			<content:encoded><![CDATA[<p>From Wired</p>
<div>
<p><a href="http://www.software.co.il/?attachment_id=70708" rel="attachment wp-att-70708"><img title="egypt7" src="http://www.wired.com/images_blogs/dangerroom/2012/01/egypt7.jpg" alt="" width="660" height="495" /></a></p>
<p>The revolt <a href="http://www.wired.com/dangerroom/2011/01/egypts-internet-shutdown-cant-stop-mass-protests/">that started a year ago</a> today in Egypt was spread by Twitter and YouTube, or so <a href="http://www.wired.com/dangerroom/2011/01/social-media-oppression/">the popular conception</a> goes. But a group of Navy-backed researchers has a more controversial thesis:Egyptians were infected by the idea of overthrowing their dictator.</p>
<p>Using epidemiological modeling to chart the discussions and their trajectory online is an interesting idea, I don&#8217;t think that they are the first ones to do it.  It&#8217;s a different approach to <a title="social network analysis" href="http://en.wikipedia.org/wiki/Social_network" target="_blank">social network analysis</a> which analyzes social phenomena through the properties of relations between and within units instead of the properties of these units themselves. This approach apparently considers trajectories of content combined with natural language analysis to determine what people in certain regions, of certain age groups, genders, or any number of other demographics, are discussing.</p>
<p>We&#8217;ve seen how content interception, classification and analysis has had success in the enterprise information security space &#8211; in particular with identifying data leaks by trusted insiders and unauthorized disclosure of intellectual property. Doing it on a national or global scale, is much more than computing power.  It&#8217;s also understanding the political milieu and intent of the subjects, a powerful challenge for any intelligence organization.</p>
<p>I&#8217;m not sure how they collect the actual demographics, handle historical data, deliberate disinformation or feedback effects or even if their model is a good fit for the problem but it&#8217;s thought provoking.</p>

			<content:encoded><![CDATA[<p>My daughter was distressed yesterday after the Feds shutdown the megaupload file sharing site &#8211; &#8220;How am I going to see all those series and Korean movies I love? It&#8217;s not fair!&#8221;</p>
<p>The FBI have been after Mr Dotcom for 8 years. His big problem was not the file sharing but his other criminal activities.  After all, there is infinite demand for file sharing,  <a title="virtual chop shops carry on" href="http://www.theregister.co.uk/2012/01/23/virtual_chop_shops_carry_on/" target="_blank">Filesonic is cleaning up now that Megaupload went bust</a> and Viacom didn&#8217;t go after Erich Schmidt as <a title="Youtube wins against Viacom" href="http://www.huffingtonpost.com/2010/06/23/youtube-viacom-lawsuit-se_n_623256.html" target="_blank">Viacom lost their billion dollar copyright case to Google</a> 2 years ago.</p>
<p>But really &#8211; beyond the consumer appetite for entertainment, and corporate appetite for filing intellectual property and copyright suites, why isn&#8217;t Hollywood getting it right when it comes to content protection?  If they <em><strong>were</strong></em> getting it right, Sony-Columbia would be running the file sharing sites, charging $1/movie and $3 for premium content and driving all the file sharing sites out of business.</p>
<p>Instead &#8211; the big studios are making the same mistake that corporate America makes when it comes to content protection &#8211; ignoring the attacker economics.</p>
<p>After all, the HDCP black-listing scheme defies the laws of physics and reason. For example, you may be a perfectly law-abiding citizen, but if someone in Sofia hacks your model XY500 DVD player, the device key is revoked, and you will <strong>never</strong> be able to play discs that came out after the date the device was compromised. If a hacker taps into the HDMI / HDCP signal copies a movie enroute to your model TV Set, the HDCP device key can be revoked and <strong>your 80 inch TV will never play high-definition again</strong>.</p>
<p>Blu-Ray copy protection was broken 5 years this month (January 2007) <a name="Blu-ray copy protection broken" href="http://www.theregister.co.uk/2007/01/23/blu-ray_drm_cracked/" target="blank"></a>(Courtesy of <em>muslix64</em>, the same fellow who cracked HD-DVD). Both HD DVD and Blu-ray use HDCP (High-Bandwidth Digital Content Protection) for authentication and content playing, and both use the AACS (Advanced Access Content System) for content encryption. (AACS is the content protection for the video on DVDs and HDCP is the content protection on the HDMI link between the DVD player and the TV). It appears that muslix64 took a snapshot in memory of a running process, then used selective keying – serially trying bytes 1-4, then 2-5, 3-6 etc as the keys until the MPEG frame decrypted. (much faster than a pure brute force attack). If the video player process stores the key in clear text in memory, this type of attack will always work.</p>
