Adding protection profiles to user groups | Fortinet IPS manual


IPS overview and general configuration	Using IPS sensors in a protection profile

Adding protection profiles to user groups

When creating a user group, select a protection profile that applies to that group. Then, when configuring a firewall policy that includes user authentication, select one or more user groups to authenticate. Each user group selected for authentication in the firewall policy can have a different protection profile, and therefore different IPS settings, applied to it.
