Determining risk levels for your business is a crucial step in ensuring its stability and growth.
The first step in determining risk levels is to identify the potential risks that could impact your business, such as market fluctuations, regulatory changes, or supply chain disruptions.
You can use the risk assessment matrix to categorize and prioritize these risks based on their likelihood and potential impact. For example, a risk with a high likelihood and high potential impact would be considered a high-risk category.
By understanding the different risk levels, you can develop strategies to mitigate or manage them, such as diversifying your investments or implementing a disaster recovery plan.
Understanding Risk Levels
Understanding risk levels is crucial in managing risk effectively. You can create a risk scale with up to 10 risk levels, allowing for a high level of granularity in your risk assessment.
To determine the risk levels, you can specify the size of the risk level scale, and Identity Governance will automatically divide the levels in even increments. The maximum risk value for calculated values will be set to the maximum value specified in your settings.
You can further customize the risk levels by providing your own naming system and assigning a color-code to each level, ranging from blue at the low end to red at the high end.
Here's a breakdown of the risk level categories:
These categories will help you evaluate the likelihood of a risk occurring and inform your risk management strategy.
Common Internal:
Common internal risks can sneak up on businesses, causing significant problems. Human error is a major contributor, leading to unintentional data leaks and unforeseen costs of doing business.
Inadequate organizational structure and reporting responsibilities can also lead to issues. This can result in ineffective management and a lack of clear accountability.
Asset loss, including damage or destruction of company property, is another common internal risk. This can be due to various reasons, such as union strikes or other unforeseen events.
Here are some common internal risks that businesses should be aware of:
- Human error
- Inadequate organizational structure
- Asset loss
Common External
Common External Risks can be unpredictable and devastating to a business. Natural disasters like hurricanes, flooding, droughts, and earthquakes can strike at any moment.
Economic changes, including recessions and industry disruption, can have a significant impact on a company's bottom line. These changes can be difficult to anticipate.
Political factors, such as changes in governmental policies and regulations, can also pose a risk to businesses. These changes can be sudden and far-reaching.
Cyber attacks, like data theft by hackers and ransomware attacks, are becoming increasingly common. They can have serious consequences for a business's reputation and finances.
Some of the many external risks that businesses face include:
- Natural Disasters
- Economic Change
- Political Factors
- Cyber Attacks
- Many more
Determining Likelihood of Occurrence
Determining the likelihood of occurrence is a crucial step in understanding risk levels. To accurately determine this, you need to consider the probability of the risk event happening. Most companies use a five-category system to determine the likelihood of a risk event.
A risk with a 91 percent or more likelihood of occurring is considered highly likely. Risks in this category are almost certain to occur and require immediate attention. A likely risk, on the other hand, has a 61-90 percent chance of occurring and needs regular attention.
Possible risks may happen about half the time, with a 41-60 percent chance of occurring. These risks need attention, but they may not be as pressing as highly likely or likely risks. Unlikely risks have a relatively low chance of occurring, with an 11-40 percent likelihood. Highly unlikely risks are exactly as they sound, with a low probability of occurring.
Here are the five categories of likelihood in a concise format:
- 1: Highly Unlikely (Low probability of occurring)
- 2: Unlikely (11-40 percent likelihood)
- 3: Possible (41-60 percent likelihood)
- 4: Likely (61-90 percent likelihood)
- 5: Highly Likely (91 percent or more likelihood)
Using a risk assessment matrix can help you visualize the likelihood of a risk event and its potential impact. By plotting the risk on the matrix, you can quickly identify the level of risk and determine the necessary mitigation strategies.
Problems
Risk matrices can be problematic, and it's essential to understand the issues. Tony Cox argues that risk matrices have several mathematical flaws that make it hard to assess risks accurately.
One major issue is poor resolution. Risk matrices can only correctly compare a small fraction of randomly selected pairs of hazards, which is less than 10%. This means that they can't always give us a clear picture of the risks.
Risk matrices can also make errors. They can assign higher qualitative ratings to quantitatively smaller risks, which is not what we want. This can lead to worse-than-random decisions, which is a major problem.
Effective resource allocation is another issue. Risk matrices can't be used to allocate resources to risk-reducing countermeasures because they don't provide enough information.
