Student are 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 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.

The goal of this course is to inform students about basic principles of network and systems security and relevant protocols and standards. Students are learned to design and manage security technologies.

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.
