Required options

You must define certain required options when creating custom signatures. Required options are name, service, and flow. Protocol is not a required signature option but we strongly recommend that you use the protocol option in your custom signatures.

Attack IDs may be a required option if you are using FortiManager. If you are configuring a customer signature directly on the FortiGate, FortiOS automatically generates attack IDs if you do not provide them. For the following FortiManager versions, FortiManager does not automatically generate attack IDs, so you must define attack IDs:

• 6.0.0 to 6.0.6
• 6.2.0 to 6.2.2
