| Other | Reduce Maintainability 注記：This issue makes it more difficult to maintain the product, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. For example, if there are two copies of the same code, the programmer might fix a weakness in one copy while forgetting to fix the same weakness in another copy. |
潜在的な緩和策
Phases : ImplementationMerge common functionality into a single function and then call that function from across the entire code base.
検出方法
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.)脆弱性マッピングノート
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.