Ambiguity is also a problem. Categorizations of severity can't be made objectively for uncertain consequences. This means that inputs to risk matrices and resulting outputs require subjective interpretation.
Thomas, Bratvold, and Bickel demonstrate that risk matrices produce arbitrary risk rankings. The rankings depend on the design of the risk matrix itself, such as the scale used.
For example, changing the scale can change the answer. This is a major issue because it means that different people may get different risk ratings for the same quantitative risks.
Another problem is the imprecision used on the categories of likelihood. For instance, the categories 'certain', 'likely', 'possible', 'unlikely', and 'rare' are not hierarchically related. This can make it difficult to compare risks accurately.
A better choice might be to use a hierarchy like 'extremely common', 'very common', 'fairly common', 'less common', 'very uncommon', and 'extremely uncommon'. This can help us compare risks more effectively.
Assigning rank indices to the matrix axes and multiplying the indices to get a "risk score" can also result in an uneven distribution. This means that the risk score may not accurately reflect the actual risk.
Calculating Risk Scores
A risk score quantifies the level of risk that an entity exposes an organization to, with a higher score indicating a greater risk.
To calculate risk scores, you can use Identity Governance to assign risk scores to individual objects, or collect risk score attributes along with objects you collect. You can assign risk scores to users, accounts, applications, permissions, technical roles, separation of duties policies, business roles, and certification policies.
The risk score is based on risk factors and the relative weighting of those factors that you define. The calculation uses variables such as raw risk factor value (RFV), lower boundary (LL), upper boundary (UL), upper risk level value from risk level configuration (URL), and factor weight as a percentage (FW).
Here's a simple formula to calculate the risk score:
FRS = RFV * FW/100
RRFV = (RFV - LL) >0 ? ((RFV - UL) >=0 ? URL: ((RFV * URL / (UL - LL)) : 0
FRS = RRFV * FW/100
RS = SUM FRS[0-N]
To determine a risk score, you must consider two components: risk identification and risk analysis.
What Are Internal Scores?
Internal risk scores are an assessment of any risk factor that comes from within the company. They can be just as damaging as external risks, but often the most difficult to identify because they rely heavily on the company's culture of risk.
Risk factors from within the company can be hard to pinpoint, but they often involve human error or lack of proper procedures. For example, a mid-level manager might be aware of potential internal risks, but struggle to get support from upper management to implement mitigation processes.
To calculate internal risk scores, you need to consider the risk factors and their relative weighting. This involves identifying the potential risks and assigning a risk score based on their likelihood and impact.
Here's a breakdown of the risk factors to consider when calculating internal risk scores:
Understanding internal risk scores is crucial for any organization. By identifying and mitigating these risks, you can reduce the likelihood of security breaches and other negative outcomes.
What Are External Scores?
External risk scores are assessments of anything and everything that could threaten your business from outside the company.
These risks vary greatly and in some cases have few (if any) warning signs.
It's essential to identify potential external risks so your organization has processes in place to react to and mitigate damage as soon as possible.
External risk scores can be unpredictable and may catch you off guard if you're not prepared.
Calculate Score
To calculate a risk score, you need to consider two components: risk identification and risk analysis. Risk identification involves identifying potential risks, while risk analysis involves evaluating the likelihood and impact of each risk.
Risk scores can be calculated using various methods, including multiplying the Risk Impact Rating by Risk Probability. This is the quantifiable number that allows key personnel to quickly and confidently make decisions regarding risks.
A risk score can be calculated using the following formula: Risk = probability of event x magnitude of loss. To determine the probability of occurrence, you can use the following categories: High probability (80% ≤ x ≤ 100%), Medium-high probability (60% ≤ x < 80%), Medium-Low probability (30% ≤ x < 60%), and Low probability (0% < x < 30%).
For risk impact, you can use the following ratings: High to Catastrophic (Rating A – 100), Medium to Critical (Rating B – 50), and Low to Marginal (Rating C – 10).
To determine the likelihood of a risk occurring, you can use the following categories: Highly Likely (91% or more), Likely (61-90%), Possible (41-60%), Unlikely (11-40%), and Highly Unlikely (less than 11%).
