Course Introduction
Information Security is a comprehensive course that introduces students to the principles and practices used to protect digital information and systems from unauthorized access, misuse, or destruction. The course covers foundational topics such as cryptography, network security, access control, authentication, security policies, and risk management. Students will also explore real-world security challenges, including malware, social engineering, and vulnerabilities in software and hardware. Through lectures, hands-on labs, and case studies, students gain the skills necessary to identify potential threats, implement security measures, and respond effectively to security incidents in various organizational contexts.
