Conducting vulnerability scans is the best way for a risk practitioner to validate the effectiveness of a patching program. Vulnerability scans are automated tools that identify and report on the vulnerabilities in a system or network, such as missing patches, misconfigurations, or outdated software. Vulnerability scans can help the risk practitioner to verify that the patches have been applied correctly and consistently, and that there are no remaining or new vulnerabilities that need to be addressed. Conducting penetration testing, interviewing IT operations personnel, and reviewing change control board documentation are also useful methods to evaluate the patching program, but they are not as comprehensive, objective, or timely as vulnerability scans.

According to ISACA, a risk register is a tool to record and track the identified risks, their ratings, responses, and status. The primary purpose of a risk register is to provide a centralized view of risk for the organization, as it enables the consolidation, communication, and reporting of risk information across different levels, units, and functions. A risk register can also support the risk management process, such as risk identification, assessment, treatment, monitoring, and review.
