Buck-Security is a security scanner for Debian and Ubuntu Linux. It helps you to harden your system by running some important security checks. For example, it finds world-writable files and directories, setuid and setgid programs, superuser accounts, and installed attack tool packages. It also checks your umask and checks if the sticky bit is set for /tmp, among other checks.
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.
