Why this tool?

The Tiger tool is used to scan your system and perform a security audit. Tiger checks configuration files and the system state. Based on the findings it will show suggestions to improve the security level of the system.

The Tiger project also states on their project page it can be used as an intrusion detection tool. This promise is somewhat outdated. To be effective in the area of intrusion detection, its technology needs to be kept up-to-date. Still, the tool might find traces that give away a system breach.

How it works

The engine of Tiger is based on small scripts that do individual checks. A typical example of such check is to look for a configuration file and see if its settings are in a preferred state.

Like other tools in this category, Tiger is light on resources. It uses shell script as its core and leverages common system utilities to do the work.
