The Plain Language Guide to Online Operational Security (OPSEC)

Operational security is not a list of tools. It is a way of thinking. This guide teaches how to analyze your own situation, identify your actual risks, and make informed decisions about what to protect and how — rather than applying one-size-fits-all advice that may not match your circumstances.

Covers threat modelling, compartmentalization, identity separation, communication security, metadata awareness, and the operational practices that determine whether your technical privacy setup actually works. The tools mean nothing if the operational habits around them are careless.

This guide bridges the gap between having privacy tools installed and actually using them effectively. The technical setup is only half the picture. This is the other half.

What this guide covers

• Threat modelling — understanding your actual risks, not theoretical ones
• Compartmentalization — separating identities, devices, and activities
• Metadata — what it reveals and how to minimize it
• Communication security habits that protect what the tools cannot
• Identity separation — keeping different areas of your life isolated
• Common mistakes that undermine otherwise good technical setups
• Written from years of living inside a serious operational security setup

Who this guide is for

Anyone who wants to understand this subject properly — not just follow instructions without knowing why. Whether starting from zero or with some familiarity, this guide builds a solid foundation through real understanding.
