System Hardening
System hardening is the process of securing a computer system by reducing its attack surface and vulnerabilities through configuration changes, software updates, and security best practices. It involves applying security measures to operating systems, applications, and network components to protect against unauthorized access, malware, and other threats. The goal is to make systems more resilient to attacks while maintaining functionality.
Developers should learn system hardening to build and maintain secure applications and infrastructure, especially in production environments or when handling sensitive data. It is critical for roles in DevOps, cybersecurity, and cloud computing, where systems must comply with security standards like ISO 27001 or GDPR. Use cases include securing servers, containers, and IoT devices to prevent breaches and ensure data integrity.
