Peter Norton's network security fundamentals Book

The last decade has seen a fundamental shift away from stand-alone PC and toward networked systems. With increasingly large PC-based LANs and new desktop, network, and server technologies, network administrators have increasing security concerns that go beyond the standard security measures provided with the networking software.Peter Norton's Guide to Network Security provides an overview of common network types and then supplies the details necessary to build and implement a successful network security strategy. Because most commercial networks use a combination of new and legacy equipment and systems, Peter Norton's Guide to Network Security addresses the common network systems and protocols that network administrators use daily and describes the security measures necessary to keep the systems working smoothly and securely.
