SID-IDS

SID-IDS is a noteworthy host intrusion detection system that offers features like Shell/PTY Intrusion Detection, which aims at detecting unwanted PTY action on UNIX systems. This Host Intrusion Detection System comprises of a kernel part and a user part that collaboratively detect and analyze the behavior of the system. The kernel part effectively plugs into the terminal processing subsystem of the system and logs hashed terminal lines, whereas the user part reads those log entries (hashes) and takes appropriate action when finding unexpected log entries.

What sets this software apart is its compatibility with systems like Solaris SPARC, i386, Linux 2.4 and x86 Linux 2.6. However, users must note that the kernel part for both Solaris and Linux 2.4 haven't changed since release 0.3.7. The software comes with Debian Linux packages for i386 and a build script to create your own binary Debian packages. It also includes Solaris 8 i386 and SPARC packages and a build script to create your own Solaris binary packages.

All in all, SID-IDS is a reliable and efficient host intrusion detection system that serves its purpose well. Its compatibility with a wide range of systems and easy-to-use build scripts make it an excellent choice for businesses and organizations looking for a robust cybersecurity solution.