Here is a summary of the risk likelihood categories:
By considering these factors and using a risk assessment matrix, you can accurately calculate risk scores and make informed decisions about risk mitigation strategies.
Easy Prioritization
Easy Prioritization is a must-have for any business looking to manage risks effectively. By using a risk matrix, you can prioritize the most severe risks your company faces.
A risk matrix is a powerful tool that allows you to visualize and prioritize risks based on their likelihood and impact. This helps you identify the most pressing threats to your business and plan for them.
You can rate and color-code these risks in a risk assessment matrix, making it easy to identify the most critical risks. This is especially important for operational risks, such as major reputational damage due to a breach of private data, or an excessive increase in operating costs due to a natural catastrophe.
To prioritize risks effectively, compare the different risk rankings to the risk criteria, such as likelihood and impact. This will help you identify the risks that pose the highest likelihood and impact, and create a risk assessment plan to mitigate them.
Here's a simple way to think about it: if a risk has a high likelihood and high impact, it's likely to be a top priority. On the other hand, if a risk has a low likelihood and low impact, it may not be as critical.
By following this approach, you can prioritize your risks effectively and allocate your resources to the most pressing threats. Remember to update your risk assessment matrix regularly to reflect changes in your business environment.
Risk Assessment and Management
A risk assessment matrix is a visual tool that helps you identify and prioritize potential risks affecting your business. It's based on two intersecting factors: the likelihood of a risk event occurring and the potential impact it will have.
Using a risk assessment matrix, you can categorize risks as high, moderate, or low based on their likelihood and severity. For example, a supply-chain disruption caused by the COVID-19 pandemic might be classified as a high-level risk due to its high probability of occurring and significant impact on the business.
A 5×5 matrix is a common approach, where 1 is extremely low-risk and 5 is extremely high-risk, providing more insight into levels of severity and helping companies allocate resources more efficiently.
Targeted Management Strategy
A targeted management strategy is key to mitigating risks that have the biggest impact on your business. By focusing on the highest risks, you can benefit your overall business strategy.
The risk assessment matrix helps you identify potential risks and their severity, enabling proactive measures to mitigate impacts on the project's success. This systematic approach allows you to plan for Murphy's law, which is inevitable: what can go wrong, will go wrong.
A cost risk that significantly escalates the project cost would have a severe impact and requires a targeted management plan. This means planning for cost risk due to factors like scope creep will ensure a project's success.
The risk landscape is constantly evolving, and the risk assessment matrix should be updated multiple times a year to reflect the changing risk environment. Failure to update the risk assessment strategy could result in missing emerging risks that may disrupt business objectives and continuity.
By using a risk assessment matrix for risk management, you can reduce not only the likelihood of risks but also the magnitude of their impact on business operations.
Step 3: Assess
Assessing risks is a crucial step in the risk assessment process. It involves evaluating the likelihood and potential impact of each identified risk. Most organizations use a predefined scale to assess severity, with common scales including a 3-part scale (High, Moderate/Medium, Low) or a 5×5 matrix (extremely low-risk to extremely high-risk).
To assess risks, you need to consider both the likelihood and impact of each risk. The likelihood of a risk occurring can be categorized as Highly Likely (91% or more), Likely (61-90%), Possible (41-60%), Unlikely (11-40%), or Highly Unlikely (less than 11%). The impact of a risk can be categorized as Major, Significant, Moderate, or Minor.
A risk assessment matrix is a useful tool for visualizing the probability versus the severity of a potential risk. It helps you prioritize different risks and develop an appropriate mitigation strategy. By plotting risks on the matrix, you can quickly identify which risks require the most attention.
Here are some common risk assessment matrix categories:
- High risk: High likelihood and high impact
- Medium risk: Medium likelihood and medium impact
- Low risk: Low likelihood and low impact
Organizations can also use a 5×5 matrix to assess risks, with categories ranging from Extremely Low-Risk to Extremely High-Risk. This provides a more granular approach to risk assessment and can help companies allocate resources more efficiently.
Remember to update your risk assessment matrix regularly to reflect changes in the risk environment. This will help you identify emerging risks and ensure that your risk management plan remains effective.
