WIRELESS RISKS ON THE RISE, SAY EXPERTSSource: Security Wire DigestPosted on December 13, 2001 Wireless network deployments are on the rise, but, the knowledge and skills needed to secure them aren't keeping pace with ever-increasing threats, say experts. "More and more companies will begin utilizing wireless and the risks are going to go through the roof," says James Foster, a senior consultant at MSSP Guardent. He points out that prior to 1995 the targets were primarily Unix- and Solaris-related, but now are Microsoft products because of widespread deployment. Foster anticipates that wireless exploits--including an assessment tool targeting access point authentication vulnerabilities--will "go up tremendously" in the next six to 12 months as wireless networks become more widely used. Those will supplement the existing cracker's arsenal of a half-dozen or so tools that sniff or actively penetrate wireless networks, Foster says. Based on the responses of more than 1,200 security professionals, a new wireless security survey conducted by Information Security magazine found that 79 percent of those polled say they're at least somewhat knowledgeable about securing wireless technology. Experts disagree with this assessment. "It strikes me as odd that three of four respondents considered themselves at least somewhat knowledgeable given that most wireless deployments are insecure," says Brad Johnson, VP of SystemExperts. Johnson says many users want wireless networking capabilities and are perfectly capable of setting one up without the help of the IT department. "You need to survey your environment to see what is out there," says Johnson. "Like the 2001 Industry Survey shows, time and time and time again we find that most intrusions and security breaches happen from the inside." While wireless networks are still in their infancy, 94 percent of respondents were concerned about the security of corporate wireless networks. "The strange thing is, we've seen so many rogue installations that everyone should be worried because you have no idea if Joe Engineer is going to install a wireless device on your network," says Dick Mackey, principal of SystemExperts. "You'd have no idea unless you went searching." While experts agree that best practices can go a long way toward securing networked data, some say existing wireless security measures are inadequate and pale in comparison to wired security. "I don't care if you use authentication and encryption," says Foster. "With wireless-accessible data, it's only a matter of time until brute-force attacks work. That's the huge difference in risk between wireless and wired networks." However, experts predict that an increase in wireless LAN exploits and war driving won't receive widespread publicity. "I believe wireless networks will be widely exploited, but people aren't going to know it's happening because most don't deploy intrusion detection under internal networks," says Phil Cox, a consultant at SystemExperts. "If the system gets compromised, they can't tell if it was from outside on the wireless LAN or a rogue employee on a hard terminal. We're going to see some high-profile cases, but not a lot because most won't know it's
happening."
