Git

Git is a widely used version control system that has revolutionized the way programmers manage and collaborate on software development projects. This tool has become a fundamental pillar for both programmers and SecDevOps teams, and here we will explain why.

Introducción​

Git is a distributed version control system, created by Linus Torvalds in 2005. Its main function is to track changes in the source code and facilitate collaboration between developers on a project. Through Git, programmers can keep an accurate record of modifications made to code, allowing them to:

  1. Version History: Git keeps a complete history of all previous versions of the code. This means you can track who made what changes, when and why. This is invaluable for troubleshooting, identifying errors or reverting to previous versions if necessary.
  2. Parallel Work: Several programmers can work on the same project simultaneously without interfering with each other's work. Git makes it easy to merge changes made by different team members.
  3. Efficient Collaboration: Git enables developers to collaborate effectively, even on globally distributed projects. Remote repositories and development branches facilitate collaboration and code review.
  4. Error Tracking: It is easier to identify when and how errors were introduced in the code. You can use Git to "go back" in history and isolate the source of a problem.

Importancia para los Programadores​

  • Gestión de código eficiente: Git proporciona herramientas para gestionar el código de manera organizada y efectiva. Branches allow experimentation and development of new features without affecting the main branch (e.g., "master" or "main").
  • Revisión de código: Facilita la revisión de código entre miembros del equipo. Pull requests allow other developers to review and comment on modifications before merging them.
  • Control individual: Cada programador puede trabajar en su propio repositorio local, lo que brinda un alto grado de autonomía y flexibilidad.
  • Convención de commits Otro aspecto importante para los programadores es tener una convención en los mensajes de los commits para que sea fácil de leer por todo el equipo. Si la empresa no tiene una convención propia, se puede usar Conventional Commits.

Fundamental to SecDevOps​

Git plays a key role in the adoption of SecDevOps practices, which seek to integrate security into all stages of the software development lifecycle. Herein lies its importance:

  • Secure Version Control: Git guarantees the integrity of the source code, preventing unauthorized modifications. This is essential to protect against attacks and to guarantee the confidentiality and integrity of the code.
  • Auditing and Tracing: Git provides a complete history of changes, which facilitates security auditing and tracing of any suspicious activity.
  • Secure Collaboration: In a SecDevOps environment, secure collaboration is essential. Git allows you to implement security policies and control who has access to repositories and branches.
  • Automation and Continuous Deployment: Git integrates seamlessly with automation and continuous deployment tools, ensuring secure and efficient software delivery.

If you are interested in learning Git from scratch or improving your Git skills, there are valuable resources available online. One of them is Learn Git Branching, an interactive platform that allows you to experiment with different Git commands in a virtual environment. Through hands-on exercises, you will gain a better understanding of key Git concepts such as branches, merges and conflicts.

In addition, if you would like to explore a specific Git workflow methodology, we recommend you consult the Git Flow reference sheet. This guide will provide you with detailed information about Git Flow, a popular strategy for organizing collaborative software development, with specific rules and practices for branch and version management.

In short, Git is a fundamental tool for both programmers and SecDevOps teams. It facilitates collaboration, code management and security, which contributes to more efficient, secure and quality-oriented software development.
