This section also explains how to mitigate these attacks by implementing the correct control in Cisco IOS.ДЇollowing are the main types of Layer 2 attacks: This section covers several types of Layer 2 attacks. One of the best tools used for testing Layer 2 security is Yersinia that is freely available from and is part of the BackTrack 4 security distribution.

The availability of dedicated Layer 2 attack tools makes it necessary to defend against possible attack by implementing the features that Cisco offers within IOS Software. Layer 2 attacks are often overlooked when designing a network security solution it is quite normal to find Layer 2 networks with no protection whatsoever. We know that switching operates at Layer 2 therefore, most of these attacks need to be mitigated in the switches you deploy in your network. Layer 2 attacks occur, as you would expect, at Layer 2 of the OSI model. A lot of attention is paid to securing the higher layers of the OSI reference model with network-level devices such as firewalls, intrusion protection systems (IPS), and applications such as antivirus and host-based intrusion protection (HIPS).
