Richard Bejtlich, from TAO Security, did a presentation on network security monitoring using FreeBSD.
In this presentation I’ll discuss my latest thinking on using FreeBSD to identify normal, suspicious, and malicious traffic in enterprise networks. FreeBSD is a powerful platform for network traffic inspection and log analysis, and I’ll share a few ways I use it in production environments.
3. FreeBSD supported branches update
The branches supported by the FreeBSD Security Officer have been updated to reflect the EoL (end-of-life) of FreeBSD 7.0. The new list is below and at . Please note that FreeBSD 7.0 was originally announced with an EoL date of February 28, 2009, but the EoL was delayed by two months in order to allow a 3 month window for systems to be upgraded to FreeBSD 7.1.

The current designation and estimated lifetimes of the currently supported branches are given below. TheEstimated EoL (end-of-life) column gives the earliest date on which that branch is likely to be dropped. Please note that these dates may be extended into the future, but only extenuating circumstances would lead to a branch’s support being dropped earlier than the date listed.
After a fresh install, it is important to harden the security on a server before it hits your network for use. Not only making configuration changes aid in the security of your box, but there are some practical rules to abide by. These are some hardening tips to make your FreeBSD box more secure and will apply to both the 5.x and 4.x branches, but I will assume you are running 5.x. If a 4.x change is different, I will note it.
Dave Lawlor has put together some really easy-to-follow instructions on how to install and configure FreeNAS.
FreeNAS is a free NAS (Network-Attached Storage) server, supporting: CIFS (samba), FTP, NFS, AFP, RSYNC, iSCSI protocols, S.M.A.R.T., local user authentication, Software RAID (0,1,5) with a Full WEB configuration interface. FreeNAS takes less than 32MB once installed on Compact Flash, hard drive or USB key. The minimal FreeBSD distribution, Web interface, PHP scripts and documentation are based on M0n0wall.
There are a couple of othergoodhowtos available but this one by far the easiest to follow, AND the screenshots are of the latest FreeNAS version (changed GUI).
