Title

Outlook Dial-up options to Warn user before allowing switch in dial-up access must be configured. (Cat II impact)

Discussion

Users can connect to their e-mail servers using dial-up networking if their accounts are configured appropriately. Dial-up connections are often used by mobile users who need to connect to the Internet from remote locations. Remote connections are generally not subject to the same restrictions as enterprise network environments, which can make them more vulnerable to attack.
