Congress is working on yet another way to "enhance homeland security, including domestic preparedness and collective response to terrorism." This time by passing HR 6423, which seems to give the Department of Homeland Security the power to regulate anything that might be considered part of the US's critical infrastructure, which can pretty much include any computer in the entire country. This bill has the working title "Homeland Security Cyber and Physical Infrastructure Protection Act of 2010."
This is one of the worst ideas that I've seen in a while. The US government doesn't actually do a very good job of protecting its own IT systems very well, and it seems to me that there's a good chance that DHS would just extend the existing government security standards to cover the rest of the country instead of writing new ones. Ones that might actually make sense.
On the bright side, as the bill's web page tells us:
This bill is in the first step in the legislative process. Introduced bills and resolutions first go to committees that deliberate, investigate, and revise them before they go to general debate. The majority of bills and resolutions never make it out of committee.
so that there's probably a very small chance that this bill will ever become an actual law.
