Diploma in Cybersecurity of Defence Data Links
Online postgraduate diploma of 800 hours in cybersecurity of defence data links. 8 modules covering tactical data links, cryptography, threat modelling, physical layer resilience, gateway security, accreditation and secure operation under STANAG 5516, NIST SP 800-53 Rev. 5 and Royal Decree 311/2022, with an assigned technical tutor.
Diploma in Cybersecurity of Defence Data Links — studying from South Africa
South Africa has a established defence industry centred on companies such as Denel and Paramount Group, with capabilities in land systems, armoured vehicles and munitions. The sector supports engineering roles in systems integration, vehicle design and test and evaluation. Defence procurement and export controls are overseen by government bodies, and the industry works closely with the South African National Defence Force. Engineers in this field typically combine mechanical, electrical and systems skills.
Fees for South Africa: R 20 400 (South African rand), with instalments and employer sponsorship available.

Questions from South Africa
Which South African bodies regulate or recognise defence and military engineering professionals?
Engineers in South Africa are registered through ECSA under the Engineering Profession Act, and defence programmes are guided by institutions such as the South African National Defence Force and Armscor, which set their own requirements. SEIUM is a private online institute, and its qualifications are not state degrees or accredited by a national body. Recognition is decided by these bodies and your employer, so confirm with them first.
Would this qualification help me find work in South Africa's defence or land systems sector?
South Africa has a defence industry with state-linked entities and private contractors, and employers usually require security clearances, relevant experience and recognised qualifications. A private online programme may support your application but does not guarantee employment or clearance. Check requirements with prospective employers, as roles in this sector can be sensitive and tightly controlled.
Can I study alongside a job, and are there funding options?
The course is 100% online and taught in English, so you need strong English, and no student visa is needed to study from home. Master's programmes are 1,900 hours, postgraduate diplomas 800 hours and specialist courses 300 hours, each with an assigned technical tutor. Fees are payable in instalments, and employer sponsorship is possible, so ask whether your employer would fund part of the training.

How you'll learn
A 100% online programme on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within the intake, so it fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Wireshark, MATLAB Communications Toolbox, GNU Radio and Suricata, in free, academic or evaluation versions. Testing is studied through real procedures for data link interoperability testing, authorised security testing and laboratory traffic analysis. Assessment is continuous by module, plus the final project.
Standards covered: STANAG 5516, NIST SP 800-53 Rev. 5, Real Decreto 311/2022, MIL-STD-6016, MIL-STD-3011, NIST SP 800-37 Rev. 2, FIPS 140-3.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
