Among the distinguishing characteristics of a long-term, successful IT security professional are continued learning and a constant search for examples of achievements (and failures) to learn from. Way back in the late 1930's and early 1940's at team of cryptographers at Bletchley Park, an old mansion about 50 miles outside London, broke multiple supposedly unbreakable German encryption codes, primarily those created for the also "uncrackable" Enigma machines. A highly dedicated group of unconventional warriors worked ungodly hours to unravel the codes and kept their efforts secret from even their closest friends and relatives. They succeeded, and their work is thought to have shortened the war by up to two years and saved countless lives. In October 2010, we're trying to predict new attacks, address existing vulnerabilities, survive organizational politics, explain threats realistically to managers and users, implement and maintain feasible solutions, break what sometimes seem to be unbreakable behavior patterns and chop our budgets by x percent. Are there things that even grizzled and scar-bearing professionals can learn from the efforts at Bletchley that can carry over to our mission today? We'll examine what they did and how they did it to find out. Sure, it's going on 70 years later, but there are possibly surprising parallels and some real lessons for us as we strive to develop and implement effective and workable security countermeasures.
