This is a buffer overflow attack and the best protection against a buffer overflow attack is input validation.
Notice that this is an HTTP log entry and it has several sections. - this is the originating IP address (where the HTTP query came from)
[9/June/2016:00:15:40 +1200] - This is the date and time stamp.

However, the Get command is a structured query and not random.
. It is not an attack.
