In the year 2019, the PCI Security Standards Council released the PCI Software Security Framework (SSF) for ensuring a secure design and development of payment software. The PCI SSF is a new standard rolled out with the purpose to secure payment application software. This is a crucial move towards improving the security of payment applications and ensuring reliable online payment transactions. With this new framework in place, it can support the security requirements of both modern and traditional payment software. The SSF provides vendors a comprehensive security standard for building and maintaining payment software that protects payment transactions. It also helps secure against data vulnerabilities and sets a strong defense against attacks. PCI SSF is a methodology that facilitates robust security development practices in the industry. The PCI Security Standard Framework consists of two different and independent programs each of which has its own standard requirements, validation criteria, and SSC listing. The two programs include the Secure Software Lifecycle Program (SSL) and Secure Software Standard (SSS). Vendors will have to evaluate and determine which standards are applicable to them and accordingly comply with either of two PCI SSF programs.
