Digital forensics is a branch of forensic science focused on identifying, preserving, analyzing, and documenting digital evidence from devices like computers, phones, and networks to reconstruct cybercrimes or support legal proceedings. It acts as a “cyber detective” role, crucial for investigating data breaches, fraud, and theft, often referred to as computer forensics or cyber forensic investigation.
What is Digital Forensics? Let’s address one of the most commonly asked queries. Today, the world is highly interconnected through instant messages and transactions, highlighting the presence of digital footprints. Digital forensics simply refers to the science of identifying, collecting, analyzing, and documenting digital evidence. In the event of cybercrimes, data breaches, online scams, or corporate conflicts, the underlying foundation is nothing but digital forensics. They do the investigation and serve justice. Digital forensics has evolved rapidly with the rise of cybercrimes. According to global reports by Ventures, globally, cybercrime numbers are expected to cross $10.5 trillion per year by 2026. This makes digital investigations more critical. It helps not only to track hacked systems but also to recover data, as digital forensics plays a vital role in both criminal and civil cases.
As digital forensics tools are being used worldwide, the requirements for skilled digital forensics professionals are rising. So digital forensics is not just technical but also analytical.
What is Digital Forensics?
Digital forensics refers to a branch of forensic science that is based on scientifically recognizing, collecting, preserving, analyzing, and presenting digital evidence. This is used to support criminal investigations and to give any type of cybercrime response. It helps civil conflicts, making sure the data’s integrity is legally verified. Cybersecurity teams can use digital forensics to identify the cybercriminals behind a malware attack, while law enforcement agencies can use it to analyze data from a murder suspect’s device. Many people confuse cyber forensics with digital forensics, which is not right. Cyber forensics deals with internet or network-related crimes. While digital forensics deals in a broader sense with devices.
Types of Digital Forensics
There are various types of digital forensics. So, to help you understand each one of them is important.
| Forensic type | How it works investigation |
| Computer forensics | Data from laptops, computers, storage, and hard drives. |
| Mobile device forensics | Messages, photos, apps, sim cards. |
| Network forensics | Network traffic, security breaches, and malwares |
| Cloud forensics | Data that is stored in cloud storage or services like AWS. |

How Digital Forensics Works
Digital forensics is a scientific process and involves various stages. The first stage among the five core stages is identification and collection, which involves experts securing devices to prevent data tampering. Then next is preservation of original devices securely, as analysis is based on the copy to maintain data integrity. The third stage is examination and analysis. This is where the investigators use special tools like Encase or FTK. This involves recovering data, examining system logs, and analyzing hidden data. The last stage is reporting and presenting. This means you synthesised the findings into a brief report for legal proceedings.
