What is residual risk and why is it important? – Residual risk is the risk that remains after efforts to identify and eliminate some or all types of risk have been made. Residual risk is important for several reasons. First to consider is that residual risk is the risk “left over” after security controls and process improvements have been applied.
- This means that residual risk is something organizations might need to live with based on choices they’ve made regarding risk mitigation,
- Or they could opt to transfer the residual risk, for example, by purchasing insurance to offload the risk to an insurance company.
- Another reason residual risk consideration is important is for compliance and regulatory requirements – for example, International Organization for Standardization 27001 stipulates this risk calculation.
Finally, residual risk is important to calculate for determining the appropriate types of security controls and processes that get priority over time.

What is an example of residual risk?
The residual risk is the amount of risk or danger associated with an action or event remaining after natural or inherent risks have been reduced by risk controls. The general formula to calculate residual risk is where the general concept of risk is ( threats × vulnerability ) or, alternatively, (severity × probability). An example of residual risk is given by the use of automotive seat-belts, Installation and use of seat-belts reduces the overall severity and probability of injury in an automotive accident ; however, probability of injury remains when in use, that is, a remainder of residual risk.
What are residual safety risks?
Residual risk is the risk that remains after your organization has implemented all the security controls, policies, and procedures you believe are appropriate to take. Or, phrased another way: residual risk is risk that can affect your business even after taking all appropriate security measures.
What is the ISO definition of residual risk?
Term ‘residual risk’ is mandatory in the risk management process according to ISO 27001, but is unfortunately very often used without appreciating the real meaning of the concept. What is residual risk? Residual risk is the risk remaining after risk treatment.
After you identify the risks and mitigate the risks you find unacceptable (i.e. treat them), you won’t completely eliminate all the risks because it is simply not possible – therefore, some risks will remain at a certain level, and this is what residual risks are. The point is, the organization needs to know exactly whether the planned treatment is enough or not.
Residual risks are usually assessed in the same way as you perform the initial risk assessment – you use the same methodology, the same assessment scales, etc. What is different is that you need to take into account the influence of controls (and other mitigation methods), so the likelihood of an incident is usually decreased and sometimes even the impact is smaller.
What is an example of a residual risk in the workplace?
An example of residual risk in a workplace is stairs leading up to an office ; it is not practical to set rules around the use of the stairs, but an accident leading to an injury or possibly even death could still occur.
How do you identify residual risk?
How to Calculate Residual Risk – Before a risk management plan can be designed, you need to quantify all of the residual risks unique to your digital landscape. This will help define the specific requirement for your management plan and also allow you to measure the success of your mitigation efforts.
Quantifying residual risks within an ecosystem is a highly complex calculation. At a high level, the formula is as follows: Residual risk = Inherent risks – impact of risk controls. Residual risks can also be assessed relative to risk tolerance (or risk appetite) to evaluate the effectiveness of recovery plans.
This will enforce an audit of all implemented security controls and identify any lapses permitting excessive inherent risks. With such invaluable analytics, security teams can conduct targeted remediation campaigns, supporting the efficient distribution of internal resources.
How do you identify the residual risk?
Subtracting the impact of risk controls from the inherent risk in the business (i.e., the risk without any risk controls) is used to calculate residual risk.
What is the difference between risk and residual risk?
Inherent Risk is typically defined as the level of risk in place in order to achieve an entity’s objectives and before actions are taken to alter the risk’s impact or likelihood. Residual Risk is the remaining level of risk following the development and implementation of the entity’s response.
Is residual risk the same as active risk?
Active Risk vs. Residual Risk – Residual risk is company-specific risks, such as strikes, outcomes of legal proceedings, or natural disasters. This risk is known as diversifiable risk, since it can be eliminated by sufficiently diversifying a portfolio.
There isn’t a formula for calculating residual risk ; instead, it must be extrapolated by subtracting the systematic risk from the total risk. Active risk arises through portfolio management decisions that deviate a portfolio or investment away from its passive benchmark. Active risk comes directly from human or software decisions.
Active risk is created by taking an active investment strategy instead of a completely passive one. Residual risk is inherent to every single company and is not associated with broader market movements. Active risk and residual risk are fundamentally two different types of risks that can be managed or eliminated, though in different ways.
