Why, I hear you ask, am I going back to basics to learn about a subject in which I am already pretty well versed?
It is true that I have been exposed to cyber security principles and practice for almost 20 years by virtue of my primary degree in Computer Science, internship and subsequent career in both technical and non-technical roles. Heck I’ve even spent the last three years as Technical Marketing Manager of QUB’s Centre for Secure Information Technologies (CSIT), the UK’s Innovation & Knowledge Centre for Cyber Security, a role which sees me regularly speak to businesses, students and contributing to TV, radio and print media on the subject of technology vulnerabilities, threats and breaches. The role also involves bringing new cyber security technology, the output of much of our ground-breaking research, to market.
I participated in the 8 week long online course for three reasons:
- I’m big enough to admit that I don’t know it all – even in my own field of expertise there is always scope to learn new approaches and relearn concepts that I may have forgotten. This course offered me a chance to look at cyber security with fresh eyes.
- Working day to day in a research and innovation environment at the very bleeding edge of cyber security technology it is all too easy to forget how the person on the street views my area of expertise. This course allowed me the chance to step back from that edge, think about cyber security from an end user perspective and consider how our research and technology could be applied to solve the simple and mundane as well as grander challenges.
- Lastly, I wanted to kick the tyres on it. Prior to this course launching I had been asked by a number of organisations if we at CSIT could deliver similar entry level training. We had already delivered some internally to the wider QUB staff body and the question was whether or not we should package that up and produce an offering to business and community groups. I wanted to assess if the OU course would rule that effort worthless.
Did it pass muster?
In a word – yes.
The course surpassed my expectations to be honest. It wasn’t patronising, while it assumed no prior knowledge it explored more complex aspects of cyber security explaining them in an engaging way.
Those charged with information and cyber security in organisations and the wider world can often be seen as bad guys and girls in their own right. Blocking access to fun stuff on the internet and not allowing the latest whizzy consumer devices onto corporate networks without a satisfactory reason from an end-user stand-point. The first week explored the threat landscape in depth, explaining why cyber security matters to everyone and laid a solid foundation for the remaining seven weeks.
Over the last number of years many of the times I have been invited by the media to provide analysis on cyber security events has been due to password breaches.
It’s one of the reasons I’m so passionate about bringing our LIOPA lip biometric technology to market. Week two covers the whole gambit of authentication even going so far as covering salting, hashing as well as multi-factor which is thankfully becoming the norm for most online services.
One area where I disagree with the course is its highlighting of password manager applications as a solution to remembering multiple usernames and passwords. Personally I see them as a significant risk and prime target for cyber criminals. Hack those and you have the master key for an individual’s whole online life.
Weeks 3 and 4 cover Malware and Networking & Communications adequately but it was Week 5’s focus on Cryptography which drew my attention. It’s an area which we at CSIT carry out significant research in areas such as Post-Quantum Cryptography,Physical Uncloneable Functions (PUF)-PKI and Fully Homomorphic Encryption.
As the family IT go to guy weeks 7 and 8 coverage of what to do when things go wrong and managing risks is welcome. Its also a timely reminder for everyone to fully consider their own vast stores of digital information, prioritising which bits are most important and putting in place a regular backup routine to protect against loss.
Have I changed how I think about my own cyber security after completing this course?
Absolutely. Will I tell you the changes I have implemented as a result? Absolutely not. Why make it easier for the cyber criminals? Individuals and organisations are under constant attack. It is a case of when and not if your cyber security defences will be probed and breached – why make it easy for them.
Wider lessons for going back to basics.
Sometimes subject matter experts can be a little reluctant to admit that they may not be across all the basics in terms of their field. Instead they baffle the uninitiated with the more advanced aspects of their product or service. Looking once again from an amateur’s perspective can be enlightening.
Participating in this course has also opened my eyes to interesting use cases for some of CSIT’s innovations.
While this course may close off opportunities for us as an organisation to deliver similar training ultimately it educates a greater number of people in respect of cyber security who will demand greater security from service providers and technology providers. If it encourages more students to consider applying for our MSc Cyber Security or consider carrying out PhD research with us then even better.
Ultimately this will stimulate further the burgeoning global cyber security market benefiting CSIT and the wider industry in which we operate.
