2. Ignoring the human element of security


Today's network admins have access to a dizzying array of security tools. But as hacker Kevin Mitnick is fond of saying, the weakest link in any network is its people. The most fortified network is still vulnerable if users can be tricked into undermining its security -- for example, by giving away passwords or other confidential data over the phone.

For this reason, user education should be the cornerstone of your IT security policy. Make users aware of potential social engineering attacks, the risks involved, and how to respond.
