To understand how data is captured, you need to understand the variety of agents. Agents are divided into three varieties:

1. Agents with all entry points written in script.

2. Agents with all entry points implemented using C/C++. The implementation of these entry points is such that:

   • Some commands get invoked from the entry points

   • Only system calls (but no commands) get executed from the entry points.

3. Hybrid agents where some entry points are written using scripts and remaining using C/C++.
