Zero Knowledge Proof (ZKP)
ZKP: cryptographic method allowing one party to prove knowledge of a fact without revealing the fact itself, enhancing security and privacy in transactions, authentication, and blockchain protocols.

Zero Trust Architecture (ZTA)
Zero Trust Architecture: Security model assuming breach; verify users/devices before access. No default trust; continuous verification, segmentation, least privilege access. Focus on data protection and risk management.
Zero Trust Network Access (ZTNA)
ZTNA: Security model ensuring access control based on user identity. No trust by default; verifies each request regardless of location. Enforces least privilege, enhances endpoint security, and mitigates risks from breaches.
