Security and Privacy of Networked Computer Systems

  • 150 hours
  • 10 weeks (11am to 1pm each Friday) + optional assessment
  • 21 Jan 2022

Overview

This practical short course covers the design, development and evaluation of secure computer systems and networks.

In particular, it will focus on security and privacy challenges in a "big data" world. You'll learn about new and emerging technologies, such as blockchains and distributed ledger technologies, which hold significant promise for security and privacy.

You'll also learn how to implement and test secure networks in practical lab sessions.

This course is run by UCL's Department of Electronic and Electrical Engineering.

Dates, assessment and certificates

Classes will be held from 11am to 1pm on Fridays, from 21 January to 25 March 2022.

Teaching will take place in person with some materials available online. Please note, dates and teaching arrangements may need to change in response to government guidance around Covid-19.

The assessment will be based on a mini project covering various elements of the course. This will involve setting-up and demonstrating a system, and writing a 5,000 words report.

If you complete the course but not the coursework, you'll receive a certificate of attendance.

If you complete and pass the coursework, you'll get a certificate stating this, which includes your pass level.
