Is a Cyber Security PhD Worth It? (The Best Answer)

Cyber security, is a domain where specialized skills and knowledge are highly sought after. And if you’re reading this, you’re already considering enhancing your credentials by pursuing a cyber security PhD.

However, this isn’t a decision to be taken lightly. This article is intended to provide a comprehensive overview of the considerations, commitments, and potential career paths associated with becoming a “Doctor” of cyber security.

Read on to gain insight into the nuanced aspects of this decision, from understanding the pre-requisites for admission to exploring potential job opportunities and evaluating the financial return of a cyber security PhD.

My Opinion

No, a PhD in cyber security isn’t worth it unless you’re aiming for a career in research, academics, industry regulation, or leadership (aka CISO). Why?

Honestly, a PhD in cyber is only designed for people with a distinct mindset. You’ve got to have a deep-rooted passion for cyber security with a drive to make meaningful contributions to the field.

You should NEVER do a PhD in cyber security for the money! But, if you have that passion and drive, the personal satisfaction from a PhD should outweigh all other considerations.

Let’s look at some of those considerations…

Most cyber security positions don’t require a PhD. Although getting a PhD makes you a specialist in your field, it also has the unfortunate side effect of over qualifying you for certain roles.

For instance, no one’s going to hire a PhD candidate for a cyber analyst role. On the other hand, it opens doors that a bachelor’s or master’s degree can’t.

For instance, are you dreaming of a career in academia? Or do you see yourself as a high-level cyber security researcher or policy maker?

If that’s the case, then you should absolutely pursue a PhD. But before jumping in, keep in mind that it also involves a significant commitment to research demanding a lot of your time and resources.

Many have regretted started a PhD that they either couldn’t finish or have invested so much time, they couldn’t quit. What’s worse? You’ll need to give up a full-time salary for about 4-7 years.

Trying to work, even part time, while you’re doing your PhD will be very challenging. Even though some programs offer stipends to help with your living expenses, it’s important to consider a crucial question.

Does the potential financial return align with your long-term goals?

For some people the answer is no. Think about it!

Why would you give up 4-7 years of experience and salary increases only to find that someone with a bachelor’s and a few years of experience is getting paid more? Remember that when you’re working in cyber security, it’s your skills and experience that counts, not your academic knowledge.

I’m not trying to dissuade you from pursuing a PhD of cyber security. But it’s a decision that needs careful thought and advice from industry professionals, career counselors, and your academic advisors.

In the end, the value of a PhD in cyber security isn’t an easy thing to determine. It’s heavily dependent on your career goals, your passion for the field, and your resources.

Can You Get a PhD in Cyber Security?

Yes, you can get a PhD in cyber security. But you’ve got to meet the institutions basic requirements and successfully manage the rigor of academic work.

Cyber security PhD programs typically require students to have a strong academic background in computer science, mathematics, software engineering, or cyber security. And many of the requirements to enter a PhD program are similar no matter which university you’re applying to. It’s usually a matter of submitting transcripts, GRE scores, letters of recommendation, admissions essay, and your resume.

Also, no one can give you the exact prerequisites for a PhD cyber security program because it varies by institution. But I can say, your admission is generally dependent on the program’s area of expertise and level of funding available.

PhD in Cyber Security vs Doctor of Cyber Security (DSc)?

Most of this article focuses on the Doctor of Philosophy (PhD) in Cyber Security. But before I dive too far into the subject, there are some alternative variations of cyber security doctoral degrees to consider.

The specifics can vary by institution, and some programs may blur the lines between these general categories:

  • Doctorate in Information Assurance (DIA)
  • PhD in Cyber Operations
  • PhD in Computer Science – Cyber Security
  • Doctor of Information Technology (DIT) – Cyber Security
  • PhD in Information Science – Cyber Security
  • PhD in Technology Management – Cyber Security
  • Doctor of Science (DSc) in Cyber Security
  • PhD in Computer Engineering – Information Assurance
  • PhD in Informatics – Security Informatics
  • DSc in Information Assurance
  • PhD in Mathematics – Information Assurance
  • As you can see, the naming convention isn’t what you’d expect; however both give you the title of “Doctor”. I know that if you live abroad, the Doctor of Science designation is often held in higher regard than a PhD.

    Do your research, but I will say that if you live in the US, you’re probably better off getting your “PhD in Cyber Security” as it’s more widely understood. That may change in the next decade, but for now it’s probably the safer way to go.

    Why Should You Get a PhD in Cyber Security?

    When you get a bachelor’s or master’s degree, you’re preparing for a career in cyber security, but this isn’t true when becoming a doctor of cyber security. That’s because earning a PhD is mostly about research.

    Your dissertation offers you the opportunity to conduct original research on the forefront of new security technologies. That may even continue after your graduate. Imagine diving deep into a specialized field like quantum cryptography, artificial intelligence in cybersecurity, or blockchain security.

    That’s what a PhD in cyber security offers you!

    How Long Does a PhD in Cyber Security Take?

    A PhD isn’t just about getting a degree; it’s about becoming an expert in your field. And it’s a commitment that usually takes between 4-7 years.

    You’d typically begin your PhD by attending classes, completing projects, and passing exams for advanced cyber security coursework. It might take you about two to three years to finish this part, especially if you’re studying full time.

    If you’re going part-time, you’re looking at an even longer period. Then comes the comprehensive exams or qualifiers, which are usually taken after your coursework is complete.

    These are tough exams that test your knowledge in the field. Here, you’ll need to dedicate several months to prepare for them.

    After passing these comprehensive exams, you’ll then move on to your own research and dissertation under the guidance of a faculty advisor. The time you’ll spend here varies significantly.

    If you’re dedicated enough, you might finish in a couple of years, others may take longer. It really depends on your research topic, your advisor, your personal commitment, along with a bit of luck.

    Don’t forget, you’ll also be expected to teach classes, present at conferences, publish papers, and contribute to the academic community. All these activities take time too.

    How Much Does a PhD in Cyber Security Cost?

    A PhD in cyber security ideally costs $0! That’s right, most PhD students pay almost nothing in tuition because that’s usually covered by the research grant.

    FYI…NEVER enter a PhD program that isn’t fully funded unless you expect to pay out of your own pocket! When applying to a cyber security PhD program, you should really be asking several questions:

  • Is funding guaranteed and for how long?
  • Do your students typically take longer than the guaranteed funding period?
  • Will I still have funding after that period?
  • Are there are out of pocket costs for insurance and student fees?
  • Will I have funding through the summer term and what is the source?
  • Is there a fellowship and how are they are awarded?
  • Where do most of your cyber security students get internships?
  • What are the sources of funding in general teaching/researching/fellowship?
  • What’s the typical teaching/research ratio of funding?
  • Is there funding for conference travel and how they are awarded?
  • How much is the stipend?
  • You really should do you research regarding the total out of pocket costs associated with your PhD program.

    What if you do end up paying tuition out of pocket?

    If you take into account both public and private institutions, the average annual cost of a PhD is about $19,749. Of course, the costs do vary depending on where you study.

    I would suggest you go for a public institution where the average annual cost is just over $12,394, compared to almost $26,621 if you go private. By pursuing a PhD of cyber security at a public institution, you’d save approximately $57,000 over four years.

    If you can have your employer cover the costs, then that’s great! However, if you need help, there are scholarships and grants designed to help you with those costs.

    What’s even better is if you have the time to work to gain real-world experience. You should take the time to apply for internships, fellowships, or assistantships.

    Whatever you decide, try to find an option that provides you with invaluable experience while providing you enough money to cover your living expenses. Here’s an article that talks all about how to get a cyber security internship!
