That approach is a good defense in depth technique. Network security by itself doesn't work but entirely neglecting it as some misguided articles I read recently makes me wonder if security is actually moving backwards when it comes to fundamentals and principles. Granted those supporters are frequently cloud vendors, that dont offer mature enterprise integration. But when smaller shops follow those as best practices I'm getting worried.
