Cyber forensics is mainly concerned with the investigation and recovery of data and information found on devices such as phones and computers. It is used by people not only for legal purposes but for personal use as well especially when there’s a breach of information involved. Since we are mostly reliant now on computer systems, networks, and the cloud, cyber forensics is already an important aspect of running a business or a company.
Cyber forensics can also be referred to as digital forensics and has a lot of purposes such as support for criminal or civil cases, boosting cyber security, incident response, and many more. With the increased digitalization we have nowadays, many-branched of cyber forensics are also created. Here are the different branches of cyber forensics and their purpose.
Computer forensics is a branch of cyber forensics that mainly concerns gathering and investigating information from computers and other digital data storage media. Whether you have a problem with lost data or an information breach in your computer, a computer forensic investigation is what you need. You can be sure that all the information and digital evidence are sourced safely and legally when you hire a computer forensic investigator to do the job.
Mobile Device Forensics
The use of mobile devices has skyrocketed since the advent of smartphones. Today, almost everyone owns a smartphone, no matter what the age is. It is used by people for a variety of purposes – from communication, learning, shopping, entertainment, and many more.
Since mobile devices work a lot different than computers, they have created a different branch of cyber forensics for it – mobile device forensics. Investigators in this branch undergo extensive training since it requires a lot of tools and methods to extract information from mobile devices efficiently and in a legally sound way.
Unlike computer and mobile device forensics, network forensics requires a more proactive type of investigation. The main purpose of this branch is to monitor and analyse network traffic. With this monitoring, the analyst should be able to detect intrusions and gather the needed information and evidence for legal purposes. Network forensics can also be used to capture network traffic during a cybercrime investigation.
As the name suggests, this branch of cyber forensics deals with databases and the related metadata on them. Timestamps are created when someone updates any content of the database. These timestamps are examined and tested whether they are valid to verify all the actions done on them.
Database forensics can also be used to gather evidence and track malicious activities such as fraud and theft. Database forensics works a lot different compared to the previous three branches and requires different training to become a good analyst.
Cyber forensics is an essential part of our lives these days, especially now that we are living in a more digitalized world where information can be accessed and even stolen from us so easily.
