This coding standard consists of rules and recommendations. Rules are meant to provide normative requirements for code; recommendations are meant to provide guidance that, when followed, should improve the safety, reliability, and security of software systems. However, a violation of a recommendation does not necessarily indicate the presence of a defect in the code. Rules and recommendations are collectively referred to as guidelines.
Rules
Rules must meet the following criteria:
- Violation of the guideline is likely to result in a defect that may adversely affect the safety, reliability, or security of a system, for example, by introducing a security flaw that may result in an exploitable vulnerability.
- The guideline does not rely on source code annotations or assumptions.
- Conformance to the guideline can be determined through automated analysis (either static or dynamic), formal methods, or manual inspection techniques.
Recommendations
Recommendations are suggestions for improving code quality. Guidelines are defined to be recommendations when all of the following conditions are met:
