What is the most appropriate first action when a monitoring system flags a security exception?

When a monitoring system flags a security exception, the most appropriate first action is to validate the exception. This step is crucial because it ensures that the flagged security event is genuine and not a false positive. Monitoring systems can often generate alerts based on patterns or changes that may not necessarily indicate a security breach. Therefore, validating the exception helps determine whether the alert is legitimate, which informs any subsequent actions.

Once the exception is validated and confirmed as a true security issue, other actions, such as escalating the incident, updating the risk register, or activating a risk response plan, can be considered based on the context and severity of the exception. However, without first validating the exception, any further actions taken could be premature or unnecessary, potentially leading to wasted resources or inappropriate responses. Validating the exception lays the groundwork for an effective incident management process.
