Principles and practices of computer network security. Cryptography, authentication protocols, digital signatures, IP/E-commerce security, VPNs, firewalls, and network intrusion detection. CSE 408 cannot be taken for credit in addition to ESE 360.

CSE/ISE 310 or CSE/ESE 346

• Develop basic knowledge of cryptographic algorithms and techniques used in network security
• Demonstrate how these techniques are applied in protocols and software applications to solve network security problems
• Show how to secure networked systems in practice

We are planning on changing CSE 408 and 508 so that they are offered in Spring semesters, starting Spring 2011. (Currently, and in the next academic year 2009-10, these courses are offered in Fall semester.) At the same time, CSE 409 and 509 will be switched to Fall semesters from the current Spring semester schedule, starting in Fall 2010.
