I recently started at a new company, where the Cisco VPN Client is used by all remote Windows users. I am not familiar with the client. I see by our Remote Access Policy that the clients authenticate using PAP. This immediately drew my concern.
My question is does this present a security threat? Even though the auth is unencrypted, it is still happening within a 3DES IPSec tunnel, right? What is the best practice with regards to using the VPN client and authentication?
Thanks in advance!
Cisco VPN Client v5 (latest build) on Windows XP SP3
