it’s crucial to understand the five risk rating levels in the field. Not only can this help you identify potential threats, but it can also be used to keep your organization safe from cyber criminals.

Imagine a situation where your company’s valuable data falls into the wrong hands. The consequences could be catastrophic, leading to the loss of confidential information, financial losses, and damage to the reputation of your organization. It’s a scary thought, but it’s a reality that we face every day in this technological age.

This is why it’s paramount to have a clear understanding of the five risk rating levels in cyber security. By understanding these levels, you’ll have an excellent grasp of how to protect your company’s data from getting into the wrong hands. So, let’s explore the five risk rating levels in cyber security and how they impact your organization.

What are the 5 risk rating levels?

Risk rating levels are used to categorize and prioritize potential threats facing an organization. There are five risk rating levels, each with their own corresponding likelihood of occurrence. The five risk rating levels are as follows:

  • Level 1: Highly Unlikely
  • Risks in this category are improbable and unlikely to occur.
  • Level 2: Unlikely
  • Risks in this category have a low probability of occurring.
  • Level 3: Possible
  • Risks in this category may occur under certain circumstances or conditions, but are not very likely.
  • Level 4: Likely
  • Risks in this category are probable and have a significant chance of occurring.
  • Level 5: Highly Likely
  • Risks in this category are almost certain to occur and require immediate attention and mitigation efforts.
  • It’s important for organizations to identify and assess potential risks and threats, and assign the appropriate risk rating level to each. This enables them to prioritize their mitigation efforts and allocate their resources effectively. By employing a systematic and structured approach to risk assessment, organizations can better protect themselves against potential harm and minimize the impact of any incidents that do occur.


    ???? Pro Tips:

    1. Determine Assessment Criteria: Before rating the risks, determine the assessment criteria. Define the factors that affect risk severity, such as financial loss, data damage, and reputational harm.

    2. Calculate the Probability of occurrence: Risk rating involves a calculation of probability and potential impact. Determine the likelihood of an event happening by examining all relevant data, such as historical data, industry trends, and threat intelligence.

    3. Define Impact Severity: Identify the severity of the potential impact of the risks based on the assessment criteria you defined earlier. For example, theft of personal data can significantly harm the organization’s credibility.

    4. Develop Risk Rating Scale: Create a rating system that includes all assessment criteria, probability, and impact severity. The rating scale should accommodate all the possible scenarios that the organization can face.

    5. Set Risk Tolerance Levels: Finally, define the risk acceptance level for senior management, stakeholders, and individuals directly impacted by the risks. Identify the appropriate course of action for different risk scenarios such as mitigation, transfer, sharing, or acceptance.

    Understanding Risk Rating Levels in Cyber Security

    In the world of cyber security, it is crucial to assess and understand the risks that your organization may be vulnerable to. One common method used to evaluate the level of risk is through utilizing a risk rating system. A risk rating system allows organizations to prioritize risks and allocate resources accordingly. There are five different levels of risk ratings, ranging from highly unlikely to highly likely. Here is a closer look at each risk level and how they can impact your organization.

    Level 5 Risk Rating: Highly Likely

    Risks that fall into the highly likely category are nearly certain to occur. This means that the threat actor has the capability and the intent to target your organization specifically. In the event that a highly likely risk occurs, the consequences can be severe and even catastrophic. For example, a highly likely risk could be a targeted phishing attack on your organization’s finance department. If successful, this could lead to a significant loss of money and reputation damage.

    Level 4 Risk Rating: Likely

    Risks that fall into the likely category have a high probability of occurring, although not as certain as risks in the highly likely category. A likely risk is one where the threat actor has demonstrated the capability and intent, but may not have targeted your organization specifically. An example of a likely risk could be a ransomware attack on the general employees of your organization. The attack is widespread and not targeted, but still has the potential to cause significant disruption and data loss.

    Level 3 Risk Rating: Possible

    Risks that fall into the possible category have a moderate probability of occurring, but the threat actor may not have the capability or the intent to target your organization. A possible risk is one that may be a part of a wider attack campaign, but your organization is not the primary target. An example of a possible risk could be a malware attack through an infected website that is visited by an employee of your organization. The risk is not targeted, but could still cause damage if the malware is able to infiltrate your organization’s network.

    Level 2 Risk Rating: Unlikely

    Risks that fall into the unlikely category have a low probability of occurring, but cannot be completely ruled out. An unlikely risk is one that the threat actor may be capable of, but has not demonstrated any intent to target your organization. An example of an unlikely risk could be an insider threat from an employee who has no malicious intent, but accidentally deletes important files or data.

    Level 1 Risk Rating: Highly Unlikely

    Risks that fall into the highly unlikely category have an extremely low probability of occurring. These risks are often hypothetical and theoretical, and have never been seen in practice. An example of a highly unlikely risk could be a cyber attack carried out by extraterrestrial beings. While it is important to consider these risks, most organizations will not allocate resources towards mitigating highly unlikely risks.

    Determining Appropriate Risk Rating Levels

    It is crucial for organizations to accurately assess the appropriate risk rating level for each potential threat. This is done by considering the likelihood and potential impact of the risk, as well as the organization’s resources and ability to mitigate the risk. It is important to note that an organization’s risk rating levels will be specific to their unique circumstances, and may be different from another organization’s.

    Mitigating Risks at Different Risk Rating Levels

    Once an organization has identified potential risks and assessed their risk rating levels, it is important to implement appropriate measures to mitigate these risks. Here are some examples of mitigation measures that can be taken at different risk rating levels:

    Level 5: Highly Likely

  • Implementing two-factor authentication for employees with high-level access
  • Consistently educating employees on the latest phishing tactics and how to identify them
  • Employing endpoint detection and response (EDR) software to quickly detect and respond to threats

    Level 4: Likely

  • Regularly backing up important data to mitigate the impact of ransomware attacks
  • Using strong encryption to protect sensitive data in case of a data breach
  • Conducting regular vulnerability assessments to identify and fix potential vulnerabilities before they can be exploited by attackers

    Level 3: Possible

  • Implementing email filters to prevent phishing emails from reaching employees
  • Limiting employee access to websites and external devices that may host malware
  • Ensuring all software and systems are regularly updated with the latest security patches

    Level 2: Unlikely

  • Implementing role-based access control (RBAC) to limit employee access to sensitive data
  • Conducting regular security awareness training for employees to help prevent accidental data loss or deletion
  • Regularly monitoring employee activities to detect potential insider threats

    Level 1: Highly Unlikely

  • Regularly monitoring the cyber security landscape to stay informed of emerging threats
  • Conducting tabletop exercises to prepare for the unlikely event of a highly unlikely threat occurring
  • Continually reassessing and updating risk rating levels as circumstances change

    In conclusion, understanding and mitigating potential risks is vital for any organization in order to protect sensitive information and ensure business continuity. By utilizing a risk rating system and implementing appropriate mitigation measures, organizations can proactively identify and address potential cyber threats.
