  • 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.

  • Network security spans a large number of disciplines, ranging from management and policy topics to operating system kernel fundamentals. Historically, the coverage of these and the other network security areas was presented in multiple, specialized publications or given a high-level treatment that was not suited to the practitioner. Network Security Bible approaches network security from the view of the individual who wants to learn and apply the associated network security best practices without having to sort through a myriad of extraneous material from multiple sources.

  • Often, several of these testing techniques are used together to gain more comprehensive assessment of the overall network security posture. For example, penetration testing usually includes network scanning and vulnerability scanning to identify vulnerable hosts and services that may be targeted for later penetration. Some vulnerability scanners incorporate password cracking. None of these tests by themselves will provide a complete picture of the network or its security posture. Table 3.1 at the end of this section summarizes the strengths and weaknesses of each test.

  • For an equivalent level of security, elliptic curve cryptography uses shorter key sizes and is considered to be an excellent candidate for constrained environments like wireless/mobile communications. In FIPS 186-2, NIST recommends several finite fields to be used in the elliptic curve digital signature algorithm (ECDSA). Of the ten recommended finite fields, five are binary extension fields with degrees ranging from 163 to 571. The fundamental building block of the ECDSA, like any ECC based protocol, is elliptic curve scalar mul- tiplication.

  • Internetworking security has become a very big issue in recent months. Companies who went through corporate life thinking, “it will never happen to me” suddenly found themselves the victim of some sort of attack on their network. High profile companies are most certainly a bigger target for several reasons, including the notoriety the hacker receives for damaging their network or Web site, and the amount of financial damage that can be done by bringing down a successful e-commerce site. Recent attacks easily racked up 100 million dollars in damage....

  • The new overwatch security pillar acts as an infection detection, containment, and remediation engine that is automatically triggered when a threat has bypassed detection by the existing "in-line" infrastructure and has infiltrated the enterprise network. The overwatch security layer uses data from a real-time reputation and behavioral correlation database to detect active data-stealing malware and other potential threats.

  • The large size, heterogeneity, and distributed nature of networks give administrators a large number of degrees of freedom to consider when configuration changes need to be made. The proper functioning of the network as a whole is a result of the coordinated configuration of multiple network elements whose interaction gives rise to the desired behaviors. The number of options to consider and the complexity of the interactions and interdependencies between various protocols and applications make it a very hard task to reason about configuration changes.
