One reason why cyber risks are far more serious today than in the past is the widespread and cheap access to services from registrars and hosting providers. From amateur bloggers to small business owners, anyone can register a domain and create a website for whatever purpose.
The problem is that not everyone has the right skills to properly configure servers — e.g., define hosts or set up address (A) or pointer (PTR) records, among other things.
Website owners are lucky if issues from nameserver misconfigurations only result in reduced website availability. There are other consequences, though, such as higher spamming scores and Secure Sockets Layer (SSL) authentication errors or vulnerabilities that could potentially lead to security compromises.
