There are two ways we do this.

• We have VPN access so anything can only be accessed if one is logged into VPN. We can just remove VPN access for the user and everything will be out of reach.
• For services like database, FTP we use multiple users and application alos has it's own user so application does not need to be changed if any other access changes. Application user will not used by any person, It is only used by application.

There are multiples configurations available for blocking specific IP or allowing specific IP/range for services. Plesk Firewall(Only Available on Windows) can be used to allow/deny any IP/Range from accessing a specific port. So in this case if we want to allow access to our database(MySQL, MSSQL), FTP and Plesk from a specific IP then we can add the following rules.

Allow IP 1.2.3.4 on

Service	Port
Plesk	8443
MySQL	3306
FTP	22
