Once you get your hands on a VPS, one of the very first thing you need to do is to secure your VPS from threats. No matter how obscure your server is, there will always be attempts to break into it in order to make use of its precious resources for malicious activities or for the attacker’s own gain. It only takes a few days for one to begin looking for holes to exploit your server. If you are a long time owner and have successfully built a website or web app on your VPS, then you cannot afford losing all of your work when someone broke into your server, deleted your files and/or injected malicious codes and files to your server.
It is, therefore, very important to secure your VPS to make sure that nobody could gain access to it. Here are some tips to secure your VPS.
Use Strong Password
It’s a no-brainer. In this day and age where our lives largely depend on the internet for a lot of things, having a strong password is a must. You certainly use social networks, play online games or work online and these requires you to have an account most of the time which, of course, also requires you to have a password. Believe it or not, one of the primary reason why people get hacked is because of using weak passwords. I can understand password strength ignorance in the year 2000s, the time when only few people have access to the internet, but in this day?
Oh, right. You thought that using a secure password is a mess because it’s hard to remember. Actually, using a combination of memorable words, numbers and special characters makes your password exponentially stronger, you don’t even have to create a cryptic code for your password. Essentially, a password like “i!@#9ase!@#&&*_!” is as strong as “Gilly_Hopkins!!@15”, which is far easier to remember. So don’t be afraid to create strong passwords, heck there are even password managers like LastPass to help you with that.
Not all ports are essential. You probably have a firewall on your computer. Basically, it’s acts as a wall and gateway that filters traffic to and from your web server. They decide whether to allow a certain traffic from either going in or going out. They are your security guards.
Of course, they don’t decide by their own. They do this by analyzing a traffic and then looking at a specific set of rules define by the user. Configuring a firewall can be a bit tricky, but knowing which ports your server uses to communicate is one step towards the end of configuration.
Choose Reliable VPS Provider
There are lots of secure affordable VPS providers out there that adds layers of security to ensure that your website will be very hard to compromise. Of course, we can’t just let them do all of the dirty work. If you really want to prevent your VPS from the hands of hackers, you need to do your part too.
