System Design Security: Mitigating Common Threats and Vulnerabilities

Designing scalable software is only half the battle; ensuring your architecture can withstand modern security threats is critical to protecting user data and maintaining system integrity. In this comprehensive text-based course, you will transition from a basic understanding of system architecture to designing secure, resilient systems. You will learn how to identify architectural vulnerabilities early in the design phase and apply industry-standard patterns to neutralize threats before they can be exploited. What you'll learn: - Understand foundational security principles, including the CIA triad and basic threat modeling. - Mitigate common attack vectors such as injection attacks, cross-site scripting, and Man-in-the-Middle (MITM) exploits. - Defend against Distributed Denial of Service (DDoS) attacks using rate limiting, web application firewalls, and CDN caching. - Implement modern authentication and authorization flows, including secure token management and API gateway security. - Apply zero-trust architecture concepts to secure communication between microservices. - Practice identifying system design flaws through realistic, written architectural scenarios. This course begins with essential security definitions and threat modeling frameworks before guiding you through step-by-step written analyses of classic vulnerabilities and modern mitigation strategies. You will study architectural patterns that keep data secure both at rest and in transit. This course is designed for beginner software engineers, aspiring system architects, and developers who want to build a solid foundation in security principles. No prior security experience is required. Start building secure-by-design systems today.
