Security information is in high-demand as new virus attacks and stories of network intrusion continue to hit the headlines. Firewalls are a key component to a secure system - they are customisable security devices placed on a network that evaluate and route (or refuse) requests for network data that come either internally or externally via the Internet.
Personal home computer users who access the Internet, Small Office / Home Office users, and businesses of all sizes need to be concerned about the security of their systems. There are dozens of firewall options available - this book will teach you what to consider when selecting the one that's right for your system.
