After you buy VPS hosting for your online business, you go all the way through the course of action of setting it up and then configuring it. After that you teach yourself how to administer it by the book. Then you design your business website, host it on your virtual server and as soon as it starts generating a profit for all the investments you made, the website vanishes. After some investigation you find out that your website has been attacked and now controlled by a hacker. It will surely be a nightmare for you. So the significance of taking precautions to protect your VPS hosting account could hardly be overrated.
The below list contains some of the most basics steps a webmaster can take to keep his VPS hosting option safe.
All the passwords you have (user-account passwords, control panel passwords, root passwords etc…) should have more than 8 characters, and be different to each other. They must also include at least single special character (!@#$%^&*) and number (the more, the merrier) to reduce the risk of brute force attacks.
The VPS Hosting account must be always updated at the first instance you log in to SSH. After that you must set it up for automatic updates. This will make sure that the VPS server always stays updated.
In case if you stay with the default ports and settings in the VPS hosting account, malicious hackers that remember those ports and settings may be able to access it via them. Thus, to maximize the protection of the VPS, you must alter its default ports. You will also be able to prevent the majority of the automated bots that would simply brute force through the default server ports till they fall as a result of doing this.
