Overview of PhD Programs in Cyber Security

A PhD in Cyber Security is rigorous, research-focused degree where you can devote yourself to a particular area of interest (e.g. human-centered computing, cyberinfrastructure, embedded systems, etc.). Doctoral degrees may take 5-7 years to complete.
A PhD is not required for most corporate cyber security careers. Instead, it is tailored towards students who are interested in research-based jobs such as:

  • Corporate researchers
  • University faculty
  • Policy advisors

Take a deep breath before committing to a PhD program. It can be an expensive, difficult and frustrating process. The rewards are great, but so are the sacrifices.

Types of Cyber Security PhD Programs

PhD in Cyber Security

Cyber security is a relatively new field, so it’s rare to find a degree explicitly called “PhD in Cyber Security”. Instead, most universities choose to offer a PhD in Computer Science or Computer Engineering with the option to focus on security-related issues.

PhD in Computer Science – Security Focus

This is the most common PhD degree for cyber security researchers. It often examines technical and theoretical concepts of computer science and information security. With this degree, you could be expected to demonstrate your grasp of fundamental computational practice (e.g. algorithms, engineering, database management, architecture, artificial intelligence) before you’re allowed to attack your dissertation.

PhD in Information Assurance

Information assurance is concerned with every aspect of protecting information systems – from the legitimate use of system resources to the impact of regulatory changes. In consequence, PhD programs in Information Assurance may (but don’t always) have an interdisciplinary feel to them. For example, in additional to technical puzzles, PhD students could be investigating what kinds of effects law, policy and human behavior have on security measures.

Cyber Security PhD Curriculum

The standard format for a U.S. PhD program is two years of graduate classes and qualifying exams, followed by 3-5 years of independent research culminating in a detailed, scientific account of your work (i.e. your dissertation).
We’ve listed some sample courses for those first 2 years of study, but your individual curriculum will be unique to your research concentration. Most PhD students plan out their course of study and their choice of classes with a graduate advisor.

Years 1-2: Sample Courses

  • Theory of Computation
  • Computer Systems, Networks and Architecture
  • Network Security
  • Applied Cryptography
  • Security Risk Management
  • Cyber Law
  • Homeland Security
  • Advanced Algorithms
  • Artificial Intelligence
  • Software Engineering
  • Graphics and Visualization
  • Data Warehousing
  • Machine Learning
  • Information Theory
  • Applied Probability
  • Neural Networks
  • Etc.
Note: If you already have an MS in Computer Science or similar, you may be able to transfer some of your credits.

Years 3-5: Sample Format

These are the independent research years. During this time, you will be expected to submit (and defend) a dissertation proposal to the Dissertation Committee. They will decide whether:

  1. Your dissertation topic is original and will make a significant contribution to the field of cyber security
  2. You have the skills and background knowledge to complete your dissertation
  3. Your research plan is sound and your goals are realistic

While you are working on your dissertation, you may be required to write progress reports, teach undergraduate classes and present talks on your research. This process ends when you submit your dissertation for publication.

Dissertation Defense

The very last hurdle is an oral examination (a.k.a. dissertation defense). You will once again stand in front of a Dissertation Committee to defend your work and its originality. The committee is often a mix of internal faculty members and external experts. Seo Portfolio

Cyber Security PhD Admission Requirements

Standard Requirements

Schools are interested in original thinkers with a burning interest in a specialized field of knowledge and the ability to complete significant and relevant research.
Universities take a variety of criteria into account when they’re making their decision. Here are some standard admission requirements:

  • Bachelor’s degree from a regionally accredited institution
  • GPA of 3.0 or more (Grade B or above) in computing/math courses
  • Excellent GRE scores
  • Relevant professional experience
  • 3 letters of recommendation
  • Statement of purpose
  • Research work, including publications

International applicants will also need to provide their scores on the TOEFL examination.

Do I Need a Master’s Degree?

Probably not. A lot of universities will grant you a master’s degree after you’ve completed the first 2-3 years of graduate coursework.
Depending on your area of interest, you may be able to apply even if you don’t have a degree in CS or Cyber Security. However, schools will want to see that you have significant background expertise in the subject.
