An IPS profile is a set of signatures relevant for protecting certain services. The administrator can create the desired number of IPS profiles to protect various services. It is recommended to limit the number of signatures in the profile only to those that are necessary for protecting the service. For example, to protect a service that uses the TCP protocol, you should not add signatures developed for UDP. A large number of signatures increases the traffic processing time and CPU load. For more details on creating and using IPS profiles, see the section Intrusion Detection and Prevention System.
