"Israel inched a step closer on Wednesday to deploying the Iron Dome missile defense system along the border with the Gaza Strip after it successfully intercepted a number of missile barrages in tests held in southern Israel this week. Iron Dome successfully... The tests were overseen by the Defense Ministry, the Israel Air Force and Rafael Advanced Defense Systems Ltd., which developed the Iron Dome, slated to become operational and be deployed along the Gaza border in mid-2010. The missile volleys which the system succeeded in intercepting included a number of rockets that mimicked Kassam and longer range Grad-model Katyusha rockets that are known to be in Hamas's arsenal. The Iron Dome is supposed to be capable of intercepting all short-range rockets fired by Hamas in the Gaza Strip and by Hizbullah in Southern Lebanon. The system uses an advanced radar made by Elta that locates and tracks the rocket, which is then intercepted by a kinetic missile interceptor. During the test, the radar succeeded in detecting which rockets were headed towards designated open fields and therefore did not launch an interceptor to destroy them. The IDF has formed a new battalion that will be part of the IAF's Air Defense Division and will operate the Iron Dome. Prototypes have been supplied to the new unit, which has already begun training with the systems."

"The world's largest Internet search company and the world's most powerful electronic surveillance organization are teaming up in the name of cybersecurity. Under an agreement that is still being finalized, the National Security Agency would help Google analyze a major corporate espionage attack that the firm said originated in China and targeted its computer networks, according to cybersecurity experts familiar with the matter. The objective is to better defend Google -- and its users -- from future attack. Google and the NSA declined to comment on the partnership. But sources with knowledge of the arrangement, speaking on the condition of anonymity, said the alliance is being designed to allow the two organizations to share critical information without violating Google's policies or laws that protect the privacy of Americans' online communications. The sources said the deal does not mean the NSA will be viewing users' searches or e-mail accounts or that Google will be sharing proprietary data. The partnership strikes at the core of one of the most sensitive issues for the government and private industry in the evolving world of cybersecurity: how to balance privacy and national security interests. On Tuesday, Director of National Intelligence Dennis C. Blair called the Google attacks, which the company acknowledged in January, a "wake-up call." Cyberspace cannot be protected, he said, without a "collaborative effort that incorporates both the U.S. private sector and our international partners." But achieving collaboration is not easy, in part because private companies do not trust the government to keep their secrets and in part because of concerns that collaboration can lead to continuous government monitoring of private communications. Privacy advocates, concerned about a repeat of the NSA's warrantless interception of Americans' phone calls and e-mails after the Sept. 11, 2001, terrorist attacks, say information-sharing must be limited and closely overseen.
