OpSec
Operational security, commonly abbreviated OpSec, is a systematic discipline used to identify information that, if exposed, could compromise an operation. It requires assessing the threats and vulnerabilities surrounding that information and applying countermeasures to reduce the risk of disclosure or misuse. The aim is to protect mission effectiveness, safety, and competitive position by limiting what is revealed and to whom.
OpSec originated in military intelligence practices and was formalized by modern security doctrine in the late
Core concepts include identifying critical information, understanding potential threats, assessing vulnerabilities, and evaluating risk. Countermeasures are
The typical OpSec process is iterative and commonly described as six steps: identify critical information; analyze
Practices span both physical and digital domains. They commonly involve data minimization, need-to-know access, secure communications
Limitations: OpSec cannot guarantee absolute security and depends on people, processes, and technology. It requires ongoing
