First Steps for DevSecOps: Continuous Code Quality and Security Management Using Sonarqube

DevSecOps is a methodology that integrates Development, Security, and Operations to consider security from the early stages of development. While the existing development approach was a relay race proceeding stage by stage, DevSecOps aims for a structure in which the three teams collaborate to detect and respond to mistakes early.

The key elements for implementing this are automation and security integration, continuous monitoring, and a change in development culture. Kakaopay integrates security by automatically performing static analysis and vulnerability analysis on every code change through its deployment control pipeline.

Sonarqube is used as a static code analysis tool in this DevSecOps environment to automatically detect bugs, code smells, security vulnerabilities, and code duplication and complexity. Through this, developers can manage technical debt and focus on more important tasks.

In particular, Kakaopay actively utilizes Sonarqube Custom Rule. Based on cases of past incidents, it creates custom rules to prevent the same issues from recurring, and applies optimized security and quality standards suited to the nature of each team's project.
