The documented set of components, users, data flows, and interfaces that a categorization and authorization effort treats as the system under consideration, distinguishing inside elements from the environment.
- Authorization Boundary
- Related: System Boundary, Authorization Package
The specific scope of components, applications, and data covered by a single authorization decision, which may include multiple systems and is defined by the authorizing official and system owner.
- Interconnection
- Related: System Boundary, Authorization Boundary
A direct connection between two systems that allows data exchange, requiring documented agreements, security controls at the interface, and approval from the authorizing officials of both parties.
- Information Type
- Related: Security Categorization, Privacy Impact Assessment (PIA)
A category of information with common characteristics, such as protected health information or financial records, used to identify privacy and security requirements that flow down to the systems that process it.
- Mission/Business Owner
- Related: Authorizing Official (AO), Security Categorization
The official accountable for a mission or business process supported by a system, who defines requirements, accepts residual risk at the process level, and participates in categorization and authorization decisions.
- Control Baseline
- Related: Tailoring, Overlay
A pre-defined set of security and privacy controls for a given impact level, drawn from a catalog, which serves as the starting point for tailoring to the system's specific mission, environment, and risk.
- Tailoring
- Related: Control Baseline, Compensating Control
The process of adjusting a control baseline by adding, removing, or compensating for controls to reflect the system's specific characteristics, mission needs, and environment of operation, with documented rationale.
- Overlay
- Related: Control Baseline, Tailoring
A set of control modifications applied on top of a baseline to address a specific community, technology, or mission context, such as cloud, industrial control systems, or privacy-specific requirements.
- Compensating Control
- Related: Tailoring, Control Baseline
An alternative control used when a required baseline control cannot be applied as written, providing equivalent or greater protection and requiring documented justification and approval.
- Common Control
- Related: Control Inheritance, Security Control Assessment
A security or privacy control implemented by an organization and inherited by multiple systems, reducing duplication and requiring documented responsibility between the provider and consuming systems.
- Control Inheritance
- Related: Common Control, System Security Plan (SSP)
The transfer of responsibility for a control's implementation and assessment from a providing entity to consuming systems, documented so that each system's security plan reflects actual coverage.
- System Security Plan (SSP)

The document describing a system's boundary, categorization, controls, implementation details, and responsibilities, serving as the primary record of how the system meets its security and privacy requirements.
- Security Control Implementation
- Related: Configuration Management, System Security Plan (SSP)
The actual deployment and configuration of selected controls in a system's environment, including technical settings, procedures, and assigned responsibilities, which must match what the security plan claims.
- Configuration Management
- Related: Security Control Implementation, Continuous Monitoring
The disciplined process of identifying, controlling, and auditing changes to system components and settings so that implemented controls remain effective and unauthorized changes are detected and reversed.
- Security Control Assessment
- Related: Security Assessment Report (SAR), Assessment Method
An independent evaluation of whether controls are implemented correctly, operating as intended, and producing the desired outcome, using examination, interview, and testing methods against defined assessment objectives.
- Assessment Method
