Cyber Security

The course has been designed to give students an extensive overview of cyber security issues, tools and techniques that are critical in solving problems in cyber security domains. The course aims at providing students with concepts of computer security, cryptography, digital money, secure protocols, detection and other security techniques. The course will help students to gauge understanding in essential techniques in protecting Information Systems, IT infrastructure, analysing and monitoring potential threats and attacks, devising security architecture and implementing security solutions. The students will also have a wider perspective to information security from national security perspective from both technology and legal perspective.

Program Overview

Learning Outcomes

  • Understand, appreciate, employ, design and implement appropriate security technologies and policies to protect computers and digital information.
  • Identify & Evaluate Information Security threats and vulnerabilities in Information Systems and apply security measures to real time scenarios
  • Identify common trade-offs and compromises that are made in the design and development process of Information Systems
  • Demonstrate the use of standards and cyber laws to enhance information security in the development process and infrastructure protection
