Organizations implement different strategies to manage and mitigate risks. Despite putting their best foot forward, there are some risks that still stay around. These risks are called residual risks. 

Calculating residual risk is essential because it helps organizations understand the level of risk that remains after implementing all possible risk mitigation measures. Calculating residual risks allows organizations to make informed decisions about whether the remaining risk is acceptable or if additional controls are necessary. It also supports compliance with regulatory requirements (such as ISO 27001) and ensures that resources are allocated efficiently to address the most critical vulnerabilities. 

By identifying and evaluating residual risk, organizations can enhance their overall risk management strategy, maintain a robust security posture, and better protect their assets and data from potential threats.

This article is dedicated to residual risks and how to deal with them.

Section 1: Understanding residual risk

What is residual risk?

Residual risk definition: Residual risk is the level of risk that remains after all risk management efforts, such as identification, assessment, and mitigation, have been applied. It represents the remaining vulnerabilities and threats that persist even after implementing controls and safeguards to reduce inherent risks. 

Understanding residual risk is crucial for organizations to determine if the remaining risk is within acceptable levels or if further actions are required. It is an essential component of comprehensive risk management strategies, ensuring that organizations can prioritize and address the most critical risks effectively.

What is the difference between residual risk and inherent risk?

The following table shows the comparison: inherent risk vs. residual risk.

Practical examples of residual risks

Practical examples of residual risks can be found in various everyday activities and professional settings:

1. Driving a car: Even with seat belts, airbags, and defensive driving techniques, there remains a residual risk of accidents due to factors like other drivers’ behaviors or road conditions.
2. Cybersecurity: What is residual risk in cyber security? After implementing firewalls, encryption, and other cybersecurity measures, there remains a residual risk of data breaches due to sophisticated hacking techniques or human errors.
3. Manual handling: Even with proper lifting techniques and ergonomic training, workers face a residual risk of injury from unexpected movements or excessive loads.

Section 2: Types of residual risk

1. Operational risk

Operational risk refers to the risks that arise from the day-to-day activities and processes within an organization. These risks can be due to internal failures such as human errors, system breakdowns, or procedural inefficiencies. For example, despite implementing robust operational procedures and training programs, there remains a residual risk that employees may still make mistakes or that critical machinery may fail unexpectedly. 

Operational risks can also include external events like natural disasters or supply chain disruptions that can impact the continuity of operations. Managing these risks involves continuous monitoring and improvement of internal processes to mitigate potential disruptions.

2. Financial risk

Financial risk encompasses the uncertainties related to the financial health and performance of an organization. This includes risks such as market fluctuations, credit risks, and liquidity issues. Despite implementing comprehensive financial controls and risk management strategies, there is always a residual risk due to the unpredictable nature of financial markets and economic conditions. 

For instance, an organization might face unexpected financial losses due to sudden changes in interest rates, currency exchange rates, or default by a major client. Proper financial planning, diversification of investments, and maintaining adequate reserves are some of the strategies used to manage financial risks.

3. Compliance risk

Compliance risk pertains to the potential for breaches of laws, regulations, or internal policies. This type of risk is particularly significant in industries that are heavily regulated, such as finance, healthcare, and manufacturing. Despite implementing rigorous compliance programs and conducting regular audits, there is always a residual risk of non-compliance due to factors such as regulatory changes, human oversight, or differing interpretations of legal requirements. 

Non-compliance can result in legal penalties, fines, and damage to an organization’s reputation. Effective compliance risk management involves staying updated with regulatory changes, training employees, and establishing a culture of compliance within the organization.

4. Strategic risk

Strategic risk involves the long-term threats that can impact an organization’s ability to achieve its goals and objectives. These risks can arise from shifts in market dynamics, technological advancements, competitive pressures, or changes in consumer preferences. Even with strategic planning and risk assessments, there remains a residual risk that unforeseen events or misaligned strategies could negatively affect the organization’s future success. 

