    Hi karthicksankark , 

    >>> your Q : The Enforcement Readiness Period is 7 days. After 7 days ony I started looking into the learning suggestions will that be a cause. if so how can i see the current suggestions. ? 

    Answer : No , you should see suggestions, and let me explain. 

    First what is the Learning mode that you're using in each Entity ( Entity means >> File types , parameters , URLs ) Learn mode contains ( Never ( Wildcard only ) , selective , Always , and Compact ). 

    If you want to learn everything in your AWAF , you need to modify it to Always , to see suggestion from each request. and make sure you enable ( Learn Check box ) for each entity.

    Also Make sure to enable learn check box in ( Evasion Technique , http compliance and attack signatures ) 

    Till here I answered your Questions of how to get suggestions. 

    For more info about learning modes , Refer to this Article :

    Specially this part : 


    Also Listen to this Video :

    After that let me know , if you need anything. 

    I hope that helps you , GoodLuck 🙂

I personally dont like the automatic learning modes due to the fact that if a hacker or someone meaning to do harm to your system all they need to do if generate enough traffic from different IP addressses and it will automatically be added to your policy.  have you checked if alarm and learn are both checked since I have seen learning suggestions not pop when the alarm is not set ? also if you have told ASM in the past to forget about the event it will not show back up.

Hi Thanks for the heads up on the risk in the automatic learning mode. Will opt for manual learning mode. 

I double checked the entities that have both learn and alarm enabled. 

In the logging I have used log illegal requests profile. 

 

Thanks,
