Abstract

You can triage, investigate, and take actions on alerts from the Alerts page.

All alerts are displayed on the Alerts page. Use the following steps to investigate and triage the alert:

  1. Review the data shown in the alert such as the command-line arguments (CMD), process info, etc.

  2. Analyze the chain of execution in the causality view.

    When the app correlates an alert with additional endpoint data, the Alerts table displays a green dot to the left of the alert row to indicate the alert is eligible for analysis in the causality view. If the alert has a gray dot, the alert is not eligible for analysis in the causality view. This can occur when there is no data collected for an event, or the app has not yet finished processing the EDR data. To view the reason analysis is not available, hover over the gray dot.

  3. If deemed malicious, consider responding by isolating the endpoint from the network.

  4. Remediate the endpoint and return the endpoint from isolation.
