USM Anywhere enables you to make the sensorSensors are deployed into an on-premises, cloud, or multi-cloud environment to collect log and other security-related data. This data is normalized and then securely forwarded to USM Anywhere for analysis and correlation. drops future eventsAny traffic or data exchange detected by AT&T Cybersecurity products through a sensor, or through external devices such as a firewall. that match the rule. These events will be neither correlated nor stored. Through these rules, you are able to define which event data you are going to store in USM Anywhere. You will pay for the data you use.

Note: Filtering rules are not retroactive. The rule applies to future items and it does not apply to previous items, even if those items follow the rule.

Important: You can't use a correlation list when you create a filtering rule.

To create a filtering rule from the Events page

    Note: Keep in mind that the Sources or Destinations field needs to match the universally unique identifier (UUID) of the event or alarm. You can use the Source Name or Destination Name field instead.

    Important: Instead of using the equals and equals, case insensitive operators for array fields, AT&T Cybersecurity recommends the use of the in or contains operators.

    Note: If you need to add a property value that maps with a property key, you need to know the mapping of the field. See Determining the Mapping of a Field for more information.
