Which of the following is not a security benefit of Immutable workloads?

Performing security testing during image creation is a genuine benefit because vulnerabilities are caught before deployment into production.

Eliminating the need to patch running systems removes a major attack vector and operational risk, making this a true security benefit.

Immutable workloads are designed so that no changes are made to running instances - they are replaced rather than modified. Enabling remote logins (such as SSH) to running workloads directly violates this model by creating a pathway for unauthorized or untracked changes, introducing configuration drift and expanding the attack surface. This negates the core security guarantee of immutability.

Faster rollout of updated versions allows security fixes to be deployed rapidly, which is a security benefit of the immutable model.

Disabling unnecessary services and whitelisting applications during image creation reduces the attack surface, which is a recognized security benefit.
