What is Identity? Security Fundamentals

When you hand over a passport at a border, something deceptively simple happens: a system answers the question "who are you?" by checking a claim against a binding and verifying the result. That three-part process — claim, binding, verification — is the skeleton of identity in any system, physical or digital. But in a digital environment, none of the physical anchors exist. No body, no face, no presence. Just data. And that gap is where most identity attacks begin. In this video, we build a precise definition of identity from the ground up: a representation of a subject, built from attributes, meaningful only within a specific context. We look at why identity isn't a property of a person but a construct created by a system — which is why the same human can have entirely different identities in different systems, and why those identities have to be independently established and maintained. This distinction sounds subtle, but it has enormous consequences for how attacks work. This is the first video in series on Identity Security, covering everything from how identity is bound and verified, to the full range of attacks — impersonation, replay, downgrade, confusion, partial compromise, and what lingers long after a breach. Whether you're building systems, defending them, or just trying to understand how modern security actually works, this series starts here.
