TOP SECRET CONTROL LOG

Upon receipt of a Top Secret message, including SPECAT SIOP-ESI, addressed to the parent command or subscriber of the message center, the center assigns a sequential number and enters the originator, DTG, and copy count of the message into the Top Secret Control Log. A separate entry is made for each addressee. The messages must be annotated as "Copy ___ of ___" and "Page ___ of ___." The message must also be assigned a Top Secret control sequential number.

CIRCUIT LOGS

Records of messages sent via ship-shore circuits, whether primary shipshore, full-period termination, and soon, must be maintained. This ensures continuity of traffic, accurate times of delivery/receipt, and precise files for possible tracer action. These actions should be recorded on the Received Message Record, OPNAV

Figure 2-5.-Central Message Log for outgoing and incoming messages.

Figure 2-6.-Received Message Record, OPNAV Form 2110-15.

Form 2110-15 (figure 2-6). Although this form is primarily designed as a record of received messages, only a pen-and-ink change is necessary for its use as a send log.

JOURNAL LOGS

In most automated systems, all significant system events are entered in a journal log. This log is a chronological record of data processing operations, which may be used to reconstruct a previous or updated version of a file.

All system-level commands entered by an operator are logged. Log entries are usually queued for delivery to a printer as they are generated, but this is optional. However, they are always journaled to a file from which they can be recalled and printed at a later time, as desired. This log gives a system operator or supervisor the ability to review current and previous system events.

In addition, the journal log supports message accountability. The system records the receipt of every formal message and the termination of every formal message delivery that it schedules.
