Description:

Instead of relying exclusively on physical security and separate networks, more and more applications are moving to shared networks like the Internet. These applications include the electronic banking and commerce, virtual private networks and the transfer of sensitive medical or personnel data. A combination of security measures, including cryptography and firewalls, need to be integrated into network architecture, protocols and implementations to offer reasonable assurance as to privacy and user identity. The course will provide the necessary foundations for network security, including encryption techniques, design of secure systems and protocols as well as enhancements for existing protocols like electronic mail, WWW and the Internet protocol. While the majority of the material will be drawn from the text, additional topical areas such as electronic cash, the WWW security protocol SSL and Java security issues will be covered.
