Cyber Forensics: The Key to Solving Cybercrime
Cyber forensics is a critical process that involves the extraction, collection, processing, analysis, and reporting of digital data in a legally authorized manner. It is also commonly referred to as computer forensics. Digital forensic analysis systematically investigates a device, system, network communication, or memory image. The procedure involves analyzing Electronically Stored Information (ESI) on electronic devices such as desktop computers, laptops, and external hard drives. The primary focus of cyber forensics is to detect and prevent cybercrime while ensuring that any evidence is maintained digitally.
The Role of Cyber Forensics in the Legal System
Forensic investigators employ specialized procedures when they locate and present evidence in a court of law. They use a methodical technique to verify factual facts in both civil and criminal cases. The purpose of cyber forensics in solving cybersecurity incidents is to answer questions depending on the type of analysis required. Furthermore, cyber forensic experts are responsible for conducting a thorough investigation and analysis of digital evidence, which may be used in legal proceedings.
The Importance of Staying Up-to-Date
It is important to note that cyber forensics is an ever-evolving field due to the rapid advancement of technology. Forensic investigators must continuously update their knowledge and skills to keep up with the latest trends and developments. They must also adapt to new challenges and threats posed by cybercriminals.
Applications of Cyber Forensics
Cyber forensics has many applications in commercial, civil, and criminal investigations. Some examples of investigations where cyber forensics may be used include:
- Intellectual property theft
- Indecent imagery investigations
- Employment disputes
- Fraud investigations
- Bankruptcy investigations
- Regulatory compliance
- Litigation and dispute resolution
In each case, cyber forensic experts must carefully analyze digital evidence to establish facts that are admissible in court. This process requires specialized knowledge and skills in the field of cyber forensics, as well as an understanding of the legal system and the rules of evidence.
The Digital Forensic Analysis Process
The digital forensic analysis consists of the following three phases:
- Obtaining digital evidence During this phase, investigators must ensure that they obtain a precise copy of the data from the original media to avoid discrepancies that can affect the authenticity of the evidence.
- Analyzing the digital evidence During this phase, investigators must ensure the integrity of the evidence. The acquired evidence must remain the same over time, and any changes must be discoverable to maintain the credibility of the evidence.
- Creating a report/briefing or expert’s report for judicial proceedings During this phase, investigators must ensure that the acquired evidence comes from the analyzed device/system/source in a set period to ensure authenticity. The report should be presented in a manner that is easy to understand and should include details of the analysis performed, findings, and conclusions. This report may be used in legal proceedings to establish admissible facts in court.
Retrieving Evidence
Cyber forensics is required for crime detection and prevention. It allows investigators to examine a crime scene that is linked to any digital evidence and facilitates the recovery of files that have been encrypted, erased, or corrupted. Cyber forensics experts search for and detect cybercrime-related data in any digital asset. If digital evidence is not handled correctly, it can be easily deleted.
The primary objectives of cyber security forensics investigators are to retrieve, analyze, report, and present computer-oriented documents so that they may be easily demonstrated and submitted as evidence in a court of law. In addition, they aim to discover evidence promptly, quantify the total threat and impact of the malicious cyber activity on the affected user or business, and provide remedies.
The evidence that cyber forensic experts can retrieve includes:
- Email correspondence, including deleted emails
- Internet activity, history, account information, and downloads
- Stolen electronic data/intellectual property
- Deleted files, folders, images, and videos
- Operating data, including creation times, dates, and system logs
In conclusion, cyber forensics is essential to maintaining digital security and investigating cybercrime. Its applications in commercial, civil, and criminal investigations are numerous, and its systematic approach to collecting and analyzing digital evidence ensures that the facts are presented accurately in court. Cyber forensic experts play an essential role in the administration of justice, and their specialized knowledge and skills are crucial in identifying and prosecuting cybercriminals.
