Implementing a file corruption detection tool as a risk response strategy will help to reduce the impact of future events, as it will enable the organization to identify and correct the corrupted files before they cause further damage or loss. A file corruption detection tool is a software that scans and verifies the integrity and validity of the files, and alerts the users or administrators of any anomalies or errors. This helps to minimize the disruption and downtime caused by the data corruption incidents, and to preserve the quality and reliability of the data. Implementing a file corruption detection tool will not reduce the likelihood of future events, as it does not prevent or mitigate the causes or sources of the data corruption incidents. It will not restore availability, as it does not recover or restore the corrupted files, but only detects them. It will not address the root cause, as it does not analyze or eliminate the underlying factors that lead to the data corruption incidents.
