Infrastructure TLS/SSL Guides

Harden the control plane of your infrastructure stack. These guides cover TLS for container runtimes, secrets management, monitoring systems, time synchronization, and more.

Chrony

NTP server with Network Time Security.

Docker

Container runtime and platform.

Grafana

Open-source monitoring and dashboards.

NTPsec

Security-hardened NTP with NTS support.

Node.js

JavaScript runtime with built-in TLS.

OpenLDAP

Open-source LDAP directory server.

Prometheus

Open-source monitoring and alerting toolkit.

Vault

HashiCorp secrets management platform.

About These Guides

Infrastructure tools — container runtimes, monitoring systems, time servers, secret stores — often expose unauthenticated management APIs by default. An exposed Docker daemon socket or Prometheus endpoint can give an attacker full control over your environment without touching the application layer.

These guides focus on locking down internal APIs with mutual TLS (mTLS), where both the server and client present certificates. This provides strong identity verification without relying on network segmentation alone.
