Re: ND4SPD, NDD and any network gurus
This is a multi-level problem. Yes, home users are usually retarded when it comes to IT security. By just offering them free antivirus is not going to fix that.
However, providing licenses to users is a huge step in the right direction, if people are doing work at home and bringing data back in. Johnny already mentioned that DoD provides free Antivirus licenses to any user that has a computer at home. Many large corporations do this as well. If you are a large company, you have a lot of pull with these vendors. Have Symantec come in, tell them that you want to include free licenses for your employees at home, or you are going to switch to a different vendor. They would rather give away a small amount of revenue than lose that huge corporate account and the yearly maintenance fees that go along with it.
Another alternative is to employ nazi-strict network access control, with policy based network autorization. This ensures that every machine plugged in to your network has anti-virus with the latest signatures, and whatever patches you deem required. This would ensure that all end user machines at your company have anti-virus software installed, that would scan all of the infected files your users bring in from home. However, that will cost much more that just giving your users free anti-virus. It does, however, provide a much stronger form of integrated security.
OK... long rant is over. If you have any specific questions, just ask.
