David Teo’s TedTalk speech on his experiences as a digital forensics investigator was very informative.  As he stated in his introduction, most people usually are confused by what exactly that is.  Which I surely was. 

His upbringing as an accountant and working IT allowed him to gain access to knowledge and experience for his upcoming job as a digital forensic investigator.  In social science, we learned about Privacy Rights, as well as the role of  Cyber offending motives. Through personal ethics, these experts are able to get hidden/deleted information by doing in depth searches online. Understanding these motives and human behavior allows them to make the best decision for their digging.  As Teo explained, they go looking for deleted files and materials as evidence.  Since this is where the good stuff is usually stored.  I believe that this job plays an important role in our society, as it helps limit crime online and allows companies to save their business from outside and insider threats.
