Course detail

Projecting, Administration and Security of Computer Networks

FEKT-MPC-NSBAcad. year: 2023/2024

Modern civilization depends on a correct functioning of computer networks. Significant attention must therefore be paid to the security and design of these networks. On completing the course, students will have a thorough overview of the functioning, security and design of computer networks. Lectures are mainly dedicated to explaining the protocols in particular computer network layers, the principles of securing computer networks, and the design of computer networks. Laboratory exercises are dedicated to the administration and security of linux servers.

Entry knowledge

No special knowledge is required.

Rules for evaluation and completion of the course

20 points can be obtained for fulfilling the tasks in laboratory exercises and 80 points can be obtained for the examination. The examination is a written one and it is to check whether the student is able to explain the functioning and security of computer networks in different layers of the RM-OSI model.
Attendance at Laboratory exercises is obligatory.

Aims

The goal of the course is to provide students with a good insight into the branch of designing and securing computer networks and their functioning.
A student who completes the course will be able to:
• explain the applications of cryptography in computer networks,
• explain the way computer networks in the physical layer function and are secured,
• explain the way computer networks in the link layer function and are secured,
• explain the way computer networks in the network layer function and are secured,
• explain the way computer networks in the transport layer function and are secured,
• explain the way computer networks in the application layer function and are secured,
• explain the general methodology of computer network design,
• deal with the administration and security of linux servers.
