PURPOSE OF SECURITY
The purpose of the Navys Security Program is to
ensure official information of the Department of the
Navy relating to national security is protected to the
extent and for a period of time as may be necessary.
The Department of the Navy Information and
Personnel Security Program Regulation establishes
the basis for the identification of information to be
protected; prescribes a progressive system for
classification, downgrading, and declassification;
prescribes safeguarding policies and procedures to be
followed; and sets up a monitoring system to ensure
the effectiveness of the program.
The Security Program basically deals with the
safeguarding of information that cannot be known or
made available to foreign governments or foreign
nationals because of the threat that such information
might be used to the detriment of the United States.
The security of the United States in general, and of
naval operations in particular, depends in part upon the
success attained in the safeguarding of classified
Information may be compromised through
careless talk, through actual subversion by enemy
agents, by careless handling of classified material, and
in various other ways.
