ARP Cache Poisoning Attack
ARP cache poisoning attack or ARP spoofing is a type of cyber attack where an attacker sends fake Address Resolution Protocol (ARP) messages over a local network. ARP is a protocol that maps the Internet Protocol (IP) address to a physical or MAC address on a local network.
In an ARP spoofing attack, an attacker sends fake ARP messages that contain the attacker’s MAC address instead of the actual device’s MAC address. As a result, any network communication sent from other devices will be sent to the attacker’s MAC address instead of the intended device’s MAC address. The attacker can intercept, modify, or steal sensitive information sent over the network.
ARP spoofing attacks are commonly used in man-in-the-middle attacks, where the attacker intercepts network communication between two devices to eavesdrop, steal information, or inject malicious code.
To prevent ARP spoofing attacks, network administrators can use various techniques such as static ARP tables, dynamic ARP inspection, or port security. Users can also protect themselves by avoiding unsecured public Wi-Fi networks and staying up to date with security patches and updates.
In summary, ARP cache poisoning attack is a type of cyber attack that involves sending fake ARP messages to redirect network communication to the attacker. It is important to be aware of this type of attack and take necessary precautions to prevent it.
