it should evolve into a $2 billion space around fifteen times larger than it is today. Unprotected assets will either be protected or will cease to be assets, VCs get your check books ready.</div><br /><div>My friend Brian Chess has a nice way of looking at this he says 2007 was the turning point - &quot;the first year there was a bigger market for products that help you get code right than there was for products that help you demonstrate a problem exists.&quot;</div><br /><div>Now I am not suggesting that Information Security budgets have to be aligned with IT budget one for one, but I do think that looking at the overall IT budget is the starting point. If Information Security has a more cost effective security mechanism they should deploy it, but the starting point should be aligned to the business. Businesses spend most of their money on software, and there are very good reasons - competitive advantage, increased revenues and lower costs. Information Security spends most of its money on network security, and there is no good reason why, except that it was a seemingly good idea in 1995. You really don&#39;t have to go beyond the book value of IT investment as a whole versus Information Security to see a stunning disparity. Information Security&#39;s job is to deliver a Margin of Safety to the business, but they are not.&#0160;</div><br /><div>To deliver a real Margin of Safety to the business, I propose the following based on a defense in depth mindset. Break the IT budget into the following categories:</div><br /><div>- Network: all the resources invested in Cisco, network admins, etc.</div><div>- Host: all the resources invested in Unix, Windows, sys admins, etc.</div><div>- Applications: all the resources invested in developers, CRM, ERP, etc.</div><div>- Data: all the resources invested in databases, DBAs, etc.</div><br /><div>Tally up each layer. If you are like most business you will probably find that you spend most on Applications, then Data, then Host, then Network.</div><br /><div>Then do the same exercise for the Information Security budget:</div><br /><div>- Network: all the resources invested in network firewalls, firewall admins, etc.</div><div>- Host: all the resources invested in Vulnerability management, patching, etc.</div><div>- Applications: all the resources invested in static analysis, black box scanning etc.</div><div>- Data: all the resources invested in database encryption, database monitoring, etc.</div><br /><div>Again, tally each up layer. If you are like most business you will find that you spend most on Network, then Host, then Applications, then Data. Congratulations, Information Security, you are diametrically opposed to the business!</div><br /><div>Its not just about alignment for alignment&#39;s sake, its about applying controls as a way to have a Margin of Safety properly placed so that when not if there is a failure on a higher value asset you are relatively better positioned to deal with it.&#0160;</div><br /><div>The pure statistical approach can only take us so far. Buffett said he would be a lot poorer if all he did was listen to Ben Graham. Book value is great to see the diametric opposition mentioned above, but it doesn&#39;t really tell us much about the efficacy of the security mechanisms.</div><br /><div>What we do get out of this statistical approach is a screen. The asset value screen filters out subjective opinion and narrows the field for where we need to dig in to do the high value, time consuming analytical work.</div><br /><div>The second part of Warren Buffett&#39;s career and the second part of this talk leave behind pure statistical measures. In Warren Buffett&#39;s case he was joined by a guy named Charlie Munger who talked him out of the pure Ben Graham approach. Charlie Munger has a saying - &quot;a great business at a fair price beats a fair business at a great price.&quot; Where Graham was focused on price and margin of safety, Munger wants a fair price but also a high quality business. This lead to Warren Buffett&#39;s company Berkshire Hathaway investing in companies like Coca Cola, Wells Fargo, and American Express, where the prices were far from dirt cheap (as Graham would have wanted), but the long term returns were outstanding.</div><br /><div>In our world of Information Security, we start by aligning our priorities with the business using the thumbnail defense in depth approach, but then we would like to invest in high quality, effective controls.</div><br /><div>To get at the notion of control quality and effectiveness, I am going to start part 2 of this talk with a brief history of software. The first web software was just static HTML, but web software really got interesting when developers started creating dynamic websites using CGI an PERL.