A contactless key card and a hand-geometry scan

Symantec Corp. does its network security monitoring behind the locked doors of a nondescript office building in Alexandria, Va.

The building's diesel generators are capable of supplying all of its electrical needs during an outage, even in summer when the air conditioning is working hard.

Access is controlled by two-factor authentication.

A contactless key card and a hand-geometry scan are required to get into the so-called mantrap, a kind of air lock between the outside world and the security operations center. The outside door of the trap must be closed before someone can pass through the inner door into the operations center.
