Almost all software is under attack today, and many organizations are unprepared in their defense. This professional certificate program, developed by the Open Source Security Foundation (OpenSSF), a project of the Linux Foundation, is geared towards software developers, DevOps professionals, software engineers, web application developers, and others interested in learning how to develop secure software, focusing on practical steps that can be taken, even with limited resources to improve information security. The program enables software developers to create and maintain systems that are much harder to successfully attack, reduce the damage when attacks are successful, and speed the response so that any latent vulnerabilities can be rapidly repaired. The best practices covered in the course apply to all software developers, and it includes information especially useful to those who use or develop open source software. The program discusses risks and requirements, design principles, and evaluating code (such as packages) for reuse. It then focuses on key implementation issues: input validation (such as why allowlists and not denylists should be used), processing data securely, calling out to other programs, sending output, cryptography, error handling, and incident response. This is followed by a discussion on various kinds of verification issues, including tests, including security testing and penetration testing, and security tools. It ends with a discussion on deployment and handling vulnerability reports. The training courses included in this program focus on practical steps that you (as a developer) can take to counter most common kinds of attacks. It does not focus on how to attack systems, how attacks work, or longer-term research. Modern software development depends on open source software, with open source now being pervasive in data centers, consumer devices, and services. It is important that those responsible for cybersecurity are able to understand and verify the security of the open source chain of contributors and dependencies. Thanks to the involvement of OpenSFF, a cross-industry collaboration that brings together leaders to improve the security of open source software by building a broader community, targeted initiatives, and best practices, this program provides specific tips on how to use and develop open source securely.
