How forensic tools recover digital evidence - Data structures

In a previous post I covered “The basics of how digital forensics tools work.” In that post, I mentioned that one of the steps an analysis tool has to do is to translate a stream of bytes into usable structures. This is the first in a series of three posts that examines this step (translating from a stream of bytes to usable structures) in more detail.

In this post I’ll introduce the different phases that a tool (or human if they’re that unlucky) goes through when recovering digital evidence. The second post will go into more detail about each phase. Finally, the third post will show an example of translating a series of bytes into a usable data structure for a FAT file system directory entry.
