An address sweep occurs when one source IP address sends a
defined number of ICMP packets to different hosts within a
defined interval. The purpose of this attack is to send ICMP
packets, typically echo requests, to various hosts in the
hope that at least one replies, thus uncovering an address of
the target. The device internally log the number of ICMP packets
to different addresses from one remote source.
This attributes records the address sweep attemp attack packets.
