Level II
Level II data is unclassified data that requires special protection. Examples
are data For Official Use Only and data covered by The Privacy Act of 1974.
To assure protection for processing Level II data, the Navy established the
limited automated information system access security mode. A system or
network operating in the limited access security mode restricts the access to
data only to individuals who by their job function have a need to access the
data.
Level III
Level III does not require the safeguards of Level I or Level II data. It does
however, require proper handling to make sure that data is not lost or
destroyed.
Electronic
The computer system and its associated peripherals require controlling and
media
safeguarding at all times. This includes the disks, diskettes, disk drives,
monitors, printer ribbons, and generated hard copy. In general, the two
types of electronic media are working copy media and finished media.
WORKING COPY MEDIA: Working copy media is temporary information.
It stays within the confines and control of your activity. After creating a
working copy, retain it for 180 days before destruction. Examples of
working copy media are information used and updated at frequent intervals.
FINISHED MEDIA: Finished media is permanent information. It can be
released to other commands and activities. Finished media contains
information that does not change or is pertinent for more than 180 days.
Security
Date and mark classified electronic media when it is created. Control
controls
electronic media in the same manner prescribed for classified material.
Protect working copy media according to the highest classification ever
recorded on the media. For media classified Top Secret or Secret, maintain a
master list including the overall security classification and the identification