<p><strong>Like most flawed encryption schemes, AACS is vulnerable to threats to due a poor software implementation.</strong></p>
<blockquote><p>” The <a href="http://en.wikipedia.org/wiki/Advanced_Access_Content_System">AACS</a> design prevents legitimate purchasers from playing legitimately purchased content on legitimately purchased machines, and fails to prevent people from ripping the content and sharing it through bittorrent. The DRM people wanted something that could not be done, so unsurprisingly they winded up buying something that does not do it”</p>
<p>James Donald.</p></blockquote>
<p>Now we understand why BitTorrent is so popular and why</p>

			<content:encoded><![CDATA[<p><a href="http://www.software.co.il/wp-content/uploads/2012/01/OpenClinica_logo.gif"><img class="alignright size-full wp-image-4325" title="Open Clinica" src="http://www.software.co.il/wp-content/uploads/2012/01/OpenClinica_logo.gif" alt="" width="248" height="74" /></a>Ben Baumann from Akaza and Open Clinica fame, recently blogged about <a title="clinical trials in the cloud" href="http://blog.openclinica.com/2011/10/07/clinical-trials-cloud/" target="_blank">clinical trials in the cloud</a>.  Ben is pitching the relatively new offering from Akaza called Open Clinica Optimized hosting that offers quick startup using validated Open Clinica instances and resources on-demand on a SAS-70 compliant platform.</p>
<p>As Ben noted that in the clinical research field, putting together such an offering is not trivial. Open Clinica is the worlds fastest growing clinical trials software with an interesting Open Source business model of community-supported Open Source and revenue from enterprise licensing, cloud services and training.</p>
<p>Software Associates specializes in helping medical device vendors achieve HIPAA compliance and improve the data and software security of their products in hospital and mobile environments.  We have been working with a regulatory affairs consulting client for over 3 years now, using the Open Clinica application for managing  large multi-center, international clinical trials using Rackspace hosting and more recently using Rackspace Cloud.</p>
<p>I can attest that running multi-center clinical trails in the cloud is neither for the faint of heart nor weak of stomach.  Past the security, compliance and regulatory issues &#8211; there is also the issue of performance.</p>
<blockquote><p>Although resources are instantly scalable on-demand in the cloud, resources are not a substitute for secure software that runs fast.</p></blockquote>
<p>As I noted in a previous essay &#8220;<a title="application performance and cloud security" href="http://www.software.co.il/2011/06/the-connection-between-application-performance-and-security-in-the-cloud/" target="_blank">The connection between application performance and security in the cloud</a>&#8220;, slow applications require more hardware, more database replication, more load-balancing and more firewalls. <a title="More is not always better" href="http://www.software.co.il/?s=more+is+not+always+better" target="_blank">More is not always better</a>, and more layers of infrastructure increase the threat surface of the application with more attack points on the interfaces and more things that can go wrong during software updates and system maintenance.</p>
<p>If there is a design or implementation flaw in a cloud application for clinical trials management that results in the front-end Web server making 10,000 round trips to the back-end database server to render a matrix of 100 subjects, then throwing more hardware at the application will be a fruitless exercise.</p>
<p>If we do a threat analysis on the system, we can see that our No. 1 attacker is the software itself.</p>
<p>In that case, the application software designers have to go back to the drawing board and redesign the software and get that number down to 1 or 2 round trips.</p>
<p>The effort will be well worth it in your next bill from your cloud service provider.</p>

			<content:encoded><![CDATA[<p>From a recent article in <a title="Healthcare global - Anatonme" href="http://www.healthcareglobal.com/" target="_blank">Healthcare Global</a>.</p>
<p>Studies suggest that 30-50 percent of patients are likely to give up treatments early.  Microsoft Research has developed an innovative, hand-held medical device called <a title="Health care global anatonme" href="http://www.healthcareglobal.com/magazines/10115/page85" target="_blank">Anatonme</a> to help patients understand their issue and complete their treatment plan more often.</p>
