The topics covered in this chapter on security analysis included detecting scans and sweeps to identify targets for planned attacks, operating system fingerprinting, detecting malformed packets, and packets that are suspiciously fragmented or sent out of order, phone home traffic from malicious agents, identifying password cracking attempts, and identifying other abnormal packets and payloads.

In the next chapter, we'll review several key command-line utilities provided in a Wireshark installation, as well as a few additional packet analysis tools that can complement your toolset.
