cfengine is a language based system specifically designed
for testing and configuring unix-like systems attached to
a TCP/IP network. Cfenvd is part of the anomaly detection
subsystem for cfagent. It is a "plug'n'play" module
that provides machine learning support to the agent.
Cfenvd requires no configuration. It is completely optional.
If it is run, cfagent can extract useful data from it; if
it is not run cfagent continues as usual.
It is part of the on-going research in anomaly detection
using cfengine.
