SecurityHenWen
HenWen is a network security package for Mac OS X that makes it easy to configure and run Snort, a free Network Intrusion Detection System (NIDS). HenWen’s goal is to simplify setting up and maintaining software that will scan network traffic for undesirable traffic a firewall may not block. Everything you need to have is bundled in; there is no compiling or command line use necessary.
