What is the difference between Mac flooding and MAC spoofing?Īll MAC flooding tools force a switch to “fail open” to later perform selective MAC spoofing attacks. Without this you are totally vulnerable to this form of attack. An attacker can flood a network with ARP requests, confusing equipment, slowing networks, slowing packets enough for intrusion, etc. Smart ARP – ARP is how your network equipment (router, switches, etc) knows where to send packets. Anyhow, once there is ARP cheat in network, the data between computers and router will be sent to wrong MAC Address and the connection can’t establish normally. In network the Address Resolution Protocol (ARP) is the standard protocol for finding a host´s MAC Address when only its IP Address is known. With ARP Spoofing is you start yelling out “Hey! What is ARP cheating? Arp spoofing is used to perform a MITM attack as you mentioned. But mac spoofing is legal and can be done without any particular software. What is the difference between ARP poisoning and MAC spoofing?Īrp spoofing is more complicated and it includes poisoning the arp cache of target computer. This mapping is a critical function in the Internet protocol suite. The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This causes data to get sent to the wrong MAC address when responding, losing the message in the pipes.

In Layer 2 of the OSI model theres a protocol used called the Address Resolution Protocol (ARP), which maps a MAC Address to an IP Address, this is used to physically route information around a local network. All ARP request messages must be processed by all nodes on the local network. What are the two problems that can be caused by a large number of ARP request and reply messages?Ī large number of ARP request and reply messages may slow down the switching process, leading the switch to make many changes in its MAC table. If an entry is incorrect, clear the ARP cache to resolve the problem. Compare the output with the correct IPv4 address and MAC address combinations. View the ARP cache on the computer that is experiencing the problem.

On large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays.

Manually configuring static ARP associations could facilitate ARP poisoning or MAC address spoofing.

At this point attacker starts sniffing the connection and try to find communication between hosts and servers. When this happens switch starts work as hub and send the packets to all port. Attacker flood this switch with mac addresses until CAM table overflows. there are group of users on vlan 20 and vlan 10. Credits : This video is simple demo of MAC flood attack to Cisco layer 3 switch. The advantage of this method is that data is bridged exclusively to the network segment containing the computer that the data is specifically destined for. This allows the switch to direct data out of the physical port where the recipient is located, as opposed to indiscriminately broadcasting the data out of all ports as a hub does. Switches maintain a CAM Table that maps individual MAC addresses on the network to the physical ports on the switch. Description: In computer networking, MAC flooding is a technique employed to compromise the security of network switches.
