What analysis technique involves executing the code and observing its behavior during execution?

Dynamic analysis is a technique used in software testing and security assessment that involves executing the code to observe its behavior during runtime. This approach allows testers to monitor various aspects of the application as it operates, such as resource usage, performance, and potential security vulnerabilities that may manifest while the software is in operation.

By running the code, dynamic analysis provides insights into how the application interacts with system resources and how it behaves under different conditions. This is especially useful for identifying runtime errors, memory leaks, and any unexpected behaviors that may not be apparent during static analysis, where code is examined without execution.

Furthermore, dynamic analysis can involve various testing methods, including unit testing, integration testing, and fuzz testing, which can provide a comprehensive understanding of the software’s functional and non-functional characteristics in real-time scenarios. This technique is particularly advantageous for finding security vulnerabilities that are difficult to detect through static methods, as it can reveal issues like buffer overflows or improper input handling that occur during execution.
