Thank you @PhoneBoy for your response.
At present I a have Enabled the FTP PATTERNS feature to detect mode with Packet Capture and loging enabled, but wanted to get a few thing clarified on the "Additional Settings" option, at present there is 2 options:
1. Use default Settings
2. Customize
Qusetion 1: What are the parameters selected in the "Use default Settings" option ?
Question 2: In customize we have only one option selected out of the total of 6 protections by default, since I have set it to detect mode with packet capture and logging enabled, would it not show the logs for the remaining 5 protections which are currently unchecked.
