Docker Security Fundamentals with Linux and Swarm

Containerization has revolutionized software deployment, but it also introduces unique security risks that every developer and administrator must address. This text-based course provides a clear, conceptual path to securing your containerized applications from the ground up. You will start by understanding core Linux kernel isolation mechanisms, learn how to configure secure swarm environments, and discover how to manage sensitive data safely. What you will learn: Understand foundational container security concepts and threat models; Configure Linux namespaces, cgroups, and capabilities for container isolation; Implement secure Docker Swarm architectures with encrypted communication; Manage application credentials safely using built-in secrets management; Verify image integrity using cryptographic signing and vulnerability scanning; Apply security profiles like AppArmor and Seccomp to restrict container privileges. The course begins with essential security terminology and system administration basics before guiding you through practical configuration strategies and production-ready defense techniques. This course is designed for system administrators, DevOps engineers, and developers who are new to container security and want to establish a strong security posture.
