CORE DEFINITION

No matter how complex your encryption algorithm is (AES-256, RSA), as long as you beat the person holding the key with a rubber hose or threaten his family, he will tell you the password.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Find the short board outside the system. Technically perfect defenses often crumble in the face of human weaknesses in the physical world. When designing a security system (or any rules), you must consider the 'human' as the weakest link, i.e., social engineering attacks.

The weak link in an attack is often the 'human' rather than the algorithm—coercion to obtain keys reveals the fragility of technical defenses in the face of social engineering.
