Modern DevSecOps (The Hard Way)
Modern DevSecOps (The Hard Way)
Master the art of integrating security into every phase of the software development lifecycle. This course avoids 'magic' GUI tools and focuses on the command line, manual configuration, and deep technical understanding. You will build secure CI/CD pipelines, harden Linux servers, automate vulnerability scanning with Bash scripts, and monitor infrastructure using Prometheus and Grafana. The discipline follows a 'Hard Way' philosophy: finding and patching a daily injected security flaw to build true resilience.
