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