1. Information Technology Auditing: IT auditing encapsulates the complete assessment of IT systems, their infrastructure, and controls. This ensures that the internal auditor manages the confidentiality, integrity, and availability of resources. Certified internal auditors also evaluate the effectiveness of cybersecurity measures. Including but not limited to encryption, network security, and access control to identify the vulnerabilities that could be exploited by malicious actors.  
2. Risk Management: Cybersecurity risk management consists of identifying, assessing, and responding to possible risks for an organization’s systems and networks. The certified internal auditor examines whether appropriate risk management policies have been set up, implemented, and maintained within the company’s departments. They also verify controls related to cyber threats like data breaches, malware attacks or unauthorized persons gaining access to sensitive information are in place and effective. They also evaluate the organization’s perception towards risks, tolerance levels, and strategies followed when responding to them so that there can be an alignment with its objectives on securing information and systems against possible attacks as well as requirements from various laws or regulations concerning this matter.
3. Fraud Examination: The focus of fraud examination is on the detection, investigation, and prevention of fraudulent activities, such as cyber fraud and financial crimes. In-depth knowledge of fraud examination possessed by internal auditors is utilized to evaluate the efficiency of anti-fraud measures, carry out forensic analysis of suspicious transactions, and provide recommendations aimed at reducing threats in the digital ecosystem.

The CIA triad symbolizes a fundamental principle in cybersecurity which when considered collectively influences the formulation of organizational security policies. When assessing the needs and use cases for prospective new goods and technologies as part of the internal auditing practice, the trinity enables organizations to ask targeted questions about how value is delivered in those three core areas.
