Cisco Press Cisco Network Admission Control Volume II [Ebook-PDF]

Network Admission Control (NAC) is designed to prohibit or restrict access to the secured internal network from devices with a diminished security posture until they are patched or updated to meet the minimum corporate security requirements. A fundamental component of the Cisco® Self-Defending Network Initiative, NAC enables you to enforce host patch policies and to regulate network access permissions for noncompliant, vulnerable systems.

Cisco Network Admission Control, Volume II, helps you understand how to deploy the NAC Framework solution and ultimately build a self-defending network. The book focuses on the key components that make up the NAC Framework, showing how you can successfully deploy and troubleshoot each component and the overall solution. Emphasis is placed on real-world deployment scenarios, and the book walks you step by step through individual component configurations. Along the way, the authors call out best practices and tell you which mistakes to avoid. Component-level and solution-level troubleshooting techniques are also presented. Three full-deployment scenarios walk you through application of NAC in a small business, medium-sized organization, and large enterprise.

Firewall Policies And VPN Configurations [Ebook-PDF]

The security provided by firewalls and VPNs is only as strong as the protocol rules and policies that you create. The concepts of "defense-in-depth" and "least privilege" are merely holes in your perimeter waiting to be exploited, unless you can define and maintain protocol rules that allow only the minimum protocols required to provide your requisite services.

This book provides fundamental information necessary to configure firewalls and build VPNs and DMZs to survive the dangers of today's internet. The book includes a bonus chapter from the companion Web site on using Ethereal to monitor and analyze network traffic. While you may now feel overwhelmed by the countless firewalls with a dizzying array of features, you will feel empowered by the knowledge gained from this book. This book covers the leading firewall products. It describes in plain English what features can be controlled by a policy, and walks the reader through the steps for writing the policy to fit the objective. Because of their vulnerability and their complexity, VPN policies are covered in more depth with numerous tips for troubleshooting remote connections. Products covered include Cisco PIX Firewall, ISA Server 2004, Check Point NGX, Juniper'?s NetScreen Firewalls, SonicWall, and Nokia.

Practical VoIP Security [Ebook-PDF]

Voice Over IP (VoIP) phone lines now represent over 50% of all new phone line installations. Every one of these new VoIP phone lines and handsets must now be protected from malicious hackers because these devices now reside on the network and are accessible from the Internet just like any server or workstation.

This book will cover a wide variety of the publicly available exploit tools and how they can be used specifically against VoIP (Voice over IP) Telephony systems. The book will cover the attack methodologies that are used against the SIP and H.323 protocols as well as VoIP network infrastructure. Significant emphasis will be placed on both attack and defense techniques. This book is designed to be very hands on and scenario intensive

· More VoIP phone lines are being installed every day than traditional PBX phone lines

· VoIP is vulnerable to the same range of attacks of any network device

· VoIP phones can receive as many Spam voice mails as your e-mail can receive Spam e-mails, and as result must have the same types of anti-spam capabilities

IPSec VPN Design (2005) [Ebook-CHM]

As the number of remote branches and work-from-home employees grows throughout corporate America, VPNs are becoming essential to both enterprise networks and service providers. IPSec is one of the more popular technologies for deploying IP-based VPNs. IPSec VPN Design provides a solid understanding of the design and architectural issues of IPSec VPNs. Some books cover IPSec protocols, but they do not address overall design issues. This book fills that void.

IPSec VPN Design consists of three main sections. The first section provides a comprehensive introduction to the IPSec protocol, including IPSec Peer Models. This section also includes an introduction to site-to-site, network-based, and remote access VPNs. The second section is dedicated to an analysis of IPSec VPN architecture and proper design methodologies. Peer relationships and fault tolerance models and architectures are examined in detail. Part three addresses enabling VPN services, such as performance, scalability, packet processing, QoS, multicast, and security. This book also covers the integration of IPSec VPNs with other Layer 3 (MPLS VPN) and Layer 2 (Frame Relay, ATM) technologies; and discusses management, provisioning, and troubleshooting techniques. Case studies highlight design, implementation, and management advice to be applied in both service provider and enterprise environments.
