What is SAML and how does SAML Authentication Work?

This article explains the “harvest now, decrypt later” risk—adversaries collecting encrypted data today for future quantum decryption—highlighting tactics like lateral movement, passive MITM, and stealthy exfiltration of long-retention archives. It urges immediate preparation through post-quantum cryptography (ML-KEM/ML-DSA), hybrid encryption, SASE-based inspection with quantum-resistant tunnels, zero trust and micro-segmentation, data minimization, and AI-driven policy, authentication, threat hunting, and automated response, prioritizing crypto inventories and protection of long-lifetime data in high-risk sectors such as government, healthcare, and critical infrastructure.
