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.