</div><br /><div>Once websites were hooked up to company databases and were not just serving static content, the security people realized they needed a security architecture, and they sprung into action. What they came up was was model that divided the world into &quot;good stuff&quot; which was comprised of all their networks, systems, and data; and then there was everything else the &quot;bad stuff&quot; on the Internet. So job one of the early days Internet security architecture was to separate all your good stuff (i.e. your network) for the bad stuff (the Internet). To do this the security people used a sophisticated tool called Visio to draw a flaming brick wall on the network diagram, and this flaming brick wall was supposed to keep the good stuff and the bad stuff separate.</div><br /><div>The security people also realized that the data and session tokens that they served up from their Web server would have to traverse the &quot;bad&quot; neighborhood called the Internet, so they added one more security mechanism to secure the last mile of the transaction - SSL between the browser and the Web server.</div><br /><div>And this was the state of the art security architecture used circa 1995 to protect the earliest dynamic web applications.</div><br /><div>What happened next was that the dotcom boom started to happen and businesses realized they could make some real money on the Web, the web apps started to get more sophisticated, more personalization, richer session experiences and so on. This led the Java people to create JSP and the Microsoft people to create ASP, and of course the PERL people to create even greasier PERL scripts, all of this in the effort to pooling resources and sessions on the Web server. The security people defended this new application programming model with network firewall and SSL.</div><br /><div>Around 1998, developers began building out more distributed N tier or 3 tier applications that separated the business logic layer, the presentation layer and the data access layer. Among other things, your web application could seamlessly integrate data from multiple back ends systems. Let&#39;s say you have pricing data in Oracle, order data in SAP, and customer data in a Mainframe. You write separate data access objects, apply business logic in the middle tier and then you tie it all together in a friendly user interface. At this point the web applications are beginning to integrate across departments and geographic boundaries, huge critical chunks of the business are now connected to the web. How did the security people defend this part of the business? They applied the same 1995 security architecture - network firewall and SSL.</div><br /><div>Around 1999-2000 timeframe businesses relied on web applications for major parts of the revenue, and the apps were built in different technologies like Java and Microsoft technologies, but the customer didn&#39;t care (still doesn&#39;t), the customer wanted (and still wants) data access and functionality. So to integrate the disparate technologies, SOAP and XML were deployed so that Microsoft could talk to Java and so Websphere could talk to Weblogic and so on. And, oh yes, SOAP and XML were used to connect B2B networks so partners in a supply chain and business process can exchange data and interoperate. &#0160;SOAP and XML present a fundamentally new programming model based on a message document style integration, where XML is used to mesh together data and functionality across platforms. SOAP and XML have no security model by default for authentication, authorization, and confidentiality. How did the security people deal with this? They kept the security architecture the same as they had in 1995 - network firewalls and SSL.</div><br /><div>The software world did not stop innovating in 2000 of course, in the last few years we have seen Web services and XML form the basis of baroque and powerful SOAs and simple REST applications. We have seen Web 2.0 come on the scene, and entirely new networked applications built on top of that.</div><br /><div>What we have not seen, is a single meaningful change in security architecture in 13 years. Developers have evolved, businesses have increasingly bet their entire business models on the web and they have increased security budgets. But what has the security architecture as its deployed in the field got to show for all of this? More firewalls and more SSL connections.</div><br /><div>Since Information Security has proven incapable of evolving, it is time to learn from a discipline that has mastered innovation - software development, and yes, I will step back in case the lightning bolts hits.</div><br /><div>What does software development focus on these days? Well, let&#39;s look at Service Oriented Architecture (SOA), all hype aside I look at SOA as a set of technologies that delivers three things:</div><br /><div>Virtualization: we want Beijing, Bangalore and Boston to communicate.