Workload Security verifies the signature on the agent to ensure that the software files have not changed since the time of signing. An integrity check occurs when:
  1. You are upgrading the agent.
  2. You are enabling a new security module so the kernel support is being updated. If the validation fails, plugin installations and agent upgrades are blocked.
