In this dissertation the feasibility of creating a page-cache efficientstorage- and messaging solution with integrity geared access control for ascalable forensic framework is researched. The Open Computer ForensicsArchitecture (OCFA),a lab-side scalable computer forensics framework,introduced the concept of a message passing concurrency based forensicframework. Since then, the amount of per-investigation data to be processed ina lab environment has continued to grow significantly while available RAM andCPU processing power combined with prohibitive cost and limited capacity of SSDsolutions have shifted processing from being largely CPU constrained to beingmuch more IO constrained. OCFA suffered from several page-cache-miss relatedperformance issues that have grown more significant as a result of this shift.In the light of anti-forensics and general issues related to process integrity,OCFA did not leverage the power of its message passing based design to addressintegrity concerns.  The main purpose of this dissertation is to analyze and evaluate a number ofpage-cache friendly technologies that could contribute to the creation of acomputer forensics lab-geared scalable message-passing-concurrency basedforensic framework with a significantly reduced quantity of page-cache-missinduced spurious IO operations, taking into account integrity related issues.  Provenance logs from historic investigations conducted using the OpenComputer Forensics Architecture were thoroughly analyzed in this study, duringwhich several bottlenecks and design flaws in OCFA were identified. A number ofstrategies were devised to address these bottlenecks in future computerforensic frameworks. Finally, the most prominently page-cache relatedstrategies were consolidated with access-control measures into a user-spacefile-system and low-level API prototype.
