Book synopsis

Secure Containers. Verify Supply Chains. Enforce Zero-Trust - This Is the New Era of Container Security.

Containers run the world's infrastructure - but most are still deployed with default privileges, insecure images, and weak runtime visibility. Mastering Container Security rewrites that playbook with a complete, practical guide to hardening Podman, Rootless Docker, and modern Linux container stacks for real-world DevSecOps environments.

Built for 2025 and beyond, this book bridges security engineering, cloud-native architecture, and hands-on DevOps practice. You'll move from understanding the threat landscape to building fully rootless, signed, monitored, and policy-driven container platforms using today's most advanced open-source tools.

Inside You'll Learn How To

• Build rootless Podman and Docker containers with secure user namespaces, UID mapping, and kernel isolation.
• Apply CIS Benchmarks, NIST SP 800-190, and MITRE ATT&CK mappings to real-world container environments.
• Harden hosts with Seccomp, AppArmor, SELinux, and No New Privileges (NNP).
• Generate and sign SBOMs with Syft, Trivy, and cosign, then enforce image integrity in Harbor and GitHub Actions pipelines.
• Detect runtime threats with Falco and Tetragon, using eBPF-based auditing for privilege escalation and container escapes.
• Automate security controls across CI/CD pipelines with Jenkins, Drone CI, and OPA policy gates.
• Integrate Zero-Trust principles, workload attestation, and TPM-based verification for next-gen confidential computing.

Each chapter ends with a Practice Lab, ensuring you build, test, and verify every technique - culminating in a full-stack DevSecOps project that deploys a signed, monitored, and policy-enforced container platform from scratch.

Who This Book Is For

• DevSecOps Engineers securing containers in regulated or high-trust environments.
• System Administrators and SREs building hardened rootless infrastructures.
• Cloud-Native Developers embedding security into the build and deploy pipeline.
• Security Analysts seeking real-time detection and response visibility at the container level.

Modern, Hands-On, and Enterprise-Ready

Every configuration, command, and YAML example in this book has been tested on Podman, Docker, and Linux distributions (Fedora, Ubuntu, RHEL, Rocky Linux) - ensuring reproducibility in both enterprise clusters and homelab environments.

From image signing and policy enforcement to eBPF-driven runtime defense, this book delivers the complete blueprint for container security maturity in the age of rootless and trustless DevOps.

Protect your containers. Prove your trust. Automate your defense.
