Course objectives
The lecture deals with methods and tools for security analysis of network traffic. Mathematical and visualisation methods processing aggregated characteristics of TCP/IP data are introduced as well as simple but useful methods. Apart from traffic volume quantities, the primary focus will be on IP traffic flows with emphasis on network security. We are aimed at high-speed networks. The studied methods will be illustrated on traffic samples from the Masaryk university network.
At the end of the course student should be able to:
understand the structure of data on local network and its edge;
understand basic methods for analysis of traffic and use relevant tools;
Syllabus
  • Fundamentals of TCP/IP communication and application protocols.
  • Network attacks and network layers. Network security devices: IDS/IPS, antispam filter, antivirus.
  • Basics of network monitoring: packets, IP data flows, measurement methods, tools for their analysis and visualisation.
  • Simple and advanced methods proccessing IP flow data. Traffic volume quantities, time-series analysis, prediction methods. Distribution of key items of IP flows (addresses and ports) in traffic samples: entropy and principal component analysis. Overview of available implementations.
