Maintaining a clean & secure network

It has never been quicker or easier to deploy a server. Providers such as us allow customers to deploy a flavour of Linux (CentOS, Ubuntu, or Debian) in less than 60 seconds! This is fantastic, as it allows everyone from beginner server administrators to professionals to quickly utilize the many capabilities that Linux has to offer.

However, as with any operating system (i.e. Windows, Linux), it is vital that steps are taken to protect your server from attackers (this could be humans, or automated bots), as the consequences can be costly — consuming both time and money.

What can happen if a server isn’t properly secured?

Some of the most common consequences of a hacked/compromised server are that the server will be maliciously used for one or more of the following:

  • Spam: This one is pretty simple to grasp the concept of. Attackers may use your server to send out unsolicited mail. This could be anything from promoting their own websites, to financial investment emails where large sums of cash are offered.

  • Phishing: This is a practice in which a web page or email is maliciously crafted in order to trick readers into entering credit card details, login details, and so on into a bogus/fake form. Quite often, PayPal and Google are targetted.

  • Hacking: Your server may be used to attack other servers or internet devices. For example, it may be used to “bruteforce” login forms or protocols such as SSH, RDP, WordPress, etc. This can involve trying lots of username and password combinations.
