Foundations of Application Security: Identifying Common Threats

In today's digital landscape, securing software is a fundamental skill for every developer and IT professional. Understanding how attackers exploit software vulnerabilities is the first step toward building resilient, secure systems. This text-based course guides you through the core principles of application security, helping you move from a basic understanding of software to a security-first mindset. You will learn to think like an attacker to identify weaknesses in code, APIs, and authentication mechanisms before they can be exploited in the wild. In this course, you will: 1. Understand fundamental security concepts, terminology, and the modern threat landscape. 2. Identify critical vulnerabilities using the widely recognized OWASP Top 10 framework. 3. Recognize weaknesses in modern authentication, authorization, and API design. 4. Analyze how common attacks like SQL injection and cross-site scripting (XSS) occur. 5. Apply secure coding principles and basic threat modeling techniques to your projects. 6. Integrate fundamental security checks into modern software development workflows. Starting with essential security definitions and concepts, this course progresses to real-world threat scenarios and mitigation strategies, complete with written code examples and analysis. It is designed for beginner developers, QA engineers, and IT professionals, requiring no prior cybersecurity experience. Start reading today to build a strong foundation in application security and write safer code.
