Question: What is the recommended timing for renewing a Security Edge Gateway (SEG) CA or Transport Layer Security (TLS) CA certificate in a Network Domain Security (NDS) Authentication Framework?
Option 1: Immediately after detecting a security breach involving the old certificate.
Option 2: Before the expiration of the existing SEG CA or TLS CA certificate.
Option 3: During scheduled network maintenance windows, regardless of the certificate's expiration date.
Option 4: After the old certificate has expired, to minimize downtime for certificate updates.
Explanation: Renewing the SEG CA or TLS CA certificate before the old one expires ensures uninterrupted security and authentication services within the Network Domain Security (NDS) framework. This preemptive approach prevents potential security vulnerabilities and service disruptions that could arise from an expired certificate, highlighting the importance of proactive management in telecom network security.
