Businesses must be vigilant in continually evaluating their security, representatives of five leading security companies said at the ComNet Expo in Washington, D.C. this week. Denial of service attacks , website vandalism, identity theft, loss of customer information, and theft of credit card numbers are now everyday occurrences. It seems as soon as one kind of attack is thwarted, another crops up. Firewalls and anti-virus detection remain the chief methods to stop hackers, Clyde said. But businesses employing security products and services must not become complacent about protection, Blakley said.
Constant vigilance is needed.
No one has the solution to every problem that arises. If they did, the CERT Coordination Center at Carnegie Mellon University in Pittsburgh wouldn't be issuing advisories this week, he said. CERT, formerly known as the Computer Emergency Response Team, tracks Internet security vulnerabilities, provides incident response services, and publishes security alerts. This week, CERT put out alerts on four security flaws found over versions of a server that routes names used as Internet addresses through the Domain Name System and translates them into numeric addresses that can be read by computers. The vulnerabilities were found at the Internet Software Consortium's Berkeley Internet Name Domain, or BIND, server.
