Switches are fantastic devices, allowing you to create VLANs, trunks, as well as offer fast and somewhat private communication. In this course, Securing the Switch, you will explore the basic nature of switch operation, as well as the advent of trunk links, VLAN tags, and some backwards compatibility features. First, you will start off by learning about frame double-tagging. Next, you will move onto the native VLAN security issues and DTP. Finally, you will wrap up the course with a demonstration of creating a secure base configuration for a switch. By the end of this course, you will know how to put a secure base configuration on a switch, mitigating many layer 2 attacks against Ethernet.
Course Overview Hi, everyone. My name is Ross ________ us 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 either net was being developed in seventies and eighties. However, by the mid to late 19 nineties, 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 and switch design, especially, and shrunk link operation. In this course, we're gonna cover the native villain and the security issues it creates. Mac address flooding of a switch and switch port 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 two attacks against either net before beginning the course. You should be familiar with switching the lands and V land trunk ng. From here, you should feel comfortable diving into the rest of the CCN A series. I hope you'll join me on this journey to learn.
