It establishes a system of checks and balances to ensure risk is managed effective.
**1. First Line of Defense (Operational Management):** These are the **risk owners**. Business unit managers and process owners are directly responsible for owning and managing risks day-to-day. They implement and maintain internal controls, execute operational procedures, and apply corrective actions to mitigate risks inherent in their specific business activities.
**2. Second Line of Defense (Risk Management and Compliance):** These functions provide **oversight, monitoring, and challenge**. They do not own the operational risks but establish the governance frameworks, policies, and tools used by the first line. Teams such as Information Security, Enterprise Risk Management (ERM), and Legal Compliance typically reside here. They monitor the first line to ensure controls are designed correctly and policies are followed.
**3. Third Line of Defense (Internal Audit):** This function provides **independent assurance**. Internal Audit operates independently of management, reporting directly to the Board or Audit Committee. They objectively evaluate the effectiveness of the first two lines, providing assurance that governance, risk management, and control processes are operating as intended.
For a CRISC candidate, understanding this model is critical for defining clear accountability and ensuring that the organization's risk appetite is supported by a structured hierarchy of control and review.
Mastering the Lines of Defense in Risk Governance for CRISC
What is the Lines of Defense Model?
The Three Lines of Defense model is a fundamental framework in risk governance that clearly defines roles and responsibilities for risk management and internal control within an organization. For a CRISC candidate, understanding this hierarchy is crucial because ISACA emphasizes that everyone in an organization plays a role in risk management, but those roles must be distinct to maintain checks and balances.
The model distinguishes among three groups: those who own and manage risks, those who oversee risks, and those who provide independent assurance.
Why is it Important?
Without defined lines of defense, risk management fails due to accountability gaps. This model ensures: 1. No gaps in coverage: Every risk is owned by someone. 2. No duplication of effort: Risk management and Audit do not perform the exact same tasks. 3. Objectivity: Auditors remain independent from the management functions they review.
How it Works: The Three Lines
The First Line: Operational Management (Risk Owners) These are the 'doers.' They are responsible for the day-to-day operation of the business. They own the risks associated with their operations and are responsible for implementing corrective actions to address process and control deficiencies. Key Responsibilities: Identifying risks, implementing controls, and executing daily procedures.
The Second Line: Risk Management & Compliance (Risk Overseers) These functions facilitate and monitor the implementation of effective risk management practices by operational management. They help define the risk framework and ensure the first line is following it. Key Responsibilities: Setting policies, monitoring compliance, aggregating risk reports (e.g., the Risk Management Office or Compliance Department).
The Third Line: Internal Audit (Independent Assurance) This line provides the governing body and senior management with comprehensive assurance based on the highest level of independence and objectivity within the organization. They are not responsible for managing the risk; they are responsible for verifying that the first and second lines are doing their jobs effectively. Key Responsibilities: Auditing controls, verifying framework effectiveness, and reporting directly to the Audit Committee/Board.
Exam Tips: Answering Questions on Lines of Defense
When facing CRISC exam questions regarding risk roles, follow this logic:
1. Identify the 'Owner': If the question asks who is responsible for accepting risk or remediating a control failure, the answer is almost always Operational Management (First Line). Do not select the Risk Manager for risk acceptance; they only advise.
2. Identify the 'Framework': If the question refers to creating the methodology, facilitating risk assessments, or maintaining the risk register, look for the Risk Management Function (Second Line).
3. Look for 'Independence': If the question asks for an objective review or who validates the effectiveness of the risk team, the answer is Internal Audit (Third Line).
4. Watch for Conflict of Interest: A common exam scenario involves a Risk Manager (2nd Line) implementing controls (1st Line work) or an Auditor (3rd Line) designing the risk framework (2nd Line work). In the context of CRISC, these are violations of the segregation of duties.
