Illigal Parameter addition as custom signature set wanted to Unblock

hello Team,

 

We have have created the custom signature set to allow this violation traffic but when we applied the newly created custom signature set it is still showing Block as properties when we assigned to the existing policy but i wanted custom signature set shall be only Learn & Alarm, no Block.

I will not be able to attached the screenshot for more details due to images not able to upload in forum.

Please help me to resolve this issue.

In the log event every time digits are changing in Parameter Name

 

Parameter LocationForm Data

Parameter Value

    Hi Manish,

    that's a bit unspecific description, sharing a bit more information about your policy could us to help you. 
    Can you show the custom signature you created and how/where you applied it? Also what kind of request is this, looks like JSON rather than "normal" web app traffic.

    Cheers

    Daniel
