Topics:Firewalls, Network Security and Applications, Security Architecture, Security Implementation
Origin:Community Contributions (2004)
Type:Effective Practices
Abstract:

The customized OpenBSD distribution used for the firewall was originally developed for use as an all-in-one Snort-based IDS sensor. The larger need for firewalls as opposed to IDS, however, motivated IT Security & Policy at Purdue to modify the platform to support its use as a bridging firewall as well. The initial customization of the OpenBSD distribution took one staff member approximately two months to develop and another two weeks to modify it for use as a bridging firewall. Currently, IT Security & Policy manages 15 bridging firewalls centrally, with several more deployed and managed independently by various departments.
