What should a TA do to maintain the integrity of the PKI?

To maintain the integrity of the PKI, following established security protocols is crucial. These protocols are designed to ensure that all processes related to public key infrastructure, including certificate issuance, renewal, revocation, and key management, are secure and compliant with regulatory and organizational standards. Adhering to these protocols helps to protect the system from unauthorized access, data breaches, and other potential vulnerabilities.

Established security protocols outline the necessary steps for safeguarding sensitive information and ensuring that the PKI operates effectively and securely. By diligently following these protocols, Trusted Agents contribute to the overall security posture of the organization, preserving the trust in the PKI system, and ensuring that cryptographic operations are carried out appropriately. This creates a reliable environment where users can confidently rely on the authenticity and integrity of communications secured by PKI.

The other options do not directly support the core objective of maintaining PKI integrity. Isolating from other staff might limit collaboration and communication, which are important for identifying vulnerabilities. Only working during office hours could restrict effective response times for incidents outside those hours, and while open communication is important, it doesn’t directly ensure security.
