Did you know that over 83% of organizations experienced at least one successful application exploit in the last 12 months? This statistic from a recent cybersecurity report highlights the critical importance of securing our code repositories and development workflows. As the world's leading platform for version control and collaboration, GitHub has an important role in the software development life cycle for millions of developers and organizations. In this guide, we'll explore nine essential GitHub security best practices that will help you protect your code, your team, and your users in 2024 and beyond.
One of the most fundamental steps in securing your GitHub organization account and repositories is enabling Two-Factor Authentication (2FA). This simple yet powerful security measure adds an extra layer of protection beyond just your password.
1. Go to your GitHub account settings

4. Choose your preferred 2FA method (GitHub Mobile, Passkey, or Authenticator App)
Pro tip: We recommend using Authenticator apps like Google Authenticator or Authy for the most secure 2FA experience because the authentication code changes every few seconds.
Proper access control is important for maintaining the security of your GitHub repositories, especially when working in teams or on open-source projects.
Here's a simple table illustrating how you might structure team permissions for a typical software project:
By implementing these access control measures, you can significantly reduce the risk of unauthorized changes to your codebase and limit the potential impact of a compromised account.
To set role-based access in your GitHub organization, Go to the settings of your organization account:

By leveraging these built-in security features, you can proactively identify and address potential security issues in your codebase.
Branch protection rules are a powerful feature in GitHub that allows you to enforce certain workflows and prevent unauthorized changes to important branches.
1. Go to your repository's settings
2. Click on "Branches"
This screenshot displays the GitHub repository settings, specifically the "Branches" section, where users can manage branch protections, default branches, and related settings. It guides users in figuring out how branches are handled within their repository.
3. Under "Branch protection rules," click "Add branch ruleset"
This screenshot displays the branch protection rules section in the GitHub repository settings, emphasizing the option to add a new ruleset for enhanced branch protection.
4. Add a new ruleset and name it. You can also define a bypass list to exempt teams or users from going beyond such rules.
The above screenshot displays the option to create a new branch protection ruleset by naming it and specifying a bypass list. Users can exempt certain teams or individuals from the defined rules, allowing for more flexible branch management while maintaining security standards.
5. Configure the desired protection settings and add a target branch.
Here, the screenshot allows users to configure branch protection settings to specify the desired protections and select the target branch to which these rules will apply.
6. Click "Create" to save the changes.
Pro tip: Start with strict protection rules on your main branch and gradually apply them to other important branches as your team becomes comfortable with the workflow.
Continuous Integration and Continuous Deployment (CI/CD) pipelines are essential for modern software development, but they can also introduce security risks if not properly secured. Here are some best practices for securing your CI/CD pipelines on GitHub:
Here's an example of how to securely use a secret in a GitHub Actions workflow:
name: Deploy to Production
on:
push:
branches: [ main ]
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Deploy to server
env:
SERVER_SSH_KEY: ${{ secrets.SERVER_SSH_KEY }}
run: |
echo "$SERVER_SSH_KEY" > deploy_key.pem
chmod 600 deploy_key.pem
ssh -i deploy_key.pem user@example.com './deploy.sh'
rm deploy_key.pem
In this example, we're using a GitHub secret (SERVER_SSH_KEY) to securely store and use an SSH key for deployment. The secret is never exposed in logs or to unauthorized users.
To set the secrets for your repository
1. Go to the repository “Settings”
2. Click on “Secrets and Variables”
This screenshot displays the "Secrets and Variables" section within the repository settings, where users can manage environment secrets. It emphasizes the importance of securing sensitive information necessary for the repository's operation.

Here, the screenshot highlights the "New Environment" form, prompting users to input a name for their new environment. It emphasizes the simplicity of creating custom environments for managing deployment workflows effectively.
5. Click on “Configure environment” so that it will start managing your key environments. After that, you can keep on adding secret keys and its values to the same environment.
The above screenshot highlights the "Configure Environment" button, allowing users to start managing their key environments. Once clicked, users can add secret keys and their corresponding values to the environment, facilitating secure management of sensitive information during deployments.
Here, this screenshot highlights the "Add Secret" option, enabling users to input the name and value of a new secret. This feature allows for the secure storage of sensitive information utilized in workflows and deployments within the repository.
6. Add your secret and now you will be able to use it in your deployment scripts.
Secret scanning is a security feature that helps prevent the accidental exposure of sensitive information in your GitHub repositories. It automatically detects tokens, private keys, and other secrets that have been committed to your repository.
Here, it highlights the "Secret Scanning" feature in the repository settings, displaying the option to disable scanning. Enabling secret scanning helps identify and protect sensitive information in code, ensuring that no credentials or secrets are exposed during development and collaboration.
Monitoring your repository activity is crucial for detecting and responding to potential security threats quickly. GitHub provides several tools to help you keep track of what's happening in your repositories.
You can visit it from the “Insights” Tab of your project
The screenshot highlights the "Insights" tab in the repository, where users can monitor activity to spot and address any security issues. GitHub provides tools here to help track what's happening in your repositories, making it easier to stay updated on changes and activities.
A clear and comprehensive security policy is essential for maintaining the security of your GitHub repositories and guiding your team's security practices. It also allows contributors or users to report bugs related to security.
1. Go to the Security tab of your project
2. Click on “Set up a Security Policy”
Here, the above screenshot highlights the "Set up a Security Policy" option in the Security tab of your project. Users can create a SECURITY policy file by following this prompt, helping outline the repository's security guidelines and procedures.
GitHub recommends creating a SECURITY.md file in the root of your repository to communicate your security policy. Here's a basic template:
