Description: 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.
What is jnxJsScreenMonIpSweep?
This read-only counter tallies address-sweep attempts detected in this zone, triggered when one source IP sends ICMP packets, typically echo requests, to enough different hosts within the configured interval. An admin watching this counter climb knows someone is scanning the zone's address range to discover live hosts.
