Final answer:
The common error condition during an ARP spoofing attack is the misassociation of IP addresses with incorrect MAC addresses, leading to a man-in-the-middle situation where data can be intercepted by the attacker.
Step-by-step explanation:
The error condition commonly seen during an ARP spoofing attack is the misassociation of the IP addresses to the wrong MAC addresses on a local area network (LAN).
This occurs when an attacker sends forged ARP (Address Resolution Protocol) messages onto the network. The ARP protocol is used for mapping IP network addresses to the physical MAC addresses of hosts connected to the network. In an ARP spoofing attack, the attacker sends fake ARP messages that associate their own MAC address with the IP address of another host, such as the default gateway or another computer on the LAN.
As a result, devices on the network send data to the attacker instead of the actual destination. This can lead to the attacker intercepting, modifying, or blocking data, which is known as a 'man-in-the-middle' attack. The primary security goal compromised in this scenario is data confidentiality and integrity.
