A IPS profile is a set of signatures relevant for the protection of certain services. Administrators can create any number of IPS profiles to protect various services. It is recommended that you avoid adding excessive signatures to profiles and use only signatures that are really important for security. For example, do not add UDP-specific signatures to a profile that protects a TCP-based service. When there are too many signatures, the system will be processing the traffic longer due to additional workload on the CPU. For more details on how to create and use IPS profiles, please refer to section Intrusion prevention system.
