Agent package integrity check

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.
