IseHarvest is a network analysis tool designed as a framework for extracting data from TCP streams. Once extracted, it reconstructs the data into individual files and documents from captured network traffic, saving the data locally. Besides being a framework, IseHarvest passively extracts HTTP data from captured traffic and reconstructs files and web directory layouts in such a way to enable web content monitoring of network resources. By re-linking HTML and CSS files, it provides an after the fact visual of how web sites were viewed over a network and a look at how corresponding web servers are laid out by looking at only captured files.
