Top 5 Plesk Security Practices to Secure Your Plesk Server

Data security is of utmost importance to organizations of all sizes. Businesses should implement top practices to secure confidential website data from harmful assaults. A Plesk server comes with a selection of security and hardening features that provide a higher level of server defense. Plesk includes robust server security, its security features can do more to further increase the security of your server.

As a top-quality provider of server management services, we view server security as a crucial component of server administration. To enable a high level of security for the server, we would like to discuss some best practices for protecting your Plesk server in this post.

Top Practices to Safeguard Your Plesk Server

1. Updated Plesk

Make sure your Plesk configurations are up to date before taking any action. The Plesk updates automatically establish any components you might need to greatly increase the server’s security. The greatest approach to securing a Plesk server is to always keep it updated. Use the below methods to understand if you have an updated version:

Choose “Automatically Install Plesk Updates” under settings.

You should verify the installation of Plesk Firewalls, Fail2Ban, and ModSecurity as a part of the security updates.

2. Security Procedure

Plesk’s security settings may permit safe FTP connections to the server. You can switch the password settings with a strong password.

To modify the required minimum password:

Navigate to “Security” under settings, find “Password Strength” under that tab, and select your preferred password policy strength. Now, click on OK.

FTP can stop assaults if it only allows permitted connections to the server. Secure the server with a secure password to prevent attacks on the primary login, which raises the level of Plesk security. By using this technique, we are preventing brute-force attacks on the server.

3. Attack Using Force and Fail2Ban

Plesk server log files are monitored and protected from brute force assaults with the aid of the Fail2Ban. Any unsanctioned login is regarded as suspicious by it. If any of these login attempts are made, the Fail2Ban either notifies the user or temporarily blocks their IP address from obtaining access to the server.

How to configure Fail2Ban

• Create a filter employing one or more regular expressions that can be used to look for unusual log file behavior.
• Jail is a set of possible individual scenarios. In the event of an assault, this might make it possible to execute crucial actions using the specified data.
• List the IP address that was given. You can prevent attacks on your server by limiting access to only authorized IP addresses.

In addition to these, you may try turning on or off a jail you have established. On the other side, if you felt the need to, you can try to unban the blocked IP address. In general, Plesk has a ton of predefined prison setups and filters.

4. ModSecurity’s Web Application Firewall Configuration

ModSecurity aids in identifying and preventing assaults on your web applications. A set of rules and regulations in the web application firewall determines which requests should be handled. In other words, if a user raises a query, the firewall is triggered and the HTTP request only obtains content from the site if the check is successful.

You can now add your customized settings for the set of rules and activate ModSecurity using Plesk.

This is what you can do to install the ModSecurity component:

To remove or add any component, you have to go to the “Updates and Upgrades” settings. Under that go to “Add/Remove Components” and find the Web Hosting Groups.

Now you can either use preset ModSecurity rules or make your own.

5. Configuring the Firewall

Your Plesk Firewall keeps an eye on and protects the network connections coming into your server. The steps to configure are as follows:

• The first step is to select “Tools and Settings” and “Firewall Management”. Choose “Firewall Rules Management” and turn it on.
• Now, it will show a preview of the status box authorizing the Firewall module. Simply turn it on.
• If a successful green box appears and the Firewall rules management is active, you have arrived at your destination.

To change firewall settings,

• You can change Plesk Firewall rules with the help of Tools and Settings.
• Now, select SSH server.
• Choose the property option that lets you let traffic from some sources through while blocking it from others.
• Include the IP address you wish to provide access.
• Click on OK.
