“OSSIM is a fully featured SIM solution that offers all
the necessary functionality, ranging from the detection at
low-level to high-level reporting.“Founded in 2003 by AlienVault, OSSIM is at the time of this
writing the de-facto standard in Open Source Security Information
Management. Indeed, AlienVault claims to have an installed user
base exceeding 10,000 units, which accounts for half of the
installed SIM market. Based on GNU/Linux Debian, kernel 2.6, OSSIM
takes advantage of the wealth of free software “gems”, by
integrating a handy suite of security open source tools, among
which:* OSSEC Host Intrusion Detection System;
* OpenVAS Vulnerability Assessment Scanner;
* OCS Inventory;
* Nagios Availability Monitor;
* Nmap Port Scanner;
* etc.”
