What is the definition of cyber forensics?
Computer forensics or cyber forensics is the practice of utilizing investigation and analytical techniques to obtain and preserve evidence. It is done via a specific computing device in a manner acceptable for presentation in a court of law.

If you learn digital forensics, the objective is to conduct a structured investigation and maintain a recorded chain of evidence. It is done in order to determine precisely what occurred on a computing device and who was accountable.
Computer forensics – sometimes referred to as computer forensic science or cyber forensics – is essentially data recovery with legal compliance rules in place to ensure that the material is admissible in court. Digital forensics and cyber forensics are frequently used interchangeably with computer forensics.
- Digital forensics begins with the collecting of data in a secure manner.
- The data or system is then analyzed to discover if it was altered, how it was altered, and who altered it.
Computer forensics is not usually used in connection with a crime.
When is computer forensics used, and how is it used?
There are few areas of a criminal investigation or civil litigation where computer forensics cannot be used. Law enforcement agencies were among the first and most prominent users of computer forensics, and as a result, they have frequently been on the cutting edge of field innovations.
Computers can be regarded as a ‘crime scene’ due to hacking and denial of service assaults, for example. They may contain evidence of crimes committed elsewhere, such as emails, internet history, documents, or other data pertaining to murder, kidnapping, fraud, or drug trafficking.

A forensic computer examination may disclose significantly more than anticipated.
Computer forensic investigators are interested not just in the content of emails, documents, and other files but also in their metadata. Metadata gives additional information on a particular dataset, which can be illuminating in and of itself.
Commercial organizations have sought the assistance of computer forensics in a variety of situations, including:
- Theft of intellectual property.
- Employment conflicts.
- Invoice fraud is frequently facilitated by phishing emails.
- Use of email and the internet inappropriately in the workplace.
- Compliance with applicable regulations.
What is the significance of cyber forensics?
- Cyber forensics assists the civil and criminal justice systems in ensuring the integrity of digital evidence presented in court cases. As computers and other data-collection devices become more prevalent in all aspects of life, virtual evidence.
- The ordinary person never sees a large portion of the data collected by current devices. For example, without the driver’s knowledge, automobile apps continuously collect data on when the driver brakes, switches, and changes speed. This information might be essential in resolving a legal matter or a crime, and cyber forensics is often used to find and preserve this data.
- It can also be utilized to solve crimes committed in the physical world, such as burglary, assault, hit-and-run accidents, and murder.
- To safeguard sensitive information, businesses frequently employ a multilayered data management, data governance, and network security strategy.
- Businesses utilise cyber forensics to track information about a compromised system or network, which can be used to identify and prosecute cybercriminals.
- Additionally, businesses can leverage digital forensic expertise and methods to aid in data recovery following a system or network failure caused by accident.

Computer forensics techniques
Computer forensic examinations come in a variety of forms. Each one focuses on a different component of information technology. Several of the most prevalent varieties are as follows:
- Forensics of databases: The investigation of data and associated metadata included in databases.
- Forensics of email: Recovering and analysing emails and other data stored in email services, such as schedules and contacts.
- Forensics of malware: Sifting through code to find and analyse possible dangerous applications. Trojan horses, ransomware, and different viruses are examples of such programmes.
- Forensic memory analysis: Collecting data from the random-access memory (RAM) and cache of a computer.
- Forensics mobile: Examining mobile devices in order to access and analyse the data contained therein, which may include contacts, incoming and outgoing text messages, images, and video files.
- Forensics network: Monitoring network traffic with technologies such as a firewall or intrusion detection system to look for evidence.
What role does computer forensics play in the courtroom?
Since the 1980s, law enforcement agencies and courts have used computer forensics as evidence in criminal and civil cases. Several noteworthy instances include the following:
- Theft of Apple trade secrets
Xiaolang Zhang, an engineer in Apple’s autonomous vehicle group, announced his retirement and stated that he would return to China to care for his elderly mother. He informed his management of his intention to work for a Chinese electronic car firm, arousing suspicion.
According to an FBI document, Apple’s security team investigated Zhang’s network activity and discovered that he downloaded trade secrets from confidential business databases to which he had access in the days preceding his resignation. In2018, the FBI indicted him.
In one of the most frequently mentioned accounting fraud scandals, Enron, a United States-based energy, commodities, and services corporation, erroneously reported billions of dollars in sales before declaring bankruptcy in 2001, causing financial hardship to a large number of employees and other investors.
Careers and certifications in cyber forensics
Computer forensics has developed into a distinct field of scientific study, complete with training and certification. The following are only a few examples of cyber forensic job paths:
- Engineer specialising in forensic science: These specialists are responsible for the data collection step of the computer forensic process, which include acquiring and preparing data for analysis. They aid in determining the cause of a device’s failure.
- Accountant forensic: This role is responsible for enforcing laws relating to money laundering and other transactions used to conceal unlawful behaviour.
Computer forensic professionals must have a bachelor’s degree – and, in certain cases, a master’s degree – in computer science, cybersecurity, or a related discipline.
Job description for a cyber forensic expert
Digital forensics professionals’ precise tasks will vary greatly based on the employer’s objective and the nature of the case at hand. Tasks could involve any or all of the following:
- Utilise industry-leading forensic tools to detect, collect, preserve, and analyse electronic data from laptops, desktops, servers, backup tapes, cell phones, and PDAs, among other media.
- Recover deleted user data, hidden data, file fragments, and temporary files.
- Electronic evidence management and tracking.
- Identify and document an attacker’s tactics, techniques, and procedures for gaining illegal access.
- Create and distribute engagement reports, technical reports, and briefs that summarise analytic findings.
- When photographing, archiving, shipping, and handling electronic data and associated physical devices, adhere to industry-standard forensic best practices.
- Testify as an expert witness.
The Future of digital forensics
For the foreseeable future, information security specialists will be in high and rapidly expanding demand. Thus, doing an online cyber forensics course can be very beneficial for your career.
In India, the average gross income for a computer forensic investigator is 6,18,846 rupees, or Rs. 298 per hour. Additionally, they receive an average bonus of Rs.11,572.
As networks, applications, and information requirements become increasingly complex and vital to commercial and government operations, these systems become more directly targeted and vulnerable.
Almost any type of corporation needs digital forensics expertise. By scanning job postings, one might discover opportunities at a variety of different types of businesses, and the larger the business, the more experts it is likely to require.
