How to Identify Vulnerabilities ft. Nessus Vulnerability Scanner

Introduction:So one of my friends has done the CEH and the ECSA courses from EC-Council, and I am here learning everything from youtube without any certifications. I have my personal youtube channel with 18,000 subscribers and 10,000 views. So, he challenged me to complete some tasks and scan vulnerabilities to test my knowledge.Note: My only point here is to tell him that certifications or education is not 'everything'. While they are important and have their place in certain jobs, the experience is a huge factor as well. Actual knowledge is important i.e. practically doing things. I am not against any courses; however, I feel these courses are really costly compared to the knowledge they provide and that's the reason I have started a channel which provides that same knowledge, but for free (like Cybrary!).Here is the video in which I explain and demonstrate how to identify vulnerabilities with the Nessus vulnerability scanner.