</div><br /><div>Interoperability: we want our .Net stuff to talk to our java stuff.</div><br /><div>Reusability: how many order/claim/pricing/customer systems does one company need?</div><br /><div>To build out their SOA, developers separated the application interface from its implementation. So you can host the interface in a variety of locations, but its separate from the application logic and data.</div><br /><div>This is also a useful trick for putting services like SOAP through the firewall. SOAP was designed as a firewall friendly protocol. When SOAP first came out, Bruce Schneier said calling SOAP a firewall friendly protocol is like having a skull friendly bullet. Which is a great line and explains why his books fly off the shelves, it does not explain, why security people think an architecture designed in 1995 is the one we should be using today. Maybe the problem is not that the developers figured out how to go through the firewall to get the data their customers want, maybe the problem is that the firewall is the sum total of the security architecture, and it never adapted.</div><br /><div>A big part of this problem is that we have left Newton&#39;s world behind and entered Einstein&#39;s universe. Mainframes are Newton’s world, we have THE computer, THE price, THE record and so on.</div><br /><div>As Pat Helland explained [4,5], Mainframes are Newron&#39;s world, but Distributed computing is Einstein’s world. More specifically in the Einstein world of distributed computing - &quot;Computers don’t make decisions, computers try &#0160;to make decisions.&quot; Our computers don&#39;t really make a decision, they say you can buy this book from Amazon at this price, we have it in stock and will deliver on such and such a date. But the warehouse runs out, the pallet gets dropped in the warehouse, your boo is crushed, and the package is stolen off your front step. The computer confirmed your transaction, but the real world intervened.</div><br /><div>So we don&#39;t have iron clad decisions, instead its all about Memories (last time I checked your book was in stock), Guesses (we should be able to ship on this date) and Apologies (sorry the forklift ran over your book)</div><br /><div>Translating this into security, security mechanisms don’t make policy-based decisions, security mechanisms try to make policy-based decisions</div><br /><div>Some examples of memories, guesses and apologies in security</div><br /><div>Memories</div><div>Security Policies - for example Triple A policy</div><div>Triple A policies can memorize a map of subjects, objects, and roles. They can even replicate these memories and play them back at runtime to try to make policy enforcement decisions.</div><br /><div>Guesses</div><div>Security Policy Enforcement Decision</div><div>Unfortunately, while the policy enforcement decisions can be based on memorized logic, the decision itself is still a guess, even in the case of Triple A. Any guesses why? Because, the authentication process itself is a guess. It happens to be a guess that you then bind to a principal so it looks very official once you bind your guess to a Kerberos ticket or SAML assertion, but it still a guess.</div><br /><div>Apologies</div><div>Giant Global Bank is sorry your account was compromised!</div><div>And this leads to lots and lots of apologies by companies with poor access control models.</div><br /><div>Some additional examples of information security memories, guesses and apologies.</div><br /><div>Example Memories - Triple A Security Policies, Audit logs, User account information , Authorization Logic - concrete mapping Subject, Resource, Condition, Action</div><br /><div>Example Guesses - Security Policy Enforcement Decision Points, Authentication Logic, Monitoring, detection, fraud response</div><br /><div>Example Apologies - Identity Management tools - provisioning, deprovisioning, Reimburse customer for fraud losses, Compensating Transaction - Giant Global Bank is still sorry your account was compromised!</div><br /><div>The point of this is that security memories, guesses and apologies utilize different processes, different people, and different capabilities to be effective.</div><br /><div>What trends can we identify to lead us toward better qualitative analysis based on the best practices of virtualization, interoperability and reusability.</div><br /><div>Virtualization</div><div>Finding Vulnerabilities in a Virtualized World is a problem because applications are more configured than coded. Runtime behavior and structure not apparent due to weak typing and inversion of control.</div><br /><div>Result - finding bugs becomes harder.