<p>We&#8217;ve been doing research and development into private, controlled social networking to reinforce private communications between doctor and patient. It&#8217;s gratifying to see Microsoft Research doing work in this area.</p>
<p>Private social networking for doctors and patients provides highly effective secure data sharing between doctors and patients. It allows patient-mediated input of data before visits to the office, making the clinical data more accurate and complete and boosting the trust between doctor/healthcare worker and patient.</p>
<p>A private social network has a controlled 1 to N (doctor to patients) topology and physiological and emotional context, unlike Facebook that has a distracting social graph and entertainment context.</p>
<p>A private social network for doctors and patients also provides powerful information exchange and search:</p>
<ol>
<li>Capture critical events on a timeline (for example blood pressure, dizziness etc) that enables the doctor to respond in a timely fashion.</li>
<li>Reconciles differences between what the doctor ordered and what the patient did.</li>
<li>Granular access control for sharing of data between doctor, patient and referrals.</li>
</ol>

			<content:encoded><![CDATA[<p>In our experience, building a security portfolio on attack scenarios has 2 clear benefits;</p>
<ol>
<li>A robust, cost-effective security portfolio based on attack analysis  results in robust compliance over time.</li>
<li>Executives related well to the concepts of threat modeling / attack analysis. Competing, understanding the value of their assets, taking risks and protecting themselves from attackers is really, at the end of the day why executives get the big bucks.</li>
</ol>
<p>As I wrote in a previous essay &#8220;<a title="The valley of death between IT and security" href="http://www.software.co.il/2010/01/the-valley-of-death-between-it-and-information-security/">The valley of death between IT and security</a>&#8220;, there is a fundamental disconnect between IT operations (built on maintaining predictable business processes) and security operations (built on mitigating vulnerabilities).</p>
<p>Business executives delegate information systems to IT and information security to security people on the tacit assumption that they are the experts in information systems and security.  This is a necessary but not sufficient condition.</p>
<p>In the current environment of rapidly evolving types of attacks (hacktivisim, nation-state attacks, credit card attacks mounted by organized crime, script kiddies, competitors and malicious insiders and more&#8230;), it is essential that IT and security communicate effectively regarding the types of attacks that their organization may face and what is the potential business impact.</p>
<p>If you have any doubt about the importance of IT and security talking to each other, consider that leading up to 9/11, the CIA  had intelligence on Al Qaeda terrorists and the FBI investigated people taking flying lessons, but no one asked the question why Arabs were learning to fly planes but not land them.</p>
<p>With this fundamental disconnect between 2 key maintainers of information protection, it is no wonder that organizations are having difficulty effectively protecting their assets &#8211; whether Web site availability for an online business, PHI for a healthcare organization or intellectual property for an advanced technology firm.</p>
<p>IT and security  need a common language to execute their mission, and I submit that building the security portfolio around most<strong> likely threat scenarios</strong> from an attacker perspective is the best way to cross that valley of death.</p>
<p>There seems to be a tacit assumption with many executives that regulatory compliance is already a common language of security for an organization.  Compliance is a good thing as it drives organizations to take action on vulnerabilities but <strong>compliance checklists</strong> like PCI DSS 2.0, the HIPAA security rule, NIST 800 etc, are a dangerous replacement for thinking through the most likely threats to your business.  I have written about insecurity by compliance <a title="Insecurity by compliance" href="http://www.software.co.il/2012/01/insecurity-by-compliance/" target="_blank">here</a> and <a title="Monica Belluci and Security" href="http://www.software.co.il/2011/12/monica-belluci-and-security/" target="_blank">here</a>.</p>
<p>Let me illustrate why compliance control policies are not the common language we need.</p>
