Digital Forensics – an Understanding in Today’s Business World
Digital forensics is the recovery and investigation of digital data from organised businesses where computer systems have failed.
It can also be used as a tool to track cyber crime or as a way of understanding the process of the preservation and investigation of electronic data within a company’s computer data infrastructure. Furthermore, the term applies to the retention of evidence for legal purposes from digital data which has been recovered from a company’s computer systems.
The term digital forensics relates mainly to the area of cybercrime where clients need specialised help to resolve a particular problem. In the modern era, the rapid advancement of computers and systems has grown considerably and this in turn has led to more calculated and manipulative cyberattacks requiring an extremely high level of technical assistance. However, digital forensics does not solely concern cybercrime; it covers all aspects of digital data loss. This can also entail the recovery of data which has been accidentally deleted or where computer failures have happened due to human error. The phrase digital forensics has a broad terminology, however its main purpose is to organise or give evidence that will help clients better understand what has gone wrong within their company or what needs to be done to organise the digital infrastructure within the company so the incident does not happen again.
In the modern digital age, digital forensics is an advanced form of policing for companies. As all digital data leaves a footprint, digital forensic specialists can detect past data and investigate why a computer system has failed. It determines why a digital incident has happened and evaluates the best way to move forward. It also looks at the recovery of lost data where possible. Digital forensics is used for information management where data is organised in many forms, for example: network packets, AFF files, individual disk drives and extendable file platforms for the purpose of storing and sharing different forms of evidence.
The definition of digital forensics can contradict itself, as the author Eoghan Casey suggests in his book, Digital Evidence and Computer Crime 2nd Edition. The writer presents an inaccuracy in the terminology with regards to the different names it has been given, such as digital forensic science, forensic computer analysis, digital evidence examination and computer analysis. However, the subject of digital forensics is very important in the modern world and within business. For example, recently there have been cyberattacks on security teams within companies that were using out-of-date platforms such as those that rely on technology which uses signatures. These systems may be good at preventing basic malware, but they are not sophisticated and vigorous enough to handle the kind of cyberattacks currently happening across different platforms within the corporate world. This is a growing problem facing governments and businesses today.
Digital forensics depends upon the management of different pieces of digital evidence, evaluated by a team who review the evidence several times using tools which can locate where something has gone wrong or where a crime has been committed. It is also used in the fields of terrorism and personal data crime. These are just some of the fields someone could be working in as part of a career in digital forensics. More and more businesses are turning towards using digital equipment, so with this in mind, digital forensics is a very good choice to make for somebody thinking about pursuing a career in this direction.
