Process of Obtaining and Managing Multi Domain SSL certificates

• Choose a reputable CA: Consider price, validation levels, support, and brand.
• Select a certificate type: DV (quick & cheap), OV (more trust), or EV (highest trust).
• Specify domains: List all domains and subdomains you want to secure.
• Generate a CSR: Create a CSR on your server (hosting providers often offer tools).
• Purchase & Validation: Buy the certificate and submit your CSR. The CA will verify your ownership.
• Receive & Install: Download and install the certificate and private key on your server.

Managing a Domain SSL Certificate:

• Renewals: Set up reminders or automate renewals to avoid expiration.
• Monitoring: Regularly check certificate status to ensure validity and trust.
• Changes: Reissue the certificate with an updated SAN list if domains are added/removed.
• Revocation: Use the CA’s process to invalidate the certificate if needed.

Best Practices for Implementing Multi Domain SSL Certificates

Prioritise careful planning when selecting domains to include in the Domain SSL certificate. Ensure that all relevant domains are covered while avoiding unnecessary inclusions.

2. Regular Certificate Audits:

Conduct regular audits to review the domains covered by the Domain SSL certificate. This ensures that the certificate remains up to date, including relevant domains, and removing any no longer in use.

3. Optimal Certificate Lifespan:

Choose an appropriate lifespan for this certificate. While longer durations reduce administrative overhead, consider the dynamic nature of online environments and security best practices.

4. Secure Key Management:

Implement secure key management practices, including the protection of private keys associated with the Domain SSL certificate. Use hardware security modules (HSMs) for added security.

5. Stay Informed on Industry Standards:

Stay informed about the latest industry standards and security protocols. Regularly update the certificate to comply with evolving security requirements and best practices.
