Network Intrusion Detection (3rd Edition)

This is a great book for both someone new to intrusion detection and people who already have familiarity with the field. A great, easily approachable chapter on internet basics, followed by very clear descriptions and examples. Combines specific examples with discussion of the broader context, themes, and issues around intrusion detection. And there's also a fair bit of humor and "in the trenches" feel, making the book a lor more fun to read than I thought it would be. For my purposes, I found this book the "mother lode" giving me the information and perspective I needed.
