Container Security

Container security is a set of practices, tools, and policies designed to protect containerized applications and their infrastructure throughout the entire lifecycle, from development to production. It focuses on securing container images, runtime environments, orchestration platforms, and the underlying host systems to prevent vulnerabilities, misconfigurations, and attacks. This includes aspects like vulnerability scanning, access control, network segmentation, and compliance monitoring.

Also known as: ContainerSec, Docker Security, Kubernetes Security, CIS Benchmarks for Containers, Container Hardening

Why learn Container Security?

Developers should learn container security to ensure the safety and reliability of applications deployed in containers, especially in cloud-native and microservices architectures where containers are widely used. It is critical for preventing data breaches, meeting regulatory requirements (e.g., GDPR, HIPAA), and maintaining trust in production environments, such as when using Kubernetes or Docker in DevOps pipelines.
