DevOps automation must include security. GitLab provides native security scanning.

Introduction: The Shift from Manual to Automated DevOps In the early days of software development, deploying code was a manual, nerve-wracking affair. System administrators would SSH into servers, pull code from repositories, run build commands, and restart services. This process was error-prone, slow, and unscalable. DevOps automation must include security

include: - template: Security/Secret-Detection.gitlab-ci.yml These security jobs run automatically, enforcing "shift-left" security. Environments Track deployments by defining environments:
