Security has been, is, and always will be a major concern in the Navy. Security is everyone's responsibility. You play an important part in your command's security program by protecting and safeguarding your computer hardware and software. Hardware Security

Your workspace normally provides sufficient physical security to protect against unauthorized access and theft of material. Where possible, access to spaces where computer hardware is stored and operated is restricted to authorized personnel only. If, at any time, unauthorized personnel require access to the area, ensure that proper safeguards are used to protect your equipment. At the completion of a normal workday or when your activity is not manned, ensure that all computer hardware is stored in a secure area to prevent access by unauthorized personnel.

Software Security

The primary storage location for information is the floppy disk. The disks that you normally use are not much more than 5 inches in diameter. Their small size makes them easily hidden. It is also easy for anyone to make copies of disks. All computer software must be given proper safeguard to prevent theft, loss, or destruction. The following actions are a partial list of security requirements:

0 Always attach an external label to all disks to reflect the security classification of the material on individual disks. See figure 1-15

0 Always, to limit access, store all disks in a classified container when they are not in use.

Always keep disks not in use in their protective envelopes and ensure that they are stored vertically in their storage boxes.

Remember, once you lose the information on a disk, it is unlikely that it can be retrieved. It usually

must be retyped. It is up to you to ensure the proper care and maintenance of all disks that you use to preclude any unwarranted problems.

PUBLICATIONS MAINTENANCE

You, as a Mineman, use many different publications that apply to your job. Now it is your job to ensure that these publications are properly maintained and updated and that a full allowance is on board in accordance with the mine bill of material (MBOM).

A publication may contain anything from the description of a weapons system to test procedures to a parts breakdown to information on ordering needed parts. Without proper maintenance of these publications, erroneous or outdated information could be used.

This section discusses publication changes and technical manual reports.