What is the difference between acceptable risk and residual risk?
After calculating and prioritizing recognized risks, the process moves on to identify and implement controls to eliminate, reduce and/or mitigate risks. How are risks controlled? Are the residual risks acceptable – Is there a criterion? Who approves residual risks in the organization? In the first two parts of this series, risk identification ( Series 1 of 3 ), risk calculation and analysis ( Series 2 of 3 ) were discussed.
- In this last installment, risk control approaches are presented.
- As earlier defined, a risk is the probability of a hazard resulting to damage, injury, liability, loss, or any other negative occurrence that is caused by external or internal vulnerabilities.
- Methods of identifying risks are brainstorming, process mapping or flowcharting, risk surveys, and SWOT (strength, weakness, opportunity, threat) analysis.
Risks depend on frequency of exposure, access, likelihood of injury, and severity of injury. Quantification of risks can be undertaken by using matrix tables and mathematical calculations. For all quantified risks, sort the RPNs (risk priority numbers) from highest to lowest.
A threshold RPN is established by the assessment team, and anything below that threshold will be considered low risk and will be eliminated from the list. Moreover, the assessment team can designate RPNs as low, medium, high, and extreme risks. As a rule, the highest RPNs are given the utmost importance for corrective action.
Extreme Risk requires immediate action, High Risk needs significant attention, and Medium Risk can be subject to further scrutiny. Low Risk can be eliminated and not subject to additional review. The PDCA Cycle and Risk Assessment In risk assessment, the risk calculation process is repeated again and again following the continual improvement cycle called PDCA (plan-do-check-act), also known as the Deming Cycle.
PDCA is implemented in order to improve a process or product. This cycle is repeated over-and-over until the law of diminishing returns sets in. In risk management, a series of controls is introduced to lower risks until such time that an appropriate control is able to bring down residual risks to an acceptable level.
The PDCA process finds substantial application when reviewing residual risks with the adoption of defined acceptance criteria. In a nutshell, PDCA is briefly described as: · Plan: Analyze existing condition, and plan opportunities for improvement · Do: Implement the plan by pursuing laid out procedures · Check: Evaluate, review and analyze results of plan implementation · Act: Implement process/product change. SOURCE: www.WP1.com Based on the risk analysis, a corrective action plan can be generated to lower identified risks. Corrective actions can include engineering controls, additional training, inspections, closer coordination and interaction with employees and supervisors, PPE, etc.
- Inputs from end users (employees, supervisors and managers) on process improvement should always be sought and are always welcome.
- Designate the responsible personnel and target date of completion.
- Control of Hazards and Risks OSHA’s Hierarchy of Controls, also known as levels of protection, provides an evaluation of the different echelons of safety intervention.
The hierarchy is used to identify sound methods for eliminating, reducing and/or controlling hazards and risks. The hierarchy is as follows: 1. Elimination: Removal of the hazard – the most effective control 2. Substitution: Replace with non-hazardous material or process 3. SOURCE: www.cdc.gov In order to achieve overall success and sustainability of controls, there is a need for management involvement and employee participation. Involvement through a consultative process allows inputs from end users, ensures understanding of objectives, and fosters accountability and empowerment at every level.
Engagement breeds awareness, buy-in, and ownership. One thing that provides an ineffectual solution is for a control to be designed and evaluated by a corporate officer or consultant without input from end users. In most cases, the absence of consultation results to resistance and failure of the control.
Always document changes to the process or product. Review and revise existing policies and procedures to reflect changes based on results of risk assessment and risk control. Residual Risks After planning a corrective action, the risks are recalculated.
The objective of the introduction of a control is to eliminate or lower identified risks. If the calculated risks are acceptable due to the adopted corrective actions, then the residual risk is called as acceptable risk, i.e., it will not result to any irreversible, serious injury or death. If the risk is still above the threshold, a reassessment of the problem is warranted and an introduction of new ideas to lower the risks is necessary.
In the same example used in earlier articles, an individual works through unguarded rotating motor gears with very easy access that can result to crushed or severed fingers or hand. In an earlier risk calculation ( Series 2 of 3 ), the RPN was determined at 48.
