Course content
The course begins with the introduction to the security of TCP/IP networks in general and the methods of network scanning including demonstration of various attacks. Examination of methods of (Internet) network securing going from traffic filtration, over proxies and address translation, firewall, so far to tunnelling and VPN, then the introduction to electronic certificates and PKI infrastructure, its application, and in the end of the course the selected encrypted aplication protocols like eg. IPsec, DNSSec, SSL/TLS (OpenSSL) or SSH are covered. In practices students first try to do some simple attack on non-secured (local) network and then they learn how to apply the methods of its securing and deploying secured protocols. 1. Intro: intro to cryptography and authentization, network secutiry (TCP/IP) in general, attacks (DoS), detection of attacks (IDS) 2. Security of network technologies: network scanning (Wireshark, nmap), data integrity, attacks, wireless networks (WiFi), tunnelling, VPN 3. Internet security: filtration, proxies, address translation (NAT), firewall and DMZ 4. Internet security: tunnelling, VPN, aplication proxies and gates, SOCKS 5. PKI infrastructure: certificates, certificate authorities and PKI infrastructure 6. Application of PKI: elektronic signature and banking 7. Encrypted and authentization protocols: IPsec, RADIUS, LDAP, Kerberos, DNSSec 8. Encrypted and authentization protokols: SSL/TLS (OpenSSL), S/MIME, SSH
