Tutor:

Simona Fornůsek, Tomáš Zahradnický

Supervisor:

Department of Information Security

Synopsis:

The students will gain theoretical and practical knowledge and experience in the area of current security threats in computer networks, specifically about detection and defense. The course explains basic pricipals of security monitoring, packet-based and flow-based analysis, in order to detect anomalies and suspicious network traffic. The course focuses on explanation and practical examples of various mechanisms of securing network infrastructure and detection in real time. The course covers general principals of handling detected security events (i.e. incident handling and incident response).

Requirements:

General knowledge about the functioning of computer networks and systems. Basics from programming.

Syllabus of lectures:

1. Introduction, Selected Network Protocols and Their Security Weaknesses

2. Network attacks 1 (Introduction)

3. Network attacks 2 ((D)DoS, Scanning, Brute-Force)

4. Network attacks 3 (Covert Channels, MitM, Poisoning, L7 threats)

5. Remote Access

6. Active Defense, Cyber Deception

7. Data mining

8. Statistical methodology for anomaly detection

9. Intrusion Detection Systems

10. Incident response

11. Penetration testing

12. Reserved (Social Engineering)

Syllabus of tutorials:

1. ARP Man-in-the-Middle (MitM) and Scapy

2. (Distributed) Denial of Service

3. Packet-Based Network Analysis

4. Flow-Based Network Analysis

5. Network Scanning and Vulnerability testing

Study Objective:

The goal of the course is to teach the students basic security aspects of communication protocols in wired, optical, and wireless networks. Emphasis is put on detection and prevention of attacks on resources and information systems in wired computer networks.