- For purposes of presenting progression of controls that demonstrate reduction of residual risks, calculations are performed under these scenarios: no control; an initial administrative control; and then engineering control.
- For these calculations and interpretations, see Tables 1-5 ( Series 2 of 3 ) for Frequency, Ease of Access, Likelihood of Injury, Risk Matrix, and Calculated Risks.
Risk Priority Number (RPN) without Control = Frequency * Detection * Severity = (4)(4)(3) = 48 ~ considered to be Extreme Risk. The RPN of the existing situation without any form of control is considered an Extreme Risk, and therefore not acceptable. As an administrative control, the individual can be required to work away from the rotating motor gears.
- This administrative control results to: lowered frequency at 3 (once or more per shift), and lessened access to dangerous parts at 3 (easily accessible and close to dangerous part).
- However, the severity stays the same at 3 (irreversible or serious injury).
- Residual Risks with Administrative Control = Frequency * Detection * Severity = (3)(3)(3) = 27 ~ considered to be High Risk.
The residual risk after the adoption of distance control is considered High Risk, and it is still not acceptable. If an engineering control is introduced, say machine guarding on the rotating motor gears, this will prevent access to the dangerous parts.
- This engineering control results to: lowered frequency at 1 (very low), and very difficult to access dangerous parts at 1 (requiring considerable effort to access dangerous parts like using a tool to remove guarding).
- The severity is the same at 3 (irreversible or serious injury).
- Residual Risks with Engineering Control = Frequency * Detection * Severity = (1)(1)(3) = 3 ~ considered to be Low Risk.
The residual risk after the installation of machine guarding is considered Low Risk, and therefore acceptable. Management of High Residual Risks Various options for controls should always be explored, especially for proposed measures that have substantial resource requirements.
- By analyzing residual risks and investment requirements, a planned approach to risk management can be employed.
- If all feasible and practical actions have been undertaken to reduce risks but still the risks are high, a system of residual risk approval should be developed and applied.
- High residual risks should be approved by organizational authority, i.e., by a high-ranking company officer like a President, Chief Operating Officer, Vice President, or Director.
The following criteria can be utilized when dealing with high residual risks. Critical items to the organization should be identified, and ensure to distinguish critical items from those that are “nice to have.” Create a list of items and narrow them down to the most important ones in order to concentrate precious resources (personnel, time and finances) in achieving such organizational goals.
Start laying down the criteria for segregating high-priority items from low priority items. Follow these steps: 1. Identify items that are most valued by the organization by going back to the corporate objectives, goals and strategies.2. Determine items with the greatest impact on productivity, performance or profitability – Examine organizational performance metrics that are linked to priority items.3.
Single out items that are most challenging.4. Recognize the priority item the team is best situated to accomplish – by virtue of talent, skill, or training. The implementation of a risk-based methodology is a proactive approach that allows identification, analysis, and control of risks.
Is residual risk zero?
Do you need to be at zero risk? – You might not get to zero, but you can reduce the risk. Maintaining equipment reduces the risk of a problem or fault. Staying healthy reduces the risk of a heart attack and other medical problems. Checking the weather forecast reduces the likelihood you will be caught out by any unexpected wind, rain, and storms.
- At work, the goal of your risk assessment isn’t to reduce risk to zero.
- But it is to reduce risk.
- As close to zero as you can get.
- To do this, think about what could go wrong, and minimise the chance of that happening.
- This is basically what the risk assessment process is.
- Once you know what could go wrong, control measures can be put in place to make the risk smaller.
For example, the risk of someone falling from height is much greater from a ladder than it is from a scaffold platform with proper edge protection. They no longer need to hold on and have both arms free to carry out the work. Less chance of falling, or dropping something from height.
It could still happen, but the risk is much lower. You are not expected to eliminate all risks, because, quite simply it would be impossible. When sawing wood, you could reduce the risk of wood dust inhalation by wearing a dust mask and carrying out the work outside, where ventilation is better, so that dust doesn’t build up in the workplace.
But that exposes you to the weather, and sun exposure increases the risk of skin damage, In some cases, removing one risk can introduce others, your challenge is to choose the best solution that creates the lowest risk. Of course, the best way to control risk is to eliminate it. Where you can, you should. But you are not expected to eliminate all risks.
