Over the past four years we’ve helped hundreds of organizations run reliable, secure, and compliant Kubernetes and Openshift clusters. Some of the key themes we’ve seen from organizations that have successfully grown their Kubernetes footprint are: they have immaculate labeling, understand how to leverage internal Kubernetes features to harden their platform, and understand what developers need access to and manage it with RBAC and namespaces. Even though you’ve probably seen all of these as best practices, being diligent that they always happen will take you a long way.
In the 2.2 version of Sysdig Secure we’ve released a set of features with bidirectional integrations between your Kubernetes or Openshift cluster and Sysdig Secure. The data from Kubernetes helps the workflows in Sysdig Secure follow the same procedures you’d use within Kubernetes for access control and analysis. While the vulnerability and configuration data from Sysdig Secure allows Kubernetes to become more advanced in the prevention of unwanted images running on the cluster.
Let’s dive into some of the new features in 2.2.
Kubernetes audit events
Adds new detections based on audit data from the Kubernetes API
Sysdig is the first cloud-native security provider to tap the recently released Kubernetes Audit Policy, creating an additional feed of events to monitor. Virtually all cluster management tasks are done through the API server; therefore, the audit log contains all changes made to the cluster. By tapping the kube-apiserver, Sysdig can alert administrators of suspicious and notable behavior. These alerts help users quickly identify incidents that could negatively impact the business and lets operators answer who did what, where, and when.
Service based access control
Sysdig Secure 2.2 introduces service based access control, providing customized reports and dashboards that give users access to only the information that is pertinent to them. The ability to control team privileges to hosts, namespaces, clusters, and deployments, exposes information only to those who need it, making it easier to respond to incidents and adding another layer of security by limiting exposure to information outside the scope of individual teams.
Kubernetes vulnerability management
Sysdig Secure 2.2 has added ability to natively integrate with Kubernetes admission controllers. Through mutating webhooks, Kubernetes can authenticate with Sysdig Secure to prevent unscanned or vulnerable images from being deployed on a cluster. This non-intrusive approach allows organizations to validate images at the Kubernetes level rather than the container-runtime.
Service oriented compliance
Leveraging Kubernetes labels to improve operations and reporting
With the introduction of Kubernetes resource-specific scheduling of CIS Compliance Benchmarks, Sysdig Secure 2.2 further eases the pain of measuring and enforcing compliance across a distributed environment. Scoping enables users to limit scans to specific Kubernetes resources, which saves time by limiting compliance checks to the logical entities that are important to auditors.
Integrating metrics for advanced reporting
For users who pair Sysdig Monitor with Sysdig Secure 2.2, they have access to more than 90 new metrics that are sent to the Sysdig platform. By viewing Sysdig Secure metrics with the Sysdig Monitor data on the same dashboards, enterprises gain visibility into the performance, health, compliance, and security posture of their environment on a single dashboard.
