Piers McMahon, senior business manager for the eTrust suite of security products at Computer Associates, agrees that different traffic types must be monitored. ETrust detects known attack patterns at the network, server and application layers. The product also provides streaming updates so that IT managers and security professionals don't have to manually update servers. Using Trojan horses, they're getting users to trustingly connect to a site that may be malicious or may deposit malicious code. They're avoiding the front door because they know you're watching it.
Most companies have a false sense of security.
Not everyone does. Kurt Ziegler, chairman and CEO of traffic analysis vendor eBSure, was so concerned about his com-pany's security, he included a security plan and budget in his initial business plan. Ziegler, who once headed security for Computer Associates, is familiar with the security risks software companies face. Some of the firewall vendors claimed to be doing intrusion detection, but Ziegler went with Riptech because it offers an intrusion detection and firewall system that supports VPNs. All three of those elements are affected by being connected to the network.
