Determining Risk Ratings in IT Audits: A Guide for Professionals
In the realm of IT auditing, assigning a risk rating to a finding is both an art and a science, essential for prioritizing actions and mitigating potential challenges. As an IT auditor seeking to refine your approach, understanding the criteria used to determine whether a finding should be classified as High, Medium, or Low risk is crucial.
Evaluating Factors for Risk Ratings
When it comes to assigning risk ratings during an internal Audit, several critical factors usually guide the decision-making process. Below are some key considerations typically employed by Audit teams:
-
Financial Impact: One of the primary considerations is the potential financial repercussion of the finding. This involves evaluating how significantly the issue could affect the organization’s bottom line if left unaddressed.
-
Security Risk: Assessing the potential security implications is another pivotal aspect. This entails determining the level of threat the finding poses to the organization’s data integrity, confidentiality, and overall cyber safety.
-
Experience and Judgement: Sometimes, the rating may also involve professional judgment based on past experiences. While data-driven approaches are essential, the auditor’s insight and intuition play a vital role in identifying nuances that might not be immediately apparent through metrics alone.
Best Practices for Assigning Ratings
To ensure that risk ratings are consistent and reflective of the true nature of findings, it’s important for your Audit team to develop a standardized process. Here are some strategies:
-
Develop Clear Criteria: Establish guidelines that clearly define what constitutes a High, Medium, or Low risk. This helps auditors make unbiased, transparent, and defensible decisions.
-
Collaborative Decision-Making: Engage multiple team members in the risk assessment to leverage diverse perspectives and expertise, thereby enhancing the accuracy of risk evaluations.
-
Continuous Review: Regularly revisit and update the risk rating criteria to reflect new threats, changes in the IT landscape, and insights gleaned from past audits.
By meticulously analyzing each finding through these lenses, and adopting a structured and informed approach, audit teams can aptly prioritize their findings, ultimately safeguarding the organization’s interests more effectively.

Determining the rating for an Audit finding is a crucial step in the internal Audit process as it helps prioritize issues based on their potential impact and urgency. In our department, we employ a structured and methodical approach to ensure consistency and objectivity when categorizing findings as High (H), Medium (M), or Low (L).
Impact and Likelihood Assessment: The core of our assessment process involves evaluating both the impact and likelihood of the identified risk. We consider the potential financial impact, reputational damage, operational disruption, legal implications, and compliance issues. Simultaneously, we assess how likely the risk is to materialize, based on historical data, current controls, and emerging threats.
Risk Matrix: We utilize a risk matrix to plot findings, where one axis represents the impact and the other the likelihood. This visualization aids in determining the overall risk level with clear demarcation between High, Medium, and Low ratings. A finding with high impact and likelihood would naturally fall into the ‘High’ category, for instance.
Contextual Analysis: The context in which an issue arises significantly influences its rating. For example, a security vulnerability in a critical system will likely be rated higher compared to a similar issue in a less sensitive environment. Understanding the business processes and how they relate to an organization’s broader strategic objectives is essential for accurate risk assessment.
Stakeholder Collaboration: We engage with key stakeholders, including business unit leaders and IT managers, to gain insight into the implications of the findings. This collaborative approach ensures that our ratings consider the perspectives and expertise of different departments, promoting a more holistic view of the risk landscape.
Benchmarking and Industry Standards: Utilizing industry benchmarks and standards, such as ISO, NIST, or COBIT, helps us anchor our findings against recognized best practices. It allows us to objectively compare our findings to known standards and adjust our ratings accordingly.
Professional Judgment: While quantitative measures and frameworks are essential, professional judgment plays a role in our decision-making process. Seasoned auditors bring experience and intuition to the table, assisting in interpreting data and trends that numbers alone might not capture.
Re-evaluation Mechanism: Our process includes a feedback loop where findings can be re-evaluated based on new information or changes in the business environment. It ensures that our ratings remain relevant over time and adjust to emerging risks or mitigation strategies implemented by the organization.
