In David Teo’s TEDtalk, he talks about how back then the career of digital forensics did not have college courses. In order to get into this specific field you had to fall into it with another field, in which David fell into the field of digital forensics through accounting and his father also told him about the field as well. This gives a time period of how technology wasn’t advanced back then and people weren’t aware of cybercrimes. Also, it show that back then the field was expanding like how the cybersecurity field is expanding today and is in demand for more cybersecurity employees and experts.
