University of California, Irvine (UCI) researchers are developing new cybersecurity methods designed to thwart botnets and other types of cyberattacks. UCI's Michael Goodrich and Gene Tsudik, co-directors of the university's Secure Computing & Networking Center, say the challenges are mounting.

Goodrich says that although viruses have been a problem for a long time, the proliferation of networking has made security a bigger issue than ever. "There are all these problems popping up now that are a little more insidious," he says.

The increasing use of radio-frequency identification (RFID) also presents security concerns. Information transmitted using RFID tags can be intercepted because the information is transmitted wirelessly. Eavesdropping becomes very easy when radio waves carry vital information because only an antenna and a computer that can decode the signal are needed to access the information, Tsudik says.

"What we do is focus on authentication, integrity and authorization — factors in any solution," Goodrich says. "We're trying to learn how to protect against things we've never even thought of."
