Step-by-step explanation:
OPSEC, or Operations Security, is a comprehensive process designed to safeguard sensitive information by identifying and controlling indicators that adversaries might exploit. It is not merely a set of rules but a dynamic methodology that involves assessing potential threats, analyzing vulnerabilities, and implementing countermeasures. The goal of OPSEC is to deny adversaries access to critical information that could be exploited to compromise operational effectiveness.
Contrary to the option "Only applies to work and is not applicable to my personal life," OPSEC principles can be applied both professionally and personally to protect sensitive information in various contexts. It is a mindset and set of practices that should be integrated into daily activities to ensure the security of information across different aspects of life.
