Secure Software Development

Implementation

David A. Wheeler

Modern software is under constant attack, but many software developers have never been told how to effectively counter those attacks. This course works to solve that problem, by explaining the fundamentals of developing secure software. Geared towards software developers, DevOps professionals, software engineers, web application developers, and others interested in learning how to develop secure software, this course focuses on practical steps that can be taken, even with limited resources to improve information security. This course will enable 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.

This course focuses on key implementation issues: input validation (such as why allowlists should be used and not denylists), processing data securely, calling out to other programs, sending output, and error handling. It focuses on practical steps that you (as a developer) can take to counter the most common kinds of attacks.

This is the second of the three courses in the Secure Software Development Fundamentals Professional Certificate program, and was developed by the Open Source Security Foundation (OpenSSF), a project of the Linux Foundation focused on securing the open source ecosystem.

Reviews summary

Practical secure software development

According to learners, this course offers a largely positive experience, providing practical implementation skills for secure software development. Students highlight the clear explanations of key concepts such as input validation, secure data processing, and error handling. It is widely regarded as offering essential foundational knowledge, making it highly relevant for professionals aiming to enhance their coding security. While most beneficial for those with some prior programming experience, some reviews indicate it might be less comprehensive for very advanced learners seeking deep dives into niche topics.

Provides strong basics, but not deep advanced topics.

"This course is a solid introduction to secure coding best practices."

"It lays a great foundation, but don't expect deep dives into every vulnerability type."

"For me, it covered the fundamentals well, though I wish there were more advanced examples."

Best for those with some programming background.

"It's definitely geared towards developers who already have some coding experience."

"As a software engineer, I found the pace and content perfectly suited for my background."

"Beginners without prior programming might find some parts challenging."

Strong emphasis on secure input handling.

"The chapters on input validation and allowlisting were particularly insightful and useful."

"I learned so much about proper input sanitization and why it's critical for security."

"The details on avoiding denylists for input validation were a key takeaway for me."
