Modern IT systems tend to become more and more complex, while the number of active systems in companies increases. Furthermore, the number of security-related incidents is at an all-time high. These new conditions impose new demands on organizations. For example, it is no longer possible to manually collect and examine the systems log messages.The purpose of this thesis has been to make a comprehensive study of solutions for automated collecting and managing of log messages, analyze the Swedish Armed Forces specification for solutions for central log collection and management, and evaluating exis- ting solutions. The work consisted primarily of literature studies and evaluations of two of the Swedish Armed Forces of selected products: NetIQ Security Manager and Splunk.

Jag har under fem veckors tid utfört mitt examensarbete hos Vattenfall Vattenkraft AB i Sundsvall. Uppgiften bestod i att switchar i deras driftcentraler i Bispgården, Storuman och Vuollerim skulle bytas ut. Uppgiften kompliceras eftersom switcharna är placerade i en driftcentral med ett nätverk som ska fungera dygnet runt. I uppgiften ingick det att skapa en ny konfiguration för de nya switcharna som skulle tas i drift. Detta är den del som tagit allra mest tid.
