data privacy automation Every system admin has lived through the same Monday morning ritual. A queue of forty tickets, half of them password resets, permission errors, or disk space warnings that any experienced technician could resolve in under two minutes. The other half require actual judgment. For years, automation promised that software would eventually sort the two apart on its own. That promise is now being tested in production Linux environments. . Early results are reshaping how IT teams think about tier-1...

software developmentsecurity best practicessoftware flawsBest Practices For Securing Software Development Lifecycle
Just as software is everywhere, flaws in most of that software are everywhere too. Flaws in software can threaten the security and safety of the very systems on which they operate. The best way to prevent such vulnerabilities in software is to proactively incorporate security and other non-functional requirements into all phases of Software Development Lifecycle (SDLC).. Drawing on the best practices from our book Secure and Resilient Software Development this article summarizes some key activities required for integrating security into your SDLC and offers some recommendations and advice for implementing your own secure software development program.

security threatsprogramming errorsIT securityTop 25 Programming Errors Impacting IT Security According to SANS
When it comes to programming errors, some are more common than others. A new report from the SANS Institute identifies the top 25 programming errors that have led to nearly every type of IT security threat over the last year. The report draws on the input of 28 different groups including those in government and the private sector and leverages the CWE (Common Weakness Enumeration) numbering system to label vulnerabilities.. The report follows one done by SANS on the same topic for 2009, and provides similar findings this time around. But while the SANS lists attempt to identify the top programming errors, there is some disagreement when it comes to the top programming errors that Linux developers face. "The takeaway from this list isn't so much that there is anything here that is particularly new or surprising at all," Alex Horan, director of product management at Core Security, said in a e-mail to InternetNews.com. "In fact, what it reinforces is that most organizations, and software/Web app developers, continue to struggle with the same types of security issues that they've been dealing with for years." The 2010 SANS list is structured differently than the 2009 list which provided the top 25 in a list broken down by three categories. For 2010, SANS has also provided a general ranking of the top 25 with Cross Site Scripting (XSS) The link for this article located at CodeGuru is no longer available. .

This is an excellent lesson in the security problems inherent in trusting proprietary software: After two years of attempting to get the computer based source code for the Alcotest 7110 MKIII-C, defense counsel in State v. Chun were successful in obtaining the code, and had it analyzed by Base One Technologies, Inc.

security practicescybercrimesecurity analysisInvestigating Software Flaws in Forensics: Insights from DefCon
Those of you familiar with CSI (or have surely heard of it) are all too familiar with the process they use to catch the criminals - scientific analysis, forensics, gadgetry, and smarmy head investigators. Reoccurring themes include DNA analysis or other types of human-related evidence. However, in the information world, catching a criminal after the crime is in another league of its own. This article presents an account of a recent DefCon presentation which focused on breaking the actual forensics software used to analyze compromised systems. The most interesting line in the article referred to the weaknesses in one of the most popular forensics tools - "Most of these can and will be fixed in the near future, but at least one is a design flaw, not a bug.". Read on to find out how your forensics tools are only as good as the makers of them, and how it can result in a perfect getaway. .

security researchsoftware flawsbug bountyExploring the Rise of Bug Bounties and Vulnerability Sales in Security
The co-founder of security group Secure Network Operations Software (SNOSoft), Desautels has claimed to have brokered a number of deals between researchers and private firms--as well as the odd government agency--for information on critical flaws in software. Last week, he bluntly told members of SecurityFocus's BugTraq mailing list and the Full-Disclosure mailing list that he could sell significant flaw research, in many cases, for more than $75,000. "I've seen these exploits sell for as much as $120,000," Desautels told SecurityFocus in an online interview. It's a statement that underscores the increasing acceptance of the sale of vulnerability information. Once a frowned-upon practice, the sale of such information is taking off. Flaw bounty programs such as TippingPoint's Zero-Day Initiative (ZDI) and iDefense's Vulnerability Contributor Program (VCP) have added legitimacy to the practice, even if they remain controversial. Software vendors have had to increasingly get used to dealing with third parties reporting security flaws that were bought from anonymous researchers. Microsoft, for example, patched at least 17 flaws reported by the two programs in 2006, up from 11 reported in 2005. . Desautels, now the chief technology officer for boutique security firm Netragard, highlighted the trend by announcing a program on Wednesday whereby the security company would act as a broker to any researcher with a critical flaw to sell. The program could be a more lucrative option for freelance researchers aiming to sell information on software vulnerabilities. In many ways, the push by researchers for greater returns on their research efforts is part of the ebb and flow of the debate over the proper way to disclose information about software vulnerabilities. In 2000, a researcher known as Rain Forest Puppy released a basic framework, dubbed the RFPolicy, for disclosing vulnerabilities in a way that seemed fair to responsible software makers. In 2002, two security researchers further refined the guidelinesand submitted them to the Internet Engineering Task Force (IETF), but the technical standards body decided that setting disclosure policy was outside of its jurisdiction. Over the past few years, software makers, and Microsoft in particular, have focused on holding researchers to the guidelines, calling such disclosure "responsible." It's been an uneasy truce, and one that has fractured in many places. In 2005, a researcher attempted to auction off information about a flaw in Microsoft Office. Other flaw finders have decided to just release details of vulnerabilities they have found as a punishment for, what they believe to be, irresponsible behavior on the part of the software vendor. In the last six months, for example, a number of researchers have collected advisories on potential security issues into month-long releases of daily bugs. The trend started with the Month of Browser Bugs in July and continues with the latest Month of Apple Bugs this month. Now, flaw finders fed up with software vendors are increasingly turning to third parties to buy their research. "One of the reasons why the hacking community is so frustrated with large corporations is because these corporations are making a killing off their research and they are not seeing fair value for their work," Desautels said in an online interview with SecurityFocus. Software makers typically do not pay for vulnerability information, with the notable exception of the Mozilla Foundation. The well-known public bounty programs typically pay thousands of dollars for original vulnerabilities, while lesser-known private deals can net a researcher tens of thousands of dollars, according to security experts. The amounts quoted by Desautels are not excessive, according to experts interviewed by SecurityFocus. In September, for example, a private buyer approached noted security researcher HD Moore and offered between $60,000 and $120,000 for each client side vulnerability found in Internet Explorer, the founder of the Metasploit Projectsaid. Moore declined to pursue the offer, but said that such prices are typical of high-level private purchases, while information on serious flaws in generic enterprise-level applications can be sold to safe buyers--such as 3Com's ZDI program and VeriSign's VCP program--for between $5,000 and $10,000. "The ZDI and (VCP) programs are definitely the easier way to sell a vulnerability, but at the 5x or 10x multipliers you see from a private buyer, it's usually worth the effort," Moore told SecurityFocus in an e-mail interview The link for this article located at Security Focus is no longer available. .
