The NIST, has come out with a recommendation for all Federal government agencies to mount mock attacks to see the robustness and effectivity of security and penetration prevention measures/countermeasures that are employed. This due to alarming events that have happened to the British Government�s Tax Offices of junior government people getting hold and rights to download supposedly secure data from government servers. The US Government IT branch recommends that it be done on undisclosed schedules and employ rotating modes of attack to see if all the security in place is doing its job of protecting the information it is supposed to protect.
