What method is used to harden a CPM that is not part of an Active Directory domain?

The method used to harden a Central Password Manager (CPM) that is not part of an Active Directory (AD) domain involves applying an INF file. An INF file is a text file used for installing and configuring drivers or software in various Windows environments. It can contain settings that modify how the CPM operates and enhances its security posture when it's not integrated within an AD domain.

This method is particularly advantageous because it allows for batch configuration, ensuring consistency and efficiency in managing settings across multiple instances of CPM. Applying an INF file helps standardize security hardening measures that might otherwise require manual configuration or scripts, which can be error-prone and less manageable in larger environments.

Using alternative methods such as applying Group Policy Objects is specific to environments that are joined to Active Directory and does not apply in situations where CPM is not domain-joined. Similarly, although configuration scripts and manual registry changes can accomplish hardening, they may not be as comprehensive or standardized as using an INF file. INF files provide a structured approach to implementing security configurations, making them suitable for this particular scenario.
