Security
Introduction
DMs often work on classified or sensitive data. Graphics and text created
electronically and stored on disks require protection. The procedures for
protecting and marking disks, disk drives, and workstations differ slightly
from what you are familiar with for hard copy data. Security procedures for
electronic data is found in the Department of the Navy ADP Security Manual,
OPNAVINST 5239.1.
Automated
data processing
security officer
(ADPSO)
Your command will have an automated data processing security officer
(ADPSO) that reports to the commanding officer concerning the protection of
electronically generated data. The ADPSO is responsible for the physical
security of each computer workstation. The protection of each workstation
involves physical security, physical access control, data file protection, and
natural disaster protection. Seek out your ADPSO and make sure your
workstation complies with Navy and command regulations for the protection
of classified material.
Security
The three levels of data processed electronically are Level I, Level II, and
Level III. If your command processes Level I and/or Level II data, it must
provide a specific degree of protection. The following table defines the three
levels of data:
