Based on different threat levels I think it's prudent and realistic to examine different staffing strategies, different views of alarms and datas, potentially different reactions, engaging LEA's on issues you may not normally engage on, etc. Example: DHS sets RED level. Reaction: Move some third level engineers into the SOC. Audit the DR plan if it's not on schedule to be audited. Audit the backup plans if not on schedule to be audited.

I'd like to have a more standard application to risk analysis. As you know, security policy is always reviewed and risk analysis applied to determine how and what you are going to protect. Or not protect. I think these risk analysis' are now affected by these "new" threats, or in a lot of cases, threates that noone really paid much attention to before. > > I'd take it serious and consider NBC as well as "cyberAttacks". > > Secretary Ridge has said to keep the plastic sheets and duct tape in > storage.

Secretary Ridge hasn't really established a credibility level. Not yet anyways. I respect what they are doing and understand they need time, but we all have businesses to run. If he says "Buy plastic and duct tape" I take that as he knows something we don't and it's reasonable to evaluate and re apply the risk analysis. I have my duct tape and plastic, but haven't applied it to the windows.
