Course details

This course introduces students to the fundamentals of network security in a clear and practical way. It explains how modern communication networks work and why they are vulnerable to attacks such as hacking, data theft, malware, and denial-of-service attacks. Students will learn how attackers think, the common techniques they use, and how these attacks affect real-world systems like email, web services, online banking, and voice communication.The course covers key security concepts such as encryption, authentication, access control, firewalls, intrusion detection, and secure network protocols. Special emphasis is given to protecting sensitive information like passwords, personal data, and financial details. Along with theory, the course includes hands-on demonstration sessions where students can see security tools and attack–defense techniques in action. By the end of the course, students will have a strong foundation to understand, analyze, and secure computer networks in practical environments.
