What are the best practices for securing web servers on virtual machines?

Web servers are essential for hosting and delivering websites and web applications over the internet. However, they also pose significant security risks, especially when they run on virtual machines (VMs) that share resources and network access with other VMs. To protect your web servers from cyberattacks, you need to follow some best practices for securing web servers on virtual machines. In this article, you will learn about six key aspects of web server security on VMs and how to implement them effectively.

1 Choose a secure web server software

The first step to secure your web server on a VM is to choose a web server software that has a good reputation for security, performance, and reliability. Some of the most popular web server software options are Apache, Nginx, and IIS, but there are also others that may suit your specific needs. You should compare the features, updates, and support of different web server software and select the one that meets your security requirements and budget.

La configuration du protocole HTTPS pour chiffrer les communications entre le serveur et les clients. Cela permet de protéger les données sensibles et d’éviter le vol d’identité ou le piratage de session. Pour cela, il faut utiliser un certificat TLS/SSL valide et le stocker dans un coffre de clés sécurisé. La mise en place d’un système de sauvegarde et de restauration pour prévenir les pertes de données en cas de panne ou de corruption du serveur. Il faut choisir une fréquence et un mode de sauvegarde adaptés aux besoins et aux contraintes du serveur web. Il faut également tester régulièrement la capacité de restauration du serveur.

2 Configure your web server properly

The second step to secure your web server on a VM is to configure it properly according to the best practices for web server security. This includes setting up strong authentication and authorization mechanisms, encrypting the data in transit and at rest, limiting the access to the web server files and directories, disabling unnecessary services and modules, and applying the latest security patches and updates. You should also use secure protocols such as HTTPS, FTPS, or SFTP for data transfer and communication.

3 Harden your virtual machine

The third step to secure your web server on a VM is to harden your virtual machine against potential vulnerabilities and threats. This means that you should apply the same security measures that you would use for a physical server, such as installing a firewall, antivirus, and anti-malware software, creating strong passwords and changing them regularly, enforcing the principle of least privilege, and monitoring the system logs and activities. You should also isolate your web server VM from other VMs on the same host and network.

4 Implement backup and recovery strategies

The fourth step to secure your web server on a VM is to implement backup and recovery strategies that can help you restore your web server in case of a disaster or a breach. You should create regular backups of your web server data and configuration files and store them in a secure location, preferably off-site or in the cloud. You should also test your backups and recovery procedures periodically and update them as needed. You should also have a contingency plan in place for dealing with emergencies and incidents.

A dica é simples e direta: SEMPRE em qualquer hipótese tenha um backup recente de sua VM ou qualquer outro meio de recuperação que seja externo, qualquer infra pode sofrer ataques, desde a mais elaborada até a mais simples. Portanto tenha sempre uma ou mais maneiras de backup

5 Monitor and audit your web server

The fifth step to secure your web server on a VM is to monitor and audit your web server performance, traffic, and security. You should use tools and software that can help you track and analyze the web server metrics, logs, and events, and alert you of any anomalies or suspicious activities. You should also conduct regular security audits and assessments of your web server to identify and fix any weaknesses or gaps in your web server security.

6 Educate yourself and your team

The sixth and final step to secure your web server on a VM is to educate yourself and your team about the best practices for web server security on VMs. You should stay updated on the latest trends, threats, and solutions in web server security and learn from the experts and peers in the field. You should also train your team members and staff on how to use and maintain the web server securely and responsibly, and how to respond to security incidents and breaches.
