Find out if your GitHub repository contains sensitive information such as password, secret keys, confidential information, etc.
GitHub is used by millions of users to host and share codes. It’s fantastic, but sometimes you/developers/code owners can accidentally dump confidential information in a public repository, which can be a disaster.
There are many incidents where confidential data was leaked on GitHub. You can’t eliminate human error but can take action to reduce that.
How do you ensure your repository doesn’t contain a password or key?
But in reality, you can’t control other people’s behavior if working in a team.
BTW, if you use Git to initialize and deploy your application, it creates .git folder, and if accessible over the Internet, it may expose sensitive confirmation – which you don’t want and should consider blocking .git URI.
The following solutions help you to find mistakes in your repository.
GitHub’s secret scanning feature is a powerful tool that detects accidental secrets hidden in your code, safeguarding against data leaks and compromises. It works seamlessly for both public and private repositories, meticulously combing through every nook and cranny to uncover any slipped secrets.
But its capabilities continue. Once a secret is discovered, GitHub takes proactive measures by alerting the respective service providers, prompting them to mitigate any potential risks swiftly. Regarding private repositories, GitHub goes the extra mile by notifying organization owners or administrators, ensuring that the right individuals within your team are immediately made aware of the situation.
To provide continuous visibility, warnings are prominently displayed within the repository, serving as a clear signal for you and your team to take prompt action. GitHub’s secret scanning feature acts as your vigilant ally, diligently working to ensure that no secret goes unnoticed and your projects remain secure.
Embrace the power of secret scanning and code confidently, knowing your sensitive information is protected.
Let me introduce you to git-secrets, a tool that can save us from the embarrassment of accidentally adding secrets to our Git repositories. It scans commits, commit messages, and merges to prevent secret leakage in our code.
To get started on Windows, we simply run the install.ps1 PowerShell script. It copies the necessary files to an installation directory and adds them to our user PATH. This makes git-secrets easily accessible from anywhere in our development environment.
Once installed, git-secrets becomes our watchful guardian, checking if any commit, commit message, or merge history matches our configured prohibited patterns. If it detects a match, it rejects the commit, preventing sensitive information from slipping through the cracks.
We can add regular expression patterns to a .gitallowed file in the repository’s root directory to fine-tune git-secrets. This helps filter out any lines that might trigger a warning but are legitimate, striking the right balance between security and convenience.
When scanning a file, git-secrets extract all lines that match prohibited patterns and provide detailed information, including file paths, line numbers, and the matched lines. It also checks whether the matched lines match our registered allowed patterns. The commit or merge is considered safe if allowed patterns cancel out all flagged lines. However, git-secrets block the process if any matched lines don’t match an allowed pattern.
While using git-secrets, we need to be cautious. Prohibited patterns should not be too broad, and allowed patterns should not be too permissive. Testing our patterns using ad-hoc calls to git secrets –scan $filename ensures they work as intended.
If you’re eager to dive deeper into git-secrets or want to contribute to its development, you’ll find the project on GitHub. It’s an open-source project that encourages community contributions. Join the community and make a difference!
With git-secrets, we can code confidently, knowing that accidental secrets won’t jeopardize our projects. Let’s embrace this tool and keep our sensitive information secure.
I’ve got this exciting news: Repo-supervisor is a powerful tool that detects secrets and passwords in your code. Installing it is a breeze—simply add a webhook to your GitHub repository. Repo-supervisor offers two modes: scanning pull requests on GitHub or scanning local directories from the command line. Choose the mode that suits you best.
To embark on your git-secrets journey, simply visit the GitHub repository and download the most recent release. There, you’ll discover bundles tailored for AWS Lambda deployment and a user-friendly CLI mode. With the CLI mode, you can dive right in without any extra setup, while the pull request mode necessitates deploying to AWS Lambda. Choose the option that suits your needs and start harnessing the power of git-secrets to bolster the security of your codebase!
In CLI mode, provide a directory as an argument, and Repo-supervisor scans supported file types, processing each file with a tokenizer specific to its type. It runs security checks on extracted strings and provides clear reports in plain text or JSON format.
For pull request mode, Repo-supervisor processes webhook payloads, extracts modified files, and performs security checks on the extracted strings. If issues are found, it sets the CI status to error, linking to the report. No issues mean a successful CI status.
Repo-supervisor is an amazing code inspector that keeps our secrets and passwords secure. It ensures the integrity of our codebase, which is crucial in our professional lives.
Give Repo-supervisor a try! Install it, configure the webhook, and let it scan for secrets and passwords. Enjoy the extra layer of security!
