Schneier on Security: Obama’s Cybersecurity Speech

I am optimistic about President Obama’s new cybersecurity policy and the appointment of a new “cybersecurity coordinator,” though much depends on the details.

Centralizing security responsibilities has the downside of making security more brittle by instituting a single approach and a uniformity of thinking. Unless the new coordinator distributes responsibility, cybersecurity won’t improve.

As the administration moves forward on the plan, two principles should apply. One, security decisions need to be made as close to the problem as possible. Protecting networks should be done by people who understand those networks, and threats needs to be assessed by people close to the threats. But distributed responsibility has more risk, so oversight is vital.

Two, security coordination needs to happen at the highest level possible, whether that’s evaluating information about different threats, responding to an Internet worm or establishing guidelines for protecting personal information. The whole picture is larger than any single agency.
