Managing your alerts and classifying true/false positives helps to train your threat protection solution and can reduce the number of false positives or false negatives over time. Taking these steps also helps reduce noise in your queue so that your security team can focus on higher priority work items.

For more information about suppressing alerts, see Manage Defender for Endpoint alerts. And, if your organization is using a security information and event management (SIEM) server, make sure to define a suppression rule there, too.
Indicators (specifically, indicators of compromise, or IoCs) enable your security operations team to define the detection, prevention, and exclusion of entities. For example, you can specify certain files to be omitted from scans and remediation actions in Microsoft Defender for Endpoint. Or, indicators can be used to generate alerts for certain files, IP addresses, or URLs.
We recommend using Full automation for automated investigation and remediation. Don't turn these capabilities off because of a false positive. Instead, use "allow" indicators to define exceptions, and keep automated investigation and remediation set to take appropriate actions automatically. Following this guidance helps reduce the number of alerts your security operations team must handle.
