such as “This page is unclassified” or “This page is
Confidential” is used.
When a change is being issued to an existing
classified publication, the changed pages will be
marked as if they were already entered into the basic
publication. If any of the changes is on an interior
page, it will be marked in the same way as the interior
pages of the basic publication.
Portion Markings
Each section, part, paragraph, or subparagraph of
a classified document will be marked to show its level
of classification or the fact that it is unclassified. The
reason for this requirement is to eliminate any doubt
as to which portion of the document contains, or can
reveal, information requiring protection. The
appropriate symbol will be placed immediately
following a portion letter or number, or in the absence
of letters or numbers, immediately before the
beginning of the portion. The symbols are as follows:
Top Secret (TS)
Secret (S)
Confidential (C)
For Official Use Only (FOUO)
Unclassified (U)
In addition to the classification symbols, the
following symbols may also be used:
Restricted Data (S-RD)
Formerly Restricted Data (S-FRD)
Critical Nuclear Weapons Design Information
(S-RD) (N)
When a major numbered or lettered paragraph and
all of its subparagraphs are unclassified, each
paragraph need not be marked. Marking the lead-in
paragraph with a (U) is sufficient.
The full classification—not the abbreviated
form—is marked on figures, tables, graphs, charts,
and so forth. The classification marking must be
centered just below the illustration. Special situations
may dictate the placement of the markings above or
actually within the general area of the illustration. The
important point is that the reader understand the
classification level of that illustration.
COMPROMISES AND SECURITY
VIOLATIONS
LEARNING OBJECTIVES: Define compromises
and security violations. List some of the
reasons that lead to compromises and security
violations.
There are two types of security violations: Those
that result in a confirmed compromise or possible
compromise of classified information, and those that do
not but in which a security regulation has been violated.
Compromise is the disclosure of classified
information to a person who is not authorized access.
The unauthorized disclosure may have occurred
knowingly, willfully, or through negligence.
The compromise of classified information
presents a threat to national security. The seriousness
of the threat must be determined and action taken to
reduce the effects of compromise. At the same time,
action must be taken to investigate the circumstances
and determine the causes, to prevent recurrence.
Compromise of classified material results when a
security violation has resulted in confirmed or
suspected exposure of classified information or
material to an unauthorized person. The compromise
is considered “confirmed” when conclusive evidence
exists that classified material was compromised; it is
considered “suspected” when some evidence exists
that classified material has been subjected to
compromise.
Any individual in the DON who is aware of the
compromise or possible compromise of classified
material must report the facts immediately to the most
readily available command.
Individuals who are aware of possible acts of
sabotage, espionage, deliberate compromise, or other
subversive activities must report immediately all
available information to the most readily available
command, which, in turn, will notify the appropriate
Naval Investigative Service office.
SECURITY CLEARANCES
LEARNING OBJECTIVES: Explain the
purpose of security clearances. List and explain
the types of BI done on an individual requiring
a security clearance.
