In a containerized environment, certificates and mTLS are critical in securing your infrastructure. Our guides take you through the step-by-step process of implementing a trusted certificate-issuing process to meet your security needs, leveraging cert-manager, Istio, HashiCorpVault, and CSR API as vital security tools.
Challenge
Certificates and mTLS are critical for securing communication in a containerized environment. They help ensure that the communication is secure, authenticated, and compliant. In addition, in many cases, both short-lived (ephemeral) and longer-lived certificates are required to balance the security and operational needs of the infrastructure.
Ephemeral certificates ensure that workload-to-workload communication between containers or microservices within a cluster is secure. These certificates are designed to be renewed frequently, every few minutes, hours, or days. Longer-lived certificates typically provide trust and authentication between infrastructure components, such as load balancers, API gateways, or Kubernetes controllers.
A well-designed PKI system should be able to handle both types of certificates and manage their lifecycle efficiently.
Solution
EJBCA PKI supports cert-manager and securing service meshes via Istio and generic TLS, providing engineers with tools to secure their containerized applications. Today, you can try:
EJBCA centralizes certificate management, providing a single control point for issuance, revocation, and renewal. This consistency and security extends across the entire containerized application environment, reducing the risk of security incidents and data breaches.
