Abstract

This talk introduces cross-drive analysis (CDA), a new approach for performing
analysis of forensic data sets that are too large or complex to be analyzed with
today's existing tools. CDA works by performing systematic information
extraction and cross-correlation across an entire data set.
CDA was used to analyze 182 disk drives acquired on the secondary market; it automatically
identified drives containing a high concentration of
confidential financial records and three pairs of drives, each previously
used by the same organization. CDA shows strong
promise in allowing forensic examiners to prioritize their work and
in automatically identifying members of preexisting social networks.
