System of Records Notice (SORN)

A public notice describing a group of records containing personal information, including the purpose, routine uses, retention, and access procedures, required when records are retrieved by a personal identifier.

Related: Privacy Impact Assessment (PIA), Information Type
Supply Chain Risk Management

The process of identifying, assessing, and mitigating risks introduced by suppliers, products, and services across the acquisition life cycle, including counterfeits, tampering, and dependency on untrusted vendors.

Related: Risk Management Framework (RMF), Risk Response
Security Categorization

The process of determining the potential impact of a loss of confidentiality, integrity, and availability on organizational operations, assets, or individuals, producing a low, moderate, or high rating that drives baseline selection.

Related: FIPS 199, Control Baseline
FIPS 199

The federal standard that defines security categories based on the potential impact of compromising confidentiality, integrity, or availability and establishes the high-water mark rule for overall system categorization.

Related: Security Categorization, Control Baseline
System Boundary

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.

Related: Authorization Boundary, Interconnection
Authorization Boundary

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.

Related: System Boundary, Authorization Package
Interconnection

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.

Related: System Boundary, Authorization Boundary
Information Type

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.

Related: Security Categorization, Privacy Impact Assessment (PIA)
Mission/Business Owner

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.

Related: Authorizing Official (AO), Security Categorization
Control Baseline

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.

Related: Tailoring, Overlay
Tailoring

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.

Related: Control Baseline, Compensating Control
Overlay

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.

Related: Control Baseline, Tailoring
Compensating Control

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.

Related: Tailoring, Control Baseline
Common Control

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.

Related: Control Inheritance, Security Control Assessment
Control Inheritance

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.

Related: Common Control, System Security Plan (SSP)
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.

Related: Authorization Package, Control Inheritance
Security Control Implementation

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.

Related: Configuration Management, System Security Plan (SSP)
Configuration Management

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.

Related: Security Control Implementation, Continuous Monitoring
Security Control Assessment

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.

Related: Security Assessment Report (SAR), Assessment Method
Assessment Method

The technique used to gather evidence during a control assessment, typically examining documents, interviewing personnel, or testing mechanisms, chosen to match the control and the desired confidence level.

Related: Security Control Assessment, Security Assessment Report (SAR)
Security Assessment Report (SAR)

The deliverable that documents assessment findings, including control effectiveness, identified weaknesses, and the assessor's judgment about the system's security posture, supporting the authorization decision.
