Which event might compromise OPSEC?

• A. Scheduled maintenance of equipment
• B. Publicizing future operations without security precautions
• C. Inter-departmental meetings with secure access
• D. In-house training sessions

Answer: (B)

Publicizing future operations without security precautions is a significant threat to Operational Security (OPSEC). OPSEC is a process that helps protect sensitive information from adversaries by identifying critical information and implementing measures to safeguard it. When future operations are made public without adequate security measures, it can provide potential adversaries with insights into plans, resources, and strategies, enabling them to interfere or counteract those operations effectively.

This breach can lead to increased risks, including the exposure of sensitive techniques, tactics, and procedures, ultimately compromising the operational effectiveness of an organization. OPSEC relies on the principle of not revealing information that could be exploited, so failing to manage such disclosures directly undermines the entire purpose of the OPSEC framework.

The other options, while they may involve aspects of security or operations, do not inherently compromise OPSEC in the same way. Scheduled maintenance of equipment is typically planned with security in mind, inter-departmental meetings with secure access are designed to protect sensitive discussions, and in-house training sessions usually focus on enhancing security awareness and protocols.
