Implementing enhanced failure detection and backup systems is a risk reduction response because management is taking action to lower the likelihood or impact of data loss, corruption, processing failure, or system unavailability. Risk reduction involves designing and implementing controls to bring risk within the organization’s tolerance. Failure detection helps identify errors or system problems quickly, while backup systems support recovery and preservation of data integrity. Option A is incorrect because risk acceptance means management knowingly takes no additional action beyond existing controls. Option B is incorrect because risk sharing involves transferring or distributing risk, such as through insurance, outsourcing, or contractual arrangements. Option C is incorrect because risk avoidance means discontinuing the activity that creates the risk. Here, the organization continues operations but strengthens controls, so Option D is correct.
