-This use case outlines the process of building, signing, and verifying artifacts and images within the Zero Trust Validated Pattern (ZTVP) using the Red{nbsp}Hat Trusted Artifact Signer (RHTAS) and the Red{nbsp}Hat Trusted Profile Analyzer (RHTPA).
+A key objective of ZTVP is the comprehensive security of both the platform and the applications deployed on it. This use case outlines the process of building, signing, and verifying artifacts and images within the Zero Trust Validated Pattern (ZTVP) using the Red{nbsp}Hat Trusted Artifact Signer (RHTAS) and the Red{nbsp}Hat Trusted Profile Analyzer (RHTPA). Through the implementation of this supply chain, we can establish a chain of trust and integrity for applications.
