 ## Witness is a pluggable framework for supply chain security
 
-Witness prevents tampering of build materials and verifies the integrity of the build process from source to target. It works by wrapping commands executed in a continuous integration process. Its attestation system is pluggable and offers support out of the box for most major CI and infrastructure providers. Verification of Witness metadata and a secure PKI distribution system will mitigate against many supply chain attack vectors and can be used as a framework for automated governance.

 ## Attestor Security Model
 
-Attestations are only as secure as the data that feeds them. Where possible cyrtographic material should be validated, evidence of validation should be included in the attestation for out-of-band validation.
