How to trick the DHCP server to not provide IP address to devices, what will completely block new connections? It could be done by DoS attack called “DHCP starvation attack“. We will show you how to do it and how to protect your network.

I studied at the Slovak Technical University in Bratislava at the Faculty of Electrical Engineering and Information Technology with specialisation in Telecommunications, where I completed my engineering studies. During this time I completed the Cisco CCNP Routing & Switching certification and later came with CCDA, CCNA Security and Fortinet Network Security Professional NSE4 certification.
Is it possible for someone to capture your entire network or internet communication? Yes it is! With ARP spoofing it is very easy. Only 4 CLI commands are needed.
We will show it on a simple example. We will capture communication between router R1 and switch SW1. Our attacking host is called KALI.
Let’s say we want to capture the admin username and password that logs in from SW1 to R1 using TELNET, which is unencrypted.
