SAFEGUARDING OFFICIAL INFORMATION IN THE INTERESTS OF THE
DEFENSE OF THE UNITED STATES
1. The President on 5 November 1953 signed Executive Order No. 10501
with title as given above. This Executive Order becomes effective 15 Decem-
ber 1953-
2. CIA Regulations are currently being rewritten to incorporate as
necessary the provisions of this Executive Order. In the interim, however,
it is considered desirable that all employees become familiar with this
Executive Order and that guidance be given concerning those provisions not
covered in existing Agency Regulations.
3. The following advice and instructions are given for CIA imple-
mentation on 15 December of those provisions of the Executive Order not
currently in CIA Regulations:
a. The words "Security Information" which previously followed
a security classification will no longer be used. Rubber stamps
presently in use which show a security classification and the words
"Security Information" can be changed by removal of the latter words
with a sharp knife or razor blades
b. Forms already printed and bearing the words "Security Infor-
mation" will not be released outside of CIA. Either these printed
forms will be overprinted. to strike out the words "Security Information",
or if this is not practicable, the words will be deleted by drawing
a pen line through them. Present stocks of forms will only be over-
printed, or destroyed and reprinted, upon the recommendation or with
the concurrence of the Printing Advisory Staff, General Services Office.
c. The security classification of RESTRICTED is abolished.
Material which is presently classified RESTRICTED "Security Informa-
tion" need not be reviewed at this time for the purpose of downgrading
or upgrading except when such material is to be transmitted outside
of the Agency.
d. The language of definitions of TOP SECRET, SECRET, and CONFI-
DENTIAL in the Executive Order differs in some respects from that used
in current CIA Regulations. However, in substantive intent, the defini-
tions are not dissimilar.

e. There will be established in the Office of the Assistant
Director for Collection and Dissemination the position of CIA Classi-
fication Control Officer who will provide general guidance to Office,
:Division and Staff Chiefs in carrying out the requirements of Executive
Order 10501. Each Chief of Office under the Deputy Director (Intelli-
gence) and the DeputyDirector (Administration), each Chief of Area
Division and Senior Staff under the Deputy Director (Plans), and the
Director of Training and the Assistant Director for Communications will:
(1) Designate sufficient persons by name or position as
having authority to classify original documents to insure the
orderly and expeditious transaction of business.
(2) Designate persons to be responsible for the continuing
review of classified material for the purpose of declassifying
or downgrading.
(3) Designate Assistant Classification Control Officers
who in consultation with the CIA Classification Control Officer
will assist responsible component heads in the continuing review
of the implementation of this Order.
f. The Director of Security will assist the CIA Classification
Control Officer with advice and guidance and in the conduct of training
and orientation programs. The Director of Security, together with the
CIA Classification Control Officer, will establish an active inspection
program to insure that the provisions of this Fecutive Order are being
carried out.
g. The use of an automatic downgrading paragraph or statement
will be used in correspondence and on documents whenever practicable;
e.g., after a specified event or date, or upon removal of classified
enclosures, the material will be downgraded or declassified. For
example:
(1) Regraded UNCLASSIFIED (Or appropriate classification)
when separated from classified enclosure.
(2) After 30 June (or appropriate date), this mem-
orandum is downgraded to
(3) When subject project becomes operational, these planning
papers are downgraded to

h. The present accountability system of logs, courier receipts,
and intra-office routing sheets used in the transmission of TOP SECRET,
SECRRET and CONFIDENTIAL documents within CIA is considered to offer an
equivalent degree of security to that required by the Executive Order
for transmission outside an agency.
i. TOP SEMET, SECRET, CONFIDENTIAL and Registered documents
of all classifications will continue to be stored in safes, safe files,
or vaults. RESTRICTED documents not registered, until such time as
they may be declassified, will be stored in metal file cabinets with
key locks or in safes.
