List of limitations

KUMA has some limitations that are not critical for the operation of the application:

• When creating a correlation rule on Selectors tab, if you specify the return value of the last_index_of or index_of functions in local variables, you need to add 0 to this value. Otherwise, the comparison result is always equal to false. Example:

  index_of($dst_user_name_subs_to_lower, $dcs4_to_lower) + 0
