Automated Static Analysis
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)有効性 : High

理由 : This entry is primarily a quality issue with no direct security implications.コメント : Look for weaknesses that are focused specifically on insecure behaviors that have more direct security implications.
ノート
While the interpretation of "large number of children" may vary for each product or developer, CISQ recommends a default maximum of 10 child classes. [REF-1133]参考文献
