Software systems can be validated as conforming to the CERT Oracle Secure Coding Standard for Java. Source code analysis tools, including compilers and static analysis tools, can be certified as able to validate source code as conforming to this coding standard.
...
Although uncommon, some guidelines are entirely non-normative. The following guidelines, for example, are entirely non-normative:
- NUM52-J. Be aware of numeric promotion behavior
- EXP55-JGJ. Use the same type for the second and third operands in conditional expressions
Source Code Conformance
Conformance to The CERT Oracle Secure Coding Standard for Java can be used as as security indicator or metric. While conformance does not guarantee the absence of vulnerabilities (for example, vulnerabilities resulting from design flaws), it does guarantee the absence of coding errors that are commonly found to be the root causes of vulnerabilities.
...
Guidelines in this standard are classified into three levels (see Rec.: Priority and Levels). Emphasis should be placed on conformance Level 1 (L1) guidelines. Software systems that have been validated as complying with all Level 1 guidelines are considered to be L1 Conforming. Software systems can be assessed as L1, L2, or fully conforming depending on the set of guideline to which the system has been validated.
