What Cisco NAC does is monitor what systems are on the network and what they are running. The reason NIU provides for using Cisco NAC is that:
"In the past, due to the impact of viruses and worms on the NIU network:
- The resources at the ResTech Helpdesk were stretched to the limit by the sheer volume of infected computers that needed disinfecting
- Viruses destroyed information on student computers and compromised other computers on the NIU network
- Hundreds of residents’ computers have been so severely infected that they have been removed from the network for days or even weeks"
- Microsoft Critical Updates
- AntiVirus Software Installed
- AntiVirus Definitions
- Enable Windows firewall and Automatic Updates
Now I would like to share a lesson with you that I have been taught a few times by this point in my life.
In case you didn't follow the link I provided earlier the very next line after all that mumbo-jumbo about Windows is:
Thats it. Just a web login. No anti-virus, no update monitoring, no mandatory firewall, no big-brother type behavior of any sort. To quote my friend "I guess they believe that linux machines behave well enough that they don't need big brother".
That there is even a mention of Linux on a page such as this reminds me of the fact that regardless of what people think the OS market shares are - there are obviously enough Linux users out there to provide support to them.
What about you? Ever found support for your operating system from somewhere you weren't expecting to find it?
