+description: Snyk Security At Inception
+---
+
+# Project security best practices
+
+- Always run snyk_code_scan tool for new first party code that is generated in a Snyk-supported language.
+- If any security issues are found based on newly introduced or modified code or dependencies, attempt to fix the issues using the results context from Snyk.
+- Rescan the code after fixing the issues to ensure that the issues were fixed and that there are no newly introduced issues.
+- Repeat this process until no new issues are found.
