In this section, we consolidated the essential steps for hardening your Consul data center using TLS:
Focus AreaKey Takeaways
Consul Security & Threat ModelOverview of common attack vectors and Consul’s defense mechanisms.
Secure Component RolesRoles of servers, clients, and proxies in maintaining a secure environment.
Certificate Types for TLSDifferences between internal CA, external CA, and node certificates.
TLS Encryption SettingsConfiguration of gossip encryption, RPC/TLS, and ACL integration.
Rotate your certificates regularly and store them in a secure location to minimize the risk of credential compromise.
The image outlines objectives related to secure agent communication, focusing on understanding Consul security, differentiating certificate types for TLS encryption, and understanding TLS encryption settings. It also includes a difficulty level indicator.
Thank you for completing this objective. With a solid grasp of Consul’s security model, certificate management, and TLS configuration, you’re ready to deploy a fully encrypted and resilient Consul cluster.
