 So this week we're going to be talking about research in digital forensic investigations. In my opinion this is probably one of the most important aspects of digital forensic investigations is being able to keep up on research. The reason for that is just because technology changes so fast, investigators that are doing investigations full time often get new technologies in that have been used in some sort of crime and normally the investigators have to spend quite a bit of time doing research on how those technologies work and again like we were doing before trying to figure out what user activities or how to extract user activities or user information from those devices, how to get metadata, how to create timelines. So it's very important for investigators to be able to do research not only on technical topics but also just to know where digital forensics is going, where cyber crime is going to and to keep updated on the different types of cyber crimes. So what we're talking about this week is essentially how to do research, how to stay up to date on these topics and the best way you can possibly do that is get used to reading academic journal articles. Academics that are producing a lot of articles are normally focusing quite a bit on the technologies that are relevant right now. So academics and investigators work together in most countries usually quite well to say we are currently having this particular problem and then academics will normally look at that problem and find solutions for the investigators and then they tend to publish papers on how to do certain types of investigations, how to analyze certain data sources. So that cooperation and that publication process is really helpful to other investigators as well. So while you're doing digital forensics and cyber crime investigations make sure that you're accessing academic articles and keeping up to date on what's going on in the field. Again, not only for the technical aspects but also for kind of policies that are going on, new standards that are coming up, new ways to verify data or analyze data, new approaches to management of digital forensics laboratories, a lot of issues that organizations tend to have isn't necessarily that they don't have technical people or technical knowledge but just that the management process isn't streamlined. So they still have a lot of backlogs or a lot of issues because the management parts of the investigation isn't done well. So this is a way to learn a little bit about every aspect of investigation, management of the investigations, management of victims, management of suspects, all of these different aspects are normally published in a lot of different, usually academic journals but also books. So the resources that I'm recommending for you this week, I'll give you links to forums where both academics and industry leaders and digital forensic investigators, cyber crime investigators from all over the world tend to go. Most of these forums are in English but I will post some links to some Korean forums as well. I'll also recommend some books and some publishers that normally produce some very good relatively new kind of how-to manuals as well as general guides on how to do investigations. I'll also post links to other governments and their guides on how to do investigations and I will make some journal recommendations of journals that I believe are the best that you should be looking into at least regularly. So basically this week I'm going to be giving you a lot of resources for you to go through and hopefully get you used to the research process, this part of this. Most of the cyber crime investigators that I work with spend at least one hour a day researching some sort of new topic that's related to their case. Now most of that research is very, very technical but that still means that a large part of their job is research. So if you know how to research well and you know how to organize the research that you've done and especially share the research that you've done, not only will you be better at digital investigations and cyber crime investigations but you'll also be able to help your colleagues a lot more. So that's it for this week and thank you very much.
