Abstract. Security is at the forefront of most networks, and many companies implement a comprehensive security policy encompassing many of the OSI layers, from application layer all the way down to IP security. However, one area that is often left untouched is hardening Layer 2 and this can open the network to a variety of attacks and compromises. This document will have a focus on understanding and preventing the ARP Poisoning also known as the Man In The Middle MITM Layer 2 attack on the Cisco Catalyst 6. Cisco IOS Software. The Ettercap attack tool will be used to initiate Layer 2 attacks that you might encounter. Mitigation techniques to stop this attack are also covered. A Mac. Book Pro and a Lenovo T6. P laptops was used for these test and acted as the attacker in some cases and the victim in others. Both computers also ran VMware. Emerge List All Installed Packages Ubuntu' title='Emerge List All Installed Packages Ubuntu' />Note that the attacks performed in this white paper were done in a controlled lab environment. We do not recommend that you perform this attack on your enterprise network. Test Equipment. A Cisco Catalyst 6. E switch with a Supervisor 7. B running Cisco IOS Software 1. SXI1 in an Advanced Enterprise Feature Set and a WS X6. GE TX 1. 01. 001. Ethernet line card will be used. For the Attacker and Victim computers, an Apple Mac. Book Pro and a Lenovo T6. P were used. The Mac. Book Pro ran a native Mac OS X version 1. VMware Fusion 2. Ubuntu 9. Windows XP SP2 Virtual Machine. The Lenovo T6. 1P ran a Windows XP SP2 host OS and also had VMware with a Ubuntu 9. Virtual Machine. A Linksys USB3. It isnt hard to go from reading an article on your phone to reading it on your laptop. All you need to do is remember where you found it, right But searching for. M USB to 1. 01. Ethernet NIC was used on each machine. By using this particular NIC, no Bridging or NAT functions were needed in VMware. Basics What Will Be Installed Ansible by default manages machines over the SSH protocol. Once Ansible is installed, it will not add a database, and there will be. This guide describes how to work on Chromium OS. If you want to help develop Chromium OS and youre looking for detailed information about how to get started, youre. The Ubuntu 9. 0. 4 and Windows XP Virtual Machines recognize the USB to Ethernet NIC, so the Virtual Machines network connection was independent of the host Operating Systems. Wire. Shark was used as the packet analyzer in addition to debugs on the Cisco Catalyst 6. E switch to show how the attack was unleashed and the responseactions of the switch. ARP Address Resolution Protocol Poisoning MITM Attack. Minimal Package. The minimal version of Webmin contains only the core API and programs, and a few modules required for its basic operation.

A Man In The Middle MITM attack is achieved when an attacker poisons the ARP cache of two devices with the 4. MAC address of their Ethernet NIC Network Interface Card. Once the ARP cache has been successfully poisoned, each of the victim devices send all their packets to the attacker when communicating to the other device. This puts the attacker in the middle of the communications path between the two victim devices hence the name Man In The Middle MITM attack. It allows an attacker to easily monitor all communication between victim devices. The objective of this MITM attack is to take over a session. The intent is to intercept and view the information being passed between the two victim devices. Three 3 scenarios were used for the MITM attack. They were as follows Scenario. Description 1. Static IP Address on Attacker machine 2 DHCP from 8. Router DHCP Server on Attacker machine 3. DHCP from Cisco Catalyst 6. E DHCP Server on Attacker machine. These 3 scenarios were chosen because they were all valid configurations that one might see in a customers network although scenario 2 and 3 are more likely in an enterprise network. Scenario 1 Static IP Address on the Attacker Machine. In this scenario, the following hardwaresoftware was used Victim 1 Hardware Lenovo PC Software Windows XPIP Address 1. MAC Address 0. 0 1c 2.

The host operating systems on the attacker and the victim laptops were not using the Linksys USB3. M NIC, but they were being used exclusively by the Virtual Machines running inside VMware on each laptop. In other words, no Bridging or NAT was being done between the host Operating System via VMware to the Virtual Machines. Each Virtual Machine used a dedicated 1. Ethernet NIC USB to Ethernet. Figure 1 shows how everything was connected for the test. Screen shots snapshots were taken throughout each test covered in this white paper. These screen shots help prove that the attacks worked and display the success of the attack mitigation. Figure 1.       ARP Poisoning MITM AttackScenario 1. Steps for the MITM ARP Poisoning Attack 1.
