SSL/TLS encryption is no longer optional for web servers. Beyond protecting sensitive data in transit, encrypted connections are increasingly expected by users and rewarded by search engines. Proper certificate management ensures uninterrupted encrypted service and prevents the embarrassment and security risk of expired certificates.
Certificate Types and Validation Levels
Domain Validated (DV) certificates verify only domain ownership and are issued quickly at low cost. Organization Validated (OV) certificates include verified company information in the certificate details. Extended Validation (EV) certificates require thorough vetting and display the organization name prominently in the browser, providing the highest level of trust for e-commerce sites.
Generate your private keys on the server where they will be used and never transfer them over unencrypted channels. Use at least 2048-bit RSA keys and configure your web server to prefer strong cipher suites. Disable SSLv2 and SSLv3 entirely, as both protocols contain known vulnerabilities that compromise the security of the connection.
Implement a certificate lifecycle management process that tracks expiration dates, renewal deadlines, and responsible administrators. Automated monitoring with alerts at 30, 14, and 7 days before expiration prevents unexpected outages. Consider using a certificate management tool that integrates with your monitoring system for centralized visibility across all your domains.