For example, a new competitor entering the market with a disruptive technology could render a company’s product obsolete. To manage strategic risks, organizations must engage in continuous market analysis, adapt to changes, and maintain flexibility in their strategic plans.

Section 3: Identifying residual risk

Step 1: Conduct a risk assessment

• Identify inherent risks: Begin by identifying all potential risks before any controls are applied. This involves understanding the natural level of risk in your processes, systems, and operations.
• Analyze risk scenarios: Consider various risk scenarios to determine the likelihood and impact of different threats materializing.

Step 2: Implement risk controls

• Apply mitigation measures: Implement risk controls and mitigation strategies to reduce the identified inherent risks. These can include security measures, process improvements, and compliance with standards and regulations.
• Document controls: Keep detailed records of all controls implemented and their expected impact on reducing risk.

Step 3: Evaluate the effectiveness of controls

• Perform control testing: Conduct tests and audits to assess the effectiveness of the implemented controls. This helps in understanding how well the controls are mitigating the risks.
• Review control performance: Analyze the performance data to identify any gaps or weaknesses in the controls.

Step 4: Calculate residual risk

• Use the residual risk formula: Apply the traditional residual risk formula: 
  • Residual risk = Inherent risk – Impact of risk controls. 
  • This calculation helps quantify the remaining risk after controls have been applied.
• Assess likelihood and impact: Evaluate the likelihood and potential impact of the residual risks to prioritize them effectively.

Step 5: Compare with risk tolerance

• Define risk tolerance levels: Establish your organization’s risk tolerance thresholds to understand what levels of residual risk are acceptable.
• Evaluate acceptability: Compare the calculated residual risks against your risk tolerance levels to determine if they are within acceptable limits. If not, consider additional mitigation strategies or risk acceptance.

Step 6: Document and communicate findings

• Create a risk register: Maintain a comprehensive risk register that includes all identified risks, their inherent and residual levels, and the controls applied.
• Report to stakeholders: Communicate the findings to relevant stakeholders, including management and risk committees, to ensure transparency and informed decision-making.

Section 4: Managing residual risk

Mitigating residual risks involves several strategies to reduce the remaining risk after initial controls have been applied. By employing these strategies, organizations can effectively manage and mitigate residual risks, ensuring they remain within acceptable levels and supporting the overall risk management framework.

Here are key strategies to manage and mitigate residual risks effectively:

1. Risk avoidance

• Eliminating risky activities: Avoid activities or processes that introduce significant residual risks if they are not essential to operations. This can mean discontinuing certain projects or using safer alternatives.

2. Risk reduction

• Enhancing controls: Strengthen existing controls or implement additional controls to further mitigate the risk. This can include advanced security measures, increased monitoring, and improved safety protocols.
• Training and education: Regularly train and educate employees on best practices and new procedures to minimize human error and enhance awareness of potential risks.

3. Risk transfer

• Insurance policies: Transfer the risk to third parties by purchasing insurance. This can cover financial losses due to residual risks that cannot be entirely eliminated.
• Outsourcing: Outsource certain operations to third-party vendors who specialize in managing those specific risks.

4. Risk acceptance

• Risk tolerance levels: Establish and define the organization’s risk tolerance levels. Accept residual risks that fall within these acceptable limits and ensure they are documented and monitored.
• Cost-benefit analysis: Perform a cost-benefit analysis to determine if the cost of further mitigating the risk outweighs the potential impact of the residual risk.

5. Regular monitoring and review

• Continuous monitoring: Implement continuous monitoring systems to track the effectiveness of controls and identify any changes in the risk environment. This helps promptly address any emerging risks.
• Periodic audits: Conduct regular audits and reviews to ensure that controls remain effective and that residual risks are managed appropriately.

6. Leverage frameworks and best practices

• Adopt established frameworks: Use established risk management frameworks and best practices to structure and guide the risk mitigation process. Frameworks like ISO 31000 or COSO can provide a comprehensive approach to managing residual risks.

