The United States has begun talks with Russia and a United Nations arms control committee about strengthening Internet security and limiting military use of cyberspace.

The Russians have held that the increasing challenges posed by military activities to civilian computer networks can be best dealt with by an international treaty, similar to treaties that have limited the spread of nuclear, chemical and biological weapons. The United States had resisted, arguing that it was impossible to draw a line between the commercial and military uses of software and hardware.

A State Department official, who was not authorized to speak about the talks and requested anonymity, disputed the Russian characterization of the American position. While the Russians have continued to focus on treaties that may restrict weapons development, the United States is hoping to use the talks to increase international cooperation in opposing Internet crime. Strengthening defenses against Internet criminals would also strengthen defenses against any military-directed cyberattacks, the United States maintains.

The American interest in reopening discussions shows that the Obama administration, even in absence of a designated Internet security chief, is breaking with the Bush administration, which declined to talk with Russia about issues related to military attacks using the Internet.
