National Institute of Standards

"First, the Beacon-generated numbers cannot be predicted before they are published. Second, the public, time-bound, and authenticated nature of the Beacon allows a user application to prove to anybody that it used truly random numbers not known before a certain point in time. Third, this proof can be presented offline and at any point in the future."

Doubting the National Institute of standards randomness beacon is tin-foil-hat crazy.

The Terry Childs case is interesting, I think, because everybody involved was at fault. The California political machine for putting career politicians in charge, the city administrators who were so focused on the bottom line during a recession that they let a very strange person control the network; and Terry himself, who considered the network to be personal property and was actually denying service for personal reasons.

For more details, you could try listening to one of those self-congratulatory talks that Jeana Pieralde has been giving. I found out about her from the Healthy Paranoia podcast.

One practical solution is to keep anybody from having 24/7/365 access to any critical resource. I just read about bank security, and reportedly they require everybody to take at least a week of vacation every year, so nobody is in a position to keep a discrepancy secret. That would be interesting to apply to system and network administrators, too.

That is a terrible title. By using "who" instead of "whom," you have inverted the meaning of the sentence.

Somehow this brief article managed to encompass what many SA's, DBA's, NA's, programmers attempt to grasp as a single thought. I greatly appreciate the down to earth, candid approach of the writer. Security has no alpha and omega. "...a belt-and-suspenders world" Excellent job - now if we can expose programmers from day one.... Cheers, Patrick S. Lockett
