Risk Assessment
A risk assessment is a structured process for identifying things that could go wrong for an organization and analyzing the potential harm they could cause. The goal is to understand which risks matter most so the organization can decide how to address them. In a payment security context, it helps teams weigh threats to systems and data and prioritize their responses.
