No hard evidence shows that terrorists are planning a cyberattack on the U.S. But if such an attack occurs, it is likely to be much more harmful than the current crop of relatively unsophisticated viruses and worms that have caused billions of dollars in damages, a cybersecurity expert said Monday.

Terrorism groups have planned cyberterrorism attacks for years, and those attacks are waiting for a vulnerability to trigger them, predicted Norm Laudermilch, vice president of managed security services for VeriSign.

"Anybody think we're dealing with dumb terrorists?" Laudermilch asked a crowd during a seminar on cyberterrorism at Computer Security Institute's Computer Security Conference and Exhibition here. "We're not going to have a month to patch our systems, because the plan is going to be already in place."


Consider the Source
Laudermilch classified about three-quarters of the attacks VeriSign sees on its customers' networks as "sport" attacks--those done by amateur hackers trying to see what damage they can do. And while only about 5 percent of the attacks Laudermilch sees would be classified as motivated by politics or a foreign government, companies need to be prepared when and if more of those kinds of attacks come, because enemies of the U.S. are strongly motivated by hate, he said.

"I'm not trying to be too negative, but we're dealing with a completely different type of intelligence than some of the massively successful attacks we've seen on the Internet recently," Laudermilch said.

The SQL Slammer worm, the Sobig.F worm, and the Blaster worm, all of which hit in 2003, were relatively simple attacks, and many companies recovered within hours or days, although the damage still ran into the billions of dollars.

The ability to catch these attackers is a kind of "criminal Darwinism," in which unsophisticated attackers are easily spotted, Laudermilch said, but cyberterrorism may not be so easy to recover from.

"We're good at catching the attackers who aren't so bright," he added. "But are we catching the more complex attacks? Are we catching the more stealthy attacks?"


Cybercombat
To combat the potential of cyberterrorism, companies must pay attention to several areas, Laudermilch added. Even though many U.S. companies continue to cut or hold off hiring new staff, they need to focus on security knowledge and intelligence, and effective use of intelligence, he said. Most U.S. companies fail in those two areas, he added.

Many companies do not have processes in place to even keep track of all the computers on their networks, he said, and U.S. companies are often unwilling to share their security problems with others. He called for more sharing of security data as a way for more companies to understand cyberattacks.

Companies often buy a host of security products, including firewalls, virus protection, and intrusion-detection systems, but they don't understand all the functionality those products provide, Laudermilch said. Companies often don't buy products that help them make sense of their security scans or data, or they don't take full advantage of those tools, he added. Many companies buy firewall products, spend a few hours setting them up, and rarely pay attention to them again, he said.

"The problem is once they select this technology, few people spend the time it takes to understand everything that product can do for them," he said. "Making the best use of this technology relies on your ability to take what these tools give you and turn it into intelligence."
