Network Perimeter Security: Building Defense In-Depth
Today’s network administrators are fully aware of the importance of security; unfortunately, they have neither the time nor the resources to be full-time InfoSec experts. Oftentimes quick, temporary security fixes are the most that can be expected. The majority of security books on the market are also of little help. They are either targeted toward individuals pursuing security certifications or toward those interested in hacker methods. These overly detailed volumes fail to deliver the easily referenced tactical information needed to provide maximum security within the constraints of time and budget. Network Perimeter Security: Building Defense In-Depth reveals how you can evaluate the security needs of your network, develop a security policy for your company, and create a budget based upon that policy. It assists you in designing the security model, and outlines the testing process. Through the concepts and case studies presented in this book, you will learn to build a comprehensive perimeter defense architecture based upon multiple layers of protection, with expert recommendations for configuring firewalls, routers, intrusion detection system, and other security tools and network components. This detailed volume enables you to secure your network on time, within budget, and without having to pursue attain a security certification.
