Overview What You Will Learn Curriculum Instructor

Course Overview

C remains a foundational programming language widely used in system software, embedded systems, and performance-critical applications. However, its flexibility comes at the cost of security risks if not used properly. Learning secure programming practices in C is crucial for developers working in environments where performance and low-level system access are essential. This course equips learners with the skills to identify and mitigate common vulnerabilities associated with C, ensuring the development of robust and secure software.

This course begins with an introduction to the C programming environment, followed by best practices for writing secure code using libraries and proper structures. Learners build their first C application and explore the inherent weaknesses of the language. The course delves into critical topics such as memory allocation, buffer overflows, and return-oriented programming (ROP) attacks. It continues with format string vulnerabilities, secure use of variable types, and how to prevent integer overflows and underflows. It also covers pointer-related issues like null pointer dereference, use-after-free, and double-free errors. Finally, the course addresses secure input/output practices to avoid common file system vulnerabilities.

By the end, learners will understand C's core security pitfalls and how to avoid them to write safer, more secure applications.
