In QRadar, what indicates the credibility rating of a log source?

In QRadar, the credibility rating of a log source is indicated by the integrity parameter. This parameter assesses the reliability of the data coming from the log source. A higher integrity value signifies that the logs are trustworthy and can be used with confidence for analysis and decision-making purposes.

Establishing the integrity of log sources is crucial for accurate security monitoring and incident response. When integrity is well-evaluated, it helps organizations prioritize alerts and focus on significant security events, effectively optimizing their security operations.

In contrast, the relevance parameter typically reflects the significance of the event in relation to the broader security context, while the impact parameter assesses the potential consequences of the event. The severity parameter gauges the urgency and seriousness of an incident, but these do not directly measure the credibility of the source itself. Therefore, the integrity parameter is the most appropriate choice for indicating the credibility rating of a log source in QRadar.
