Apr 14, 2025 pm 06:03 PMSecurity is crucial to deploy Node.js applications on CentOS systems. This article provides an overview of best practices, covering application configuration and system-level security measures.
Node.js installation and configuration
- Recommended installation method: Use EPEL repository or NVM (Node Version Manager) to install Node.js to ensure the latest stable version and security patches.
- Verify installation: Use
node -v
andnpm -v
commands to verify that the installation is successful.
Application security configuration
- Avoid root permissions: Run Node.js applications as non-root users to reduce security risks.
- Update npm package: regularly update project dependencies, use tools such as
npm audit
or snyk to detect and fix security vulnerabilities. - Secure HTTP header: Configure secure HTTP headers, such as Content-Security-Policy and X-Content-Type-Options, to defend against common web attacks.
- Rate limiting: Use
express-rate-limit
and other middleware to limit the request rate to prevent DDoS attacks. - Input Verification: Strictly verify all user input to prevent attacks such as SQL injection and XSS.
- Enable HTTPS: Use SSL/TLS encryption to ensure all communications are secure.
System-level security measures
- Firewall configuration: Use firewalld or iptables to control network traffic, allowing only necessary ports and services to access.
- SELinux enable: Configure SELinux to restrict process permissions and enhance system security.
- Data backup: Back up important data regularly to prevent data loss or corruption.
- Log monitoring: Use
journalctl
and other tools to monitor system logs to promptly discover and handle abnormal behaviors.
Security practice platform
- It is recommended to use platforms such as VulnNodeApp to practice and test Node.js application security, and be familiar with common vulnerabilities.
Following the above steps can significantly improve the security of Node.js applications on CentOS systems. Remember that regular review and updates of security measures can be addressed in changing threats.