<p>PCI DSS 2.0 has an <em><strong>obsessive</strong></em> preoccupation with anti-virus.  It does not matter if you have a 16 quad-core Linux database server that is not attached the Internet with no removable device nor Windows connectivity. PCI DSS 2.0 wants you to install ClamAV and open the server up to the Internet for the daily anti-virus signature updates. This is an example of a compliance control policy that is not rooted in a probable threat scenario that creates additional vulnerabilities for the business.</p>
<p>Now, consider some <strong>deeper ramifications</strong> of compliance control policy-based security.</p>
<p>When a  QSA or HIPAA auditor records an encounter with a customer, he records the planning, penetration testing, controls, and follow-up, not under <em>a threat scenario</em>, but under a<em> control item</em> (like access control). The next auditor that reviews the  compliance posture of the business  needs to read about the planning, testing, controls, and follow-up and then reverse-engineer the process to arrive at which threats are exploiting which vulnerabilities.</p>
<p>Other actors such as government agencies (DHS for example) and security researchers go through the same process. They all have their own methods of churning through the planning, test results, controls, and follow-up, to reverse-engineer the data in order to arrive at which threats are exploiting which vulnerabilities.</p>
<p>This ongoing process of “reverse-engineering” is the root cause for a series of additional problems:</p>
<ul>
<li>Lack of overview of the the security threats and vulnerabilities that really count</li>
<li>No sufficient connection to best practice security controls, no indication on which controls to follow or which have been followed</li>
<li>No connection between controls and security events, except circumstantial</li>
<li>No ability to detect and warn for negative interactions between countermeasures (for example &#8211; configuring a firewall that blocks Internet access but also blocks operating system updates and enables malicious insiders or outsiders to back-door into the systems from inside the network and compromise  firewalled services).</li>
<li>No archiving or demoting of less important and solved threat scenarios (since the data models are control based)</li>
<li>Lack of overview of security status of a particular business, only a series of historical observations disclosed or not disclosed.  Is Bank of America getting better at data security or worse?</li>
<li>An excess of event data that cannot possibly be read by the security and risk analyst at every encounter</li>
<li>Confidentiality and privacy borders are hard to define since the border definitions are networks, systems and applications not confidentiality and privacy.</li>
</ul>
<h3>Threat scenarios as an alternative to compliance control policies</h3>
<p>When we perform a software security assessment of a medical device or healthcare system, we think in terms of &#8220;threat scenarios&#8221; or &#8220;attack scenarios&#8221;, and the result of that thinking manifests itself in planning, penetration testing, security countermeasures, and follow-up for compliance. The threat scenarios are not &#8220;one size fits all&#8221;.  The threat scenarios for an AIDS testing lab using medical devices that automatically scan and analyze blood samples, or an Army hospital using a networked brain scanning device to diagnose soldiers with head injuries, or an implanted cardiac device with mobile connectivity are all totally different.</p>
<p>We evaluate the medical device or healthcare product from an attacker point of view, then from the management team point of view, and then recommend specific cost-effective, security countermeasures to mitigate the damage from the most likely attacks.</p>
<p>Threat scenarios consider asset values, vulnerabilities, threats and possible security countermeasures. Threat analysis as a methodology does not look for ROI or ROSI (there is no ROI for security anyhow) but considers the best and cheapest way to reduce asset <a title="VaR risk management" href="http://en.wikipedia.org/wiki/Value_at_risk#VaR_risk_management" target="_blank">value at risk</a>.</p>
<p>In our experience, building the security portfolio on threat scenarios has 2 clear benefits;</p>
<ol>
<li>A robust, cost-effective security portfolio based on attack analysis  results in robust compliance over time.</li>
<li>Executives relate well to the concepts of threat modeling / attack analysis. Competing, understanding the value of their assets, taking risks and protecting themselves from attackers is really, at the end of the day why executives get the big bucks.</li>
</ol>

			<content:encoded><![CDATA[<h3 align="JUSTIFY">Beyond the firewall &#8211; data loss prevention</h3>
<p align="JUSTIFY">What a simple idea. It doesn&#8217;t matter how they break into your network or servers &#8211; if attackers can&#8217;t take out your data, then you&#8217;ve mitigated the threat.</p>
