Acknowledgments

We would like to thank the technical editors, Scott Bradley and Panos Kampanakis, for their time and technical expertise. They verified our work and contributed to the success of this book.

We would like to thank the Cisco Press team, especially Denise Lincoln and Christopher Cleveland, for their patience, guidance, and consideration. Their efforts are greatly appreciated.

Finally, we would like to acknowledge the Cisco Security Research and Operations teams. Several leaders in the network security industry work there, supporting our Cisco customers under often very stressful conditions and working miracles daily. They are truly unsung heroes, and we are all honored to have had the privilege of working side by side with them in the trenches when protecting customers and Cisco.
