Protocol processing and security

Individual course

The course covers protocol engineering and design, protocol processing system design and implementation for a given application, interdomain routing in the Internet and protocol processing in routers, the DNS system and its vulnerabilities, threats to the security of the Internet routing system and how to mitigate them. In terms of protocols, the course focuses on IP, IPv6 and BGP protocols.

Learning outcomes

After the course the participants

  • will have developed an understanding of characteristic protocol processing functionality needed in protocols designed for environments with intermediate stations between source and destination devices
  • will understand the critical importance of protocol processing system implementations in data transportation intensive networks
  • will have the protocol engineering understanding necessary in specifying protocols for given target applications
  • will be knowledgeable in the security threats faced by the Internet core routing system and the DNS system and have an understanding in mitigating these threats.

Case studies and project work focus on the internet core routing system.
