I am currently writing a university assignment on Unix Security.

I would be grateful if you guys could help me out...

What, in your minds, are the most common (top five) and potentially
most exploitable security risks that you see in Unix/Linux
deployments?

These can be simple as poor inetd.conf or user administration/policy
based and can range to the more complicated/technical.

I look forward to hearing from you,

Ben
