Threat Management False Positive handling

False Positive

A newly deployed SIEM may generate alerts for harmless processes. Since each organization differs, some legitimate internal processes can be misidentified as threat activity. It is critical to tune it within the system so it operates effectively and lowers false positives. This matters greatly for reducing alert fatigue.

Note:Handling false positives is vital for security operations. A large volume of false positives can overburden security teams and lead them to possibly miss actual threats. In addition, repeated false alerts can make teams less responsive to alerts overall, raising the chance that real threats are overlooked.

Understanding the "False Positive" Tag

Within the Alert Management Module, users can tag alerts as False Positive. After an alert is tagged as a false positive according to specific conditions, the system will treat similar future alerts under those conditions as false positives and will not surface them as genuine threats.

Practical Example: False Positive Tagging

Consider a user who belongs to your organization. The Alert Management System may detect unusual activity based on specific conditions and raise alerts. However, because the organization knows this interaction is benign, those alerts are actually false positives.

To handle such a scenario, the organization can set a false positive rule:

Step-by-Step Guide to Create a False Positive Tag

  1. Navigate to the Alert Management Data Grid area of the Alert Management Module.

  2. Choose the alert from which you can extract the conditions to turn it into a false positive tag rule.

  3. Click on Create New Tag Rule.

  4. Among the available tags, choose False Positive.

  5. Give a name and a description to the Rule.

  6. Set the condition as Equals and type in the PC name.

  7. Save the rule.

💡*** Tip:**** Once this rule is saved, any alert generated from activity originating from that PC will automatically be tagged as a false positive, ensuring that the security team is not inundated with unnecessary alerts.*

Note:* By effectively managing false positives, organizations can streamline their threat detection and response processes, ensuring that genuine threats don't go unnoticed.*
