On his PC, he has a VPN link to one of our partner's systems (warranty system). He wants to have MSN messenger on his PC through a dedicated port so it allows only text messages. I'm worried about security implications since this will allow his PC to have a direct link to the Internet without going through our firewall or proxy. Is there a safe way to satisfy this need without the risk, or is it risky enough to reject his request?
I understand your concerns. MSN Messenger, as well as other instant messenger services, could open security holes. If there isn't a pressing business need, I always block them. However, sometimes users actually require these services for business purposes. I'd make sure that he has a personal firewall (such as Zone Alarm or BlackICE) and an antivirus program on his computer. Also, he should keep his system patched, running the Windows Update feature on a regular (say weekly) basis. That should mitigate much of the risk.
