Attachment 1 - Enclosure 2 PNSY OPSEC.pdf

This document is a Portsmouth Naval Shipyard Operations Security (OPSEC) Contract Requirements form that outlines critical information protection and security guidelines for contractors working with the facility. The document defines OPSEC as a process to protect sensitive and critical information from unauthorized disclosure, whether classified or unclassified, and specifies contractor responsibilities for safeguarding information during the contract period.

Key requirements include avoiding inadvertent disclosure of sensitive information, protecting Controlled Unclassified Information (CUI), and implementing strict guidelines for handling portable electronic devices. Contractors must not publicize government critical information in corporate communications, social media, or public websites, and are warned that disclosure or compromise of sensitive information could result in criminal prosecution. The document also provides a detailed list of critical information indicators and corresponding countermeasures, such as not posting shipyard-related information on public social media and properly destroying sensitive documents using an approved NSA crosscut shredder.
