Shift Kubernetes Cluster Security Left - DevSecOps
Empowering DevOps and security teams with continuous security for workloads running on Kubernetes
Alcide Kubernetes Advisor Pipeline Integrations
Alcide Advisor is an agentless service for Kubernetes audit and compliance that’s built to ensure a frictionless and secured DevSecOps workflow by layering a hygiene scan of Kubernetes cluster and workloads early in the development process and before moving to production.
With Alcide Advisor, you can cover the following security checks:
- Kubernetes infrastructure vulnerability scanning.
- Hunting misplaced secrets, or excessive priviliges for secret access.
- Workload hardening from Pod Security to network policies.
- Aspen Mesh (Istio) security configuration and best practices.
- Ingress Controllers for security best practices.
- Kubernetes API server access privileges.
- Kubernetes operators security best practices.
- Deployment conformance to labeling, annotating, resource limits, and much more.
Use Case Examples
Hunting Misplaced Secrets, or Excessive Secret Access
The Kubernetes secret object is designed to store and manage sensitive information, such as passwords, OAuth tokens, and SSH keys. Placing this information in plain text or in the wild (such as configMaps) makes it easily exposed to unauthorized users, and is a greater risk for your Kubernetes and cloud provider environments.
Alcide Advisor scans for any secrets, API keys, and passwords that may have been wrongfully misplaced in pod environment variables, as well as in configMaps. In addition, it verifies the use of Role-based Access Control (RBAC) permissions that defines who can read secret objects.
Scan for Kubernetes Vulnerabilities
While Kubernetes drastically simplifies the orchestration of your most sensitive containerized environments, it’s not bulletproof to critical security vulnerabilities that require quick detection and response.
An example of a serious vulnerability that was recently found is the privilege escalation vulnerability, tracked as CVE-2018-1002105. This vulnerability allows users, through a specially crafted request, to establish a connection through the Kubernetes API server and send arbitrary requests over the same connection directly to that backend. It was authenticated with the Kubernetes API server’s TLS credentials that were used to establish the backend connection.
Alcide Advisor scans your cluster for known vulnerabilities on the master API server and worker node components, including container runtime. This has great benefit for teams using both managed clusters like Kops, AKS-Engine or the managed Kubernetes services like Microsoft Azure Kubernetes Service (AKS).
The App-formation feature, which requires registration, allows you to generate a baseline profile based on a specific cluster - subsequent scans will return only issues that deviate from the baseline. This helps DevOps to focus only on relevant issues and assets that require attention.
