If you live in the USA, did you know that your tax dollars are being used for some really good purposes?
You better believe it. For example, the NSA provides some great guides and tools for securing your operating system, whether your are on a Mac, or running Windows, Linux, or Solaris.
Some of the guides can get a little complex (especially the Linux and Solaris ones), but even if you do some of what they suggest, you are increasing the security of your OS and are likely to learn a few things at the same time.
There are more resources from other parts of the government as well.
If you think you have been the victim of a cyber-crime, check out cybercrime.gov, where you can find courses of action to take and report what has happened to you.
A great place to keep an eye on the latest security trends, news, and vulnerabilities is the United States Computer Emergency Readiness Team (US-CERT) site. If the jargon seems confusing to you, they offer a version of the site for Luddites, written out in layman’s terms here.
If technical jargon turns you on, then by all means check out the National Institute of Standards and Technology’s Computer Security Division (NIST), where you can find a bunch of resources.
