Authorization Decisions

Source: NIST SP 800-37 R2

Systems and common security controls shall be authorized before being put into operations. According to NIST SP 800-37 R2, there are four types of authorization decisions that can be rendered by authorizing officials:

  • Authorization to operate
  • Common control authorization
  • Authorization to use
  • Denial of authorization

Ongoing authorization is not an authorization decision. It is a risk-based decision process of determining whether or not to accept the risk of continual system authorization to operate. It typically leverages the security and privacy information generated by the continuous monitoring program.
