Extent of Government Computers Infected By Bots Uncertain
Krishna Dagli writes to mention findings by the company Trend Micro on the extent of bot infection in U.S. Government computers. The article by Information Week indicates that, while the 'original' findings were much harsher, the security vendor has since backed down from some of its claims. Still, the extent to which information-stealing software has penetrated our national infrastructure is enough to take note. From the article: "While it may be tempting to discount the warnings of security vendors as self serving--bot fever means more business for Trend Micro--there's unanimity about the growing risk of cybercrime. In its list of the top 10 computer security developments to watch for in 2007, released last week, the SANS Institute warns that targeted attacks will become more prevalent, particularly against government agencies. 'Targeted cyber attacks by nation states against U.S. government systems over the past three years have been enormously successful, demonstrating the failure of federal cyber security activities,' SANS director of research Alan Paller says in an e-mail. 'Other antagonistic nations and terrorist groups, aware of the vulnerabilities, will radically expand the number of attacks.'"
If an Agency is willing to spend the money, time and energy to put in place the protections that the typical Government information system deserves, this wouldn't be a problem.
My agency uses a multi layered defense to protect us against these issues. There are network level protections, PC level protections and desk-side support level protections. We also regularly send out warnings about current threats as well as require personnel to undergo annual IT security awareness training.
Individual PCs that are found to be broadcasting unknown signals to unknown or unverifiable outside destinations are removed from the network and reimaged immediately.
If, from a complaint to the help line, we find that a PC is infected with spyware, we don't even try to remove it; it is immediately reimaged.
We have instituted a locked down desktop policy; users are NOT allowed admin access except through application to a special committee for good business cases, based upon the use of special software that requires such access to run. We bend over backwards to alter those situations to avoid that access whenever possible.
Laptops are imaged using an image that is encrypted using a good encryption program that encrypts the entire hard drive using a 512 bit key, and NO laptops are allowed to be bought without going through our recieving process where that image is installed.
We have spent millions of dollars of your tax money in the last five years bringing this system online, but now that we have, we believe that we have as safe a system that we can get without just unplugging it or spending twice as much.
We don't have classified material, but we do have information that is confidential by law and must be protected from public release. (proprietary information belonging to firms we regulate.) This limits the measures we need to use, since classified material requires a completely different level of protection.
If the VA had used a system like ours, they would never have been embarrassed by the recent theft. The theft may still have occurred, but the information would never have been at risk.
It is not a perfect system, and it takes constant dilligence to maintain and periodically upgrade, but I think we do a pretty good job.
