Overview

• A general introduction to networks and networking protocols, especially TCP/IP.
• Overview of important Internet application protocols: HTTP, SMTP, DNS, LDAP.
• A study of cryptographic algorithms including symmetric and asymmetric techniques and the distinction between encryption and signatures.
• Security mechanisms used with operating systems, including: usernames/passwords, access control lists and capabilities.
• Problems of network security including wiretap, replay, masquerade and denial of service. Mechanisms to provide security such as firewalls and VPNs.
• Viruses and worms.
• Distributed Mechanisms, including client authentication (Needham-Schroeder, Kerberos and others); public key infrastructures and certification, with treatment of chains and authority, and the problem of revocation.
• Securing email systems: PGP and S/MIME
• Identity management systems: e.g. Shibboleth, Passport, CardSpace, OpenID.
• Basic introduction to information risk management and information security management.
• Security of IEEE 802.11 networks (aka Wi-Fi), presentation and discussion of their security protocols: WEP, WPA, WPA2, IEEE 802.11i and RSN.
