Course guarantor:

Miroslav Minárik

Lecturer:

Miroslav Minárik

Tutor:

Miroslav Minárik

Supervisor:

Department of Mathematics

Synopsis:

Understanding the history and present network (LAN, WAN, use the principles and technologies). Architecture of reference model ISO/OSI. Network protocols, practical exercises with TCP/IP communications. Internet services - mail, remote access, www. Secure communication, tunneling.

Directory services, certificates, certification authorities, public key infrastructure (PKI). Use in practice. Network security - firewalls (packet filters, proxies, gateways, NAT, DMZ), practical exercises.

(According to the interest - the serial control lines, modems)

Requirements:

Programming basics and Algorithmization (in the extent of the courses ZPRO, ZALG held at the FNSPE

CTU in Prague).

Syllabus of lectures:

1st Past and present of computer networks. Topology, used principles and technologies.

3rd Network protocols, TCP/IP communication

4th Internet services. Remote access, electronic mail (formats, transmission, access to the mailbox)

5th Security of services, tunneling

Syllabus of tutorials:

1st Access to e-mail, formatting and transmission

2nd Secure encrypted communication channel, tunneling

3rd TCP / IP communication (option C, C + +, Java, etc.)

4th Remote access (telnet, ssh, XWindows, Remote Desktop, VNC)

Study Objective:

Knowledge: use of secure channels, principles of electronic mail, directory services and their use, public key infrastructure, firewall principles.

Skills: Build a secure transmission channel, work with certificates, basic routing and firewall settings.