The hard work in developing the index is developing a useful scale. A scale for XML tokens could use the following</div><br /><div>0: no token</div><div>1: hashed token</div><div>2: hashed and signed token</div><div>3: hashed and signed token from standard authoritative source</div><br /><div>An example scale for XML validation could use:</div><br /><div>0: no validation</div><div>1: schema validation</div><div>2: schema validation against hardened schema</div><div>3: schema validation against standard, hardened schema</div><br /><div>These indexed scales are used to show maturity across the factors in the scorecard. The first part of the talk described value, the value assessment is used to focus time and effort on high value assets. The value assessment can be determined quantitatively. There is hard analytical work to qualitatively determine the scorecard, index, and scales, the quantitative value assessment is used to screen out high value targets for these endeavors. The scoring index is used to track progress and improve quality over time. In the best case scenario, automated tools are used to perform the checks described in the index, and once security is automated just like software developers we may see security innovation make progress in years not decades.</div><br /><div>Thank you for your time.</div><br /><div>1 &quot;Risk Management is where the Money Is&quot; by Dan Geer,&#0160;<a href="http://catless.ncl.ac.uk/Risks/20.06.html">http://catless.ncl.ac.uk/Risks/20.06.html</a></div><br /><div>2 Berkshire Hathaway 2007 Shareholder Letter by Warren Buffett, <a href="http://www.berkshirehathaway.com/letters/2007ltr.pdf">http://www.berkshirehathaway.com/letters/2007ltr.pdf</a></div><br /><div>3 &quot;Software [In]security: Software Security Demand Rising, by Gary McGraw</div><div><a href="http://www.informit.com/articles/article.aspx?p=1237978">http://www.informit.com/articles/article.aspx?p=1237978</a></div><br /><div>4 &quot;SOA and Newton&#39;s Universe&quot; by Pat Helland, <a href="http://blogs.msdn.com/pathelland/archive/2007/05/20/soa-and-newton-s-universe.aspx">http://blogs.msdn.com/pathelland/archive/2007/05/20/soa-and-newton-s-universe.aspx</a></div><br /><div>5 &quot;Memories, Guesses and Apologies&quot; by Pat Helland, <a href="http://blogs.msdn.com/pathelland/archive/2007/05/15/memories-guesses-and-apologies.aspx">http://blogs.msdn.com/pathelland/archive/2007/05/15/memories-guesses-and-apologies.aspx</a></div><br /><div>6 &quot;Web Servicres Security Checklist&quot; by Gunnar Peterson, <a href="http://arctecgroup.net/pdf/WebServicesSecurityChecklist.pdf">http://arctecgroup.net/pdf/WebServicesSecurityChecklist.pdf</a></div>]]></content:encoded>

Am I? Maybe I Am!</a>&quot;), both related to Terry Child case, as well as a response to <a href="http://weblog.infoworld.com/venezia/archives/017945.html">this post</a>&#160; by Paul Venezia (<a href="http://weblog.infoworld.com/venezia/archives/017945.html">&quot;The anti-admin stance and the Childs case&quot;</a>).</p>  <p>First, let me disclose something - my frantic efforts with the Paint allow me to proudly proclaim: I am a certified, trusted &quot;Good Guy&quot;:</p>  <p><a href="http://lh3.ggpht.com/anton.chuvakin/SI-XiRAqh6I/AAAAAAAAExw/jPKKpXZ4XD8/s1600-h/certgoodguy2.png"><img style="border-top-width: 0px; border-left-width: 0px; border-bottom-width: 0px; border-right-width: 0px" height="172" alt="cert-good-guy" src="http://lh3.ggpht.com/anton.chuvakin/SI-Xi6AIgkI/AAAAAAAAEx0/l9EOLDTRH_s/certgoodguy_thumb.png?imgmax=800" width="244" border="0" /></a> </p>  <p>Good guys, let me tell you, do not need any controls placed on them; they are &quot;trusted.&quot; Don't you have to trust somebody? Why not trust a sysadmin, for example?</p>  <p>So, what about controls? Ah, glad that you asked! &quot;Controls&quot; are for the bad guys; they are in place to prevent the bad guys from doing &quot;an unspeakable evil&quot; (tm) :-) on you. On the other hand, good guys are doing &quot;the right thing&quot; every time - why monitor them? It goes without saying that nobody ever moves between these groups, especially, not from &quot;good guys&quot; to &quot;bad guys.