Network Security

A Practical Approach

Network Security is a comprehensive resource written for anyone who plans or implements network security measures, including managers and practitioners. It offers a valuable dual perspective on security: how your network looks to hackers who want to get inside, and how you need to approach it on the inside to keep them at bay.You get all the hands-on technical advice you need to succeed, but also higher-level administrative guidance for developing an effective security policy. There may be no such thing as absolute security, but, as the author clearly demonstrates, there is a huge difference between the protection offered by routine reliance on third-party products and what you can achieve by actively making informed decisions. You’ll learn to do just that with this book’s assessments of the risks, rewards, and trade-offs related implementing security measures.

Audience
Security practitioners, managers, and administrators working in IT and networking departments.
