Web sites work to punch holes in corporate Web filters
In an enterprise like Washington Group International Inc., which has 20,000 employees and locations across the globe, there's always the chance someone will try to visit Web sites or use programs that are forbidden by company policy.
Ed Biancarelli, senior IT security director for the Boise, Idaho-based engineering, construction and management firm, has strict Web-use policies banning peer-to-peer (P2P) programs as well as porn and gambling Web sites. He uses an intrusion prevention (IPS) appliance to block workers from violating that policy, but he's found that even the strongest of security tools can't keep everyone from doing what they shouldn't.
"We are not a high-tech company, so the threat of people circumventing the policies is not widespread," he said. "But we have had instances of uncovering P2P file sharing and there are people using IM and we don't allow that." Web sites work to punch holes in corporate Web filters
