According to a report from a presidential technology council, the US government is not setting a good example in cybersecurity. The report comes from the President's Council of Advisors on Science and Technology. According to the report, "the Federal Government rarely follows accepted best practices." The report further states that "Cybersecurity will not be achieved by a collection of static precautions, it requires a set of processes that continuously couple information about an evolving threat to defensive reactions and responses."
