F5 BOT DEFENSE AWAF blocked some legitimate browsers

Hi Community,

 

May I ask if F5's AWAF Bot Defense is still not being refined cause it causes some request from browsers to log it as a Malicious Bot, and therefore, this causes to block the request? May I ask what is the best practice for implementing the BOT defense feature?

Thank you and have a nice day!

 

 

Regards,

    For your second question about a Best Practices for implementing the Bot Defense.

      Oh Thank you for these links, sir! 

      I read it and saw the part that it requires the F5 device to have DNS resolver configured. Is this a necessity for the whole function to work properly or just some other features of BOT defense cause it is the practice of our client to disallow any dns lookups from their DMZ server environment? Maybe that is why I got false positives in bot defense?
