Create Lookup Data Set to block Parameter values

  • 1.  Create Lookup Data Set to block Parameter values

    Posted 05-20-2025 00:36

    Hi all,

    I'm trying to block multiple Parameter values using a Lookup Data Set, but it seems like it only works with Parameter names.

    Example:

    I create a Lookup Data Set "test" with default column (key) and add usernames that i want to block like: test, test1, test2

    Policies i setup: Field = Parameters; Operation: At least one; Lookup Data Set = test

    But it doesn't block requests with UserName=test at all.

    Full payload: UserName=test&Password=hihihihehehe&AuthMethod=FormsAuthentication

    If I no longer use parameter values and switch to parameter names instead, meaning the Lookup Data Set will be UserName, Password instead param value test, test1, test2, it will be blocked but block all request with param name=UserName or Password

    Therefore, please help me create a policy that blocks parameter values in the payload using a Lookup Data Set.

    Thank you.
