Cyber Security Fundamentals for Coding Interviews

Many software engineering candidates struggle when technical interviews shift to security, authentication, and secure system design. Knowing how to write clean code is only half the battle; modern development roles require a solid grasp of how to protect data and secure communication channels. This text-only course prepares you to articulate key security principles clearly and apply them to realistic coding and system architecture scenarios. You will transition from having a vague understanding of security terms to confidently explaining complex cryptographic workflows and defense mechanisms. Starting with foundational definitions, you will explore how modern applications protect data both at rest and in transit. What you'll learn: - Understand core security principles including confidentiality, integrity, availability, and the zero-trust model - Apply symmetric and asymmetric encryption techniques to secure application data - Explain how secure communication protocols like TLS/HTTPS establish trust and protect network traffic - Implement secure authentication patterns, token-based authorization, and modern secret management workflows - Analyze common security vulnerabilities, such as injection attacks and cross-site scripting, to write defensive code - Practice answering common security-related coding interview questions using clear, structured explanations The course begins with foundational security terminology and basic cryptographic concepts before moving into practical secure coding practices, network protocols, and mock interview scenarios. This structured approach ensures you build a strong conceptual framework before tackling design challenges. This course is designed for beginner to intermediate software developers, computer science students, and self-taught programmers preparing for technical interviews. No prior background in security or cryptography is required. Read through the concepts, study the code patterns, and walk into your next interview fully prepared to discuss security.
