Identity-based authentication alone is insufficient to stop modern attacks like session token theft via adversary-in-the-middle phishing kits. Even after MFA succeeds, attackers can hijack sessions using stolen cookies that are indistinguishable from legitimate ones. NIST SP 800-207 (Zero Trust) calls for continuous device posture verification, not just one-time login checks. Most Zero Trust implementations remain identity-centric, leaving device health inconsistently enforced. A stronger model continuously verifies both user identity and device health throughout a session, binds access to approved hardware, applies proportionate enforcement, and enables self-service remediation for posture issues.
