Each sprint focuses on specific aspects of the cybersecurity audit, allowing for continuous improvement and adaptation.

Assemble a cross-functional team that includes internal auditors with a background in cybersecurity, compliance, and finance. This collaboration ensures that diverse perspectives are considered, and that the audit process benefits from the expertise of different individuals. Regular communication and collaboration within the team are essential for identifying and addressing cybersecurity risks effectively.

Each sprint of the audit should focus on a specific aspect of cybersecurity controls like design and operating effectiveness. At the end of each sprint, review the findings, gather feedback, and adjust the audit plan as needed. Engage with stakeholders throughout the audit process for a continuous feedback loop that ensures the audit remains aligned with the organization's needs and promptly addresses any emerging issues.

Leveraging and utilizing automation tools and technologies will help streamline the audit process. Automated security testing, continuous monitoring, and real-time reporting can enhance the efficiency and effectiveness of the audit. Additionally, these same tools will help with identifying vulnerabilities and assessing the organization's overall cybersecurity disposition more accurately.

By prioritizing high-risk areas and critical controls in the audit plan, agile auditing also allows for greater flexibility in adjusting priorities based on emerging threats. When organizations focus on the most significant risks they can allocate resources more effectively and mitigate potential cybersecurity threats.

Lastly, don’t forget to document the findings of each sprint and provide actionable recommendations for improving cybersecurity measures. This documentation should include identified gaps, weaknesses, and suggested corrective actions. Just as important, continuously monitor the implementation of recommendations and follow-up to ensure that necessary improvements are made. This ongoing action helps maintain the effectiveness of cybersecurity measures and enhances the organization's overall security posture.

What does the future of an agile audit methodology in cybersecurity look like?

Integrating the Global Internal Audit Standards Topical Requirements

In addition to implementing an agile methodology, the new Global Internal Audit Standards Topical Requirements are a significant development in the internal audit profession, providing clear expectations and a minimum baseline for auditing-specified risk topics, such as cybersecurity. These requirements are designed to enhance the consistency and quality of internal audit services, ensuring that internal auditors are well-equipped to address pervasive and evolving risks.

Purpose and structure of the Topical Requirements

The Topical Requirements are a mandatory component of the International Professional Practices Framework (IPPF) and are intended to provide a consistent, comprehensive approach to assessing the design and implementation of governance, risk management, and control processes in specific risk areas. A user guide accompanies each Topical Requirement to help internal audit functions implement the requirements effectively.

Key features of the Topical Requirements:

1. Minimum baseline for auditing: The Topical Requirements set a minimum baseline for auditing specified risk topics, ensuring that internal auditors have a clear and consistent framework to follow. This baseline helps auditors assess the effectiveness of governance, risk management, and control processes in particular risk areas.
2. Applicability: Internal auditors must apply the Topical Requirements in conformance with the Global Internal Audit Standards for assurance engagements when applicable. These requirements are applicable when a risk assessment identifies the topic as a subject of an assurance engagement in the internal audit plan or as an engagement request not on the original plan.
3. Documentation and retention: Evidence that each requirement in the Topical Requirement was assessed for applicability must be documented and retained. If certain requirements are excluded, a rationale must be provided and documented. This ensures transparency and accountability in the audit process.
4. Alignment with established frameworks: The IIA recognizes that organizations globally use various risk, control, and governance frameworks. Internal audit functions may apply these frameworks in conjunction with the Topical Requirements to ensure a comprehensive assessment.