<p align="JUSTIFY">Data loss prevention is a category of information security products that has matured from Web / email content filtering products into technologies that can detect unauthorized network transfer of valuable digital assets such as credit cards. This paper reviews the motivation for and the taxonomies of advanced content flow monitoring technologies that are being used to audit network activity and protect data <em>inside </em>the network.</p>
<h3 align="JUSTIFY">Motivation &#8211; why prevent data loss?</h3>
<p align="JUSTIFY">The majority of hacker attacks and data loss events are not on the IT infrastructure but on the <strong>data</strong> itself.  If you have valuable data (credit cards, customer lists, ePHI) then you have to protect it.</p>
<p align="JUSTIFY">Content monitoring has traditionally meant monitoring of employee or student surfing and filtering out objective content such as violence, pornography and drugs. This sort of Web content filtering became “mainstream” with wide-scale deployments in schools and larger businesses by commercial closed source companies such as McAfee and Bluecoat and Open Source products such as Censor Net and Spam Assassin. Similar signature-based technologies are also used to perform intrusion detection and prevention.</p>
<p align="JUSTIFY">However, starting in 2003, a new class of content monitoring products started emerging that is aimed squarely at protecting firms from unauthorized “information leakage”, “data theft” or “data loss” no matter what kind of attack was mounted. Whether the data was stolen by hackers, leaked by malicious insiders or disclosed via a Web application vulnerability, the data is flowing out of the organization. The attack vector in a data loss event is immaterial if we focus on preventing the data loss itself.</p>
<p align="JUSTIFY">The motivation for using data loss prevention products is <strong>economic</strong> not <strong>behavioral</strong>; transfer of digital assets  such as credit cards and PHI by trusted insiders or trusted systems can cause much more economic damage than viruses to a business.</p>
<blockquote>
<p align="JUSTIFY">Unlike viruses, once a competitor steals data you cannot reformat the hard disk and restore from backup.</p>
</blockquote>
<p align="JUSTIFY">Companies often hesitate from publicly reporting data loss events because it damages their corporate brand, gives competitors an advantage and undermines customer trust no matter how much economic damage was actually done.</p>
<h3 align="JUSTIFY">Who buys DLP (data loss prevention)?</h3>
<p align="JUSTIFY">This is an interesting question. On one hand, we understand that protecting intellectual property, commercial assets and compliance-regulated data like ePHI and credit cards is  essentially an issue of  business risk management. On the other hand, companies like Symantec and McAfee and IBM sell security products to IT and information security managers.</p>
<p align="JUSTIFY">IT managers focus on maintaining predictable execution of business processes not dealing with unpredictable, rare, high-impact events like data loss.  Information security managers find DLP technology interesting (and even titillating &#8211; since it detects details of employee behavior, good and bad) but an  information security manager who buys Data loss prevention (DLP) technology is essentially admitting that his perimeter security (firewall, IPS) and policies and procedures are inadequate.</p>
<p align="JUSTIFY">While data loss prevention may be a problematic sale for IT and information security staffers, it plays well into the overall risk analysis,  risk management and compliance processes of the business unit.</p>
<h3 align="JUSTIFY">Data loss prevention for senior executives</h3>
<p align="JUSTIFY">There seem to be three schools of thought on this with senior executives:</p>
<ol>
<li>One common approach is to <em><strong>ignore the problem</strong></em> and brush it under the compliance carpet using a line of reasoning that says &#8220;If I&#8217;m PCI DSS/HIPAA compliant, then I&#8217;ve done what needs to be done, and there is no point spending more money on fancy security technologies that will expose even more vulnerabilities&#8221;.</li>
<li>A second approach is to perform <em><strong>passive data loss detection and monitor flow of data</strong></em>(like email and file transfers) without notifying employees or the whole world. Anomalous detection events can then be used to improve business processes and mitigate system vulnerabilities. The advantage of passive monitoring is that neither employees nor hackers can detect a Layer 2 sniffer device and a sniffer is immune to configuration and operational problems in the network. If it can’t be detected on the network. then this school of thought has plausible deniability.
