Infrastructure Security

Infrastructure Security is the practice of protecting the foundational components of IT systems—such as networks, servers, storage, and cloud environments—from threats, vulnerabilities, and unauthorized access. It involves implementing controls, policies, and technologies to ensure the confidentiality, integrity, and availability of hardware, software, and data. This discipline is critical for safeguarding organizational assets against cyberattacks, data breaches, and operational disruptions.

Also known as: Infosec Infrastructure, IT Infrastructure Security, Network Security, System Security, Cyber Infrastructure Protection

Why learn Infrastructure Security?

Developers should learn Infrastructure Security to build and maintain resilient systems, especially in roles involving DevOps, cloud engineering, or system administration. It is essential for securing applications in production, complying with regulations like GDPR or HIPAA, and preventing incidents such as DDoS attacks or data leaks. Use cases include hardening cloud infrastructure (e.g., AWS, Azure), implementing network segmentation, and managing access controls in CI/CD pipelines.
