Start date1 October 2019
This research project has funding attached. Funding for this project is available to UK citizens. A stipend of £22k tax free and fees are covered per year.

The project aims to consider the application of machine learning and decision support strategies to make sense of vast array of cyber threat information. It will define models for identifying attack vectors, levels of trust in users, and then identifying changes of user behaviour that indicate propensity to move from trusted to threatening behaviour.
This research is supported by the UK Government and it is in partnership with Surevine and BAE Systems Applied Intelligence. The PhD student will work at the University of Surrey, at the Surrey Centre for Cyber Security (SCCS) and with the Centre for Vision and Signal Processing (CVSSP).
If you are fascinated about machine learning and security and you have knowledge of any of the following: machine learning, cyber risks, web development and APIs, please contact the supervisor for any further enquiries about the post or apply directly.
Information sharing of threat intelligence across different organisations is becoming increasingly important in order to improve organisations’ ability to defend against cyber attacks. Moreover, national security and government organisations such as NCSC and NIST are driving initiatives and awareness of the need to develop cyber threat information sharing relationships. There are a number of platforms currently being developed to support a common infrastructure and protocols for sharing cyber threat information. The adoption of these platforms is gaining wide industry support.
With wider scale adoption two main research challenges emerge around the improved utility of the information and its trustworthiness which goes beyond the functionality offered currently by the existing platforms:
- How can an assessment be made of the information being stored in the platform in order a) to customise and categorise the information presented to users
- How can the threat information posted to a platform be guaranteed to be from a particular source?
The main objectives of the studentship are:
- To identify what can be done in order to analyse the impact of the threat information
- To develop machine learning algorithms that could be new and/or adapted from existing algorithms. These will be evaluated in the context of information sharing platforms, and to evaluate them in the context of real information from different industry sectors
- To develop machine learning and security techniques to improve the assessment of users’ trustworthiness within information sharing platforms.
The technical approach will focus initially on using machine learning techniques in the context of information to decide what information is most relevant to a user of a platform and also clustering information based on semantic content similarity in order to derive a clearer picture of the scope of the threat.
There is also scope in the studentship to pivot to investigate the scalability of registering users to access platforms via decentralisation, since users are not just people, they may be external data sources.
