OPSEC is a process for safeguarding Critical Information and Indicators (CII), whether classified or unclassified. Contractors must adhere to an OPSEC plan, which may require a signed document prior to the contract's start date, or simply an acknowledgment of these requirements. Contractors and subcontractors are responsible for preventing inadvertent disclosure of CII, which includes operational schedules, equipment details, and personally identifiable information (PII). Prohibited actions include publicizing CII in newsletters or on social media, transmitting it to personal email accounts, and taking unauthorized photographs or videos within shipyard work areas. The policy also addresses Portable Electronic Devices (PEDs), outlining restrictions on their use and requiring coordination with a sponsor for approval. Failure to comply can result in contract termination, removal of personnel, criminal prosecution, and civil penalties. Any unauthorized disclosure or compromise of CUI or other sensitive information must be immediately reported to the Activity Security Manager and Industrial Security Officer. Countermeasures include shredding sensitive documents, restricting verbal discussions about shipyard work, and immediately reporting lost or stolen badges.
