Certified Information Systems Auditor Practice Exam

The appropriate immediate action when an IS auditor discovers unauthorized software on PCs is to report the findings and recommend measures. This approach is vital for several reasons.

Firstly, unauthorized software poses significant risks to the organization's security and compliance posture. It can lead to vulnerabilities, potential breaches, or exposure to malware that can compromise sensitive data and system integrity. By reporting the issue, the auditor ensures that management is aware of the potential risks and can take appropriate steps to mitigate them.

Secondly, recommending measures allows for a thoughtful discussion on how to address the issue. This could involve reviewing current policies regarding software installation, identifying the source of the unauthorized software, and implementing controls to prevent future occurrences. Immediate removal of the software without careful consideration may disrupt business operations and fail to address underlying issues, such as user awareness or policy enforcement.

Ultimately, open communication and a strategic approach not only support compliance and security efforts but also help create a more robust framework for software management within the organization.
