DevSecOps and DevOps for Linux: The Foundations

Linux delivery work spans far more than a deployment pipeline. In DevSecOps and DevOps for Linux: The Foundations, Marco Antonio Carcano brings team practices, command-line fluency, software engineering, security, and operations into one connected learning path—showing how the pieces of a reliable delivery practice relate.

Start with the way teams work

The book begins with collaboration and solution lifecycles before turning to Agile, Lean, Scrum, and Kanban. This opening gives the technical material an organizational frame: tools matter, but so do shared processes, clear scope, and continuous improvement.

Build fluency at the Linux command line

From Bash and command-line utilities to regular expressions, grep, sed, and AWK, the early technical chapters develop practical skills for working with systems and data. XML, JSON, and YAML processing extend that foundation, with Python appearing alongside these formats.

Follow a project through the toolchain

Rather than treating each technology as an isolated topic, the book develops an example Python project across its coverage of unit testing, packaging, build automation, Git, and code-compliance checks. The sequence helps make the relationships between development tasks and delivery practices easier to follow.

Bring security into everyday engineering

Security topics include vulnerability scanning, system security, GPG, and X.509 certificates and PKI. The book also covers HTTP, TLS, LDAP, and service protocols such as SOAP and REST, connecting application work with the systems and communication layers around it.

Containers, CI/CD, and infrastructure automation

Docker and Podman lead into Kubernetes, Helm, Rancher, and Gitea, with further coverage of CI/CD workflows, Git, SSH, and Ansible playbooks, roles, and collections. Together, these subjects give the book a distinctly Linux-focused view of how software is built, secured, packaged, and operated.

Who may find it useful

Students establishing core Linux and Python skills, as well as engineers developing toward DevOps or DevSecOps responsibilities, will find a broad route through the subject. The book combines conceptual groundwork with practical tool-oriented material, making it useful for readers who want to understand not only individual commands and platforms, but where they fit in the larger workflow.
