Recently I have been taking various training courses and tests covering different aspects of computing and network security.  I’d like to share some of my experience and opinions here.

Brainbench:  I took the free Computer Forensics, and Network Security tests they offered.  These were fairly comprehensive tests, and I thought they gave me a pretty decent representation of my knowledge.  As far as the applicability of the tests though, there does not appear to be very much merit as far as a bullet on your resume, so I would reccomend these purely for self-assessment purposes.

SANS:  In prepration for the GSEC test I have taken the practice exams, and they seem to be pretty much what they are advertised to be, not quite as difficult as the real thing, but definitely required knowledge of the material.  I feel more confident in taking my test after taking these practice exams.

CERT VTE:  I completed the Forensic Specialist course on here, and while there is no test, the sheer volume of information is staggering.  There are also extremely detailed labs available which actually put you into virtual machine and let you accomplish a set of tasks.  Absolutely wonderful stuff.