<div></div>
</li>
<li>A third approach takes data loss prevention a step beyond security and turns it into a competitive advantage. A smart CEO can use data loss prevention system as a deterrent <em><strong>and</strong></em> as a way of enhancing the brand (“your credit cards are safer with us because even if the Saudi hacker gets past our firewall and into the network, he won&#8217;t be able to take the data out”).</li>
</ol>
<h3 align="JUSTIFY">A firewall is not enough</h3>
<p align="JUSTIFY"><span style="font-family: TimesNewRomanPSMT, 'Times New Roman', serif;">Many firms now realize that a firewall is not enough to protect digital assets </span><span style="font-family: TimesNewRomanPSMT, 'Times New Roman', serif;"><em>inside</em></span><span style="font-family: TimesNewRomanPSMT, 'Times New Roman', serif;"> the network and look towards incoming/outgoing content monitoring. This is because: </span></p>
<ol>
<li>
<p align="JUSTIFY"><span style="font-family: TimesNewRomanPSMT, 'Times New Roman', serif;">The firewall might not be properly configured to stop all the suspicious traffic.</span></p>
</li>
<li>
<p align="JUSTIFY"><span style="font-family: TimesNewRomanPSMT, 'Times New Roman', serif;">The firewall doesn’t have the capability to detect all types of content, especially embedded content in tunneled protocols.</span></p>
</li>
<li>
<p align="JUSTIFY"><span style="font-family: TimesNewRomanPSMT, 'Times New Roman', serif;">The major of hacker attacks and data loss events are not on the IT infrastructure but on the data itself.</span></p>
</li>
<li>
<p align="JUSTIFY"><span style="font-family: TimesNewRomanPSMT, 'Times New Roman', serif;">Most hackers do not expect creative defenses so they assume that once they are in, nobody is watching their nasty activities.</span></p>
</li>
<li>
<p align="JUSTIFY"><span style="font-family: TimesNewRomanPSMT, 'Times New Roman', serif;">The firewall itself can be compromised. As we have more and more Day-0 attacks and trusted insider threats, so it is good practice to add additional independent controls.</span></p>
</li>
</ol>
<h3 align="JUSTIFY">Detection</h3>
<p>Sophisticated incoming and outgoing (data loss prevention or DLP) content monitoring technologies basically use three paradigms for detecting security events</p>
<ol>
<li>AD- Anomaly Detection &#8211; describes normal network behavior and flags everything else</li>
<li>MD- Misuse Detection &#8211; describes attacks and flags them directly</li>
<li>BA &#8211; Burglar alarm – describes abnormal network behavior (“detection by exception”)</li>
</ol>
<p>In anomaly detection, new traffic that doesn’t match the model is labeled as suspicious or bad and an alert is generated. The main limitation of anomaly detection is that if it is too conservative, then it will generate too many false positives (a false alarm) and over time the analyst will ignore it. On the other hand, if a tool rapidly adapts the model to evolving traffic change, then too little alerts will be generated and the analyst will again ignore it.</p>
<p>Misuse detection describes attacks and flags them directly, using a database of known attack signatures and constantly tries to match the actual traffic against the database. If there is a match, an alert is generated. The database typically contains rules for:</p>
<ol>
<li>Protocol Stack Verification – RFC’s, ping of death, stealth scanning etc.</li>
<li>Application Protocol Verification – WinNuke , invalid packets that cause DNS cache corruption etc.</li>
<li>Application Misuse – misuse that causes applications to crash or enables a user to gain super user privileges; typically due to buffer overflows or due to implementation bugs.</li>
<li>Intruder detection. Known attacks can be recognized by the effects caused by the attack itself. For example, Back Orifice 2000 sends traffic on default port is 31337</li>
<li>Data loss detection – for example by file types, compound regular expressions, linguistic and/or statistical content profiling. Data loss prevention or detection needs to work at a much higher level than intrusion detection – since it needs to understand file formats and analyze the actual content such as Microsoft Office attachments in a Web mail session as opposed to doing simple pattern matching of an http request string.</li>
</ol>
<p>Using a burglar alarm model, the analyst needs deep understanding of the network and what should not happen with it. He builds rules that model how the monitored network should conceptually work, in order to generate alerts when suspicious traffic is detected. The richer the rules database, the more effective the tool. The advantage of the burglar alarm model is that a good network administrator can leverage his knowledge of servers, segments and clients (for example a Siebel CRM server which is a client to a Oracle database server) in order to focus-in and manage-by-exception.</p>
<h4>What about prevention?</h4>
