Information security has become an extremely important topic for everyone over the past few years. In today’s environment the number of touch points between an organization’s information assets and the outside world has drastically increased: millions of customers can interact via a Web site, thousands of employees and partners may connect using Virtual Private Network s (VPNs), and dozens of critical applications may be completely outsourced to application service providers (ASPs).The deployment of wireless LANs also means that users no longer even need a physical connection to the network to gain access.
A critical strategy for reducing security risk is to practice defense-in-depth.The essence of defense-in-depth is to create an architecture that incorporates multiple layers of security protection. Recognizing this requirement, Cisco Systems has placed a high priority on security and offers a wide range of stand-alone and integrated security products. Managing Cisco Network Security, Second Edition is important to anyone involved with Cisco networks, as it provides practical information on using a broad spectrum of Cisco’s security products. Security is not just for “security geeks” anymore. It is an absolute requirement of all network engineers, system administrators, and other technical staff to understand how best to implement security.
In addition to providing a general understanding of IP network security and the threat environment, this book offers detailed and practical information on how to use Cisco’s suite of security products. Callisma’s contributing authors are industry experts with real world implementation experience. Each chapter will guide you through a particular aspect of security, from the family of PIX firewalls, to the Cisco Secure Intrusion Detection System (IDS), to traffic filtering in IOS, to the Cisco Secure Policy Manager (CSPM). In reading this book, you will obtain a firm understanding of how to secure your Cisco network.
