Which coding standard is widely adopted to promote security?

The choice of OWASP Secure Coding Practices as a widely adopted coding standard to promote security is particularly pertinent because it offers a comprehensive framework designed specifically to address security vulnerabilities in software development. OWASP, which stands for the Open Web Application Security Project, focuses on improving the security of software through best practices and guidelines that help developers identify and mitigate security risks early in the development lifecycle.

By following OWASP's recommendations, developers are better equipped to understand the common security threats that web applications face, such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). These guidelines encourage developers to incorporate security into their coding practices from the outset, enhancing the overall security posture of the applications being developed.

In contrast, ISO 9001 primarily focuses on quality management systems and does not directly address security in software development. W3C Standards are geared towards web technology standards, influencing interoperability and usability rather than security, while CMMI (Capability Maturity Model Integration) is a process improvement framework that can enhance software development practices but does not specifically center on security. Thus, OWASP Secure Coding Practices stands out as the most relevant and effective choice for promoting security in coding standards.
