#103: Kali Linux: Hacking Networks Part 2

It's so easy to hack badly configured networks using Kali Linux! See how easy it is to take out networks using Kali Linux and protocols like Dynamic Trunking Protocol (DTP) and VLAN Trunking Protocol (VTP); and also capture network traffic using Wireshark. Make sure you have configured your networks securely! Otherwise, look at how simple it is to hack networks using Kali Linux running on a Windows 10 computer. Applications like Yersinia make hacking with Kali Linux super easy! It's important that you as a network professional know how to protect networks from hackers. Even the new Cisco CCNA 200-301 exam covers some of these hacking topics. Don't just learn the theory of hacking, learn how to hack practically. In this Ethical Hacking with Kali Linux playlist, I'm going to show you step by step how to hack and protect networks. This is white-hat hacking, not black-hat - in other words this is about teaching you Ethical hacking to help you better secure your networks! In a previous video I showed you how to get started with Yersinia and hack CDP and Spanning Tree Protocol (STP). In this video I show you how to leverage DTP and VTP to hack networks with kali linux. Make sure you learn how network protocols work and understand their weaknesses. Just because a Cisco switch or router supports a protocol, doesn't mean you should enable it and use it. In many cases you need to either optimize the network protocol or disable it. Otherwise, hackers using Kali Linux will be able to hack your network and break things.
