Applies To: ThreatSync+ NDR
Policy alerts notify you of activity on your network that is unauthorized or unexpected. When you configure ThreatSync+ NDR policies to reflect the network access policies of your organization, each policy alert you receive indicates a policy violation that might be a threat to your organization.
When you first set up ThreatSync+ NDR, a subset of policies are activated by default. These are identified by the tag Level 1 and they automatically generate policy alerts. About 30 of the more than 75 available policies are included in Level 1. These default policy alerts reflect the threats and vulnerabilities that are most common and easiest to remediate. For more information, go to About ThreatSync+ NDR Policies and Zones.
For policy alerts that are based on machine learning, ThreatSync+ NDR builds a baseline of activity and generates a policy alert only when traffic varies from this baseline. If you receive too many policy alerts, or want to change the threat sensitivity, you can tune your policies. For more information, go to Policy Tuning.
Monitor Policy Alerts
Policy alerts show on the ThreatSync+ NDR Policy Alerts page. The ThreatSync+ NDR Policy Alerts page provides a centralized list of policy alerts for operators to review and respond to. To respond to policy alerts, you can manually block devices or block unauthorized access, and tune your policies to ignore future, expected activity.
You can also set up email notifications for the creation of policy alerts. For more information, go to Configure ThreatSync+ NDR Alerts and Notification Rules.
The ThreatSync+ NDR Policy Alerts page shows these details:
- Status — Status of the policy. The status can be Live or Not Active. If you click Live, the status changes to Not Active and the policy is deactivated. If you click Not Active, the status changes to Live and the policy is activated.
- Policy Name — Name of the policy. Click the policy name to view the Policy Alert Details page.
- Tags — Tags you define and apply to organize your devices, subnets, and organizations.