<p>Anomaly detection is an excellent way of identifying network vulnerabilities but a customer cannot prevent extrusion events based on general network anomalies such as usage of anonymous ftp. In comparison there is a conceptual problem with misuse detection. If misuse is detected then unless the event can be prevented (either internally with a TCP reset, by notifying the router or firewall) – then the usefulness of the devices is limited to forensics collection.</p>
<h4>What about security management?</h4>
<p>SIM – or security information management consolidates reporting, analysis, event management and log analysis. There are a number of tools in this category – Netforensics is one. SIM systems do not perform detection or prevention functions – they manage and receive reports from other systems. Checkpoint for example is a vendor that provides this functionality with partnerships.</p>
<h3>Summary</h3>
<p>There are many novel DLP/data loss prevention products, most provide capabilities far ahead of both business and IT infrastructure management that are only now beginning to look towards content monitoring behind the firewall.</p>
<p>DLP (Data loss prevention) solutions join an array of content and application-security products around the traditional firewall. Customers are already implementing a multitude of network security products for Inbound Web filtering, Anti-virus, Inbound mail filtering and Instant Messaging enforcement along with products for SIM and integrated log analysis.</p>
<p>The industry has reached the point where the need to simplify and reduce IT security implementation and operational costs becomes a major purchasing driver, perhaps more dominant than any single best-of-breed product.</p>
<p>Perhaps data loss prevention needs to become a network security function that is part of the network switching fabric; providing unified network channel and content security.</p>
<p>Software Associates helps healthcare customers design and implement such a unified network channel and enterprise content security solution today enabling customers to easily define policies such as “No Instant Messaging on our network” or “Prevent patient data leaving the company over any channel that is not an authorized SSH client/server”.</p>

			<content:encoded><![CDATA[<p>A recent article on CSO online ponders the question of <a title="are passwords dead" href="http://www.csoonline.com/article/697667/passwords-aren-t-dead-though-maybe-yours-should-be" target="_blank">whether or not passwords are dead</a> &#8211; since they are not much of a security countermeasure anyhow (or so the article intimates). The article quotes a person who seems to believe that SQL injection attacks have to do with password security.</p>
<blockquote><p>Christopher Frenz, CTO at See-Thru and a faculty member at Mercy College, both in New York, says the problem is, &#8220;not because of passwords being obsolete, but because of the prevalence of bad passwords and bad password practices.&#8221;</p>
<p>He points to the 2009 SQL injection attack on the social media site RockYou that compromised 32 million user account passwords. &#8220;The only password security requirement was a password of at least five characters,&#8221; he says, &#8220;(which) resulted in people choosing passwords such as <a href="http://blogs.csoonline.com/1294/gawker_fallout_mel_brooks_warned_us">12345</a>, Password, rockyou, and abc123,&#8221; plus common dictionary words.</p>
<p>Besides that, the passwords were stored in plain text format, along with users&#8217; email addresses.</p>
<p>Frenz says some websites (Hotmail recently among them) now require more complex passwords with multiple character types.</p></blockquote>
<p>I&#8217;m speechless.</p>
<p>SQL injection attacks on Web sites are made possible because of poor coding practices that take input strings from forms or query strings and concatenate with SQL snippets like this:</p>
<blockquote><p>2&#8242;;Update tbl_accountParent set Email=<a href="mailto:Email%2B%27%3Bamit.kinor@gmail.com" target="_blank">Email+&#8217;;</a>obama@whitehouse.giv&#8217;;select * from  tbl_accountParent where &#8217;1&#8242;=&#8217;1</p></blockquote>
<p>From now on, whenever any user asks for password reminder, Mr. Obama will get a nice email with his user name and password.</p>
<p>And frankly, I don&#8217;t understand programmers or Web site operators who tolerate storing passwords in plain text or encrypting them instead of using one-way hashes</p>
<p>Maybe a bunch of people should read the <a title="Cryptography" href="http://cr.yp.to/crypto.html" target="_blank">online introduction to cryptography</a> by Dan Bernstein.</p>

			<content:encoded><![CDATA[<p>Do you run an e-commerce site?</p>
<p>Are you <em><strong>sure</strong></em> you do not store any payment card data or PII (personally identifiable information) in some MySQL database?</p>
