What are some of the threats through VPNs?
What will be an ideal response?
Attacks on a company's network through a VPN are often indirect, and a result of successfully hacking a remote user's computer (or stealing a laptop). After successfully attacking the remote user's computer, the hacker can follow what that user does. If a VPN connection is sometimes used on the compromised computer, the hacker can acquire the necessary information and attempt to connect to the company network using the VPN connection. VPN connections are logged,but if the connection comes from a valid user and the passwords match, then the VPN server assumes the connection is valid.?A VPN connection of a valid user can be used to perform many attacks on a network, including DoS, session hijacking, and spoofing, as well as plain old theft, vandalism, and terrorism. Since the attacks are not considered a result of weaknesses in the VPN, they are deemed indirect attacks.
