Ops Cert Checkv1.0.1

System administrators regularly validate SSL/TLS certificates across servers using OpenSSL and keytool commands. This scenario covers checking PEM/CRT/JKS certificates for expiry dates and issuer info, both locally and remotely for Nginx and game servers.

Standard operating procedure for replacing SSL certificates on Nginx web servers, reverse proxies, and CDN frontends. Includes file replacement, configuration validation via nginx -t, graceful reload, and verification.

Collaborative process between ops and dev teams to update Java KeyStore certificates for game servers. Ops provides cert and key, dev compiles JKS, ops uploads, and game server auto-replaces on next update, verified by requesting port+3.

Automated wildcard certificate issuance for self-managed services using ACME protocol and DNS-01 challenge. Involves certbot with DNS plugins (Alibaba Cloud, Cloudflare, Route53), DH parameter generation, Nginx integration, and cron-based auto-renewal.

Incident response for expired certificates causing business impact. Immediate actions include identifying affected domains, contacting responsible parties, replacing certificates and reloading Nginx, then implementing preventive measures like monitoring and alerting 30 days before expiry.

Offer as-a-service automated certificate lifecycle management including validation, renewal, and emergency replacement. Target SMBs lacking in-house ops expertise. Revenue via monthly subscription per domain or per server.

Integrate these SOPs into CI/CD pipelines and monitoring tools for enterprise clients. Provide consulting for custom automation (e.g., JKS compilation scripts, certbot hooks). Revenue from professional services and tool licensing.

Audit certificate posture and compliance (e.g., PCI-DSS, SOC2) for organizations. Offer remediation packages including emergency response, monitoring setup, and process documentation. Revenue per audit engagement and implementation project.
