Once a vulnerability has been identified, what factor is crucial in determining its risk rating?

The likelihood of occurrence and severity of impact is a critical factor in determining the risk rating of a vulnerability because it provides a comprehensive assessment of both how often the vulnerability might be exploited and the potential consequences if it is exploited.

Evaluating the likelihood gives insight into how probable it is that the vulnerability will be leveraged by an attacker or result in a compliance breach. Coupled with this, assessing the severity of impact helps gauge the potential consequences, which could range from data loss to significant financial penalties, reputational damage, or even harm to patients.

By combining these two elements—likelihood and severity—you can arrive at a more informed understanding of the risk the vulnerability poses to an organization. This dual assessment allows for prioritization in risk management and resource allocation to mitigate the vulnerability effectively.

In contrast, focusing solely on factors such as the severity of financial loss, duration of the risk, or the number of affected patients does not provide as rounded a viewpoint. For instance, financial loss might be significant, but if the likelihood of the vulnerability being exploited is low, the overall risk might not warrant immediate action. Similarly, the number of affected patients can indicate scope but does not inherently reflect the critical assessment of how likely a breach is to happen or how severe
