A challenge that many companies face is supply chain management. In an ideal world suppliers deliver fully license compliant source code releases. In reality code releases are a mix of binaries and sources, or sometimes just binaries. If these binaries are passed on (which they often are) it is necessary to check the binary components for license compliance. This is a non-trivial problem that is very time consuming and error prone when done by hand. The Binary Analysis Tool (BAT) is an Open Source tool to automate finding out what is in binaries and make license compliance easier. BAT can unpack over 30 file systems and compressed files, compare identifiers extracted from binaries to source code, create runtime linking graphs, and more. In this talk I want to introduce BAT and talk about its place in a compliance process.
