Securing the Switch for Cisco CCNA 200-125/100-105

Course Overview
Hi, everyone! My name is Ross Bagurdes and welcome to my course, Securing the Switch. I am a network engineer with 20 years experience building and managing Enterprise networks and teaching people about them. Switches may or may not have been part of the Ethernet vision when the Ethernet was being developed in the 70s and 80s. However, by the mid to late 1990s, switching became an important piece of data networking and has not stopped growing since. Because of this rapid implementation and growth of Ethernet and switching, there was not always an eye focused on security flaws in switch design, especially in trunk link operation. In this course we're going to cover the native VLAN and the security issues it creates, MAC address flooding of a switch, and switchport Port security which is a mechanism we can use to prevent some security issues. By the end of this course you'll know how to put a secure base configuration on an Ethernet switch, mitigating many layer-2 attacks against Ethernet. Before beginning the course you should be familiar with switching, VLANs, and VLAN trunking. From here you should feel comfortable diving into the rest of the CCNA series. I hope you'll join me on this journey to learn switch security with the Security the Switch course at Pluralsight.
