Fast forward about to about three years ago, when I started to get into dedicated servers quite heavily. This is when I began to host gaming servers for friends, and boy, let me tell you, it was a learning experience. Before I continue, let me say that I am by no means an expert on this subject, but I like to think I have more knowledge than the Average Joe when it comes to dedicated servers. So please, take this article with a grain of salt, and by all means, give me some feedback on what you would do, and why. Anyhow, back on topic! ModSecurity: ModSec for short!

RDP stands for Remote Desktop Protocol, and is a technology that allows users to log into remote work stations across the internet. RDP may be used by both, telecommuters and tech support personnel that are troubleshooting an issue via a secure name and password.

Emotet is a sophisticated Trojan that commonly functions as a downloader or dropper of other malware.
