Each method has its own advantages and disadvantages in terms of complexity of implementation, versatility, and the level of security that it provides. More specifically: the more secure and versatile a method is – the more complicated it is to implement.

On June 3rd, the InfosecMatter blog published a post titled “Top #10 Vulnerabilities: Internal Infrastructure Pentest“. This blog post detailed the top most common vulnerabilities in Windows servers and networks found during more than 60 internal infrastructure penetration tests around the world. After reading this article, I was prompted to actively look for similar resources on SQL Server penetration testing, and I got some interesting findings. Check out my blog post at the Madeira Data Solutions website for the details.

So, today I’ll use this opportunity to talk about one such interesting incident.
