What is an example of a vulnerability in terms of OPSEC?

In the context of Operational Security (OPSEC), vulnerabilities can be defined as weaknesses that could be exploited by adversaries to gain unauthorized access to sensitive information. Non-secure communication is a prime example of such a vulnerability because it does not utilize protective measures to secure the data being transmitted. This lack of security can lead to eavesdropping, interception of critical information, and potential exploitation by hostile entities.

In contrast, secure communication protocols, regular training sessions, and limited access to information are considered protective measures or practices that enhance security rather than expose vulnerabilities. Secure communication protocols are designed to safeguard data integrity and confidentiality, regular training ensures that personnel are aware of security practices, and limited access ensures that only authorized individuals can view sensitive information, all of which mitigate risk rather than contribute to it. Consequently, non-secure communication clearly stands out as a vulnerability in OPSEC, highlighting the importance of employing adequate measures to protect sensitive information from unauthorized exposure.
