(From the NSA Handbook)
Because of the potential security or safety hazards, certain items are
prohibited under normal circumstances from being brought into or removed from
any NSA installation. These items have been grouped into two general classes.
Class I prohibited items are those which constitute a threat to the safety and
security of NSA/CSS personnel and facilities. Items in this category include:
Prescribed electronic medical equipment is normally not prohibited, but
requires coordination with the Physical Security Division (M51) prior to being
brought into any NSA building.
Class II prohibited items are those owned by the government or contractors
which constitute a threat to physical, technical, or TEMPEST security.
Approval by designated organizational officials is required before these items
can be brought into or removed from NSA facilities. Examples are:
- Transmitting and receiving equipment
- Recording equipment and media
- Telephone equipment and attachments
- Computing devices and terminals
- Photographic equipment and film
A more detailed listing of examples of Prohibited Items may be obtained from
your Staff Security Officer or the Physical Security Division (M51).
Additionally, you may realize that other seemingly innocuous items are also
restricted and should not be brought into any NSA facility. Some of these
items pose a technical threat; others must be treated as restricted since a
visual inspection does not readily reveal whether they are classified. These
