What Is Forensic Data?
This is mainly known as Computer forensics, and it is basically the study of or investigation of digital data and how it is created and used simultaneously. Data forensic is one of the more significant disciplines within forensics, where the forensics data storage is protected, and the data is later used to conduct investigations and alleged crime.
There is a vast difference between data recovery and computer forensics; what usually brings the difference is the intended purpose of the recovery and how the data is going to be used. Computer forensics is the recovery or finding of data on a computer system or piece of hardware for use in law enforcement or a particular criminal investigation. But for the case of data recovery is just the act of looking at data which lost or damaged and restore it to its normal or usable state. However, data recovery and computer forensics have the same similar procedure in accruing the data.
Data forensics ordinarily involves tracking phone calls, email, and texts or even going through the network. The digital forensics experts may employ decryption, advanced system searches, and other top-ranked analysis in their data forensics process. There are two types of data usually collected in data forensics, permanently stored in forensic data storage gadgets. This makes it easy to find, known as persisted data, and the other one is called volatile data. Volatile data is impermanent elusive data, and this gives this data a feature of being difficult to recover and analyze.
The process involved in Data Forensics
The process employed by data forensics is in 4 categories: acquisition, examination, analysis, and reporting; besides, other various techniques are utilized in investigations. One of the techniques employed is cross-drive analysis, this links information discovered on multiple hard drives. Another technique utilized is live analysis; this analyses the computer operating system using custom forensics to get real-time evidence. The third technique used is the recovery of deleted files and information.
Why Did Data Forensics Come into Existence?
As the use of current technology rapidly increased, which was evident by using computers in the 1980s, numerous crimes also became a significant issue, for instance, cybercrimes. The remedy for the emerging crimes, data forensics, was developed and used to investigate and come with evidence used in court. This is a clear indication that forensic data must produce evidence that is admissible, realistic, and reliably obtained. Apart from cybercrimes, other crimes which were being investigated are cyber stalking, fraud, data theft, espionage, and many more.
Tools and software used by Data Forensics
Honestly, there is numerous data forensic software available, and they provide their own data forensic tools for recovering or dislodging deleted data. Security software such as endpoint detection, data loss prevention software, and many more came along with monitoring and logging tools for data forensic as part of a more comprehensive data security solution.
There are numerous challenges facing data forensics. This can be categorized into three types that is technical, legal, and administrative. Technical factors include consumption of device space, issues with encryption, and anti-forensics methods.
