Locking the window won't help if the door is wide open. In OPSEC, always start with the basics, and only after should you move on to the little things.

What is OPSEC?

Operations security (OPSEC) is a process that identifies critical information to determine whether friendly actions can be observed by enemy intelligence, determines if information obtained by adversaries could be interpreted to be useful to them, and then executes selected measures that eliminate or reduce adversary exploitation of friendly critical information.

In simpler terms, it is the process of finding vulnerabilities that an adversary could exploit and patching them, thereby reducing your attack surface.

OPSEC is NOT a synonym for cybersecurity. It can encompass it; however, it also revolves around physical security.
