Question

Your organization uses the curated detection rule set in Google Security Operations (SecOps) for high priority network indicators. You are finding a vast number of false positives coming from your on-premises proxy servers. You need to reduce the number of alerts. What should you do?

Options

  • AConfigure a rule exclusion for the network.asset.ip field.
  • BConfigure a rule exclusion for the principal.ip field.
  • CConfigure a rule exclusion for the target.domain field.
  • DConfigure a rule exclusion for the target.ip field.

Explanation

Since the false positives are originating from your on-premises proxy servers, you should exclude their IPs from triggering alerts. In Google SecOps curated detections, the network.asset.ip field represents the IP address of the internal asset generating traffic. Configuring a rule exclusion on this field ensures that alerts from the proxy server IPs are suppressed, reducing false positives without affecting other detections.
