Performance of Gosec
Gosec, a tool for analyzing Go source code for security vulnerabilities, has several performance aspects to consider:Execution Time
For large codebases, Gosec can be relatively slow. For instance, in a case involving a large repository with about 80,000 lines of generated GraphQL server code, the execution time was significantly longer. The analysis took around 1.05 seconds for the `gosec` analyzer alone, but the overall process, including other linters, took approximately 6-7 minutes.Resource Usage
Running Gosec on large codebases can consume considerable memory. In one example, the memory usage averaged around 461.6 MB, with a maximum of 467.7 MB.Accuracy of Gosec
Gosec is generally effective in identifying security issues in Go code, but it also has some limitations:Issue Classification
Gosec categorizes issues based on their severity (LOW, MEDIUM, HIGH) and confidence level (how likely the issue is real). This helps in prioritizing the most critical vulnerabilities. However, it can make mistakes, and the confidence level indicates the likelihood of the issue being a false positive.Type of Issues Detected
Gosec can identify a wide range of security issues, including hardcoded credentials, weak cryptography, memory aliasing, unhandled errors, and more. It also reports non-compiling code, which can be useful for catching errors early.False Positives
While Gosec is effective, it can generate false positives. Users need to review the issues carefully, as many can be minor or safely ignored via comments.Limitations and Areas for Improvement
Edge Cases
Like other security tools, Gosec may have edge cases where it fails to identify certain issues or describes them differently. This can be particularly challenging if the codebase is complex or if the analysts cannot easily build the code and its dependencies.Customization and Specificity
For more in-depth analysis of specific types of issues, users might need to use more specialized tools or develop custom tooling. Gosec provides a broad range of checks but may not cover every niche scenario.Integration with CI Pipelines
While Gosec is valuable, its integration into CI pipelines can highlight areas that need improvement, such as the lack of a SECURITY.md file explaining how to report vulnerabilities or the absence of other SAST tools. In summary, Gosec is a valuable tool for identifying security vulnerabilities in Go code, but it requires careful review of its output to manage false positives and may need additional tools for more specialized analyses. Its performance can be slow on large codebases, and it consumes significant resources. Gosec - Pricing and Plans
