Diploma

Starting from the point of view, Hacking doesn't require eligibility of academics. Hacking is just a skill which requires, Coding Knowledge, Network Knowledge, Server-side Scripting Knowledge, Computer Hardware Knowledge and Testing Knowledge. Coming to the part, if you saw the articles, the children are around 5 - 11 years of age are hacking networks, finding zero-day flaws in software, etc. So this shows hacking doesn't require any academic courses. learning to hack through any certification such as EC - Council CEH, (ISC)2s CISSP, CISA and CISM from ISACA and OSCP from Offensive Security will improve the professional skills of hacking.

Both, degree and Diploma are types of recognition conferred on a person on the successful completion of an educational course. Major differences between a Diploma and degree are listed below:
The duration of a degree course is usually 3 to 4 years and the emphasis is on academics, whereas a Diploma course is a short term course (usually 1 to 2 years in duration) that focuses on training a person in a particular field.
An institute, a Polytechnic, or even a university can offer a Diploma course. There is no need for the institute or the university to be UGC or AICTE approved. Only a university can confer a degree. To pursue higher education, only a degree from a UGC-approved university is accepted. AICTE-approved private institutes are affiliated to UGC-approved universities. In case a person graduates from an AICTE approved private institute affiliated to a UGC approved university, he still gets the degree of the university.
A person must have successfully passed the 12th standard to pursue a Bachelors degree. One must possess a Bachelor's degree to pursue a master's degree. A person can enroll for a Diploma course even after class 10. There are Diploma courses that require the candidate to be an HSC pass-out. Diploma courses at the Masters level require the candidate to have a graduate degree. Regards.
