Learning objectives:
  The goal of this course is to inform students about the basic principles of network and systems security and relevant protocols and standards. Students are learned to design and manage security technologies.
  Secure Communication on the L2 Layer. Certificates and Digital Signature. Attacks in Computer Networks. Security Protocols, their Analysis, Verification and Design. Application of Security Protocols. Security on the L3 Layer. IPsec and VPN. Security of Network Services. IDS and IPS Systems. Security of Wireless Networks. Security of Sensor Networks.
Knowledge and skills required for the course:
  • Basic skills of operation systems Unix, Windows
  • Ability to read study texts in English (standards, RFC documents).
  • The architecture of computer networks (ISO/OSI, TCP/IP).
  • Overview of link layer protocols and network layer protocols.
Learning outcomes and competencies:
  Student is able to configure secure communication between computers. They have an overview of authentication principles and secure network services and they are able to manage them: SSH, VPN, email services, etc. They have an overview of security technologies used in wireless and sensor networks. Students are able to design and implement secure communication. Students are able to read standards and use them for project implementation.
Why is the course taught:
  Complementing for IT graduates to understand the principles of computer network security, i.e. how the security mechanisms in computer networks work, how they are configured.
Syllabus of lectures:
  1. Introduction. Overview of computer security.
  2. Security of the L2 layer (802.1x, PAP, CHAP).
  3. Certificates. Digital signature (PKI, TKPI). Certification authority. Authentication and authorization in computer networks AAA.
  4. Attacks in computer networks.
  5. Security protocols, their analysis and verification.
  6. Design of security protocols and their application. Payment protocols.
  7. Security of L3 layer. IPsec and VPN.
  8. Security of network services. Secure transport (SSL, TLS). Security on the application layer.
  9. Firewalls. IDS and IPS systems.
  10. Security of wireless and mobile networks. WEP, WPA.
  11. Security of sensor networks. ZigBee.
  12. Security in practice.
  13. Modern trends of networks security. Course summary.
Syllabus of laboratory exercises:
  1. Practical analysis of security protocol.
  2. Practical implementation of secure communication.
  3. Administration of secure communication (SSH, stunel, pgp). Creation of VPN connections. Secure connections testing.
Syllabus - others, projects and individual work of students:
 Practical analysis of security protocol. Practical implementation and administration of secure communication.
