Frequently Asked Questions on Cyber Forensics
What is live analysis, and how does it aid in cyber forensic investigations?
The operating system does live analysis while the computer or device is in use. Typically, volatile data is kept in RAM or cache, and it is located, analyzed, and extracted using system tools to effectively preserve the chain of custody of evidence. Live analysis helps investigators gather and examine the information that is collected from the installed software programs and hardware details, which is essential for forensic analysis and legal proceedings.
How does reverse steganography contribute to cyber forensic investigations?
It is a technique where cybercriminals utilize steganography as a strategy to hide data from digital files, messages, and data streams. In reverse steganography, the data hashing inside a particular file is examined. Hidden information in a digital file or image can not appear suspicious when examined. This technique is crucial for cyber forensic investigators to detect concealed data within files, or data streams, providing information related to potential cyber threats or criminal activities.
How does Cross-drive analysis (CDA) help the investigation process in cyber forensics?
Cross-drive analysis helps identify commonalities and suspicious occurrences by correlating and cross-referencing data from multiple computer drives, enabling the identification and examination of relevant data that is pertinent to cyber forensic investigations.
Techniques of Cyber Forensics
Digital Forensics, or Computer Forensics, is the applied scientific methodology and procedures in identifying, collecting, protecting, examining, presenting, and legally preserving digital evidence in any other discipline. The initial stage in this procedure is to distinguish, capture, and retrieve digital proof from various sources, comprising computer systems, mobile devices, computer networks, and digital storage media.
The main focus of the discipline is to develop evidence from digital systems and software to determine probable complex models or insights about the existence or occurrence of illegal cyber actions that have harmed the safety and security of a digital environment. The article will provide insights into the different techniques applied in cyber forensics.
