Senior defense officials expressed confidence that Israel's military networks were secure and protected from cyber attacks, as Strategic Affairs Minister Moshe Ya'alon hinted on Tuesday that Israel might have been behind the latest computer virus to attack Iran. Yaalon said that Israel's defenses were good and were more advanced than those that exist in the civilian world. He added that all of Israel's systems were protected with various layers. Last year the IDF established a Cyber Defense Division in the C4I Directorate, which is responsible for protecting army networks from hackers and infiltrators. Evidence suggests that the virus, dubbed "Flame," may have been developed on behalf of the same nation or nations that commissioned the Stuxnet worm that attacked Iran's nuclear program in 2010.
