SCARE (Source Code Analysis Risk Evaluation) analyzes source code and provides a realistic and factual representation of the potential of that source code to create a problematic binary. This metric will not say that the binary will be exploited, nor does it do a static analysis for known limitations like vulnerabilities. However, it will flag code for a particular interaction type or control and allow the developer to understand which operational security (OpSec) holes are not protected even if it can't say the effectiveness of that protection at this time.
Patchman is a patch status monitoring tool for Linux systems. Patchman clients send a list of installed packages and enabled repositories to the server. The server (CLI or Web) tells the user which hosts require updates, whether those updates are normal or security updates, and shows installed packages that are not part of any repository. Hosts, packages, repositories. and operating systems can be filtered using features or arbitrary tags. For example, you can find out which hosts have a certain version of a package installed, and which repository it comes from. Patchman does not (yet) have the ability to update packages on hosts.
SecQua is a tool that quantifies the security of a given Information System, using a novel security metric. It tries to provide a deterministic, unbiased, objective, and efficient measurement. The approach is vulnerability driven and uses the National Vulnerability Database. A security metric must answer questions such as "How secure am I?", "Am I better compared to my last checkpoint/year?", "Am I spending the right amount of money for security?", "How do I compare to my peers?", and "What risk transfer options do I have?". SecQua can state that a system is now 60.2% secure, when last month it was 46.5%. Moreover, it tries to depict how vulnerability patterns expose the information system over time.
debcheckroot is a tool that retrieves file checksums online or from read only media. It provides trusted verification of your root file system at least as far as you can trust your Internet connection or your verification medium (DVD, BD, etc.). Unlike debsums, it doesn't rely on locally stored md5sums which can be modified by an attacker along with the files themselves. It also provides cleaner and better structured output, and can spot files added to your system by someone else.
LPVS (Linux Package Vulnerability Scanner) is a Linux distribution news feed based package version scanner that shows which security advisories apply to your system, which packages are installed in a vulnerable version, and to which versions you should upgrade. Currently supported distributions: Ubuntu and CentOS.
