Closing coverage gaps in application security is an ongoing process that requires understanding the application landscape, defining security policies, implementing policy builders, tracking security controls, addressing coverage gaps, integrating with application security testing (AST), and monitoring and improving. Application Security Posture Management (ASPM) tools like Snyk AppRisk can support these efforts by providing a comprehensive shared view of software assets, enabling contextual enforcement of AppSec policies and controls, automating policy creation and monitoring existing controls, prioritizing business-critical areas for remediation, integrating with AST, and continuously monitoring and improving security measures.
