Acknowledgments

I want to thank the technical editors, John Stuppi and Lou Ronnau, for their time and technical expertise. They verified my work and corrected me in all the major and minor mistakes that were hard to find.

I also want to thank the Cisco Press team, especially Denise Lincoln, Chris Cleveland, and Mandie Frank for their patience, guidance, and consideration. Their efforts are greatly appreciated.

Kudos to the Cisco product development teams for delivering such a great product portfolio.

Finally, I want to acknowledge the Cisco PSIRT and Security Research and Operations. Some of the best and brightest minds in the network security industry work there, supporting and protecting our Cisco customers, often under very stressful conditions and working miracles daily.
