Introduction

The aim of the course is to make students aware of the security problems of information systems and networks, their mechanisms and technologies of protection, and to understand the parameters that make these protection mechanisms effective in modern systems. Firstly, the basic principles of cryptography are presented, then a number of important applications and practical techniques, and finally cryptographic policy and security management. The lesson includes both theory and hands-on sessions.

Some of the topics we will cover in class:

  • Cryptographic Algorithms & Tools
  • User Authentication
  • Access Control
  • Network Basics & Database Security
  • Malicious Software
  • Denial of Service (DoS) Attacks
  • Intrusion Detection Systems
  • Firewalls
  • Buffer Overflow
  • Software Vulnerabilities
  • Operating System Security
  • Internet Security Protocols



Grading

The final grade is calculated as follows:

  • 30% Programming Assignments (1:10%, 2:20%, 3:10% (bonus) - stands for both 2nd and 3rd exam)

  • 70% Final Exam All exams are given with closed books. During exams you are not allowed to use any kind of notes, books, and communication devices (i.e., mobile phones, tablets, laptops).
