Is it true that wireless network users are themselves vulnerable to security breaches even when connected to a corporate LAN via a wireless VPN connection?
Yes, there are three primary ways at which wireless users are at risk. First, if volumes or folders on the users’ machines are shared, it is possible for other users within the subnet to access the contents of those shares. Second, someone on the same subnet as the user could perform a buffer overflow attack against the user. Finally, not all traffic is routed over the VPN. Traffic related to Internet usage is routed over the Internet. This traffic is subject to capture through the usual methods.
