Governments, businesses, and private citizens all use computers on a daily basis. Cyber security exists to protect computer systems and shared data from theft or damage by any presence that plans to do harm. Security is a constant issue as technology changes and criminals circumvent existing safety measures.

New Zealand is an island country in the southwestern Pacific Ocean. The country geographically comprises two main landmasses ‒ that of the North and South Islands ‒ and numerous smaller islands. Overseas students need to have a student visa and a reasonable level of cash to spend in order to undertake a course of study at a New Zealand based educational institution. New Zealand educational institutions will inform the appropriate immigration authorities if a student ceases to attend their enrolled courses, who may then suspend or cancel that student's visa. Educational institutions often also exchange this enrollment and attendance data electronically with other government agencies responsible for providing student assistance.

Graduate diploma courses often take somewhere between one to two years to complete, and are usually offered to students already holding college degrees. Students might expect better job prospects in the relevant field after graduating from one of these programs.
