Synopses & Reviews
Intrusion Signatures and Analysis opens with an introduction into the format of some of the more common sensors and then begins a tutorial into the unique format of the signatures and analyses used in the book. After a challenging four-chapter review, the reader finds page after page of signatures, in order by categories. Then the content digs right into reaction and responses covering how sometimes what you see isn¿t always what is happening. The book also covers how analysts can spend time chasing after false positives. Also included is a section on how attacks have shut down the networks and web sites of Yahoo, and E-bay and what those attacks looked like. Readers will also find review questions with answers throughout the book, to be sure they comprehend the traces and material that has been covered.
This is the only resource security specialists need to decipher the digital fingerprints of a cyber-criminal. Ideal for self-study, it contains questions that cover the traces and signatures to allow readers to double check their knowledge.
