Some doctorates in cybersecurity welcome applicants with only a bachelor's degree in a related field. Others require a master's degree for admission. An applicant's highest degree should always come from an accredited institution.

Cybersecurity doctoral programs often demand a minimum 3.0-3.5 undergraduate GPA. Some schools require GRE scores, but others admit applicants on the strength of their academic and professional backgrounds alone.

In addition to an undergraduate or graduate degree, prospective students need to submit an application, an essay, a resume, and letters of recommendation. Applicants usually pay an application fee ranging from $50 to $100.

Degree Options

Prospective students can consider several options when looking at a doctoral degree in cybersecurity. For instance, online programs offer flexibility and study-life balance, but an on-campus doctorate in cybersecurity provides face-to-face time with professors and peers.

A degree's curricular focus varies by program. Ph.D.s in cybersecurity emphasize designing and completing a research project with a goal of producing researchers and teachers. D.Sc. degrees elevate technical leadership with a goal of producing technical specialists and organizational leaders.

Even within cybersecurity Ph.D. programs, different universities have carved out their own areas of expertise. Subdiscipline specialties may include cybersecurity policy, emerging threats, or enterprise risk management.

Popular Cybersecurity Courses

Courses vary by school. A standard curriculum includes core courses in information security, information governance, and risk management. Students may also take concentration courses in areas like digital forensics or blockchain. A doctoral degree in cybersecurity concludes with a research sequence leading to a dissertation or capstone project.

  • Information Technology in a Global Economy

    This course explores the theories, development, and impacts of national and international public policies as they affect information technology. Enrollees learn the skills required to lead organizations through disruptive policy initiatives that establish new regulations.
  • Emerging Threats and Countermeasures

Enterprises, for example, face different threats and require different resources than the military. In this course, learners explore current trends and learn to solve security problems using new technologies.
  • Human-Computer Interaction

    Students learn to view human-computer interaction (HCI) from several complex social and organizational perspectives and to understand the breadth of HCI's impact. This course looks at advanced concepts of design, evaluation, implementation, and application for interactive human-computer experiences.

How Much Will a Doctoral Degree in Cybersecurity Cost?

Several factors help determine the cost of getting a doctoral degree in cybersecurity. Things like state residency, degree format, available funding, and school prestige can all affect tuition prices.

According to the National Center for Education Statistics, in the 2019-20 academic year, the average public institution tuition was $12,410, while private institutions charged $26,597. Nonprofit, private colleges and universities charged an average of $28,430 while for-profits charged $14,289.

Students may incur other costs during their studies. Whether living on campus or studying from home, degree-seekers still need to budget for housing expenses, food, transportation, healthcare, insurance, and other expenses. Some institutions also charge technology fees or graduation fees.
