Security in Computing, 4th Edition

Network security is a rapidly changing field, but there are many current works and some classics everyone should read. Garfinkel and Spafford [GAR96] is an excellent place to start. For depth on hackers' tools and techniques, read Scambrey et al. [SCA01]. Some of the early works on network security have been reprinted in Davies and Price [DAV89] and Abrams and Podell [ABR87].

Anderson [AND01] presents a well-thought-out approach to putting the pieces together securely. Schneier [SCH00] presents the concepts of network security clearly.

For firewalls, Cheswick and Bellovin [CHE02] and Chapman and Zwicky [CHA00] are recent revisions of two standards. For intrusion detection systems, Northcutt [NOR00] is recommended; Allen [ALL99] and Kemmerer and Vigna [KEM02] also give good surveys of the state of the field.