&quot;</p>  <p>As I am rambling about this, many of my security-minded readers are wondering &quot;what is Anton up to? Isn't it kind of <strong>OBVIOUS</strong> that controls are for everybody?&quot; <strong>Controls know no good/bad!</strong> For example, a network control, say a NIPS, will block malicious web access due to a typo in a URL (by - gasp! - a good guy) or due to determined malicious hacking. </p>  <p>I think a few of my readers have watched <a href="http://www.imdb.com/title/tt0468569/">one too many &quot;Batman&quot; movies</a> and have acquired the dark side of the &quot;IT hero&quot; mentality.&quot; How about getting an &quot;IT employee&quot; mentality? If your boss is an idiot (and Terry's managers definitely seem pretty far gone in that direction...), than your &quot;heroic duty&quot; is to let them impale themselves on a sword of their idiocy, <em>not to commit crimes (even if cybercrimes) to prevent that idiocy</em>. Really, go find another job if you do not like the environment; good admins are needed in many places. For example, if your boss insists on <a href="http://www.theregister.co.uk/2008/07/28/sf_rogue_sysadmin_password_mess/">posting all VPN passwords for all users publicly</a> out of his sheer and unfathomable stupidity, it is your duty to tell him that it is &quot;a very bad idea&quot; - and not to change all passwords and not let him see it. &quot;Doing you job&quot; despite your boss and despite the law just doesn't work...</p>  <p><a href="http://chuvakin.blogspot.com/2008/07/on-doomsaying-terry-childs-case.html">In other words</a>, I want a banker making policy decisions at a bank, not a sysadmin. If a banker makes a wrong decision, his will suffer. If he is an idiot, he will most likely make the wrong decision. However, it is NOT the admin's decision to make - he does not &quot;own&quot; the business.&#160; BTW, the fact that it is a city, not a bank, and it is taxpayer funded, does not change it. </p>  <p>Am I &quot;anti-admin&quot; for <a href="http://chuvakin.blogspot.com/2008/07/on-doomsaying-terry-childs-case.html">saying</a> that admins should not run the business?&#160; Am I &quot;anti-admin&quot; for <a href="http://chuvakin.blogspot.com/2008/07/on-doomsaying-terry-childs-case.html">saying</a> controls (at least logging/auditing) on administrator activities are needed?&#160; <a href="http://weblog.infoworld.com/venezia/archives/017945.html">You</a> call it &quot;anti-admin&quot;, I call it <strong>common sense!!&#160; </strong>Pray tell me, what makes admins float above accountability, control and&#160; IT governance? </p>  <p>Please also <a href="http://www.ultimatewindowssecurity.com/blog/blog_commento.asp?blog_id=28&amp;month=07&amp;year=2008&amp;giorno=&amp;archivio=OK">read</a> what Randy Smith said about this issue; a lot of good thoughts that I agree with.</p>  <p>Now I would like to respond to specific comments from my readers:</p>  <blockquote>   <p> &quot;What rankles your readers is how blithely you imply this problem has a simple or effective solution. It doesn't, all the processes or tools you advocate can do is speed up the time it takes to detect the lock-out, but not actually prevent it - i.e. they are ineffective at tackling the primary problem.&quot;</p> </blockquote>  <p>That is correct; the rogue admin problem has NO simple solution. You might prevent some (few, really) things, you might log some of them and then figure what happened, but there is no simple solution (it goes without saying that &quot;just trust them&quot; is NOT a solution...)</p>  <blockquote>   <p>&quot;We all know companies run without sane risk management all the time and are rarely held accountable in America. What makes you think anyone is &quot;screwed&quot;?&quot;</p> </blockquote>  <p>Well, this is a good point; maybe I let my idealistic side take over. But, come on, just the fact that bad IT governance is somewhat common, doesn't make it right!</p>  <blockquote>   <p>&quot;Now ask yourself who is &quot;screwed&quot; by one person at a small company having all access and no accountability on a network. That's how I run my home network. Big deal.