Docker Container Security with MAC and Seccomp

Container security is a critical pillar of modern cloud infrastructure, yet default configurations often leave systems vulnerable to privilege escalation. This text-only course guides you through securing Docker containers using Linux kernel security mechanisms. You will learn to restrict container capabilities and prevent unauthorized system calls. Starting with foundational cybersecurity concepts and basic Linux security architecture, this course guides you through practical configurations to isolate workloads. You will understand how Docker interacts with system resources and how to write custom security profiles. What you will learn: Understand the core principles of Mandatory Access Control (MAC) and secure computing (seccomp) in Linux; Configure AppArmor and SELinux profiles to restrict container access to host resources; Write and apply custom seccomp JSON profiles to limit permitted system calls; Implement modern container hardening best practices, including zero-trust isolation and minimal privilege configurations; Debug and audit blocked system calls using host logging tools. The course starts with essential security concepts and basic terminology before moving into practical configuration files and policy design. Designed for DevOps engineers, system administrators, and developers looking to secure their container deployments, this course requires only basic command-line familiarity. Take control of your container security and protect your infrastructure from runtime exploits.