The law doesn’t require this, it wouldn’t be practical. Can you use a saw or a drill without any risk at all? No. Can you control the risks and prevent harm by putting safety measures in place? Yes! What the law requires is for risk to be reduced as low as is reasonably practicable, This is known as ALARP,
This means controlling hazards and minimising risks as much as you can. If there is a safer way of doing the job, you should take it. If there are control measures that will help keep your workplace safe, you should use them. If the risk is above zero, it may be acceptable.
- If the risk is above ALARP, it’s too much.
- The risk can’t be zero, but it can be reduced.
- There will always be some level of risk remaining.
- This is known as residual risk,

Can residual risk be high?
Is There Any Value In Measuring Residual Risk? Acknowledging that there was a lot of misunderstanding about residual risk, Mr. Ramesh Pillai (Chairman of Board of Governors, Institute of Enterprise Risk Practitioners) first clarified the differences between Residual and Inherent risk.
Residual risk, he explained, is used in Risk and Control Self-Assessment (RCSA), and is also alluded to in Risk Registers. Primarily related to operational risk, residual risk is usually measured when a firm wants to do business in a known hotspot, for instance, and needs to assess how much risk its project may be exposed to, and whether the firm’s risk appetite could support it.
To assess or not to assess “When you evaluate anything, you need to evaluate the control environment as well,” explained Mr Ramesh. Therefore, it is worthwhile assessing residual risk if the firm is assessing controls because controls are mitigative measures.
However, some firms tend to get distracted when conducting risk analysis, and end up attributing too much importance to terms like “inherent risk,” becoming overly concerned about what it represents within their context. Remarking that firms like these cannot get comfortable with the current state of their control environment without having a firm grasp on the assessed inherent risk for that scenario, he attributed it to the way they conducted risk assessments before.
“Their first step was to identify the inherent risk, then factor in controls to arrive at residual risk,” he said, clarifying that while inherent risk represented the amount of risk that existed in the absence of controls, residual risk, on the other hand, was the amount of risk remaining after controls are accounted for.
However, while the definition of the two terms appear fairly straightforward, their practice does give rise to some challenges; in particular, when closer scrutiny of the “no controls environment” pertaining to inherent risk brings to light that controls did exist in the environment, and only some had been excluded.
“The flaw with inherent risk is that in most cases, it does not explicitly consider which controls are being included or excluded,” Mr Ramesh said. “In a truly inherent risk state, for example, there would be no employee background checks or interviews, and no locks on doors for security.
This could lead to all risk scenarios being evaluated as inherently high.” Understanding what you need It could also lead to the arbitrary treatment of inherent risk, so a more realistic and useful definition of inherent risk would be the current risk level, given the existing set of controls, rather than an absence of controls.
That would make residual risk the risk level remaining, after additional controls are applied. Clarifying the two terms in this way helps to dispel the ambiguity of the “no controls” notion of inherent risk. Controls tend to be factored in for any scenario, regardless of the kind of risk which is connected to it.
It is usual industrial practice when measuring current risk levels for a given scenario, to factor controls into either the frequency or magnitude aspects. These are normally based on things like avoidance, deterrence or methods of response and other mitigative measures. “Doing this allows you to be more intentional when choosing controls,” Mr Ramesh said.
“You can choose to include or exclude certain controls from your analysis, depending on what works and what doesn’t.” It’s in the controls Residual risk and inherent risk are two different things but have similarities in some areas. Inherent and residual risk are connected in that inherent risk, less the effect of controls, equals residual risk.
This implies that residual risk will always be less than or equal to inherent risk. However, there are instances where residual risk can be higher. This depends on the controls used to modify the risks. “Control” is defined as a specific action taken to reduce either the likelihood of the risk occurring, and/or the consequences of the risk occurring.
This implies that residual risk must be less than inherent risk. However, ISO 31000 has a slightly different perspective of control, defining it as a “measure that is modifying risk” without the implication that it is always reduces the risk. In the business environment, some companies may actually choose to have higher residual risk because higher risk means higher returns.
Higher operational risk may not be good, but Enterprise Risk Management (ERM) allows the firm to raise its risk to levels according it is comfortable with. “It is worth thinking about raising residual risk if you are assessing controls,” advised Mr Ramesh. “But it takes time and a lot of data – at least three years’ worth of clean data.” Conclusion The main challenge for companies choosing to measure residual risk is how to measure it accurately for maximum benefit.
