Description
In today's digital world, the protection of information is more critical than ever. Cryptography and Computer Security is a comprehensive course designed to equip learners with the foundational knowledge and practical skills needed to secure data and defend against cyber threats.This course begins with the principles of cryptography, exploring symmetric and asymmetric encryption, cryptographic hashing, digital signatures, and key exchange protocols. You'll learn how these tools work, how they are applied in real-world systems, and the mathematics that underpins their security.Moving beyond theory, the course covers core concepts in computer and network security, including secure communication protocols (SSL/TLS, IPsec), authentication mechanisms, firewalls, intrusion detection systems, and common attack vectors like phishing, DDoS, and man-in-the-middle attacks. Through hands-on exercises and case studies, you'll gain practical experience in identifying vulnerabilities and implementing secure solutions.By the end of the course, you will be able to analyze cryptographic algorithms, apply encryption techniques, evaluate security protocols, and propose effective defenses against cyber threats. Whether you're aiming for a career in cybersecurity, software development, or IT infrastructure, this course lays a strong foundation in both cryptographic theory and applied network security.No prior experience in cryptography is required, but a basic understanding of programming, computer networks, and mathematical reasoning will help you succeed.
