Original Post: Write custom rules with the new Playground
Overview
Organizations have unique security challenges influenced by their security tolerance, technical infrastructure, and valuable data. Effective use of Source Code Analysis Tools (SAST tools) is crucial, and Semgrep provides a powerful solution through custom rules tailored to an organization’s specific needs.
Custom Rules in Practice
Custom rules in Semgrep can enforce internal sanitization functions, ban vulnerable functions, prioritize rules, and reduce false positives. These rules help catch vulnerabilities, prevent new ones, and significantly reduce noise, saving considerable time. Examples demonstrate major security incidents being averted using custom rules.
New Playground
Semgrep’s Playground is an ideal space to write, test, and refine custom rules. Recent enhancements allow users to write a rule in under 10 minutes, using resources like the Registry and pattern syntax documentation. Users can share rules privately or publicly and start monitoring their code bases through the Rule Board.
Conclusion
The Playground aims to make rule-writing straightforward and efficient. Users are encouraged to try it out and join the Community Slack for additional support.
