How do you perform web security testing on a web application that uses a microservices architecture? (2024)

Key takeaways from this article

• Map and understand your architecture:

  Before diving into testing, get a lay of the land. Use tools to identify components and data flows. This knowledge is power—it enables you to pinpoint where to focus your security efforts.

• Threat modeling with STRIDE:

  Assessing each microservice individually for risks helps prioritize threats. By identifying where you're most vulnerable, you can direct resources efficiently, fortifying your defenses where they're needed most.

  The initial phase of web security testing involves delineating the scope and boundaries of the web application and its microservices. This entails mapping out system components, interfaces, data flows, and user roles. Tools like Nmap, Burp Suite, or OWASP ZAP aid in scanning and identifying endpoints, ports, and services. Additionally, reviewing documentation, source code, and configuration files provides insights into functionality, logic, and dependencies. Establishing clear scope parameters ensures comprehensive security assessment and effective risk mitigation.

  Antes de comenzar las pruebas de seguridad en una aplicación de microservicios, es importante comprender el alcance de la aplicación y los límites de los microservicios involucrados. Esto implica identificar todas las funcionalidades, interfaces y puntos de entrada de cada microservicio, así como los posibles puntos de integración y comunicación entre ellos. También es importante establecer los límites de las pruebas para garantizar una cobertura adecuada.

  Evaluate potential security threats to each microservice, considering aspects like data sensitivity, exposure points, and authentication mechanisms. Use threat modeling techniques such as STRIDE to systematically identify security risks associated with spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of privilege.Considering an e-commerce platform, assess risks like unauthorized access to user data through the authentication service or payment fraud via the payment processing service. Identify potential threats such as SQL injection in the product catalog service or XSS (Cross-Site Scripting) attacks targeting user sessions.

  Una vez que se comprende el alcance de la aplicación, es necesario evaluar los riesgos y amenazas potenciales que podrían afectar la seguridad de los microservicios. Esto implica identificar vulnerabilidades conocidas, como inyecciones de SQL, ataques de denegación de servicio (DoS), vulnerabilidades de autenticación y autorización, entre otros. También se deben considerar los posibles riesgos asociados con la comunicación entre microservicios y la gestión de datos sensibles.

  Third and most important step is testing and simulating attacks.You need to make sure these work correctly:1. Authentication and Authorization.2. Data Encryption.3. Session Management.4. Error Handling.5. Network Security.To avoid these Types of Attacks:- Fuzzing: Input random data into the application to find security vulnerabilities and crashes.- Injection Attacks: Test for SQL and command injection.- Security Control Bypass: Try to bypass authentication, authorization, and other security mechanisms to gain unauthorized access to data and resources.

  To maintain strong security, it’s crucial to make testing a continuous process. Regularly repeat the security tests to catch new vulnerabilities as they arise. Automate as much of the process as possible using tools and scripts, so you can run these tests frequently without manual effort. Automation helps ensure that your system is always protected, even as it evolves, by quickly identifying and addressing potential threats before they become serious issues. This ongoing cycle of testing, fixing, and retesting keeps your system secure and resilient over time.
