Today almost anyone can become ahacker by downloading tools from the Internet. These complicated attack tools and generallyopen networks have generated an increased need for network security and dynamic securitypolicies.The easiest way to protect a network from an outside attack is to close it off completely fromthe outside world. A closed network provides connectivity only to trusted known parties andsites; a closed network does not allow a connection to public networks.Because they have no Internet connectivity, networks designed in this way can be consideredsafe from Internet attacks. However, internal threats still exist.There is a estimates that 60 to 80 percent of network misuse comes from inside the enterprisewhere the misuse has taken place.With the development of large open networks, security threats have increased significantly inthe past 20 years. Hackers have discovered more network vulnerabilities, and because youcan now download applications that require little or no hacking knowledge to implement,applications intended for troubleshooting and maintaining and optimizing networks can, inthe wrong hands, be used maliciously and pose severe threats.An adversaryA
