Threats and attacks, OS, web and cloud security, cryptography, identity and access, incident response and penetration testing.
Home › Courses › Cybersecurity vs Network Security
Cybersecurity (Computer Science 270) is the broader course: threats, operating system, web and cloud security, identity and access, incident response and penetration testing. Network and Systems Security (Computer Science 252) stays with defending networks and systems: risk, cryptography, firewalls, wireless hardening, VPNs, IDS/IPS and change management. Cybersecurity carries both ACE and NCCRS recommendations; Network and Systems Security carries NCCRS only.

From the syllabi: what only one course covers, and where they meet.
| Cybersecurity | Network and Systems Security | |
|---|---|---|
| Course code | Computer Science 270 | Computer Science 252 |
| Chapters | 12 chapters | 9 chapters |
| Instructional hours | 67 hours | 57.5 hours |
| ACE | Yes: ACE ID UPIS-0024 | No: NCCRS only |
| NCCRS subject areas | Cybersecurity, Computer Science and related fields | Cybersecurity or Information Technology |
| Lab lessons | Online lab lessons in both | |
| Prerequisites | None listed in either syllabus | |
| Final exam | 100 multiple-choice questions | |
Both are self-paced: quizzes and the assignment are open-book, the final is proctored, and 70 or higher passes.
Broad security: Cybersecurity. Network defense: Network and Systems Security.


Cybersecurity (Computer Science 270) covers security as a whole: threats, operating systems, web and cloud, identity and access, incident response, governance and penetration testing. Network and Systems Security (Computer Science 252) stays with networks and systems: risk, policy, cryptography, firewalls, wireless, VPNs, access control and IDS/IPS. Both cover cryptography, access control and incident response, and both have online lab lessons.
Cybersecurity: ACE recommends 3 semester hours, ACE ID UPIS-0024, and NCCRS recommends 3 as well. Network and Systems Security carries an NCCRS recommendation only: 3 semester hours in Cybersecurity or Information Technology.
Yes. They are two separate courses with their own codes, and neither lists a prerequisite. Cybersecurity gives the wide view; Network and Systems Security adds wireless hardening, perimeter defense and configuration management. Ask your school which requirement each one meets.
Cybersecurity: NCCRS recommends 3 semester hours, lower division, in Cybersecurity among other subjects; ACE recommends 3 (ACE ID UPIS-0024). Network and Systems Security: NCCRS recommends 3 semester hours, lower division, in Cybersecurity among other subjects.
Cybersecurity: Cybersecurity, Computer Science, and related courses of study in Emergency Management, Intelligence Studies, or International Studies. Network and Systems Security: Cybersecurity or Information Technology. Your college decides which requirement each one fills.
Cybersecurity is longer by its syllabus. Cybersecurity: 12 chapters and 67 instructional hours. Network and Systems Security: 9 chapters and 57.5 instructional hours. Both are self-paced, so you finish as fast or as slow as you want.
No prerequisites are listed for Cybersecurity and Network and Systems Security, so the order is up to you and your program.
Both have the same kind of final: 100 multiple-choice questions.
A pass is 70 or more. The grading scale on your UPI Study transcript shows how 70 maps to a letter grade; for most colleges it is a C.
