Course detail

Projecting, Administration and Security of Computer Networks

FEKT-MPC-NSBAcad. year: 2022/2023

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.