<p>The first step in protecting credit card and customer data is to know what sensitive data you <em><strong>really</strong></em> store, classify what you have  and set up the appropriate security controls.</p>
<p>Here is a policy for any merchant or payment processor who want to achieve and sustain PCI DSS 2.0 compliance and protect customer data.</p>
<h2>I. Introduction</h2>
<p>You need to identify and apply controls to the data types identified in this policy. The data types identified below are considered digital assets and are to be controlled and managed as specified in this policy while retained or processed by the organization. You should identify and inventory all systems that store or process this information and will audit these systems on a semi-annual bases for effectiveness of controls to manage the data types.</p>
<h2>II. Background</h2>
<p>The Payment Card Industry (PCI) Security Standard is a requirement for all financial institutions and merchants that use or process credit card information. This security standard is designed to help protect the integrity of the credit card systems and to help mitigate the risk of fraud and identity theft to the individuals who use credit cards to make purchases for goods and services.</p>
<p>The PCI Security Standard was originally introduced by by VISA as the Cardholder Information Security Program (CISP) and specified the security controls for each level or merchant and credit card processor. In 2004 the major brands in the card payment industry agreed to adopt the CISP standard and requirements and a single industry standard in order to reduce the costs of implementation and assessment and increase the rate of adoption. Most organizations were required to meet all requirements of the PCI security standard by June 30<sup>th</sup> 2005 and it is now an ongoing compliance process with merchants, payment processors and issuers.</p>
<h2>III. General Policy Statement</h2>
<p>All Credit Card Information and associated data is company confidential and will not be transmitted over public networks in the clear. Credit Card information can only be transmitted encrypted and only for authorized business purposes to authorized parties that have been approved to receive credit card information.</p>
<p><span id="more-4283"></span></p>
<h2>IV. Data Classifications of Credit Card Information</h2>
<h2>Personally Identifiable Information</h2>
<h3><a name="OLE_LINK1"></a><a name="OLE_LINK2"></a>Data Description and Policy</h3>
<p>Any information that is collected about the owner of the credit card such as their name, signature, address, phone number or driver’s license number or social security number will be classified and controlled as PERSONALLY IDENTIFIABLE INFORMATION or PII. As a general rule to help the user identify PII data consider if a reasonable person with a reasonable level of effort could use the information to identify an individual. PII data is confidential to the organization and can only by used for specific purposes which are listed below. Only pre-authorized parties are allowed to receive PII data and only through authorized communication channels.</p>
<h3>Examples</h3>
<p>The following examples are for illustration only and do not necessarily comprise a complete set of all types of Personally Identifiable Information:</p>

			<content:encoded><![CDATA[<p>My friend <a href="http://nrkonline.wordpress.com/">Nissan Ratzlav-Katz</a> starting blogging about customer service in Israel and how tolerant many of us have become to sub-standard and even really crappy customer service.</p>
<p>An objection I&#8217;ve heard frequently to Google Apps is that they don&#8217;t give customer service &#8211; although I would argue that great products delivered that work on a global scale for free definitely qualify as great customer service.</p>
<p><a href="http://uk.techcrunch.com/2009/08/13/how-do-startups-make-customer-service-scale-into-awesomeness/">How do startups make customer service scale into awesomeness?</a> touches on many good points including a I Love/I Hate Ratio (Virgin Atlantic scores at the bottom &#8211; Microsoft is about even and Amazon, Google score at around 8 &#8211; meaning that 8x as many people love Google as hate them. Which is pretty impressive I thought.</p>
<p>Still &#8211; one thing we miss is the synergy between love/hate and suppliers and customers. If you give great service, customers will love you and if you&#8217;re a great customer and pay on time &#8211; suppliers will love you.</p>
<p>The only counter-example I know is Israeli corporate customers that will pay the best supplier in the world Net 180 days and take a 20% discount just because they felt like it.</p>
<p>Bottom line &#8211; Israel may be a country with a poor service ethic but it&#8217;s also a country with a poor payment on time ethic and poor data security, customer privacy ethic</p>
<p>In my book &#8211; not an accident.  If you treat your customers and suppliers well, you will tend to treat the issues of data security and customer privacy accordingly.</p>
