HTTP Protocol Compliance Failed

Hi there,


we are experiencing Authenticated Incident - HTTP protocol compliance failed for one of our client.


we are trying understand the reason for this alert has been triggered by ASM F5 ?


We are also trying to know the violation which is triggering this alert, as this seems to be an false positive to us.


Thanks Sathya AKA Sunny Junior Infosec security analyst

    ASM Generates Support ID in case of any request logged in it. Can you share details against that particular request from support ir.


  • Hi,

    the reason of blocking you can filnd in asm logs. Logs store is /var/log/asm.

    For ex. part of log message:

    Request blocked, violations: HTTP protocol compliance failed.

    HTTP protocol compliance sub violations: Null in request.

    Settings for HTTP protocol compliance are in Security  ››  Application Security : Blocking : Settings -> section RFC Violation > HTTP protocol compliance failed.
