Intelligence Security Events

You can configure Intelligence to trigger an alert when specific events occur in your cloud or cluster network. You or other recipients receive this alert as an email or as a different type of notification, so that you can respond to the event almost immediately.

To receive alerts, you must set up a policy. The policy includes a ruleset with specific Intelligence alert definitions, which are applied to selected cloud environments (VPCs) or KubernetesClosed Kubernetes, often abbreviated as “K8s”, orchestrates containerized applications to run on a cluster of hosts. clusters. With this policy, you associate a notification that specifies where you want to receive the alerts. Intelligence includes a number of preconfigured, CloudGuard-managed rulesets and policies.

In the Intelligence menu, you can set up your rulesets and policies.

Benefits

  • Automatic and continuous monitoring of your cloud environments and clusters based on queries configured for your enterprise needs

  • Automatic generation of near real-time alerts based on specific events and thresholds, issued to user-configured notification targets

  • Built-in rulesets that cover many of the same enterprise needs, to apply to your environments and Kubernetes clusters out-of-the-box
