Traditionally, network security (firewalls to block unauthorized users, Intrusion Prevention Systems (IPS) to keep attackers out, Web filters to avoid misuse of Internet browsing, and antivirus software to block malicious programs) required separate boxes with increased cost and complexity. Unified Threat Management (UTM) makes network security less complex, cheaper, and more effective by consolidating all these components.

The goal in writing Network Intrusion Detection, Third Edition has been to empower you as an analyst. We believe that if you read this book cover to cover, and put the material into practice as you go, you will be ready to enter the world of intrusion analysis. Many people have read our books, or attended our live class offered by SANS, and the lights have gone on; then, they are off to the races. We will cover the technical material, the workings of TCP/IP, and also make every effort to help you understand how an analyst thinks through dozens of examples.

With the arrival of IEEE 802.11b (a.k.a. WiFi) and other wireless networking technologies on the market comes a wave of stories about snoops intercepting sensitive LAN traffic from out in the company parking lot or across the concourse at the airport. Hack Proofing Your Wireless Network takes a look at strategies for defending wireless LANs--those based on Bluetooth and IEEE 802.11a as well as WiFi--against signal interception and other attacks peculiar to their wireless nature.

Most Systems Administrators are not security specialists. Keeping the network secure is one of many responsibilities, and it is usually not a priority until disaster strikes. How to Cheat at Securing Your Network is the perfect book for this audience. The book takes the huge amount of information available on network security and distils it into concise recommendations and instructions, using real world, step-by-step instruction.

Shocks to regional, national, and global systems stemming from natural hazards, acts of armed violence, terrorism, and transnational crime have significant defence and security implications. Today, nations face an uncertain and complex security landscape in which threats impact/target the physical, social, economic, and cyber domains. For example, acts of terrorism and organized crime are considered one of the greatest threats to national security. In the UK alone, the social and economic costs associated with organized crime are estimated between £20 and £40 billion per year.

This eBook examines different aspects of network security metrics and their application to enterprise networks. One of the most pertinent issues in securing mission-critical computing networks is the lack of effective security metrics which this book discusses in detail. Since “you cannot improve what you cannot measure”, a network security metric is essential to evaluating the relative effectiveness of potential network security solutions.

Nmap is a well known security tool used by penetration testers and system administrators. The Nmap Scripting Engine (NSE) has added the possibility to perform additional tasks using the collected host information. Tasks like advanced fingerprinting and service discovery, information gathering, and detection of security vulnerabilities. Network exploration and security auditing cookbook will help you master Nmap and its scripting engine.

Protection of sensitive information from adversaries has been a practice since centuries. As children, many of us had magic decoder rings for exchanging coded messages with our friends and possibly keeping secrets from parents, siblings or teachers. Sensitive information will be passed on between allies at war times. Cryptographic methods were traditionally used to prevent the enemy from learning sensitive military information.  As society has evolved, the need for more sophisticated methods of protecting data has increased.

The best-selling Stealing the Network series reaches its climactic conclusion as law enforcement and organized crime form a high-tech web in an attempt to bring down the shadowy hacker-villain known as Knuth in the most technically sophisticated Stealing book yet. Stealing the Network: How to Own a Shadow is the final book in Syngress’ ground breaking, best-selling, Stealing the Network series. As with previous title, How to Own a Shadow is a fictional story that demonstrates accurate, highly detailed scenarios of computer intrusions and counter-strikes.

Here's easy-to-understand book that introduces you to fundamental network security concepts, principles, and terms, while providing you with practical techniques that you can apply on the job. It helps you identify the best type of intrusion detection system for your environment, develop organizational guidelines for passwords, set general computer security policies, and perform a security review and risk assessment .

This second edition of Network Security Hacks is a grimoire of 125 powerful security techniques. This volume demonstrates effective methods for defending your servers and networks from a variety of devious and subtle attacks. Within this book are examples of how to detect the presence (and track every keystroke) of network intruders, methods for protecting your network and data using strong encryption, and even techniques for laying traps for would-be system crackers. Many important security tools are presented, as well as clever methods for using them to reveal real, useful information about what is happening on your network.