7. Assign responsibilities

• Designate risk owners: Assign specific individuals or teams responsible for managing residual risks. This ensures accountability and focused efforts on risk mitigation activities.
• Resource allocation: Allocate appropriate resources, including budget and personnel, to address and manage residual risks effectively.

Section 5: The importance of ongoing monitoring and periodic reviews for residual risk

Ongoing monitoring and periodic reviews are essential components of effective residual risk management. These practices ensure that the controls in place continue to mitigate risks effectively and that any new risks are promptly identified and addressed.

1. Continuous improvement

Regular monitoring allows organizations to continuously improve their risk management processes. By keeping track of residual risks and evaluating the effectiveness of controls, organizations can make necessary adjustments to enhance their risk mitigation strategies.

2. Adaptation to changes 

The business environment is dynamic, and risks can evolve due to changes in technology, regulations, market conditions, or internal processes. Ongoing monitoring helps organizations stay alert to these changes and adapt their risk management practices accordingly.

3. Ensuring compliance 

Periodic reviews help ensure that the organization remains compliant with regulatory requirements. Regular assessments and updates to compliance programs are necessary to address any gaps or deficiencies that could lead to non-compliance and associated penalties.

4. Early detection of new risks

Ongoing monitoring provides early detection of emerging risks that were not previously identified or that have developed due to changes in the environment. This allows organizations to take proactive measures to mitigate these new risks before they escalate.

5. Resource allocation 

By regularly assessing residual risks, organizations can better allocate resources to areas with the highest risk exposure. This ensures that efforts and investments are focused on mitigating the most critical risks, thereby optimizing the risk management process.

6. Maintaining acceptable risk levels

The goal of monitoring residual risk is to ensure that it remains within acceptable levels defined by the organization’s risk tolerance. This ongoing vigilance helps maintain operational stability and protect the organization from unforeseen adverse events.

Section 6: Risk prioritization

Risk prioritization involves identifying the most critical risks to address them effectively. Here are some common methods for prioritizing risks:

• Risk scoring: This method involves assigning scores to risks based on factors such as impact and probability. These scores help determine the priority of each risk. High-scoring risks are addressed first.
• Control matrix: A control matrix maps risks against controls and their effectiveness. By evaluating which controls mitigate which risks, organizations can prioritize the most critical risks that lack sufficient controls.
• Cardinal risk ranking: This quantitative technique uses numerical values to rank risks. It considers factors like the probability of occurrence and the potential impact. Higher-ranked risks are prioritized.
• Probability and impact matrix: Risks are plotted on a matrix based on their likelihood and impact. Those in the high-probability, high-impact quadrant are prioritized first.
• Risk minimization techniques: This involves strategies like risk transfer, risk acceptance, and risk mitigation. By addressing risks through these strategies, organizations can focus on minimizing the most significant risks first.
• Qualitative methods: These include expert judgment and scenario analysis to prioritize risks. Experts evaluate risks based on experience and qualitative factors to determine which should be prioritized.
• Quantitative techniques: These methods use numerical data to prioritize risks. Examples include probability analysis, cost-benefit analysis, and time frame assessment.
• Simple ranking: This involves ranking risks from highest to lowest based on their perceived importance. It is a straightforward approach that can be useful in less complex situations.
• Three-step process: Identifying and assessing risks, determining the probability of each risk occurring, and prioritizing actions based on these assessments.

Section 7: Frameworks and standards you can follow for risk management

Organizations have several established frameworks and standards to choose from for effective risk management. Here are some of the most widely recognized ones:

1. ISO 31000: Provides guidelines for risk management applicable to any organization, regardless of size or industry. It outlines principles, a framework, and a process for managing risk.
2. ISO 27001: This standard addresses residual risk by ensuring that all potential risks are identified, assessed, and managed. It emphasizes continuous monitoring and improvement of risk management processes.
