Securing your VPS is a bit of a process. Because you are operating your own virtual server, you’ll need to make a lot of changes in the software depending on your needs. For instance, managing the ports for shell access, passwording the root directory, managing user rights on the system, configuring firewalls, backing up the system, and installing anti-virus and malware software is usually your responsibility. Which is one of the reasons why you need a knowledgeable technician to maintain the VPS.
