Wireless connectivity is now a reality in most businesses. Yet by its nature, wireless networks are the most difficult to secure and are often the favorite target of intruders. Some of the primary threats are the result of the following factors:
Denial of service (DoS) and other network layer attacks
Unauthorized access across the perimeter and within the organization
Application layer intrusions and attacks, both from within and outside the network
Extended connectivity through remote access and extranets
An increase in unmanaged or ill-managed endpoint devices
New applications like VoIP, instant messaging, and peer-to-peer
This book provides the busy network administrator with best-practice solutions address these threats and to maintain a secure and accessible wireless network. The book endorses the principle that the best strategy is to deploy multiple layers of security, each reinforcing the other. Yet it never strays from its emphasis on the practical; that any tool or methodology that is deployed must work reliably, allow sufficient access, and require a minimal amount of maintenance.
