Cyber Security (EPSRC Centre for Doctoral Training)

About the course

The CDT in Cyber Security is a four year interdisciplinary doctoral programme which looks at the topic from a range of angles including computer science, social science, business and international relations. The core research themes are cyber-physical security, real-time security, assurance and big-data security.

As the technologies of cyberspace come to inhabit all parts of everyday life, cyber security has become everyone’s problem. We face a growing collection of adversaries who are agile, opportunistic, and increasingly strategic, developing an ecosystem of suppliers involved in delivering elements of attack capability. They seek to defraud consumers, exploit their trust, or invade their privacy; to misappropriate corporate secrets and intellectual property; and/or to disrupt the operation of the state or critical infrastructure.

The CDT sets out to educate a new generation of research leaders as well as the highest tier of security professionals, who appreciate the real-world challenges which arise from security needs in existing and emerging contexts, equipped with both the expertise and adaptability to address those needs. You will need to become as agile in your thinking as the attackers are, and as resourceful in defence as their counterparts are in attack.

As a student in the CDT you will spend the first year in a group with the other CDT students in your cohort on an intensive programme of study designed to introduce the dimensions and nature of the challenge of cyber security from a range of academic perspectives.

These will include as a core, cyber security principles (systems and operations), usability, security risk management, system architectures and high-integrity systems engineering. There will also be a range of courses in research methods and tools. This understanding will be placed in the context of courses in business processes, policy and governance, international relations, and criminology. You will have access to leading thinkers and practitioners in cyber security.

Following this intensive education, you will spend the summer of the first year undertaking two mini projects in diverse areas, usually involving placement in a company or government organisation. You will normally choose these from a list proposed by supervisors and sponsors. One or both of these mini projects will typically form the basis for your long-term research project.

For this substantive project, you will be based in one of the departments contributing to the CDT, and undertake supervised research in the usual manner for a DPhil. The normal duration of this project will be three years, after which you will submit a thesis and be examined in the usual way.

During the three years of the individual research project, you will retain contact with the CDT, returning for skills training, an annual conference and other events.

The CDT programme also includes “Deep Dive Days” which are a supplement to the academic programme of classes, lectures, and seminars. They are an opportunity to interact with someone who practices cyber security daily: technologists, CISOs, security consultants, lawyers, government risk owners and more. Some of these are visits and field trips; others take the form of a master class in Oxford. Deep Dives allow the academic material to be illustrated, and challenged, by exposure to everyday practice. Sometimes, they can become the basis of ongoing project work too.

Graduate destinations

The CDT expects students to progress into diverse employment areas in line with the CDT's multidisciplinary approach. Future career destinations may include government or consultancy employment, furthering an academic career within the field or pursuing a cutting edge industrial research career. Graduates will leave the CDT with the skills necessary to succeed in their chosen career path.

Entry requirements for entry in 2017-18

Within equal opportunities principles and legislation, applications will be assessed in the light of an applicant’s ability to meet the following entry requirements:

1. Academic ability

Proven and potential academic excellence

Applicants are normally expected to be predicted or have achieved a first-class or strong upper second-class undergraduate degree with honours (or equivalent international qualifications), as a minimum, in computer science and related topics, social science and related topics, international relations, business, internet security, or public policy and related topics.

For applicants with a degree from the USA, the minimum GPA sought is 3.6 out of 4.0.

However, entrance is very competitive and most successful applicants have a first-class degree or the equivalent.

A master's degree is not essential but would be an advantage. Professional experience is not essential but is considered alongside academic ability. 

If you hold non-UK qualifications and wish to check how your qualifications match these requirements, you can contact the National Recognition Information Centre for the United Kingdom (UK NARIC).

No Graduate Record Examination (GRE) or GMAT scores are sought.

Other appropriate indicators will include:

Supporting documents

You will be required to supply supporting documents with your application, including references and an official transcript. See 'How to apply' for instructions on the documents you will need and how these will be assessed.

Performance at interview(s)

Interviews are normally held as part of the admissions process.  

Candidates are shortlisted on the basis of academic ability and usually based on a ratio of 2:1, interviews to offers. All shortlisted candidates will be invited to attend an interview either in person or via Skype (with video). 


Publications are not essential.

Other qualifications, evidence of excellence and relevant experience

Research or working experience in areas related to cyber security may be an advantage. Evidence of training in cyber security or related topics may be an advantage. Professional experience is not essential but may also be an advantage.

2. English language requirement

Applicants whose first language is not English are usually required to provide evidence of proficiency in English at the higher level required by the University.

3. Availability of supervision, teaching, facilities and places

The following factors will govern whether candidates can be offered places:

  • The ability of the Department of Computer Science (and/or the Oxford Internet Institute, Said Business School, Oxford eResearch Centre and/or the Blavatnik School of Government, if appropriate) to provide the appropriate supervision, research opportunities, teaching and facilities for your chosen area of work. 
  • Minimum and maximum limits to the numbers of students who may be admitted to Oxford's research and taught programmes.

The provision of supervision, where required, is subject to the following points:

    • The allocation of graduate supervision is the responsibility of the Department of Computer Science (and/or the Oxford Internet Institute, Said Business School, Oxford eResearch Centre and/or the Blavatnik School of Government, if appropriate) and it is not always possible to accommodate the preferences of incoming graduate students to work with a particular member of staff. 
    • Under exceptional circumstances a supervisor may be found outside the Department of Computer Science (and/or the Oxford Internet Institute, Said Business School, Oxford eResearch Centre and/or the Blavatnik School of Government, if appropriate).
    • Where possible your academic supervisor will not change for the duration of your course. However, it may be necessary to assign a new academic supervisor during the course of study or before registration for reasons which might include sabbatical leave, maternity leave or change in employment.

4. Disability, health conditions and specific learning difficulties

Students are selected for admission without regard to gender, marital or civil partnership status, disability, race, nationality, ethnic origin, religion or belief, sexual orientation, age or social background.
