U.S.-Australia Cyberwar Treaty
The long-standing ANZUS military treaty now includes cyberspace attacks:
According to Reuters, the decision was made in discussions between the two countries this week. The extension of the treaty would mean that a cyber-attack on either country would be considered an attack on both.
Exactly what this means in practice is less clear: practically every government with a connection to the Internet is subject to pretty much constant attack, and both Australia and America regularly accuse China and North Korea of playing host to many such attacks (China just as regularly denies any government involvement in Internet-borne attacks).
According to Reuters, it’s the first time any non-NATO defense pact has extended to the Internet. US Defence Secretary Leon Panetta is quoted as saying “cyber is the battlefield of the future.”
