a. Initial Notification. Any DDN user (person/department/agency) having knowledge of a suspected network security violation must contact the appropriate Defense Communications Agency OC/ACOC (Operations Center/Area Communications Operations Center) MILNET Monitoring Center to report the violation. If possible, reporting should be via secure means.

Secure and commercial telephone numbers to DCA Operations Centers are:

• What is caller's name and phone number
• Where is caller calling from (organization)
• Where is caller calling from (city & state)
• What is the caller's DDN network address

• When did the violation occur
• What happened
• How did the violation occur (if known)
• What damage was done
• What has the subscriber done about the violation

(3) Anything else the caller wishes to report

Once a suspected violation is reported and the above information collected, the PACIFIC and EUROPEAN ACOCs will immediately relay this information back to the DCAOC (WESTHEM/CONUS) for action.

b. Follow-on Network Information via the Security Coordination Center. DCA, through direction provided by the DDN Network Security Officer (NSO), will provide rapid and reliable follow-on information on security exposures, fixes, and concerns via the SCC. Distribution of information is accomplished via DDN Security Bulletins. Network security and management personnel are encouraged to pay close attention to these bulletins as they may be of great assistance either in preventing network security problems or in solving existing problems. DDN Security Bulletins will be published on as "as needed" basis.
