Residual risks are those that remain after implementing risk response strategies. In this scenario, the primary risk is a major power outage that could lead to the failure of the digital platform hosting the new product database. The financial institution has mitigated this risk by installing backup power generators. However, the possibility of a power outage still exists, and the effectiveness of the backup generators cannot be guaranteed with absolute certainty. Therefore, the remaining risk, despite the mitigation measures, is classified as residual risk.
