===Physical Security Policies===
 
The physical security program at NSA provides protection for
classified material and operations and ensures that only persons
authorized access to the Agency's spaces and classified material are
permitted such access.  This program is concerned not only with the
Agency's physical plant and facilities, but also with the internal
and external procedures for safeguarding the Agency's classified
material and activities.  Therefore, physical security safeguards
include Security Protective Officers, fences, concrete barriers,
access control points, identification badges, safes, and the
compartmentalization of physical spaces.  While any one of these
safeguards represents only a delay factor against attempts to gain
unauthorized access to NSA spaces and material, the total combination
of all these safeguards represents a formidable barrier against
physical penetration of NSA.  Working together with personnel
security policies, they provide "security in depth."
 
The physical security program depends on interlocking procedures.
The responsibility for carrying out many of these procedures rests
with the individual.  This means you, and every person employed by,
assign, or detailed to the Agency, must assume the responsibility for
protecting classified material.  Included in your responsibilities
are:  challenging visitors in operational areas; determining
"need-to-know;" limiting classified conversations to approved areas;
following established locking and checking procedures; properly using
the secure and non-secure telephone systems; correctly wrapping and
packaging classified data for transmittal; and placing classified
waste in burn bags.
