Dakota State University Online Cyber Defense, MS

Dakota State University's Master of Science in Cyber Defense is a technical, NSA-designated degree at a public university that has built its identity around cyber. At 30 credits and $495.70 per credit, tuition is $14,871 before any delivery fee.

It asks for a computing background and a 3.0 GPA, so it's best for people who already code or administer systems and want to go deeper into offense, forensics and incident response.

Dakota State University (DSU) is a public university in Madison, South Dakota, with a college focused on cyber. About 3,774 students are enrolled, and 87% of graduate students study exclusively online. The master's in Cyber Defense can be completed fully online or on campus, so the online cohort sits beside a campus program instead of replacing it.

The degree is 30 credits, with fall, spring and summer starts. The National Security Agency (NSA) has designated the program as a Center of Academic Excellence in Cyber Defense (CAE-CD). That designation matters if you're aiming at federal or defense-related work, where employers often look for it.

Federal data counts 32 master's-level awards a year in this field at DSU. The school admits 88% of applicants.

The full rubric is on the methodology page.

The online rate is $495.70 per credit, which covers tuition and fees for 2026-2027. For 30 credits, that is $14,871. Students who aren't residents of South Dakota pay an extra $117.70 delivery fee in computer science (CSC) courses, so the final number depends on your course mix and where you live.

IPEDS, the federal data system, lists a higher on-campus charge of $622 per credit, so the online rate is the better deal for remote students. Do the math with the online rate, not the campus figure on the national comparison sites.

No GRE is required, which saves you the test fee and the prep time.

30 credits at $495.70 a credit comes to $14,871 in tuition, before fees.

Who It Fits

• Developers, system administrators and network engineers who want to move into security without leaving their current job.
• Anyone aiming at government, defense or contractor work, where an NSA-designated program carries weight.
• Students who want a low-cost public master's and can handle technical coursework.
• People who want to choose a direction. The program offers a technical specialization and a security management and compliance specialization.

Who Should Skip It

• Career changers without a computing degree. Admission expects a bachelor's in computer science, computer engineering or software engineering, or a closely related field.
• Applicants under a 3.0 GPA, since that is the stated minimum.
• Non-residents who take computer science (CSC) courses and don't want an added delivery fee of $117.70.

The notable courses are offensive and investigative. Offensive Security teaches you to attack systems the way an adversary would. Network Security Monitoring and Intrusion Detection and Incident Response cover spotting and handling an attack in progress. Digital Forensics and Malware Analysis and Threat Analysis cover what you do after something has gone wrong.

That mix reflects the degree's name. Cyber defense here means understanding attackers well enough to catch them, not just configuring firewalls.

The two specializations point you in different directions. The technical specialization goes deeper into the hands-on material. The security management and compliance specialization suits someone heading toward oversight, policy or audit roles. Pick based on the job you want in five years, not the one you have today.

Standout Features

• NSA designates the Master of Science in Cyber Defense as a Center of Academic Excellence in Cyber Defense (CAE-CD)
• Ranked #24 on the most affordable online cybersecurity master’s programs list (Cybersecurity, 2026)

You can finish the whole degree online. DSU describes the choice as fully online or on campus, and 87% of its graduate students study exclusively online, so you won't be the odd one out.

Three starts a year, in fall, spring and summer, give you flexibility without the constant churn of a six-start schedule. Plan around the next start date, and ask when the courses you want are offered, because specialized electives don't always run every term.

The lab-heavy courses, such as offensive security and malware analysis, usually need a capable computer and a good internet connection. Ask what the school provides in virtual labs and what you need to supply.

The NSA designation as a Center of Academic Excellence in Cyber Defense is the headline credential. It is a government recognition of the program's curriculum. Ask DSU which scholarships or federal hiring pathways, if any, that designation connects to today.

Certification exams are a separate step from this degree, so plan to pick them based on what your employer values.

On outcomes, DSU's overall graduation rate is 51%, and the 8-year completion rate for students who transferred in is 44.5%. Those figures cover the whole school, not just this master's.

DSU also offers Ph.D. programs in Cyber Defense and Cyber Operations if you want to continue.
