Digital forensics is one of the newer branches of forensic science. It deals with the investigation of material on digital devices. Owing to the fast-growing trends in the digital world, digital forensics has become one of the most used and most beneficial branches of investigation science. But what does it really do and how does it help people or companies? Keep reading to find out.
What It Is?
Forensics refers to the techniques used to detect crimes. When it comes to digital forensics, this means the finding of evidence from digital media devices. This is especially useful in cases where digital media is used for crimes, or in other words, it is the best technique that can be used to find evidence in computer crime.
Types of Digital Forensics
There are many sub-branches of digital forensics that deal with different areas of digital technology. For example, disk forensics involves the retrieval and extraction of data from active, modified, or deleted files. Network forensics on the other hand is related to the analysis of computer networks to collect evidence that can be used in a case. Database forensics refers to the analysis of databases for information extraction.
Another sub-category is mobile forensics where the information on mobile devices – from call logs to saved media is examined. In addition to these, there are also malware forensics, email forensics, and memory forensics. Each of these types refers to different specialised categories of forensics that examine digital devices and cyberspaces for gathering information relevant to various illegal activities.
How Can It Help You?
A downside to the dissemination of technological knowledge is that it is not only used for good purposes. And when it is being used for illicit activities, you need people specialised in that technology to solve such crimes.
For example, this branch of forensics helps to find the evidence recorded in digital devices to be produced in courts. This is especially useful in cases where cyber security is threatened or compromised. As a result, it has become easier to track and locate cybercriminals from anywhere in the world.
For companies that use computer networks and large databases for their communication and information storage, this also helps to achieve computer system security. In the long run, you will be saving your money that would have been lost in lawsuits or to the hands of cybercriminals.
There are many ways in which digital forensics helps save businesses, especially large companies and organisations. This technique is used in cases that are related to intellectual property theft, industrial espionage, employment disputes, fraud investigations, inappropriate use of the internet and emails at work, forgeries, and bankruptcy.
For those involved in the business world, this is the next step in ensuring the safety and security of the employees, clients, and the valuable information that is saved on the company devices. Digital forensics will help you to keep clear of financial losses and information breaches and save the integrity and reputation of the company.
