Foundations of Application Security for Developers and DevOps

In today's digital landscape, securing software is just as important as writing functional code. Developers and DevOps professionals must proactively defend their systems against evolving security threats and data breaches. This text-based course guides you through the core principles of application security (AppSec) and DevSecOps. You will start with essential security terminology, common vulnerability frameworks, and foundational concepts before moving on to practical strategies for writing secure code and monitoring system health. What you'll learn: - Understand fundamental security concepts, the modern threat landscape, and zero-trust principles - Identify and mitigate common application vulnerabilities like injection attacks and broken authentication - Apply secure coding best practices to prevent data breaches, leaks, and unauthorized access - Implement modern observability and continuous monitoring to track system health and detect anomalies - Evaluate software supply chain security, including dependencies and third-party libraries - Integrate security checks seamlessly into the software development lifecycle and DevOps pipelines The journey begins with foundational security definitions and threat modeling concepts. From there, you will read through real-world scenarios, analyze code examples, and learn how to configure automated security checks and monitoring systems to keep your applications resilient. This course is designed for beginner developers, aspiring DevOps engineers, and system administrators who want to build a security-first mindset. No prior experience in cybersecurity is required.
