ABSTRACT Open System for Interconnection model was developed to allow different types of layers to work independently to send the information from source system to destination system in effective manner. The security mechanism is implemented from layer 3 to layer 7 in the OSI model architecture and the current firewall technology has a very limited scope on protecting the laye2 devices. Once the layer 2 devices are compromised then all remaining layer will be compromised easily. In order to protect the Laye 2 devices against the possible attacks a network engineer should have an in-depth knowledge on possible attacks and mitigation techniques. The objective of this paper is to perform the different types of possible attacks that can be happen in the layer 2 networks and mitigation techniques such as DHCP snooping attack, Telent Attacks, Mac-Flooding, Port Security, VLAN attack and Denial-of-Service (DoS) attacksare discussed in this paper with the help of Cisco Packet Tracer Simulator and GNS3 simulator.