&quot;</p> </blockquote>  <p> Nobody is. I addressed it <a href="http://chuvakin.blogspot.com/2008/07/on-doomsaying-terry-childs-case.html">here</a>. The risk is acceptable for smaller environments, usually. I don't have an overseeing body set up to control my home passwords :-)</p>  <blockquote>   <p>&quot;You seem to forget that sometimes the management just has to trust somebody. &quot;</p> </blockquote>  <p>Addressed above.</p>  <blockquote>   <p>&quot;Chuvakin, you're a tool. Given the recent idiocy of the releasing of the VPN names and codes, it obviously shows that any sort of detest that Childs had against his superiors at the city were justified.&quot;</p> </blockquote>  <p>The fact that his bosses are idiots (which seems fairly well established!) does not make him right! </p>  <p><em>Bad boss + admin out of control =/= right :-)</em></p>  <blockquote>   <p>&quot;This is not a private organization. His superiors don't own the company and are NOT entitled to the data. We are, the taxpayers. And as a California taxpayer I fully support someone with the paranoia and technical skill of Terry Childs over a group of bureaucrats who release secure information to the public.&quot;</p> </blockquote>  <p>Properly evaluating this statement requires a law degree. Thus, no comment. Bureaucrats suck, but rogue admins are not a solution to that. Really!</p>  <blockquote>   <p>&quot;The guy was doing his job and doing it incredibly well, and keeping it out of the hands of those who, given their most recent choices, would bring potential disaster to the city.&quot;</p> </blockquote>  <p>He was NOT, unless crime is part of his job :-) Also, see comments on &quot;IT heroes&quot; above. If your boss is an idiot AND you don't like it, quit. </p>  <blockquote>   <p>&quot;<a href="http://chuvakin.blogspot.com/2008/07/on-doomsaying-terry-childs-case.html">Anton Chuvakin seems to think that all admins should be kept underneath management's boot at all times</a>. [...]&#160; Managers can't and don't understand what we do, and thus eventually come to the conclusion that we can't be trusted with our own knowledge. [...] Perhaps it's human nature to fear what you don't know or understand -- and that's why management can develop a fear of their own employees.&quot;</p> </blockquote>  <p>You say 'fear of employees', I say <strong>&quot;insider risk management.&quot;</strong> You say &quot;trust employees&quot;, I say <strong>&quot;trust but [be able to] verify (=log)&quot;</strong></p>  <blockquote>   <p>&quot;his blog leads the casual reader to infer that their businesses are in danger of being hijacked by disgruntled Sys Admins and that isn&#8217;t the case.&quot; (from <a href="http://www.teeple.tv/blog/?p=87">here</a>)</p> </blockquote>  <p>Eh, not all businesses, but some businesses - definitely (hmm, see Terry Childs story or other published insider attack cases, all the way back to <a href="http://www.usdoj.gov/criminal/cybercrime/lloydpr.htm">Omega Engineering case</a> and maybe all the way back to ancient history)</p>  <blockquote>&quot;I despise people like Terry Childs, but despise Chicken Little&#8217;s like Anton Chuvakin even more.&quot; (from <a href="http://www.teeple.tv/blog/?p=87">here</a>)</blockquote>  <p>You say&#160; I am 'chicken little', I say <strong>&quot;if your boss ignores <em>insider risk management</em>, he is stupid and deserves his business to fail.&quot;</strong>&#160; I also add <strong>&quot;if you think admins are 'above the law', you have a good chance of 'turning rogue' yourself AND then ending in jail.&quot;</strong></p>  <p>Finally, this and my other posts about the case are inspired by on the media reporting; I possess no &quot;insider knowledge&quot; on this case&#160; whatsoever.</p>  <p><strong>Possibly related posts:</strong></p>  <ul>   <li>&quot;<a href="http://chuvakin.blogspot.com/2008/07/on-doomsaying-terry-childs-case.html">On Doomsaying (Terry Childs case)</a>&quot; </li>    <li>&quot;<a href="http://chuvakin.blogspot.com/2008/07/on-doomsaying-terry-childs-case.html">So ...

