What is the BEST method to ensure an eDiscovery analyst can only search but not change settings in hosted file shares?

The best method to ensure an eDiscovery analyst has the ability to search but not change settings in hosted file shares is to implement Role-Based Access Control (RBAC). RBAC is a systematic approach to managing user permissions based on their assigned roles within an organization. By defining roles with specific rights and limitations, organizations can fine-tune access control, ensuring that users only have the privileges necessary for their job responsibilities.

In this scenario, assigning the eDiscovery analyst a role that includes search permissions while explicitly excluding the ability to modify or change settings creates a secure environment tailored to their needs. This minimizes risks associated with unauthorized changes and maintains the integrity of the hosted file shares.

Other options, such as Public Key Infrastructure (PKI), Single Sign-On (SSO), and Multi-Factor Authentication (MFA), serve different security purposes. PKI is primarily used for securing communications through encryption and digital signatures. SSO simplifies user management but does not itself restrict what actions a user can perform once authenticated. MFA enhances access security by requiring multiple verification methods, but it does not restrict permissions. Hence, for managing user capabilities specifically around searching and modifying settings, RBAC is the most appropriate choice.
