Semester 6 (Elective 4)

About the Course:

This course will present security aspects from a software life cycle process - requirement,

Architecture - Design, coding, and testing. Students will have opportunity well dwell in to technical "how to" with hands on sessions and some case studies.

Course Objectives:

  • Understand various cyber threats and attacks; learn about Secure Software development process.

  • Understand how privilege escalation attacks and Buffer overflows happen Learn to analyze malware and differentiate between categories such as Virus and Worms.

  • Understand the concept of Threat Modelling and its application.

  • Understand and learn about the most common Web application security vulnerabilities.

  • Understand and apply various security testing techniques and tools.

Course Outcomes:

At the end of this course, the student will be able to:

  • Be able to identify possible misuse cases in the context of software development.

  • Apply the different concepts and techniques learnt to prevent privilege escalation and Buffer overflow attacks. Apply the acquired knowledge to create a Worm from a Virus.

  • Apply Threat Modelling techniques to expose inherent/dormant vulnerabilities in a given software design /architecture and propose alternate solutions.

  • Be able to design and develop Secure Web applications.

  • Be able to perform Penetration testing on the given software system.
