What should be done if a control is determined to be ineffective during monitoring?

When a control is determined to be ineffective during monitoring, the most logical and appropriate action is to implement alternative controls. The primary goal of risk management and security frameworks is to ensure that adequate protections are in place to mitigate risks. If an existing control doesn't function as intended, it leaves the organization vulnerable to potential threats.

Implementing alternative controls means identifying other mechanisms or strategies that can effectively reduce or manage the identified risk. This proactive approach ensures that the organization does not remain exposed to threats and demonstrates a commitment to maintaining security posture. Moreover, it aligns with the principles of continuous improvement, which are vital in information security practices.

In contrast, documenting audit findings solely serves the purpose of record-keeping and does not address the immediate gap in security. Ignoring the findings is irresponsible as it increases risk exposure. Considering a control’s ineffectiveness as low risk fails to recognize the severity of the shortcomings accurately, potentially leading to severe consequences if a security incident occurs. Thus, implementing alternative controls is a necessary step to maintain the integrity of the risk management framework.
