Cisco Working to Block Viruses at the Router

macmouse writes "The San Francisco Chronicle has an article about Cisco and Anti-Virus companies working together to block viruses at the ISP (Router) level. It sounds like they will be using traffic shaping to block malicious traffic. Looking at it in an negative light however, it might mean that your required to have anti-virus software installed in order to use the internet. This can be a *big* problem for *nix/mac users which normally don't need or use AV software. Not to mention, being forced to purchase software from 'company x,y or z' in order to get online, regardless of platform. Hopefully, this is not going to happen."

nmap on a router?

[x-router]

I think what they are 'trying' to say is the the router itself will scan your machine in a nmap way to see if it can find problems.

If it finds issues then it will drop you from the network or block that port / problem.

Rather than check if you have the latest version of norton installed..but perhaps I read it wrong?

Implications?

Does this mean that I can't talk about viruses using code-samples over the internet? I can't download and study exploits anymore? If there is any possibility to encode the virus-code to circumvent the filter, then the virus can possibly do the same...

We kinda do this at Rutgers

We sort of do this at Rutgers University This summer was absolutely crazy for the network, due to all the worms and such. A new policy was instituted which requires users to visit a website which checks their operating system. If they're running Windows, they are *required* to download a scanner that checks for the relevant worms and installs Anti-Virus software. Users running alternative operating systems are completely exempt. It just says "There are currently no additional requirements for running Linux on the residential network." We've just begun shutting people off who fail to comply with the policy. I, for one, like it. However, the routers start to get overloaded if they have too many access control lists because they have trouble running them on the ASICs. So, they have to run in software mode, which starts to slow things down.
