What can result from failing to protect the integrity of the PKI?

Failing to protect the integrity of the Public Key Infrastructure (PKI) can indeed lead to disciplinary actions. This is because integrity in PKI is vital to ensure that keys and certificates are valid and have not been tampered with. If the integrity is compromised, it can lead to unauthorized access, data breaches, or fraud. Organizations are responsible for safeguarding sensitive information and adhering to regulatory compliance standards. When incidents occur due to negligence in managing PKI, it may result in disciplinary measures directed towards individuals responsible for the PKI management or towards the company for not meeting compliance or security standards.

Other options suggest outcomes that do not align with the implications of a compromised PKI. Increased operational efficiency and improved network security are unlikely since integrity breaches typically cause disruptions and vulnerabilities. Enhanced user satisfaction would also be compromised, as users rely on the security and trustworthiness of digital certificates to engage with services securely.
