How soon should a broken token be replaced by the ETA after notification?

In the context of Public Key Infrastructure (PKI) and token management, it is critical to have clear protocols for replacing compromised or broken tokens to maintain security and operational continuity. The correct response indicates that a broken token should be replaced within 24 hours after notification. This timeframe is essential to mitigate risks associated with unauthorized access that could result from a faulty or compromised token. If a replacement is not completed within this specified period, there is an increased danger of security breaches, disruptions in service, and potential data loss.

Timely replacement reinforces the integrity and reliability of the authentication mechanisms provided by PKI. While tokens may sometimes be functional beyond this timeframe, waiting longer can introduce vulnerabilities, especially in environments where security is paramount. This structured approach to token replacement reflects a proactive security posture and aligns with best practices in managing cryptographic tokens within a PKI framework.
