CompTIA CASP+ Practice Test

Which testing methods should be implemented in the SDLC for ASICs used in an IDS to ensure code integrity?

1. Black box testing by the manufacturer

2. White box unit testing and black box testing

3. Integrated testing by the development and security teams

4. End-to-end testing after deployment

The correct answer is: White box unit testing and black box testing

The implementation of both white box unit testing and black box testing in the Software Development Life Cycle (SDLC) for Application-Specific Integrated Circuits (ASICs) used in Intrusion Detection Systems (IDS) is a robust approach to ensure code integrity. White box unit testing allows developers to examine the internal workings of the ASIC code. This testing method is advantageous because it enables the identification of vulnerabilities, logic errors, and unexpected behavior early in the development process. Through this level of scrutiny, developers can ensure that the code is optimized, efficient, and aligned with security protocols. Complementing this, black box testing is essential as it assesses the functionality of the ASIC without any knowledge of its internal structure. This form of testing simulates real-world scenarios and user interactions, enabling testers to validate that the ASIC behaves as expected from an end-user perspective, further confirming its integrity and security measures. Combining these two testing methodologies comprehensively evaluates both internal code integrity and external functionality, which is crucial for ensuring that the ASIC can effectively operate as part of an IDS without introducing flaws that could be exploited. Other approaches, such as integrated testing by development and security teams, while valuable, may not be as thorough by themselves as they often rely on existing test strategies and
