Security of systems and networks

  • Course name: Security of systems and networks (SSN)
  • Course number: SNE-08


Course characteristics

Key concepts of the class

  • Applied cryptography
  • Security protocols
  • Network and Internet security
  • Authentication and Authorization
  • Software Security

What is the purpose of this course?

This course will cover the fundamentals of security, security protocols, and their applications in real-world. The topics covered in this course include applied cryptography, authentication, passwords, practical security, social aspects of security, SSL/TLS, email security, PKI, and IPSec. Furthermore, this course will strengthen the security knowledge of the students and guide them in the right direction for their upcoming research projects and advanced courses. The course is divided into two parts. The first part will cover the theory and hands-on practice of the concepts taught at class. And the second part of the course will focus on the course projects. The student will work on a security project by using the concepts taught in the class.


Prerequisites

  • No specific prerequisites are mandated.

Recommendations for students on how to succeed in the course

References:

  • Attend the lectures
  • Read the lecture notes
  • Read the related chapters in the book


  • Attend and finish the labs


  • Finish your assigned project successfully

Course Objectives Based on Bloom’s Taxonomy

What should a student remember at the end of the course?

By the end of the course, the students should be able to:

  • Demonstrate the acquired knowledge and skills in applied cryptography (symmetric and asymmetric cryptography),
  • Operate classical enigma machine, encode and decode messages with it
  • Demonstrate the working knowledge of famous cryptographic algorithms and discuss their shortcomings
  • Demonstrate and operate the already implemented security protocols over internet,
  • Reason about the problems in the security of networked systems and current internet and their existing solutions,
  • Solve mathematical problems (especially in number theory),

What should a student be able to apply at the end of the course?

By the end of the course, the students should be able to apply:

  • Crypt-analyze ciphertext and decrypt through frequency analysis and other important techniques
  • Design security protocols
  • Find security flaws in security protocols
  • Get hands-on experience of the existing enterprise cryptographic algorithms and use them in projects,
  • Demonstrate the skill of finding out security issues in networked systems and internet technologies,

Course evaluation

The acquired knowledge will be evaluated via labs, a project, and the exam, with points as in the following table:

Type of Evaluation Points
