OPSEC stands for and why is it important?

• A. Operational Safety; it protects people from injuries.
• B. Open Security; it protects sensitive information.
• C. Operations Security; it protects sensitive information from adversaries.
• D. Organizational Security; it manages access to facilities.

Answer: (C)

OPSEC is Operations Security, a disciplined process that aims to protect sensitive information from adversaries by identifying what information could be valuable, how it could be exploited, and then putting countermeasures in place to reduce that risk. The idea is to look at two main parts: what needs protection (critical information) and how an opponent might obtain it (threats and vulnerabilities), followed by steps to minimize exposure.

This matters because if an enemy learns details about schedules, locations, capabilities, or plans, they can use that information to disrupt operations, cause harm, or gain unfair advantage. OPSEC isn’t just about physical safety or access controls; it’s about controlling what is shared and how it’s shared so that sensitive information doesn’t reach the wrong eyes.

The correct option captures the true focus: safeguarding sensitive information from adversaries. Other phrases like Operational Safety, Open Security, or Organizational Security don’t pinpoint the same objective of protecting information from those who would misuse it, so they don’t fit as precisely.
