Security of a server is paramount in the digital realm. Users of Plesk, a popular web hosting control panel, have a wide array of tools at their disposal to ensure the protection of their servers. In this article, we will explore how to properly configure server security in Plesk and keep data safe.

Basic Configuration

The first step is to ensure basic security configuration. Plesk offers a security advisor that guides users through fundamental settings such as software updates, firewall setup, and security policy configuration. It is crucial to regularly update Plesk and all third-party software to patch any known security vulnerabilities.

Firewall Setup

Plesk includes a Firewall tool that allows users to easily configure rules for inbound and outbound connections. It is strongly recommended to only enable necessary ports and services. Additionally, restricting access to the server only from trusted IP addresses is advisable.

SSL/TLS Security

Securing connections using SSL/TLS certificates is essential for protecting transmitted data. Plesk enables easy installation and management of SSL/TLS certificates, including automated certificate issuance using Let's Encrypt. Configuring strong encryption algorithms and regularly renewing certificates are key to securing communication.

Protection Against Attacks

To protect the server against common attacks such as brute force, DDoS, and more, Plesk offers a variety of tools. ModSecurity, a web application firewall (WAF), can help protect web applications by filtering out malicious traffic. Activating fail2ban, a tool that monitors logs and automatically blocks IP addresses engaging in suspicious activities, is another effective step.

Backup and Monitoring

Regular backups are a fundamental pillar of a security strategy. Plesk allows for configuring automatic backups to local storage or Cloud services. Additionally, it is important to monitor the server using Plesk tools or external services to quickly identify and respond to security incidents.

Securing a server is an ongoing process that requires continuous attention and updates. By leveraging the tools and recommendations provided in Plesk, you can significantly enhance the security of your server. It is also important to stay aware of new threats and continuously educate yourself in the field of cybersecurity.
