Abstract Microsoft’s Windows Operating System provides a logging service that collects, filters and stores event messages from the kernel and applications into log files (.evt and .evtx). Volatility, the leading open source advanced memory forensic suite, currently allows users to extract these events from memory dumps of Windows XP and Windows 2003 machines. Currently there is no support for users to extract the event logs (.evtx) from Windows Vista, Win7 or Win8 memory dumps, and Volatility users have to rely on outside software in order to do this. This thesis discusses a newly developed evtxlogs.py plugin for Volatility, which allows users the same functionality with Windows Vista, Win7 and Win8 that they had with Windows XP and Win 2003’s evtlogs.py plugin. The plugin is based on existing mechanisms for parsing Windows Vista-format event logs, but adds fully integrated support for these logs to Volatility.

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. The conclusion was that neither of the two products met the non-optional requirements posed by the specification. I personally think that the Swedish Armed Forces’ requirements specification for the central log management is far too strict and should hence be revised. A number of requirements in the current specification can be removed. Other requirements should be reformulated and/or re-evaluated. / Moderna IT-system tenderar att bli mer och mer komplexa, samtidigt som antalet ak- tiva system i ett fo ̈retag o ̈kar. Vidare a ̈r antalet sa ̈kerhetsrelaterade incidenter ho ̈gre a ̈n n ̊agonsin. Dessa nya omsta ̈ndigheter sta ̈ller nya krav p ̊a organisationer. Exempelvis a ̈r det inte la ̈ngre mo ̈jligt att manuellt samla in och granska systemens loggmeddelanden. Avsikten med den ha ̈r uppsatsen har varit att go ̈r en o ̈vergripande granskning av lo ̈sningar fo ̈r automatisk insamling och analys av loggmeddelanden, analysera de krav som Fo ̈rsvarsmakten sta ̈ller p ̊a lo ̈sningar fo ̈r central logghantering, samt utva ̈rdera befintliga lo ̈sningar. Arbetet bestod huvudsakligen av litteraturstudier samt utva ̈rderingar av tv ̊a av Fo ̈rsvarsmakten utvalda produkter: NetIQ Security Manager och Splunk. Slutsatsen blev att ingen av de tv ̊a produkterna uppfyller Fo ̈rsvarsmaktens samtliga krav fo ̈r central logghantering. Personligen anser jag att Fo ̈rsvarsmaktens kravspecifikation fo ̈r central logg- hantering a ̈r fo ̈r strikt och bo ̈r omarbetas. Ett antal krav i den nuvarande specifikationen kan med fo ̈rdel tas bort. Andra krav bo ̈r omformuleras och/eller omva ̈rderas.
