Operator support: Simplifying Management and Deployment

KubeArmor v0.11 comes with robust operator support, making the installation, configuration, and management of KubeArmor instances a breeze. The KubeArmor Operator streamlines the deployment process, enabling you to efficiently set up and maintain KubeArmor across your Kubernetes clusters. Embrace simplicity and consistency in managing your security policies.

Elements of KubeArmor Operator design:

• Operator: The operator is the initial component that gets deployed as part of the helm-based installation. The job of the operator is to reconcile the current state of KubeArmor to its intended state.
• Snitch: Snitch is a job deployed by the operator to check what are the prevalent LSM (Linux Security Modules) and the container runtime on each of the nodes. Snitch then directs the KubeArmor daemonset to use these parameters to accordingly use the appropriate enforcer and container runtime primitives.
• bpf-containerd: This is essentially the KubeArmor daemonset that does most of the work from observability to policy enforcement. Note that the name of the daemonset is dependent on the underlying enforcer (bpf, apparmor) that is used and the container runtime that is detected.
• Relay: KubeArmor Relay connects to each of the daemonset and collects the alerts/telemetry/log and makes it available at a single GRPC endpoint. External services can connect to KubeArmor Relay to get the alerts/telemetry from a single point. Relay is available as a k8s deployment/service.
• Controller: KubeArmor controller reconciles the KubeArmor policies. One of the biggest advantages of KubeArmor is its use of k8s-native design for policy management. Users can enable disable policies at will by applying/deleting the policies at runtime. This enables a wide range of possibilities such as time-based policy activation.

OpenTelemetry

OpenTelemetry KubeArmor adapter converts KubeArmor telemetry data (logs, visibilty events, policy violations) to the openTelemetry format. This adds opentelemetry support to KubeArmor providing a vendor agnostic means of exporting KubeArmor’s telemetry data to various observability backend such as elastic search, grafana, signoz and a bunch of other opentelemetry adopters!

To enhance your observability capabilities, KubeArmor now seamlessly integrates with Open Telemetry. Gain unparalleled insights into container behavior and workload interactions through comprehensive telemetry data collection. With this integration, you’ll be equipped to make informed decisions, swiftly identify anomalies, and proactively address potential security threats.

Announcing k8tls (pronounced cattles): k8s service endpoints TLS best practices assessment

Security extends beyond containers. KubeArmor v0.11 introduces k8tls to bolster transport layer security within Kubernetes clusters. Safeguard your communications with enhanced encryption, safeguarding your data and ensuring the confidentiality of sensitive information.

K8tls is a k8s-native service endpoint scanning engine that verifies whether the endpoint is using secure communication and is using the right security configuration. K8tls deploys itself as a k8s job that scans/fingerprints k8s service endpoints to identify if TLS best practices are followed.
Primary features include:

• 🔒 Check if the server port is TLS enabled or not.
• 📃 Check the TLS version, Ciphersuite, Hash, and Signature for the connection. Are these TLS parameters per the TLS best practices guide?
• Certificate Verification
  • 💥 Is the certificate expired or revoked?
  • ✍️ Is it a self-signed certificate?
  • ⛓️ Is there a self-signed certificate in the full certificate chain?

KubeArmor as Canonical Microk8s Addon

Microk8s is a full embedded Kubernetes platform that is lightweight yet robust and scalable and is a perfect fit for edge, embedded scenarios. KubeArmor support for Canonical MicroK8s as a community addon is merged making microk8s more secure. Microk8s with KubeArmor brings enterprise grade security to lightweight edge kubernetes environments.

Kind and Minikube Compatibility

With this release, KubeArmor extends its compatibility to Kind and Minikube clusters, enabling you to effortlessly apply KubeArmor’s security policies to your local testing and development environments. Maintain consistency between testing and production while fortifying your workloads.

karmor profile

karmor logs tool provides raw telemetry out of the box. However, you may want to summarize the process, file, network, syscall events over a period of time. karmor profile introduces a way to handle the summarization. KubeArmor community followers might realize that the base profile feature was added in v0.8 release. v0.11 vastly improves the usability of the features, for e.g, by sorting the data based on process name, summarizing/aggregating well, adding syscall related event summarization etc.

EKS Addon published: Simplifing EKS deployment

Amazon EKS Anywhere allows installing and managing Kubernetes clusters on your own infrastructure, with optional support from AWS. EKS Anywhere supports full lifecycle management of multiple Kubernetes clusters that can operate completely independently of any AWS services. It provides open-source software that’s up to date and patched so you can have an on-premises Kubernetes environment that’s more reliable than a self-managed Kubernetes offering. EKS Anywhere is compatible with Bare Metal, CloudStack, and VMware vSphere as deployment targets.

Although EKS Anywhere can make cluster administration easier, the issue of protecting how Kubernetes namespaces, pods, workloads, and clusters interaction and access of shared resources remains an unsolved problem. It is imperative that workloads are protected at runtime since most of the attacks such as cryptomining, ransomware, data exfiltration, denial of service are manifest once the workloads are deployed in target k8s environment.

In line with the recommended safety guidelines for EKS, KubeArmor comprehensively fulfills these requirements. Getting up to speed on the Kubernetes threat environment proves to be difficult for security teams. New responsibilities for Kubernetes infrastructure and workloads lead to high overhead. Furthermore, ensuring that platform and application teams have consistency and complete visibility across environments for configurations and settings to fulfill AWS EKS security best practices can be difficult. KubeArmor helps you take care of most of these for you.

Streamlined Deployment: Updated Helm Chart

Deploying KubeArmor has never been smoother. The updated Helm chart simplifies the installation process, ensuring that you can effortlessly manage KubeArmor’s security policies across your Kubernetes clusters. Spend less time configuring and more time securing. Use of KubeArmor Operator greatly simplifies the auto detection of cluster components and deploying the kubearmor accordingly. For example, no more mounting of unwanted host mount points to just detect the container runtime in use.

Staying in Sync with Infrastructure: Terraform Updates

For those who embrace infrastructure-as-code, KubeArmor v0.11 offers updated Terraform integration. Seamlessly incorporate KubeArmor into your Terraform workflows, ensuring consistent security provisioning throughout your infrastructure.

Open source KubeArmor terraform provider from AccuKnox helps provision KubeArmor deployments, policies, and configuration at scale using Hashicorp Terraform.

Pushing Boundaries: Scale Testing with KubeArmor-Relay

Scalability is of paramount importance. One of primary hurdle to observability/monitoring solutions is its impact on runtime performance. With v0.11, we tested logging/telemetry components such as KubeArmor-Relay for scale of 100s of nodes. Through rigorous testing under varying workloads, KubeArmor v0.11 ensures unwavering performance even in the most dynamic Kubernetes environments.
