Chapter 11: Network Analysis
We're at the last chapter now but, instead of slowing things down, I believe in finishing strong. Let's have a go at some network forensics.
We've done quite a bit of acquisition and analysis thus far, including hard drive, storage, RAM, and swap file analysis to acquire, document, and analyze evidence in the hopes of finding or recovering artifacts. Let's go a step further by analyzing protocols and network communication as they may also be useful artifacts that can aid us in our investigations.
