VPSs cater to you and your needs while giving you the freedom of running your own hardware. VPSs are powered by an operating system like Linux or Windows. This allows the customer to install the OS of their choice on the server.\r\n\r\nIf you are planning to purchase VPS hosting<\/strong><\/a> Or you already have one, securing your VPS is a vital part because you are hosting your website on it. When you order your VPS, a distribution or operating system is pre-installed, but no security protocol is implemented natively. It is therefore up to you to secure your VPS.\r\n\r\nThis guide offers some general tips for securing your server.\r\n

1. Use only SSH to log into your server<\/strong><\/h3>\r\nYou can log in to a remote server by using the SSH (secure shell) cryptographic network protocol for operating network services. The SSH protocol can offer you the highest level of encryption and you\u2019ll be able to direct insecure traffic (coming to your server) through a secure connection.\r\n\r\nYou can secure SSH logins by\r\n\r\nDisable root logins<\/em>\r\n\r\nDisabling logins from the \u201croot\u201d username adds another layer of security, as it stops hackers from simply guessing your user credentials. Instead of logging in as the root user, you\u2019ll need to create another username and use the \u201csudo\u201d command to execute root-level commands.\r\n\r\nopen up \/etc\/ssh\/sshd_config<\/code> in nano or vi editors and find the \u201cPermitRootLogin\u201d parameter.\r\n\r\nBy default, this will say \u201cyes\u201d.\r\n\r\nChange it to \u201cno\u201d and save the changes.\r\n\r\nChange the SSH port<\/em>:\r\n\r\nDefault SSH port is 22, changing the SSH port number can prevent malicious scripts from directly connecting to the default port (22).\r\n\r\nopen up \/etc\/ssh\/sshd_config<\/code> and to change the appropriate setting.\r\n\r\nMake sure to check whether the chosen new port number is being used by any other services \u2013 you don\u2019t want to create a clash!\r\n

2. Use Strong Password<\/strong><\/h3>\r\nWeak passwords always have been \u2013 and always will be \u2013 one of the largest threats to security. Don\u2019t allow user accounts to have empty password fields. You must have a strong and long password.\r\n

3. Always install the latest security updates<\/strong><\/h3>\r\nIt isn\u2019t difficult to update your server\u2019s software.\r\n\r\nYou can simply use the rpm\/yum package manager (CentOS\/RHEL) or apt-get (Ubuntu\/ Debian) to upgrade to newer versions of installed software, modules, and components on the Linux platform.\r\n\r\nWe recommend checking out for such at least once a week.\r\n\r\nBoth cPanel and Plesk provide utilities that allow you to update software within their web interface, or if you want you can easily do it via SSH at any time.\r\n

4. Using a firewall is essential<\/strong><\/h3>\r\nThe first thing you should do when securing your Linux VPS is to activate and set up a firewall such as\r\n
