Best Practices for Application Security

This chapter explores essential best practices in application security, focusing on embedding security into every phase of the Secure Software Development Lifecycle (SDLC) to protect supply chain applications. Key areas include secure coding, rigorous testing, and threat modeling, along with case studies such as the SolarWinds breach to illustrate the importance of proactive security. By integrating practices like threat modeling, secure code review, and automated testing tools (e.g., SAST, DAST, OWASP Threat Dragon), the chapter underscores the need for a fortified software supply chain against evolving cyber threats.
