The Pentagon is planning to build a cyber security arm of the military--both for offensive and defense tactics. This announcement rides on the back of a message by President Obama that the US would overhaul the way overhaul the way it safeguards its computer networks. This new government agency announced by President Obama will find new ways to restrict access to government computers and protect systems that run the stock exchanges, track global banking transactions and manage the air traffic control system. The Pentagon cyber arm ( the military side ) would confront the thousands of attacks that bombard US computer systems. Currently there is debate whether the National Security Agency ( NSA ) is the appropriate overseer of the cyber security operations.
