Episode 16 — Harden User and Device Authentication Against Attacks
Strong authentication blocks a large share of real-world compromises and appears frequently on the SSCP exam. This episode clarifies the difference between identification, authentication, and authorization; distinguishes factors (something you know, have, are); and explains assurance concepts like resistance to phishing, replay, and credential stuffing. We compare passwords, passphrases, tokens, mobile authenticators, biometrics, and risk-adaptive methods, tying each to threats and usability constraints. You’ll learn how account lockouts, throttling, and monitoring reduce brute force success, why secure recovery flows matter as much as sign-in strength, and how device posture signals (health attestations, certificates, jailbreak detection) raise confidence that the requester is both the right person and using an acceptable endpoint.
We translate principles into patterns you can recognize under exam pressure. Examples include enforcing multifactor authentication on administrative consoles, binding tokens to specific devices, and using mutual TLS or device certificates to prevent credential reuse on unmanaged hardware. We cover defense-in-depth: credential vaulting, Just-In-Time privilege elevation, secure secrets storage, and session management with short lifetimes and refresh tokens. Troubleshooting topics include bypass-resistant recovery, protecting time-based codes from clock drift, preventing MFA fatigue attacks, and minimizing biometric spoofing risk with liveness detection. By the end, you’ll be able to select authentication measures that meet risk, verify effectiveness through logs and artifacts, and avoid common pitfalls that attackers routinely exploit.
