levels. Admins can run certain tests, groups or whole security levels.
The library and the tools are implemented in python and tests are
sectool-gui provides a GTK-based graphical user interface to sectool.
RATS scans through code, finding potentially dangerous function calls.
The goal of this tool is not to definitively find bugs (yet). The
current goal is to provide a reasonable starting point for performing
manual security audits.
The initial vulnerability database is taken directly from things that could be easily found when starting with the forthcoming book, “Building Secure Software” by Viega and McGraw.
TIGER, or the “tiger” scripts, is a set of Bourne shell scripts,
C programs and data files which are used to perform a security audit
of UNIX systems. It is designed to hopefully be easy to use, easy to
