Subject aims expressed by acquired skills and competences

The course is divided into several blocks, which are thematically focused on the following areas: theoretical introduction, which will explain the basic concepts and vocabulary of cyber security, the comparison of operating systems and explanation of the way how to exploit mistakes in such systems, a description of the behavior of specific attacks and their modifications (course focuses on 2 specific types of attacks- ransomware and denial of Service), creatinon of a network of Internet robots (botnet) and defence against attacks from these networks, the method for analyzing the behavior and structure of the virus, explaining the process of developing the virus and the antivirus, recommended user behavior when using the internet, which will be supplemented by real world use cases, forensic techniques.

Teaching methods



The course will cover a wider range of defense techniques and attacks on computer systems. There will be mentioned both historically classic techniques and modern processes and algorithms. The course will include targeted (hacking) and spyware attacks, botnets, and so on. Part of the course will also be the basics of digital forensic analysis and penetration testing. After completing the course, the student should have a thorough knowledge of the above-mentioned areas, including the possibility of applying countermeasures and enhancing the security of computer systems. Part of the course will include separate assignments from lectures (or exercises). Their review and presentation will be part of lectures. Course will include individual assignments (presentations or projects). Their review and presentation will be part of lectures.

Way of continuous check of knowledge in the course of semester

Kontrola je založena na vypracovávání protokolů předmětu, pomocí kterých student prokazuje nejen pochopení informací z přednášek, ale i schopnost jejich implementace v daném programovém prostředí. K získání zápočtu je nutno odevzdat cvičícímu všechny požadované protokoly a mít alespoň 80% fyzické účasti na laboratořích. Zápočet je podmínkou NUTNOU k připuštění ke zkoušce.


Další požadavky na studenta

It is required the ability to create programs in arbitrary programming language and apply lecture knowledge into algorithms. Additional requirements are not defined.


Subject has no prerequisities.

Subject syllabus:

Lectures: 1. Introduction 2. Comparison of operating systems and well-known vulnerabilities 3. Types of cyber attacks 4. Evolution of ransomware and defense against ransomware attacks (CryptoLocker, CryptoWall, CTB Locker, etc.) 5. Botnets and denial of service attacks (DOS, DDOS) 6. Analysis of virus source code, debugging methods and tools 7. Basic techniques for reducing the chances of virus detection 8. Antivirus and immunization methods 9. Abusing software bugs 10. Software penetration testing 11. User identity, analysis of behavior and social networks analysis 12. Forensic techniques 1: analyze seized equipment 13. Forensic techniques 2: reconstruction of user activities on seized equipment Laboratories: 1. File inclusion: Introducing web attacks and getting familiar with the DVWA application that we will use in the next few exercises. 2. SQL Injection: Students will extract user passwords from database alongside with another useful information such as DB structure, name and version. 3. Password cracking: Cracking passwords using a brute force or dictionary attack algorithms. 4. XSS and Session hijacking: Exercise showing an interesting web attack - stealing a foreign session. Try to steal a session of a user who visits a guestbook page in the DVWA application. 5. Drive-by download: Combination of malicious code delivery and its activation through JavaScript. Windows script host usage and possibilities of remote communication and access to the power shell from JavaScript. 6. Denial of service: Students will perform denial of service attack on the prepared web servers. Wireshark network analysis tool will be used to compare legitimate and malicious traffic. 7. Google hacking: Introduction to information gathering using available tools such as google search engine. 8. Hacking: Practical test of simple hacking. Learn basic hacking techniques using the www.hackthissite.org project. 9. Exploitation, Metasploit framework: Vulnerability exploitation using Metasploit framework. Use the Metasploit framework to prepare the attack environment to allow the attacker to exploit through vulnerability in Adobe Flash Player. 10. Penetration testing: A final exercise where students recapitulate the acquired knowledge. A fictitious company asked you to perform a security audit or penetration testing. On a theoretical level, simulate and write down the procedures and tools used. 11. Student presentations Course will include individual assignments (presentations or projects). Their review and presentation will be part of lectures.
