Network+ Guide to Networks, 5th Edition

Understanding the way to set up, configure, and troubleshoot a working laptop or computer community is a hugely marketable and intriguing ability. This e-book first introduces the basic construction blocks that shape a latest community, resembling protocols, topologies, undefined, and community working platforms. It then presents in-depth insurance of an important techniques in modern networking, akin to TCP/IP, Ethernet, instant transmission, and defense.

Reverse Deception: Organized Cyber Threat Counter-Exploitation

In-depth counterintelligence strategies to struggle cyber-espionage "A complete and exceptional evaluation of the subject via specialists within the box. "--Slashdot disclose, pursue, and prosecute the perpetrators of complex power threats (APTs) utilizing the validated protection thoughts and real-world case experiences featured during this extraordinary consultant.

Physical-Layer Security for Cooperative Relay Networks

This e-book provides physical-layer defense as a promising paradigm for attaining the information-theoretic secrecy required for instant networks. It explains how instant networks are super at risk of eavesdropping assaults and discusses a number of protection options together with information-theoretic safety, man made noise aided safeguard, security-oriented beamforming, and variety assisted defense methods.

Sample text

You will learn that the DMZ is publicly accessible, so failing to harden these systems almost guarantees your network will be hacked and exploited. In this chapter we look at Sun Solaris bastion hosts, configuring the fundamentals, controlling access to resources, auditing access to resources, authentication, and all the hardening you need to lock down your systems. The chapter covers the hardening details as well as showing you how to configure security, set up remote administration of DMZ hosts, vulnerability-scan your hosts, and implement advanced host security.

A DMZ is a method of providing segregation of networks and services that need to be provided to users, visitors, or partners through the use of firewalls and multiple layers of filtering and control to protect internal systems. The book contains not only the theory but the “how to” information that you will need in order to be successful in protecting your internal networks from attack. Information is available about different hardware and software implementations (including Cisco PIX, Nokia, Check Point, Microsoft ISA Server, and others) that you will find useful in planning and implementing your DMZ.
