Feds, Industry, Battle the Biggest Bug
Four months after a public advisory warned of security vulnerabilities in a ubiquitous Internet remote management protocol, there have been no widespread attacks exploiting the holes. But technology companies and a special U.S. government panel are quietly evaluating the threat of related vulnerabilities in some of America's most critical electronic infrastructures, including the telephone network, the power grid, and the next generation of air traffic control systems.
On February 12th, Carnegie Mellon's Computer Emergency Response Team (CERT) issued a high-profile alert about serious security holes in dozens of implementations of the Simple Network Management Protocol (SNMP) -- the Internet's standard language for monitoring and controlling routers, switches and other devices. It was big news in itself, with nearly two hundred companies forced to evaluate, and in some cases patch, their products. Perhaps owing to CERT's careful behind-the-scenes advance coordination with vendors, months later there have been no reports of mass exploitation of the vulnerabilities.
