Digital Forensics Research Workshop
I attended the Digital Forensics Research Workshop (DFRWS 2004) in Baltimore the week of my birthday (August 12). I presented a paper detailing an architecture for distributed digital forensics analysis, which Vassil Roussev and I are developing. The major idea is to throw both more CPU power and more memory at forensics analysis. When possible, our architecture caches the entire image under investigation in RAM on the cluster. The speedups to date are dramatic. For CPU-bound analysis, like detection of stego, the speedup is roughly linear in the number of CPUs. For IO-bound stuff, like regular expression searches, we're seeing speedups of 90X using 8 machines, when we are able to cache the entire image. More as this develops.
