The level of exposure an activity would carry if no controls were in place, used as a baseline for judging whether controls are proportionate.

Key Risk Indicator

A forward-looking metric with defined thresholds that signals whether a risk is increasing or decreasing, enabling early intervention before losses occur.

Control Effectiveness

An assessment of whether a control is designed appropriately and operating as intended, usually evidenced by testing, sampling, or continuous monitoring data.

Related: Inherent Risk, Residual Risk
Three Lines Model

A governance structure separating operational management, independent risk and compliance functions, and internal audit, each with distinct assurance responsibilities.

Related: Security Governance, Control Effectiveness
Regulatory Mapping

The practice of aligning internal controls to multiple external obligations so one control set can evidence compliance with several regulations simultaneously.

Related: Compliance Obligation Register, Control Effectiveness
Compliance Obligation Register

A catalog of applicable legal, regulatory, and contractual requirements with owners, applicability rationale, evidence sources, and review cycles.

Related: Regulatory Mapping, Third-Party Risk
Data Subject Rights

Legal entitlements of individuals over their personal data, such as access, correction, deletion, portability, and objection, each with response deadlines.

Data Protection Impact Assessment

A structured review of a processing activity's necessity and risks to individuals, performed before launch and used to design privacy safeguards.

Related: Data Subject Rights, Privacy by Design
Privacy by Design

Building privacy safeguards into systems and processes from the outset rather than retrofitting them, including data minimization and default protective settings.

Related: Data Protection Impact Assessment, Data Classification
Breach Notification Duty

The legal or contractual obligation to inform regulators and affected individuals within defined timeframes after discovering a qualifying data incident.

Related: Incident Severity Classification, Data Subject Rights
Security Architecture

The structural design of security controls, trust boundaries, and reference patterns that guides how systems are built and integrated across the enterprise.

Related: Reference Architecture, Defense in Depth
Defense in Depth

Layering independent controls across people, process, and technology so a single failure does not lead to compromise of critical assets.

Related: Security Architecture, Zero Trust
Zero Trust

An access model that verifies every request based on identity, device posture, and context rather than assuming trust from network location.

Related: Defense in Depth, Privileged Access Management
Reference Architecture

An approved, reusable blueprint of components and patterns that project teams adopt, reducing design variance and speeding secure delivery.

Related: Security Architecture, Technical Debt
Technical Debt

Deferred design or remediation work whose accumulated interest shows up as higher operating cost, slower change, and greater exposure over time.

Related: Reference Architecture, Security Roadmap
Incident Severity Classification

A predefined scale that maps observed incident characteristics to response levels, escalation paths, and notification obligations.

Related: Incident Response Plan, Breach Notification Duty
Incident Response Plan

Documented roles, phases, communication paths, and decision criteria that guide the organization from detection through recovery and lessons learned.

Related: Incident Severity Classification, Tabletop Exercise
Tabletop Exercise

A facilitated discussion-based simulation that tests whether decision-makers, plans, and communications work under a realistic scenario without live systems.

Related: Incident Response Plan, Business Impact Analysis
Business Impact Analysis

An analysis identifying critical processes, their dependencies, and the harm caused by downtime, producing recovery time and recovery point objectives.

Related: Recovery Time Objective, Tabletop Exercise
Recovery Time Objective

The maximum acceptable elapsed time to restore a process or system after disruption, which drives continuity architecture and investment decisions.

Related: Business Impact Analysis, Recovery Point Objective
Recovery Point Objective

The maximum acceptable amount of data loss measured in time, determining backup frequency and replication design for each system.

Related: Recovery Time Objective, Business Impact Analysis
Crisis Management

The executive-level coordination of decisions, stakeholders, and external messaging when an event threatens the organization's viability or reputation.

Related: Incident Response Plan, Tabletop Exercise
Least Privilege

Granting identities only the access needed for their current tasks, for only as long as needed, and removing it when the need ends.

Related: Privileged Access Management, Role-Based Access Control
Privileged Access Management

Controls that vault, broker, record, and periodically review high-risk administrative accounts and sessions to limit abuse and support accountability.

Related: Least Privilege, Zero Trust
Role-Based Access Control

An authorization approach that assigns permissions to job-derived roles and then assigns people to roles, simplifying reviews and provisioning.

Related: Least Privilege, Access Recertification
Access Recertification

A periodic, documented review in which managers or system owners confirm or revoke each user's entitlements to prevent privilege accumulation.

Related: Role-Based Access Control, Least Privilege
Data Classification

A scheme that labels information by sensitivity and value so handling, retention, and protection requirements can be applied consistently.

Third-Party Risk

The exposure created when vendors, suppliers, or service providers hold data, connect to networks, or deliver functions the organization depends on.
