Description
Organizationally defined security policy filters include, dirty word filters, file type checking filters, structured data filters, unstructured data filters, metadata content filters, and hidden content filters. Configuration and enforcement of administrator privileges ensures only authorized users have access to certain commands and functions on the IDPS. This control can be met by assigning the privilege to enable or disable security policy filters to privilege groups and then assigning users to these groups. Authorization to add, modify, or delete security policy filters must require the highest privilege level. If system administrators cannot be configured with different security privileges, then need-to-know cannot be enforced.
