-====== Arpwatch ======+====== Network Monitoring with Arpwatch ======
  
 Arpwatch allows a system to track [[https://en.wikipedia.org/wiki/IP_address|IP]] address pairings.  It maps the [[https://en.wikipedia.org/wiki/MAC_address|MAC Addresses]] on a network by tracking [[https://en.wikipedia.org/wiki/Address_Resolution_Protocol|ARP]] requests to each device on the [[https://en.wikipedia.org/wiki/LAN|LAN]] and recording the response in a database.  All network cards are manufactured with a unique MAC address and this allows Arpwatch to identify each device.  The main purpose of mapping a network like this is so the system administrator can keep track of the devices on a network and identify when there are networking issues.  Arpwatch is commonly used to identify when an [[https://en.wikipedia.org/wiki/ARP_spoofing|ARP Man in the Middle attack]] is being conducted by notifying the system administrator when a duplicate MAC address is being used on the network.  Arpwatch is most commonly ran on routers, but it can also useful on a managed network switch. Arpwatch allows a system to track [[https://en.wikipedia.org/wiki/IP_address|IP]] address pairings.  It maps the [[https://en.wikipedia.org/wiki/MAC_address|MAC Addresses]] on a network by tracking [[https://en.wikipedia.org/wiki/Address_Resolution_Protocol|ARP]] requests to each device on the [[https://en.wikipedia.org/wiki/LAN|LAN]] and recording the response in a database.  All network cards are manufactured with a unique MAC address and this allows Arpwatch to identify each device.  The main purpose of mapping a network like this is so the system administrator can keep track of the devices on a network and identify when there are networking issues.  Arpwatch is commonly used to identify when an [[https://en.wikipedia.org/wiki/ARP_spoofing|ARP Man in the Middle attack]] is being conducted by notifying the system administrator when a duplicate MAC address is being used on the network.  Arpwatch is most commonly ran on routers, but it can also useful on a managed network switch.