But even the best efforts may be only arbitrary, Mr Ramesh cautioned. “Even financial institutions do it arbitrarily,” he said, adding that while analysis could be numerical, strategy rarely was; even “near miss” scenarios – the incidents caught and mitigated at the last minute – could give an inkling of what a company’s inherent risks could be.
At the end of the day, it comes down to risk assessment. He cautioned that with the MACC’s directive to follow ISO 37001, firms should start immediately on their respective gap analyses, in order to meet the deadline of June 2020. While mitigative measures do need to be put in place to keep residual risk low, companies have to run cost-benefit analyses to determine if the returns will be worthwhile.
They may find that there is no need to measure residual risk as this takes time, effort and resources. Mr Ramesh opined that there was not very much value in measuring residual risk although an assessment should be made. “There is no need to measure residual risk unless you are asked to do it,” he concluded.
What is an example of inherent vs residual risk?
That is inherent risk – no matter how safe and careful you are, it will always exist. But you can take precautions to help protect yourself, such as wearing your seatbelt. If you wear your seatbelt, there is still residual risk, but you have decreased the inherent risk of personal injury.
What is residual risk and how should it be treated?
Identification of Residual Risks – Residual risk is a risk that remains after Risk Management options have been identified and action plans have been implemented. It also includes all initially unidentified risks as well as all risks previously identified and evaluated but not designated for treatment at that time.
What is an example of residual risk in audit?
As we mentioned above, residual risk refers to the risks that exist even after implementing cyber security controls you intend to use for your business. An example of residual risk is if your company implements a policy requiring employees to use complex and character-specific passwords.
Can residual risk be eliminated?
Understanding specific types of risk – Identified risk: That risk that has been determined using analytical tools including the time and costs of analysis efforts, the quality of the risk management process, and the state of the technology involved in affecting the amount of risk that can be identified.
Unidentified risk: That risk that has not yet been identified as some risks are not identifiable or measurable. Blunders in the investigations may expose some unidentified risks. Total risk: The sum of identified and unidentified risk comprises the total risk. Acceptable risk : The part of identified risk that is allowed to remain after controls are implemented and determined acceptable to an individual, organization or community.
Unacceptable risk : The part of identified risk that cannot be tolerated, but must be either eliminated or controlled. Residual risk : The part of total risk that remains after management efforts have been employed (the remaining risk after the control measures are in place). Residual risk – the inherent risk in all organizational activities. The presence of residual risk means that they cannot be eliminated. Consequently, strategies need to be employed to manage inherent danger, and workers need to be more vigilant because of it.
- Just as we can’t eliminate the risk of tripping on stairs or else we can’t remove all the stairs in the world.
- By replacing those with ramps could also lead to trips because the floor level rises.
- Even if we try to get rid of all stairs and ramps, and only had level flooring but still people could trip over their shoelaces and finally if we would remove shoelaces, but then also they could trip when their loose shoe falls down.
So, if it’s noticed in some cases, removing one risk can instigate others. Understanding residual risks Residual risk can be studied with another example of ladder. Ladders are not actually a working platform, and not designed for work at height. They don’t have full edge protection, and it is not much safe to climb a ladder and carry out tasks safely. The general formula to calculate it is:

What is an example of inherent and residual risk?
Residual risk is the remaining risk associated with a course of action after precautions are taken. Another personal example will make this clear. When you drive your car, you’re taking the risk that you might cause an accident. That is inherent risk – no matter how safe and careful you are, it will always exist.
What is an example of a residual risk in cybersecurity?
What Does Residual Risk Mean in the Risk Management Process? – Residual risk in the risk management process is the residual risk remaining after an organization’s attempt to mitigate or remediate that risk. For example, even after implementing an email security service to detect spam and phishing attacks, your organization continues to receive phishing emails.
What is the difference between risk and residual risk?
Inherent Risk is typically defined as the level of risk in place in order to achieve an entity’s objectives and before actions are taken to alter the risk’s impact or likelihood. Residual Risk is the remaining level of risk following the development and implementation of the entity’s response.
