GitHub Security: Managing Sensitive Data and Repository Policies

Securing your codebase is just as important as writing the code itself, yet accidental leaks of credentials and unpatched dependencies remain major risks. Understanding how to leverage built-in platform tools ensures your projects remain secure from the very first commit. This written course guides you through the core concepts of repository security, helping you establish a proactive defense strategy. You will transition from basic repository setup to implementing automated security scans and managing sensitive data with confidence. What you'll learn: - Understand foundational security concepts, threat modeling, and how to write a clear repository security policy. - Configure secret scanning and push protection to prevent accidental exposure of API keys and credentials. - Manage repository access controls, branch protection rules, and environment secrets. - Apply automated dependency alerts using Dependabot to identify and patch vulnerable libraries. - Implement security advisories and standard response workflows for newly discovered threats. You will start with essential security terminology and repository configurations before moving on to practical text-based walkthroughs of automated scanning, secret management, and policy enforcement. This course is designed for beginner developers, project managers, and security newcomers who want to protect their codebases. No prior security experience is required.
