Perimeter security solutions control access to critical network applications, data, and services so that only legitimate users and information can pass through the network. This access control is handled by routers and switches with access control lists (ACLs) and by dedicated firewall appliances. A firewall provides a barrier to traffic crossing a network’s “perimeter” and permits only authorized traffic to pass, according to a predefined security policy. Complementary tools, including virus scanners and content filters, also help control network perimeters.

Network connections should therefore be protected, at a level based on the risk. The assumption must be that the connecting parties are to a certain degree hostile and have to be strictly constrained to the access for which the connection was agreed. The connecting parties will, after all, have their own security policies and risk management philosophies, and these may vary considerably. Each security management domain will need to apply stringent logical access controls, and should strongly consider using firewalls and related technologies to defend their 'perimeter'....

Two areas in which automation tools would be of great use to administrators of security policies are: reasoning about policies where the goal might be, for instance, detecting inconsistencies between a new security policy rule and an existing policy; and in finding network configurations which satisfy a set of policies. Security policies expressed in terms of firewall configuration are complicated and difficult to reason about, both for man and machine.

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.

Each partition is logically isolated from the others, and must provide the same services that are available in a traditional dedicated enterprise network. The end user experience should be as if connected to a dedicated network providing privacy, security, an independent set of policies, service level, and even routing decisions. At the same time, the network administrator can easily create and modify virtual work environments for various user groups, and adapt to changing business requirements adequately.

This book was written to give the reader a well-rounded understanding of wireless network security. It looks at wireless from multiple perspectives, ranging from auditor, to security architect, to hacker. This wide scope benefits anyone who has to administer, secure, hack, or participate on a wireless network. Going through this book, the reader will see that it tackles the risk of wireless from many angles. It goes from a policy level to mitigate certain risks that wireless brings. It talks about the most cost-effective solutions to deploy wireless across a large enterprise.
