OpSEC is all about hiding information from your adversaries: those who have resources and those who dont. The first group comprises intelligence agencies, military organizations and the big bad boys. The second contains the rest: no resources is not the same as no danger, but they are less able to track you unless you give away information for free. The tips are focused on encounters with the first group, since that is more likely to happen. Be prepared in advance for situations where we are more vulnerable.”]
