Which type of analysis involves manually inspecting source code to identify vulnerabilities in programming techniques?

The correct choice is static analysis. This method involves examining the source code without executing it, allowing analysts to identify potential vulnerabilities, security flaws, and coding issues directly within the codebase. By reviewing the code line by line, tools or manual inspections can uncover weak programming techniques, such as poor input validation or inadequate error handling. Static analysis is often automated through various tools that can provide insights quickly and can be integrated into the development process, encouraging secure coding practices from the outset.

Dynamic analysis, in contrast, involves examining the program while it is running to identify vulnerabilities based on the program's behavior during execution. Reverse engineering refers to the process of analyzing compiled code to understand its structure and functionality, often used in cases where the source code is not available. Side-channel analysis focuses on gathering information from the physical implementation of a system, rather than the code itself, by observing things like timing or power consumption patterns. Thus, static analysis stands out as the method specifically designed for reviewing source code for vulnerabilities.
