This module focuses on preventing one of the most common and devastating supply chain attacks: credential leakage. You will learn the mechanics of secrets detection, including how scanners use regular expressions, entropy analysis, and contextual awareness to identify API keys, passwords, and tokens. We will cover the integration of secret scanning into pre-commit hooks and CI/CD pipelines, the critical process of credential rotation, and the transition to centralized secrets management solutions like HashiCorp Vault or AWS Secrets Manager. The module culminates in a hands-on guided lab where you will identify leaked secrets in a Git history, rotate the compromised credentials, and implement automated prevention controls.
