Open Source Security Information Management system supporting IT security audit

Nowadays, assuring security of computer systems becomes difficult due to the rapid development of IT technologies, even in household appliances. This article shows exemplary model of the IT security monitoring and management system. Proposed solution is aimed to collect security events, analyse them, assess the risk they bring and inform the administrator about them in order to take appropriate decision to mitigate potential security incident. This system is based on open source code toolset. This toolset was studied, tested and examined in the context of the whole system. These tools were configured and an additional code was developed in order to achieve synergy effect from adopting various techniques aimed at network monitoring and system security.
