Application security policy

An application security policy is a formal document that defines an organization's rules, standards, and procedures for protecting its software applications throughout their entire lifecycle — from design and development to deployment, maintenance, and retirement. It establishes mandatory security requirements such as secure coding practices, data handling protocols, authentication and authorization mechanisms, vulnerability management processes, and acceptable risk thresholds.

As a foundational element of application and software security, this policy assigns responsibilities to stakeholders across the organization and provides clear guidelines for security testing, incident response, and regular audits. By embedding security controls directly into the software development lifecycle (SDLC), an application security policy ensures that threats are proactively mitigated, vulnerabilities are systematically addressed, and security best practices are consistently applied — ultimately safeguarding sensitive data and maintaining the integrity and availability of critical business systems.
