Simple and straightforward article that exposes one of many usual misbehaviors of so called sysadmins these days: they think they know their tools, but haven't even completely read the manual for the programs they rely on production environments. Systems administration is something to be taken seriously; recently a friend of mine, that knows nothing about network perimeter security and didn't enforced adequate credentials on production environments, got a RANSOMWARE on a machine with a critical for business instance of a CRM database, chiefs on the organization refused to pay for the bitcoins asked, and probably my friend will be fired for incompetence; the infrastructure department personnel doesn't even have backups of such server, it's clear the information is lost forever.
