Plesk Security: Best Practices To Secure Plesk Server
You should always ensure that you are having updated Plesk settings before moving further with other steps. The Plesk updations automatically install the components which you may require to make your server super secure. Keeping an updated Plesk is the topmost among the best practices to secure Plesk server. Hence, to check if you have an updated version, follow the steps below:
Go to Settings > select automatically install Plesk updates
With the Plesk updations, you should be checking the installation of components such as Fail2Ban, ModSecurity, and Plesk Firewalls.
The security policy of Plesk can allow secure FTP connections to the server. Also, you can change the password strength policy to a strong password. To change the password minimum requirement,
Go to Settings > Select Security > Scroll down and find Password Strength> choose your desired password strength policy > Click OK
If FTP gives access to authorized connections to the server, it can prevent attacks via FTP. Securing the server with a strong password can avoid attacks on the main login which enhances Plesk security to a level. Hence with this method, we are protecting the server from Brute force attacks.
Brute Force Attack And Fail2Ban
The Fail2Ban helps to monitor and protect your Plesk server log files automatically from brute force attacks. It considers the unauthorized login as suspicious. If such login activities are counted to a minimum number, the Fail2Ban either sends a notification or bans the IP address from accessing the server to a particular time period.
Configuration of Fail2Ban can be done as follows:
- Create a filter that could have one or more regular expressions which can be used to search the suspicious log file activity.
- A set of individual scenarios, jail can be created. this could enable to take necessary actions using the predefined data if an attack occurs.
- Specify the delegated IP address. By giving access to only authorized IP addresses to your server, your server is safe from attacks.
Other than these, you can try activating or deactivating a jail you have created. On the other hand, you may also try unbanning the banned IP address if you required it. Generally, the Plesk comes with a lot of predefined filters and jail configurations. Hence, it is easy to configure one for yourself.
