Application security has become a critical concern for organizations worldwide in today’s rapidly evolving digital landscape. With cyber threats becoming increasingly sophisticated, it is essential to integrate robust security measures directly into the software development lifecycle. GitHub Advanced Security is a comprehensive solution that empowers developers to identify and mitigate vulnerabilities early, ensuring code safety and integrity from the outset.

Introduction to GitHub Advanced Security

GitHub Advanced Security is a developer-focused application security offering that seamlessly integrates into your existing workflow. Embedding security tools directly within the development process enables teams to proactively detect and address potential vulnerabilities before they can be exploited in production environments. This proactive approach not only enhances the security posture of your applications but also streamlines the development process by reducing the need for retroactive fixes.

Core Capabilities

GitHub Advanced Security provides three primary capabilities to bolster your code’s security:

1. Code Scanning with CodeQL

Code Scanning leverages Static Application Security Testing (SAST) techniques to analyze your codebase for security vulnerabilities and coding errors. Using CodeQL, GitHub’s semantic code analysis engine, it performs deep analyses to identify various issues, from common vulnerabilities to complex logic errors.

• Automated Analysis: Automatically scans code as it’s created or updated, providing near-instant feedback.
• Customizable Queries: Allows customization of analysis with user-defined queries to target specific vulnerabilities or adhere to organizational policies.
• Actionable Insights: Provides detailed information about each detected issue, including the code’s location and remediation guidance.

2. Secret Scanning

Secret Scanning monitors your repositories for known secret formats, such as API keys, tokens, and private cryptographic keys. Detecting exposed secrets helps prevent unauthorized access and potential breaches resulting from leaked credentials.

• Real-Time Monitoring: Continuously scans for secrets in your code, including in commit history.
• Immediate Alerts: Notifies repository administrators and relevant team members upon detection of secrets.
• Integration with Partners: Collaborates with service providers to automatically revoke or rotate exposed secrets when possible.

3. Dependency Review

Dependency Review provides insights into the dependencies added or updated in pull requests, highlighting any that contain known vulnerabilities.

• Pull Request Integration: Analyzes changes in dependencies directly within pull requests.
• Vulnerability Alerts: Identifies and flags dependencies with known security advisories.
• Version Guidance: Suggests safer versions of dependencies when vulnerabilities are detected.

Trial Features Available

Understanding the importance of accessible security tools, GitHub offers free code scanning and dependency review features on public repositories. This allows individual developers and organizations to trial these capabilities without any commitment, fostering an environment where security is accessible to all projects, big or small.

How to Enable Code Scanning and CodeQL

Getting started with code scanning is straightforward and can be done in two primary ways:

• Option 1: Test on a public repository that you maintain. This allows you to experience code scanning in the context of your own projects.
• Option 2: Utilize a sample repository that GitHub provides, such as Juice Shop, an intentionally vulnerable application designed for security training.

Note: Administrator permissions are required to set up code scanning workflows in a repository.

Code Scanning in Action with Juice Shop

Let’s walk through enabling code scanning using the Juice Shop repository to illustrate the process:

Step 1: Fork the Repository

Navigate to the Juice Shop repository and click on the Fork button in the upper-right corner. This creates a copy of the repository under your GitHub account, allowing you to experiment without affecting the original project.

Step 2: Enable Workflows

In your forked repository:

1. Click on the Actions tab. If prompted, enable GitHub Actions for the repository.
2. Find the “CodeQL Analysis” workflow, which is preconfigured for code scanning.
3. Click on the workflow to review it, then click “Enable workflow” if necessary.

Step 3: Run a Scan

To initiate a scan:

1. Go to the Actions tab and select the CodeQL Analysis workflow.
2. Click “Run workflow”, and select the desired branch (e.g., main), and confirm.
3. The workflow begins with executing and analyzing your codebase for vulnerabilities.

Step 4: Check Alerts

Once the workflow is completed:

1. Navigate to the Security tab of your repository.
2. Under “Code scanning alerts”, you’ll see a list of detected vulnerabilities and errors.
3. Click on individual alerts to view detailed information, including the affected code and remediation guidance.

Understanding Code Scanning Results

Interpreting and acting on code scanning results is crucial for improving your code’s security.

Prioritize Alerts

• Severity Levels: Alerts are categorized by severity (e.g., high, medium, low). Focus first on high-severity issues that pose significant risks.
• Relevance: Assess the context of each alert to determine its relevance to your application.

Remediation Guidance

• Detailed Analysis: Each alert provides a description, affected code snippets, and recommendations.
• Learn and Apply: Use this information to understand the vulnerability and implement the suggested fixes.
• Collaborate: Engage with team members by assigning alerts or discussing solutions directly within GitHub.

Filter Results

• Search and Filter: Utilize filters to sort alerts by severity, file path, or vulnerability type.
• Manage Alerts: Mark alerts as resolved, won’t fix, or false positives to keep your dashboard organized.

Integrating GitHub Advanced Security into Your Workflow

Embracing a security-first mindset involves integrating security practices seamlessly into your development workflow.

For Developers

• Shift Left: Identify and resolve vulnerabilities during development rather than after deployment.
• Immediate Feedback: Receive real-time alerts on code changes that introduce vulnerabilities.
• Continuous Learning: Enhance your security knowledge through exposure to common vulnerabilities and remediation techniques.

For Security Teams

• Centralized Oversight: Monitor security across all repositories from a unified dashboard.
• Policy Enforcement: Implement organization-wide security policies and ensure compliance.
• Efficient Collaboration: Work closely with developers to address vulnerabilities promptly.

For Product Owners and DevSecOps Architects

• Risk Management: Gain insights into the security posture of your products to inform decision-making.
• Compliance: Ensure adherence to industry regulations and standards through robust security practices.
• Strategic Planning: Allocate resources effectively by understanding prevalent security issues.

Code Scanning Examples
