Enterprise Security Magazine | Thursday, December 30, 2021

Digital forensics is a rapidly expanding scientific field. It also changes in reaction to the rapid advancement of technology.

Fremont, CA: The word digital forensics comes from the umbrella term computer forensics. It is now a distinct applied discipline devoted to the investigation of computer-related crimes, as well as ways for locating, collecting, and securing digital evidence. Any data found on digital devices are dealt with by digital forensics. Digital forensics has progressed from unstructured operations primarily carried out by hobbyists to a well-organized, recognized applied discipline that identifies, evaluates, and retains all data on digital devices.

The examination and investigation of events involving computer information as the target of an attack, a computer as a tool for committing a crime, and gathering, storing, and protecting any digital evidence are the core applications of forensics. The expert analysis' findings are utilized in court to either support or refute a hypothesis.

Some types of forensics are:

Network forensics

The goal of network forensics is to track, record, and analyze all network activity. In the event of security breaches, cyberattacks, or other cyber incidents, network specialists examine traffic and activities.

Computer forensics

Data from personal computers, laptops, and storage computing devices is collected, identified, preserved, and analyzed in computer forensics. Computer forensics experts are usually involved in investigations of computer crimes, although their services are also required in civil lawsuits and the data recovery process.

database forensics

Database forensic experts look into any database access and report any changes to the data. Database forensics can be used to investigate large-scale financial crimes and verify business contracts.

Email forensics

Analysts that specialize in email forensics extract valuable information from emails. The identities of the senders and receivers, the content of the messages, time stamps, sources, and metadata are all examples of this information. When a corporation is suspected of email forgeries, email forensics techniques are commonly used.

Mobile device forensics

Data can be recovered from smartphones, SIM cards, mobile phones, GPS devices, tablets, PDAs, and gaming consoles by specialists in this sector. This type of analysis is needed to recover audio and visual data, contacts, and call logs from devices used as evidence in court.
