After an information systems audit revealing numerous findings, what is the best approach to address this?

The most appropriate approach to address the findings of an information systems audit is a risk mitigation plan. This plan is fundamental in systematically analyzing and managing the risks identified during the audit. A risk mitigation plan focuses on prioritizing the findings based on their potential impact and likelihood of occurrence and outlines specific actions to reduce risks to an acceptable level. This could involve implementing new controls, strengthening existing ones, or reallocating resources to better manage the identified risks.

The development of a risk mitigation plan is critical because it not only addresses the immediate issues brought to light by the audit but also establishes a proactive approach to ongoing risk management. By taking strategic steps to mitigate risks, an organization enhances its overall security posture and ensures compliance with relevant regulations and standards.

While a business impact analysis (BIA) is relevant, it primarily focuses on understanding the potential consequences of disruptive events rather than directly addressing the specific findings of an audit. An incident management plan deals with the response to security incidents post-factum, and revisions to information security procedures focus on updating existing protocols without necessarily addressing the identified risks in a structured manner. Therefore, choosing to create a risk mitigation plan aligns best with the requirement to effectively manage and respond to the findings from the audit.
