When using ASM REST to remove a signature set association from a policy (DELETE), the set is removed from all policies in the system.
All policies will lose their association to that signature set. This may leave some policies not enforcing all the Attack Signatures that they are expected to.
ASM REST is used to remove a signature set association from a policy. DELETE /mgmt/tm/asm/policies/<ID>/signature-sets/<ID>
A DELETE can be issued to the collection endpoint: /mgmt/tm/asm/policies/<ID>/signature-sets utilizing the $filter parameter to delete only the desired sets. Ex. DELETE /mgmt/tm/asm/policies/<ID>/signature-sets?$filter=id eq '<ID>'
When using ASM REST to remove a signature set association from a policy (DELETE), the signature set association is removed only from the desired policy and not from all policies in the system.
