The book uses straightforward language to introduce topics andto show the features, mechanics, and functionality of various networksecurity devices. A series of case studies helps illuminate conceptsand shows how you can apply the concepts to solve real-world problems.
Divided into four parts, Network Security Fundamentalstakes you on a tour of all the essential technologies and moderndefenses at your disposal to help you maintain network uptime and dataintegrity. Part I covers the basics, introducing terms and concepts andlaying the foundation of a solid security structure. The discussionfocuses on weaknesses and vulnerabilities along with an overview of thetraditional defenses used to thwart attacks. Part II examines twocomponents of security-cryptography and security policies. Part IIIlooks at the various security components. Separate chapters cover websecurity, router security, firewalls, intrusion detection systems(IDS), remote access security, virtual private networks (VPN), PublicKey Infrastructure (PKI), wireless security, and logging and auditing.Each chapter in this section is a self-contained tutorial, allowing youto skip to those topics of greatest interest or primary concern. PartIV includes several reference appendixes, including the Cisco SAFEBlueprint, NSA guidelines, and SANS policies.
