Objectives
The objective of this course is to analyze the main mechanisms and protocols for network security. It deals with the bases of modern cryptography, the various security protocols, possible network threats, and secure countermeasures.

Program
1) Introduction to modern cryptography
Symmetric cryptography (3DES, AES, etc) and asymmetric cryptography (RSA, Diffie-Hellman)
Hash functions and Message digest
Digital signature, digital certificates, certification authorities, X.509/ PKI (Public Key Infrastructure) and PGP (Pretty Good Privacy)

2) Protocols for network security
Authentication protocols (CHAP, EAP, RADIUS, Diameter)
Communication security at IP layer (IPSec), and transport/application layer (TLS, SSH)
Virtual Private Networks
Security in wireless local access (IEEE 802.1x, IEEE 802.11i)

3) TCP/IP vulnerabilities
Possible attacks and countermeasures (sniffing, network and port scanning, IP spoofing, flooding, buffer overflow, etc)

4) Network security
Firewalls (packet filtering, application level gateways, proxy, NAT, bastion host, DMZ), and
Intrusion Detection Systems (IDS)

Laboratory activities
Laboratory activities on vulnerability scanning, firewall configuration, digital certificate management, VPN/IPSec configuration, and other topics.


Prerequisites
