Are there any projects to provide NAC support in Linux? My main aim is to accept/deny access to other network on a Linux Firewall after asking the operating systems' NAC agents about the client's health.
For example: if the client has no antivirus installed, this Linux will block the client's traffic.
Some switches have such capabilities. Is it possible in Linux?
It sounds like you are looking for packetfence... it runs under Linux...
You need to use packetfence + nessus (nessus wikipedia article) to enforce anti-virus policy
