Every once in a while, I see some new security development that really sets me on edge. The latest one is courtesy of DERA (Defense Evaluation and Research Agency), an agency of the MoD (Ministry of Defense) in Britain. Like many agencies that deal with computer security, they periodically come out publically with some new idea or product that solves a popular problem.
In this case, DERA has come up with a way to combat email borne viruses. Realizing that you will not always be able to intercept and stop a virus as it makes it's way into the network, you can try to prevent it from "germinating" and spreading to other systems. This is a good idea, having defense in depth. If you don't catch incoming viruses at least you will be less likely to propagate them to other systems. Unfortunately, the method used by DERA is extremely simplistic and will no doubt annoy users to no end.
DERA's idea is that when you send out an email you will receive a message asking you if you really want to send it. Thus, viruses that generate emails to spread themselves will be stopped as the user will realize they have not intended to send a message, and they will not click OK...
