What should an IS auditor recommend if a new application patch is available but deemed unnecessary?

• A. Apply the patch without testing first.
• B. Implement a host-based intrusion detection system.
• C. Modify firewall rules to protect the application server.
• D. Assess the overall risk before deciding on the patch.

Answer: (D)

The recommendation to assess the overall risk before deciding on applying a new application patch is crucial for several reasons. An effective patch management process requires considering both the potential vulnerabilities that the patch addresses and the context in which the application operates. By assessing the overall risk, the auditor can evaluate factors such as the severity of the vulnerabilities, the likelihood of exploitation, the business impact, and the application's role within the organization's ecosystem. It allows the organization to make an informed decision about whether the patch is necessary, taking into account the potential disruption that could be caused by applying the patch and whether that risk is outweighed by the potential security benefits. Additionally, the patch may introduce unforeseen issues or conflicts with existing systems, making it vital to understand the implications of applying it. Thus, assessing overall risk aligns with best practices in information security and risk management, ensuring that the organization makes data-driven decisions about its IT security posture. This careful evaluation is particularly important in a dynamic environment where priorities may shift based on the latest threat intelligence and organizational needs.
