Re: ARP: ARP Spoofing Detected



 Sensor remembers ARP and Reverse ARP (RARP) requests (for a specific time period), and matches an ARP reply with an ARP request message. Due to this ability, it can detect the following attacks:
  • ARP Spoofing Detected: If an ARP reply message is seen without a prior ARP request.
  • ARP Spoofing, Duplicate MAC: Detection of multiple ARP reply packets, with different sender MAC addresses for the same IP address that is being resolved.
  • MAC Address Cloned: Multiple and different replies to an RARP request; the exact opposite of 2.
The Sensor can also detect anomalous ARP reply packets, with a broadcast destination MAC address, and request or reply packets, with a broadcast sender addresses.
