Top 5 Security Methods to Secure Your Plesk Server
Data security is of utmost importance to businesses of all sizes. Enterprises should implement basic best practices in order to secure confidential website data from harmful assaults. A set of server security features that are included with the Plesk server offer a high level of server protection. Even though Plesk includes robust server security, Plesk security features can do more to further increase the security of your server.
In order to enable a high level of security for the server, this post highlights some of the best methods to protect your Plesk server.
Top Methods to Protect Your Plesk Server
1. Updated Plesk
Before taking any further action, you should always make sure your Plesk settings are up to date. The Plesk updates automatically install any components you might need to greatly increase server security. The greatest approach to securing a Plesk server is to always keep it updated. Therefore, use the method below to verify if you have an updated version:
Choose “automatically install Plesk updates” under settings.
You should verify the installation of Plesk ModSecurity, Fail2Ban, and Firewalls as a part of the Plesk updates.
2. Security procedure
Plesk’s security settings may permit secure FTP connections to the server.
Additionally, you can switch the password to a strong password policy.
To modify the minimum required password,
- Navigate to settings
- Go to Security
- Find the Password strength by scrolling down and selecting your preferred password strength policy. Thereafter, Input Ok.
FTP can stop assaults using FTP if it only allows authorized connections to the server. Secure the server with a strong password to prevent attacks on the primary login, which raises the level of security. Therefore, by using this technique, we are preventing brute-force attacks on the server.
3. The attack using force and Fail2Ban
Your Plesk server file logs are automatically monitored and protected from brute-force assaults with the aid of Fail2Ban. The prohibited login is regarded as suspicious by it, if enough of these logins are made, the Fail2Ban either notifies the user or temporarily blocks their IP address from accessing the server.
The following is how Fail2Ban can be configured:
- Make a filter using one or more regular expressions that can be used to look for suspicious log file behavior.
- Jail is a set of possible individual scenarios. In the event of an assault, this might make it possible to execute the necessary actions using the specified data.
- Indicate the IP address that was assigned. Your server will be protected from assaults if you restrict access to just approved IP addresses.
In addition to these, you may try turning on or off a jail you’ve established. On the other side, if you felt the need to, you may try unbanning the blocked IP address. In general, Plesk has a ton of predefined prison setups and filters. Consequently, setting one up for yourself is simple. Get in touch with your server and web hosting support provider if you require professional server engineer help for Plesk server administration services.
4. ModSecurity’s Web Application Firewall configuration
Web Application Firewall Configuration aids in identifying and preventing attacks on your web applications. A preset set of rules in the web application firewall determine which requests should be handled. In other words, if a user queries a website, the firewall is triggered and the HTTP request only obtains content from the site if the verification is successful.
You may activate ModSecurity using Plesk, and you can even add your own custom settings for the modes and set of rules. Do the following to install the ModSecurity part:
- To remove or add parts, navigate to Settings
- Go to “Updates & Upgrades”
- Under that choose “Add/Remove Components”
- And select “Web Hosting Groups”.
Now, you can either use a predefined set of ModSecurity rules or make your own.
5. Plesk Firewall configurations
The firewall configurations manage the network connections entering your server and protect the security of Plesk. The steps are as follows:
- The first step is to select “Tools and Settings” and then “Firewall management”.
- A status box for authorizing the firewall module will now be visible. Simply turn it on.
- You have reached your destination if you see a green box with the text indicating that the firewall management has been activated successfully.
If you want to modify the Firewall rules then,
- Choose “Modify Plesk Firewall Rules” from settings.
- Afterward, select the SSH server
- Choose the option to allow traffic from a few sources while blocking others under properties.
- Include the IP address you wish to provide access.
- Lastly, input OK.
