How to Automatically Run Detect-Secrets with Git Pre-Commit Hooks | Secure Your Code with Pre-Commit

Summary

The script explains how to use 'detect-secrets' with the 'pre-commit' framework to prevent sensitive data from being committed to code repositories. It covers installing necessary software, configuring 'pre-commit config.yaml', creating a 'secrets.baseline' file to list known non-secrets, and setting up hooks to automatically scan for secrets during git commits. It also discusses handling false positives and updating the baseline file.

Takeaways

• 🔐 **Use detect-secrets**: Utilize detect-secrets to identify sensitive information like credentials, API keys, and passwords in source code.
• 🛠️ **Pre-commit Framework**: Have the pre-commit framework installed to automatically run scripts on code commits.
• 📦 **Installation**: Install or verify the installation of pre-commit and detect-secrets using the PIP command.
• 📄 **Configuration File**: Create a `.pre-commit-config.yaml` file at the root of your local repository to configure pre-commit hooks.
• 🔑 **Secrets Baseline**: Generate a baseline file listing tokens that resemble secrets but are confirmed safe to avoid false positives.
• 🔍 **Scan Repository**: Use detect-secrets to scan your repository to create an initial secrets.baseline file.
• 📝 **Commit Trigger**: Configure the script to run detect-secrets on both commit and push actions.
• 🚫 **Prevent Commits**: If detect-secrets finds potential secrets, it will prevent the commit from being completed until resolved.
• ❌ **Handle False Positives**: Mark false positives in the code with a comment to allow commit and update the baseline file.
• 🔄 **Update Baseline**: Regularly update the baseline file to include new confirmed non-secrets to improve accuracy over time.
• 👥 **Team Communication**: Use comments in the code to communicate findings and handling to other team members.
