How to implement security testing in the software engineering process
Through the following, we will review a general model for implementing security tests in the software engineering process:
- Risk Analysis and Test Design : Analyze the potential risks of the software system and identify potential weak points and potential security vulnerabilities. Based on this analysis, design appropriate security tests to test for those weak points and security vulnerabilities.
- Authentication and Authorization Testing: Perform tests to ensure that authentication and authorization are working properly, validate login and authorization processes, process permissions, test user identity confirmation, and log activities.
- Test for invalid entries: Perform tests to verify how the system handles invalid or suspicious entries and enter incorrect or unexpected data and verify the system's response and ensure that it handles them securely without exposing security vulnerabilities.
- Penetration Testing : Perform tests to test the strength and resistance of the software system to penetration. These tests can include ethical penetration tests, simulated penetration attacks, and hit tests. These tests aim to discover potential security vulnerabilities and fix them before they are exploited by real attackers.
- Fraud Protection Testing : Run tests to verify how the system handles potential fraud attempts. Test known and suspected fraud attacks and verify the system's ability to detect, prevent and log them.
- Denial of Service Attack Testing : Perform tests to assess the system's ability to handle Denial of Service attacks, experiment with a high load of requests and attempt to flood the system, and verify that the system responds appropriately and is able to resist such attacks.
- Encryption and Security Testing : Perform tests to verify that the encryption and security mechanisms used in the system are working properly, verify that appropriate encryption protocols are used, and verify that data sent and stored is properly encrypted and protected from unauthorized access.
- Update testing and bug management : Perform tests to verify how the system handles update processes and manages known security bugs. Verify that the system is able to download and install security updates on a regular basis and that bugs are managed effectively and fixed in a timely manner.
- Test rules and policies : Perform tests to verify that the system adheres to applicable security rules and policies and verify that appropriate rules are applied for each aspect of security, such as password, approval, storage, and access rules.
- Review guidelines and instructions : Review the security guidelines and instructions used in the software engineering process and ensure that they are reliable and up-to-date. These guidelines should outline the steps required to implement security and the recommended security practices for the development team.
These steps should be performed frequently and regularly throughout the software engineering process to ensure that the software system is well protected and responsive to potential security threats.
