Call-Back Verification

Call-Back Verification definition - hacker
A security feature enabling a host to not only disconnect a remote caller after a positive connection but also recall the remote computer, usually for security verification. Call-backs are typically limited to previously stored telephone numbers, thus enabling connection only for authorized usage.

This technology is used to effectively block an attack path in which a cracker dials in to an organizationÂ’s Remote Access Service provided for legitimate organizational users and gains access by using a stolen or guessed username/password combination.
