A source code analysis tool is augmented to support rule-based analysis of code to attempt to identify certain lexical information indicative of hard-coded secret (e.g., password) support in the code. The tool takes the source code as input, parses the content with a lexical analyzer based on language grammar, and processes the resulting data through preferably a pair of rule-based engines. Preferably, one engine is configured to identify variables explicitly intended to be used as a hard-coded secret, and the other engine is configured to identify data strings that could potentially support such a secret. The outputs of these rules engines are consolidated and evaluated to identify a likelihood that the code under examination includes support for a hard-coded secret. The result is then provided to the developer for further action to address any potential security vulnerability identified by the analysis.
