Deployment Security

This section controls image verification and vulnerability enforcement.

Administrators can enforce security policies such as:

Allowing only signed images

Two image signature verification mechanisms are there, cosign and Notation. If enabled, only signed images can be deployed. It ensures image integrity and authenticity.

Preventing the use of vulnerable images

If 'Prevent vulnerable images from running' is enabled, Satama blocks deployment of images that contain vulnerabilities above a selected severity level.

You can adjust severity threshold from dropdown. If 'Low' vulnerability severity is selected, that means if any vulnerability (Low, Medium, High, Critical) exists, deployment can be blocked.
