Book excerpt: Company network administrators are compelled today to aggressively pursue a robust network security regime. This book aims to give the reader a strong, multi-disciplinary understanding of how to pursue this goal. This professional volume introduces the technical issues surrounding security as well as how security policies are formulated at the executive level and communicated throughout the organization. Readers will gain a better understanding of how their colleagues on "the other side of the fence" view the company’s security and will thus be better equipped to act in a way that forwards the company’s goals.
