Identify the role that provides the basic security access level.

The role that provides the basic security access level is identified as "sn_si.basic." This role is specifically designed to grant users fundamental access rights needed to perform essential tasks within the security incident response framework. Users assigned this role typically have the capabilities necessary to view incidents, access basic functionalities, and perform actions related to their responsibilities without the elevated permissions that come with roles like admin or manager.

In the context of security incident response, having a distinct role for basic security access is crucial for ensuring that individuals only have the permissions they need to fulfill their job functions while maintaining overall security. Higher roles, such as admin or manager, offer more extensive rights and responsibilities, which are not suitable for all users and should be restricted to prevent unauthorized access to sensitive data or critical system functions.
