Why You Need a Continuous Testing Strategy: CrowdStrike Falcon Edition

Continuous Testing: An Essential Practice 

Continuous testing is the process of executing automated tests as part of the software delivery pipeline to obtain immediate feedback on the business risks associated with a software release. This practice is integral to modern DevOps and Agile methodologies, ensuring that code changes do not introduce new vulnerabilities or issues. 

Benefits of continuous testing include: 

• Immediate Feedback: Continuous testing provides instant feedback on code changes, allowing developers to address issues before they escalate. 

• Increased Coverage: Automated tests run continuously, covering a wide range of scenarios and configurations, ensuring thorough validation. 

• Early Detection: Identifies issues early in the development cycle, reducing the cost and complexity of fixes. 

How Continuous Testing Applies to CrowdStrike 

If CrowdStrike had implemented continuous testing for their content updates, they would have detected the false positives and performance issues during the development phase — well before deployment. This early detection could have prevented the widespread impact on their users. The massive outage that affected millions of Microsoft devices globally is predicted to cost Fortune 500 companies approximately $5.4 billion in direct financial losses.  

4 Ways to Enhance Your Continuous Testing Strategy 

Understanding the need for a continuous testing strategy is one thing. Implementing the best practices and processes needed to achieve continuous testing in quite another. 

To create an effective continuous testing strategy, it is helpful to use the different tools and techniques at your disposal. Four such ways to help achieve continuous testing include shifting left, utilizing test data, implementing service virtualization, and incorporating AI.  

Let us explore each of these methods in more detail.  

Shift Left: Integrating Testing Early in the Development Process 

The shift-left approach involves moving testing earlier in the software development lifecycle. This proactive strategy ensures that issues are identified and resolved sooner, reducing the risk of defects in production. 

Advantages of shift-left testing include: 

• Early Bug Detection: Finds defects early when they are easier and cheaper to fix. 

• Improved Quality: Enhances overall product quality by integrating testing into every stage of development and provides a better user experience. 

• Faster Releases: Streamlines the development process, enabling quicker and more reliable releases. 

How Shift Left Applies to CrowdStrike 

By adopting a shift-left approach, CrowdStrike could have identified the issues with the content update during the initial stages of development. Early testing would have caught the false positives and performance issues, allowing for adjustments before the update reached end-users. 

Utilizing Test Data: Realistic and Comprehensive Testing 

Effective testing requires realistic and comprehensive test data that accurately represents the production environment. This ensures that tests mimic real-world conditions, providing a more accurate assessment of software performance and behavior. 

Some important benefits of using test data include: 

• Realistic Scenarios: Simulates actual user behavior and system interactions. 

• Comprehensive Coverage: Ensures that edge cases and uncommon scenarios are tested. 

• Improved Accuracy: Increases the reliability of test results by using data that mirrors production. 

How Test Data Applies to CrowdStrike 

If CrowdStrike had utilized realistic and comprehensive test data, they could have better simulated the conditions under which the content update would operate. This would have helped identify the performance degradation and false positives, allowing for corrective actions before deployment. 

Implementing Service Virtualization: Enhancing Testing Capabilities 

Virtual services are simulated versions of components or services and are used in place of actual services during testing to avoid dependencies and other testing bottlenecks. This approach is particularly useful for testing in complex, interdependent environments. 

Advantages of service virtualization include: 

• Isolated Testing: Allows testing of specific components in isolation, identifying issues more precisely. 

• Continuous Availability: Provides a stable testing environment that is always available, reducing downtime. 

• Cost-Effective: Reduces the need for costly test environments and resources. 

How Service Virtualization Applies to CrowdStrike 

By implementing virtual services, CrowdStrike could have simulated the interactions between the content update and other system components. This would have allowed them to identify any conflicts or performance issues in a controlled environment, ensuring that the update functioned correctly across different scenarios. 

The Power of AI in Testing 

AI-based testing leverages artificial intelligence and machine learning to enhance traditional testing methods. This approach can analyze vast amounts of data, predict potential issues, and optimize the testing process to ensure comprehensive coverage and accuracy. 

Here are some great ways to use AI as part of your continuous testing strategy: 

1. Automated test generation and execution. 

2. Root cause analytics and anomaly detection. 

3. Intelligent test data generation. 

4. Eliminate test script maintenance. 

Moving Forward: Implementing a Robust Continuous Testing Framework 

Cybersecurity is an industry where every update must be both swift and flawless. These testing strategies are not just best practices—they are essential. Implementing these approaches would have enabled CrowdStrike to catch the issues with their content update early in the development process, preventing disruptions for their users and maintaining the integrity of their highly regarded Falcon platform. 

The CrowdStrike Falcon content update issue serves as a learning opportunity for all in the software development and cybersecurity fields. Implementing a comprehensive testing framework is crucial to prevent similar issues in the future. Here are some steps to consider: 

1. Shift left, automate where possible, and leverage continuous testing. Automated testing can significantly speed up the process and ensure consistency, particularly for unit, integration, and regression testing. This means running tests automatically in the SDLC as part of a CI/CD pipeline from the first build (shifting left!) all the way to end-to-end testing the entire integrated environment. 

2. Diversify testing environments. Testing in a variety of environments helps uncover issues that might only occur under specific conditions, ensuring broader compatibility. Supporting testing environments requires utilizing virtual services, synthetic test data as well as test data management solutions where possible.

3. Continuous monitoring and feedback. Post-deployment monitoring and a feedback loop with users can help quickly identify and address any issues that slip through pre-deployment testing. Monitoring APIs is a common way to ensure your system is up, performs well, and returns correct responses.
