Overview What You Will Learn Curriculum Instructor

Course Overview

Web application security is a critical aspect of modern development, especially with the rising threats targeting online platforms. Ruby on Rails, a widely adopted web framework, is not only known for its simplicity and speed but also its ability to support secure coding practices. Understanding and mitigating common vulnerabilities within Rails applications is vital for developers, as it ensures the safety of both user data and the integrity of the application itself. This course offers a practical approach to learning security concepts using real examples in Ruby on Rails, which can be applied across any development stack.

This course begins with an introduction to Ruby and Rails, setting the stage for security topics within the framework. Learners explore various injection attacks including SQL injection, XSS, and header manipulation. It then dives into CSRF and clickjacking, examining their mechanics and Rails-specific countermeasures. Other topics include configuring default headers, implementing content security policies (CSP), and advanced rate limiting using the Rack Attack gem. The course also covers secure file handling, virus scanning with Clamav, metadata filtering, and static analysis using Brakeman, culminating with actionable insights on testing and strengthening app security.

This chapter-based course equips developers to write safer, more resilient Rails applications with practical strategies and essential tools for secure coding.
