What Is Data Forensics?

Forensics is the science of investigating something that has happened in the past. Data is the oil that keeps organizations running. Bring the two together, and you find data forensics. It studies data in depth and in detail to squeeze any ounce of information from it. Yet a more detailed explanation is provided further. Read on! You know the ancient saying: "A picture is worth a thousand words." Well, data forensics is worth more than a million. Data forensics, often used interchangeably with computer forensics, is the study of digital data and how it is created and used for an investigation. Data forensics is part of the greater discipline of forensics, in which various types of evidence are studied to investigate an alleged crime. What does that mean? Essentially, if you're looking into something like a hack, spying scandal, or even just trying to figure out whether someone's been snooping around your computer, you need to know who did it and what they did. That's where data forensics comes in handy! Data forensics is tricky. It's all about collecting data, but it can take time to tell what kind of data you want. There are two types of data: persistent and volatile. Continuous data is stored permanently on your hard drive, so it's easier to find and analyze than volatile data, which is more elusive and takes more time to understand. If you're doing data forensics on persistent data, it's clear that you know where and how to access the evidence. If you're looking at volatile data that has become difficult to recover or analyze (like a virus), you'll have to do some serious digging before finding what you need. Forensic analysts sometimes even focus on persistent data that is easy to come by but must be assessed in-depth to prove criminal intent!
