DNS Security Extensions (DNSSEC) enhance the security of the Domain Name System (DNS) by providing authentication and data integrity. As part of maintaining a secure DNS environment, it's important to periodically perform DNSSEC key rollovers. This knowledge base provides comprehensive information on the DNSSEC key rollover process in WHM cPanel.

Understanding DNSSEC Key Rollover

What is DNSSEC Key Rollover?

DNSSEC key rollover is the process of replacing the current DNSSEC key pair with a new one to maintain security. This is important to prevent cryptographic weaknesses that may arise over time.

Importance of DNSSEC Key Rollover

1. Security: Regular key rollovers help maintain the security and integrity of DNS data.

2. Compliance: Adherence to best practices and industry standards is crucial for DNS security.

WHM cPanel Tools for DNSSEC Key Rollover

1. DNSSEC Management Interface

In WHM cPanel, users can manage DNSSEC settings for their domains via the DNSSEC Management interface.

2. WHM API Functions

WHM provides API functions that allow users to manage DNSSEC settings programmatically, which can be useful for automation.

Performing a DNSSEC Key Rollover

Step 1: Log in to WHM

1. Open a web browser and navigate to your WHM login page (usually https://yourdomain.com:2087).

2. Enter your WHM username and password.

Step 2: Accessing DNSSEC Management

1. In WHM, navigate to Home > DNS Functions > DNSSEC Management.

2. Locate the domain for which you want to perform a key rollover.

Step 3: Initiating the Rollover

1. Click on the domain name to access the DNSSEC management options.

2. Find the section labeled 'Key Functions' or similar.

3. Click on the option to initiate a key rollover.

Step 4: Confirming the Rollover

1. Follow the prompts to confirm the key rollover.

2. If prompted, provide any necessary authentication or verification information.

Step 5: Monitoring the Rollover

1. After initiating the rollover, monitor the DNSSEC status for the domain.

2. Pay attention to any status messages or notifications regarding the rollover process.

Verifying DNSSEC Key Rollover

DNSSEC Analyzer Tools

1. DNSViz: Provides a visualization of the DNSSEC chain of trust and can help identify any issues with the rollover process.

2. DNSSEC Debugger: Analyzes DNSSEC configurations and can detect problems related to key rollovers.

DNSSEC Key Check

1. Check DS Records: Ensure that the DS (Delegation Signer) records in the parent zone have been updated to reflect the new DNSSEC keys.

2. Verify DNSKEY Records: Confirm that the DNSKEY records for the domain have been updated with the new key.

Reviewing DNSSEC Status

1. In WHM, navigate to Home > DNS Functions > DNSSEC Management.

2. Check the status of the domain to ensure that DNSSEC is active and that the key rollover was successful.

Troubleshooting DNSSEC Key Rollover

Common Issues

1. Propagation Delays: Changes in DNS settings, including key rollovers, can take time to propagate across the internet.

2. Misconfigured DNSSEC Records: Review DNSSEC records to ensure they are correctly configured.

DNSSEC Debugging Tools

1. DNSSEC-Tools: Provides a suite of tools for debugging and testing DNSSEC configurations.

2. Online DNSSEC Tools: Various online tools are available for checking DNSSEC configurations and troubleshooting.

Conclusion

Performing DNSSEC key rollovers is a crucial aspect of maintaining a secure DNS environment. By following the guidelines provided in this knowledge base, you can efficiently initiate and verify key rollovers in WHM cPanel. Regular monitoring and troubleshooting will help ensure the continued security and integrity of your DNS configurations.
