Joshua Copeland's cyber security moniker is "The Unpopular Opinion Guy", while most of us in security roles have been that person with an unpopular opinion at least a time or two, Copeland turned it into both a book and a bit of a movement through numerous posts on Linkedin about many of the challenges in our industry.
That said, this is not a mud slinging episode, Joshua had numerous, pragmatic examples of both the problem space and ways to address them. There are a lot of misconceptions about cyber security but there are also a wide array of real world impacts in our daily lives making this a very difficult area to master. Mr. Copeland has some of the unlock codes, making for another compelling episode.
