Which role is the highest level of access among the provided options?

The role of "sn_si.admin" represents the highest level of access among the provided options because it typically encompasses the most extensive permissions and capabilities within the system. Admin roles generally grant users full control over configurations, settings, and user management, allowing them to perform a wide range of tasks that are crucial for maintaining and securing the system.

In contrast, the other roles suggest a more limited scope of access. For instance, "admin" might imply administrative functions but not necessarily the specific authority tied to the SI (Security Incident) module. "sn_si.manager" likely pertains to managerial permissions that focus on oversight and coordination rather than direct administrative control, while "sn_si.basic" is likely associated with standard user functionalities that do not include elevated privileges. Each of these roles has specific purposes tailored to various levels of responsibility within the security incident response processes, but none offer the comprehensive access implied by "sn_si.admin."