<p>On the 28th episode of <em>The Silver Bullet Security Podcast</em>, Gary interviews Bill Cheswick, a lead member of technical staff at AT&#038;T Research and all around security guru.  Bill has been working in computer security for over 35 years.  He coined the term &#8220;proxy&#8221; in 1990 with reference to firewalls, and co-authored the book <em>Firewalls and Internet Security</em> which was used to train an entire generation of sys admins.  Gary and Bill discuss whether we&#8217;re winning or losing the computer security war, how security threats have evolved from pimply-faced teenagers to organized crime, whether we should move security into &#8220;the cloud,&#8221; and whether re-naming &#8220;Christmas lights&#8221; to &#8220;solstice lights&#8221; would bypass NJ holiday decoration ordinances.</p>

      <content:encoded><![CDATA[<p>Arnon cites his paper which builds on Deutsch, Gosling and Joy's famous Fallacies of Distributed Computing, specifically Fallacy #4 "the network is secure" These are common mistakes people make when building disiributed apps. Arnon <a href="http://www.rgoarchitects.com/nblog/2008/07/12/SOASecurityReminder.aspx">blogged</a> this:</p><br><div><span style="line-height: normal; "><blockquote><p> In my opinion, assuming the network is secure for an SOA is not only naïve but negligence pure and simple. The whole premise of moving an organization to SOA is connectedness and integration. So, unless your SOA will fail it will be connected to other systems. Whether you  are building RESTful systems, WS-* SOAs, EDAs or any combination of these architectural styles, If you won’t treat the services boundary as a border and secure it – you will be sorry…</p><p>Security in SOA should be considered at the "grand-scheme" level with issues like authertication, authorization but also at the single service level, looking at issues like DDOS, SQL injection, elevation of privilige and what not. A trivial thing like exposing a transaction beyond service boundaries can translate to an attacker denying services in your system simply by locking out your database. Again, this is just a simple example.</p><p>The other thing about Security is that you have to consider it early. patching security "later on" can have devestating effects on a system's capabilites esp. in areas related to performance. I have seen even military systems that had to go through serious rework, just  because Security was added as an afterthought instead of handled early on</p></blockquote>This is a great way to think about the problem, and as Arnon says its not just an issue with SOA security, its </span>a pervasive issue. If you think REST+SSL is a security architecture then you should consider what threats you are choosing *not* to deal with.</div><br><div>Also, Arnon articulated what I call the gateway vulnerability problem. SOA, Web services, REST et al are fundamentally gateway, interoperability focused technologies. And they are for the most part, great at providing simplified access to back end systems. The problem is that your mainframe, ERP, CRM, et al were never designed for anything remotely resembling an Internet threat model. So you just provided a gateway to a system that from a security standpoint is underpowered. The gateway is not the problem but what lies behind it.</div><br><div>In school they called marijuana a gateway drug because it led to heroin usage, in web services security if you put a Web service in front of your back end creating a vulnerable gateway to that which runs your business then your sys admin may wind doing heroin.</div>]]></content:encoded>

      <content:encoded><![CDATA[<p>Dennis Fisher blogs over at SearchSecurity.com about a <a href="http://security.blogs.techtarget.com/2008/06/10/critical-flaw-found-in-snmpv3/">new critical flaw found in SNMPv3</a>. I have blogged before how some NAC vendors that utilize SNMP have tried to fool unknowing sys admins that SNMP stands for security network management protocol, instead of simple NMP. <br><br>The SNMP zealots have always tried to counter the SNMP is not secure arguments by pointing to v3 as very security method and now this flaw is found. How many more will be found? In any event glad they found and fixed this. Now if they could just find someone using SNMPv3 it would be great!</p><blockquote></blockquote>
