Welcome to the final installment in our series on quantum-safe cryptography! In this post, we’ll explore how to integrate cryptographic discovery methods into your CI/CD pipeline, focusing on repository events like commits and pull requests.
The Quantum Threat
As quantum computers evolve, they pose a significant threat to many of our current cryptographic algorithms. Notably, RSA and ECDSA, which form the backbone of much of our digital security, are vulnerable to quantum attacks. It’s crucial to identify and replace these algorithms with quantum-resistant alternatives.
Objective
Our goal is to implement an Automated Cryptography Discovery & Inventory (ACDI) tool within the CI/CD pipeline that scans for quantum-vulnerable cryptographic algorithms. This tool will be triggered by repository events such as commits and pull requests, providing immediate feedback to developers about potential security risks.
Implementation Steps
1. Repository Setup
First, clone the repository containing your source code:
git clone https://github.com/your-organization/crypto-vulnerable-repo.git
cd crypto-vulnerable-repo
2. Simulating Development Workflow
To test our discovery method, we’ll make a change to the codebase. Let’s add a print statement to a Java file that uses vulnerable cryptographic methods:
public class CryptoExample {
public static void main(String[] args) throws Exception {
System.out.println("Hello World"); // Added print statement
// Existing cryptographic code
KeyPairGenerator keyPairGen = KeyPairGenerator.getInstance("RSA");
keyPairGen.initialize(2048);
KeyPair pair = keyPairGen.generateKeyPair();
PublicKey publicKey = pair.getPublic();
PrivateKey privateKey = pair.getPrivate();
Signature ecdsa = Signature.getInstance("SHA256withECDSA");
ecdsa.initSign(privateKey);
ecdsa.update("Sample message".getBytes());
byte[] signature = ecdsa.sign();
}
}
3. Committing Changes
Commit the changes to the repository:
git add .
git commit -m "Added a print statement to CryptoExample.java"
4. Creating a Pull Request
Push the changes to a new branch and create a pull request:
git push origin new-feature-branch
Then, use your repository hosting service (GitHub, GitLab, etc.) to create a pull request comparing your new branch against the main branch.
5. Setting Up the CI/CD Pipeline
The heart of our discovery method lies in the CI/CD pipeline. We’ll use a static analysis tool to scan for vulnerable cryptographic algorithms. Here’s an example using GitHub Actions and SonarQube:
name: Code Scan
on:
pull_request:
branches:
- main
jobs:
scan:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Set up JDK 11
uses: actions/setup-java@v1
with:
java-version: '11'
- name: Run static analysis
run: |
wget https://sonarcloud.io/static/cpp/build-wrapper-linux-x86.zip
unzip build-wrapper-linux-x86.zip
sonar-scanner -Dsonar.projectKey=my-project-key \
-Dsonar.organization=my-organization \
-Dsonar.host.url=https://sonarcloud.io \
-Dsonar.login=$SONAR_TOKEN
This workflow will trigger a code scan using SonarQube whenever a pull request is created on the main branch.
6. Validating the Discovery
The final step is to ensure our discovery tool accurately identifies and reports quantum-vulnerable algorithms. The output should appear in the repository console or pull request page, looking something like this:
File: src/main/java/com/example/CryptoExample.java
Line: KeyPairGenerator.getInstance("RSA");
Warning: Usage of RSA encryption, which is vulnerable to quantum attacks. Consider migrating to quantum-safe algorithms.
Line: Signature.getInstance("SHA256withECDSA");
Warning: Usage of ECDSA signature, which is vulnerable to quantum attacks. Consider migrating to quantum-safe algorithms.
Best Practices and Considerations
- Regular Updates: Keep your static analysis tools updated to ensure they can detect the latest known vulnerabilities.
- False Positives: Be prepared to handle false positives. Some legitimate uses of these algorithms may be flagged.
- Education: Use this process as an opportunity to educate your team about quantum-safe cryptography.
- Gradual Migration: Plan for a gradual migration to quantum-safe algorithms, prioritizing the most critical parts of your system.
- Monitoring: Implement monitoring to track the prevalence of quantum-vulnerable algorithms in your codebase over time.
