From the chaos of the early DARPA, ARPANET and NSF-funded NSFNET has emerged a globe-spanning communications facility we today call simply ?The Internet.? It has become so commonplace and so taken for granted that Wired News has decreed that writers should no longer capitalize it. This tale is not singularly focused on the past. It tells not only how we got here, but where we think the Commercial Internet must go. For all its greatness, today's Internet has serious shortcomings. Theft of personal data, identity theft, online scams, and advertising fraud run rampant, with online dollars diverted to organized crime. Insecure systems, poor security practices and an attitude of secrecy and reluctance to acknowledge failings inhibit real solutions. We propose a way forward, a networking future that is bright, optimistic, and secure.

The world of IT is always evolving, but in every area there are stable, core concepts that anyone just setting out needed to know last year, needs to know this year, and will still need to know next year. The purpose of the Foundations series is to identify these concepts and present them in a way that gives you the strongest possible starting point, no matter what your endeavor. Network Security Foundations provides essential knowledge about the principles and techniques used to protect computers and networks from hackers, viruses, and other threats. What you learn here will benefit you in the short term, as you acquire and practice your skills, and in the long term, as you use them. Topics covered include: Why and how hackers do what they do How encryption and authentication work How firewalls work Understanding Virtual Private Networks (VPNs) Risks posed by remote access Setting up protection against viruses, worms, and spyware Securing Windows computers Securing UNIX and Linux computers Securing Web and email servers Detecting attempts by hackers

Showing how to improve system and network security, this guide explores the practices and policies of deploying firewalls, securing network servers, securing desktop workstations, intrusion detection, response, and recovery.

Targeting this work at computer/network security administrator at a reasonably large organization (described as an organization that finds it necessary to have a security team), Wadlow (the cofounder of a company specializing in Internet security) covers such topics as the nature of computer attacks, setting security goals, creating security network designs, team building, fortifying network components, implementing personnel security, monitoring networks, discovering and handling attacks, and dealing with law enforcement authorities.

Expert solutions for securing network infrastructures and VPNs bull; Build security into the network by defining zones, implementing secure routing protocol designs, and building safe LAN switching environments Understand the inner workings of the Cisco PIX Firewall and analyze in-depth Cisco PIX Firewall and Cisco IOS Firewall features and concepts Understand what VPNs are and how they are implemented with protocols such as GRE, L2TP, and IPSec Gain a packet-level understanding of the IPSec suite of protocols, its associated encryption and hashing functions, and authentication techniques Learn how network attacks can be categorized and how the Cisco IDS is designed and can be set upto protect against them Control network access by learning how AAA fits into the Cisco security model and by implementing RADIUS and TACACS+ protocols Provision service provider security using ACLs, NBAR, and CAR to identify and control attacks Identify and resolve common implementation failures by evaluating real-world troubleshooting scenarios As organizations increase their dependence on networks for core business processes and increase access to remote sites and mobile workers via virtual private networks (VPNs), network security becomes more and more critical. In today's networked era, information is an organization's most valuable resource. Lack of customer, partner, and employee access to e-commerce and data servers can impact both revenue and productivity. Even so, most networks do not have the proper degree of security. Network Security Principles and Practices provides an in-depth understanding of the policies, products, and expertise that brings organization to this extremely complex topic and boosts your confidence in the performance and integrity of your network systems and services. Written by a CCIE engineer who participated in the development of the CCIE Security exams, Network Security Principles and Practices is the first book that provides a comprehensive review of topics important to achieving CCIE Security certification. Network Security Principles and Practices is a comprehensive guide to network security threats and the policies and tools developed specifically to combat those threats. Taking a practical, applied approach to building security into networks, the book shows you how to build secure network architectures from the ground up. Security aspects of routing protocols, Layer 2 threats, and switch security features are all analyzed. A comprehensive treatment of VPNs and IPSec is presented in extensive packet-by-packet detail. The book takes a behind-the-scenes look at how the Cisco PIX(r) Firewall actually works, presenting many difficult-to-understand and new Cisco PIX Firewall and Cisco IOSreg; Firewall concepts. The book launches into a discussion of intrusion detection systems (IDS) by analyzing and breaking down modern-day network attacks, describing how an IDS deals with those threats in general, and elaborating on the Cisco implementation of IDS. The book also discusses AAA, RADIUS, and TACACS+ and their usage with some of the newer security implementations such as VPNs and proxy authentication. A complete section devoted to service provider techniques for enhancing customer security and providing support in the event of an attack is also included. Finally, the book concludes with a section dedicated to discussing tried-and-tested troubleshooting tools and techniques that are not only invaluable to candidates working toward their CCIE Security lab exam but also to the security network administrator running the operations of a network on a daily basis.

Build Your Network Security Career on a Solid Foundation Whether you're setting out to earn a security certification or just want to know more about the security issues faced by all network administrators, Network Security JumpStart is the place to begin. Inside, a networking expert demystifies every aspect of the growing security imperative, giving you a firm footing from which you can realize your goals and develop a better understanding of computer and network security. Coverage Includes: Understanding security principles Understanding hacking Using encryption and authentication Managing security Securing Internet connections Using Virtual Private Networks Securing remote and home users Implementing virus protection Creating fault tolerance Securing Windows servers Securing UNIX servers Securing public web servers Securing public e-mail servers Detecting intrusion

Corporate network security issues still very much fill the media today. "Designing Network Security" offers a practical approach to the implementation of secure network design, offering the additional bonus of Cisco specific perspectives and case studies.
