2. Deactivate the Root Account
Root login is widely used by hackers to breach security protocols. You should disable this login option as soon as you can. You can instead use the sudo access, which is more secure and hard to breach. Create unique individual accounts for every user on your Linux VPS with limited permissions, just enough for them to do their job. The rest of the permissions should not be accessible to them. This way, mistakes committed involuntarily by the users do not compromise your entire network. Disable all the unused accounts in your VPS hosting to minimize unnecessary risks. It is also worth mentioning the importance of installing security updates regularly.

Find a balance between the need to allow necessary permissions for proper apps function and maintaining security to your Linux VPS. As a rule, allow as few permissions as is necessary. The fewer the permissions, the more secure your Linux VPS is.

Deny access to the other ports to optimize usage and guarantee better security. You could consider using IPTables, which is a popular modern day firewall for Linux VPS.
