Review: Practical Packet Analysis
In the introduction, McIlwraith points out that security awareness
training properly consists of communication, raising of issues, and
encouragement to modify behaviour. (This will come as no surprise
to those who recall the definition of training as the modification
of attitudes and behaviour.) He also notes that security professionals
frequently concentrate solely on presentation of problems. The
remainder of the introduction looks at other major security
activities, and the part that awareness plays in ensuring that
they actually work.

Robert Slade Review: "Information Security and Employee Behaviour"
The best way to secure you against sniffing is to use encryption. While
this won't prevent a sniffer from functioning, it will ensure that what a
sniffer reads is pure junk.
