The Subukan Sensor is a complete Network Intrusion Detection System (NIDS) platform. It is not simply an application one can install on an existing operating system. Rather, Subukan is a total software solution including both an operating system and a unique compilation of security tools. It is based on a single file image or firmware that transforms almost any hardware equipment into a fully functional NIDS appliance. Appliance- based technology simplifies administration and provides the capability for remote upgrades.
Zibu is a small tool that allows you to cyclically compare access permissions and checksums of files provided by users, with a database generated at first run (to be exact, generated with --init or --update mode). But its main feature is restoring valid access permissions, and/or executing your commands when checksums are invalid.
Logger is a log queueing and optimization utility. It can completely replace sys/klogd, handle logs larger than 2GB, perform automatic nightly log rotation without affecting services, and transfer logs between machines via TCP connections. Any application that writes a text log can be maintained by Logger. It is light, small, and fast, emphasizes security, and reduces drive usage through memory queueing.

It can store information about all of your network devices, and allows you to track all changes and updates made to the device.
