Most information that is classified is held at the secret sensitivity. c. Confidential – This is the lowest classification level of information obtained by the government. It is defined as information that would “damage” national security if publicly disclosed, again, without the proper authorization.

d. Public Trust – Certain positions which require access to sensitive information, but not information which is classified, must obtain this designation through a background check.
