Computer Forensics guide for Beginners
Since Internet has evolved as the main source of communication there raised many criminal minds to spread their tentacles. Just as forensic studies are associated with scientific tests by police in solving crime cases, computer forensics is a detailed and scientific study in investigation of computer science cases to gather digital proof in cyber crimes.
The main objective of computer forensic professionals is not only tracing the culprit but also find out the proof and present the facts against culprit in a legal action. There are only few areas of crime where computer forensics cannot be used. But Law enforcement agencies uses computer forensics to greater extent and are in the first position in the development of computer forensic field.
Computer forensics constitute in hacking the cyber crime that may hold proof in the form of emails related to crimes such as kidnap, murder, illegal use of computer by stealing password and username, releasing viruses into computers, fraud and drug trafficking or in bomb blasting attacks with meta-data that are associated with files and documents make investigators to proceed with their further investigation.
A computer forensic examination discloses when a document first appeared on a computer, the last date when it was modified, the time when it was saved and printed by which user. There are various tools utilised in computer forensics such as Packet sniffers, Hex editors, Disk analyzers and Disassemblers are Custom made software used for these crime purposes.
The computer forensics is such a field which should be very confidential to the greatest value coming future to counter the rise of cyber crimes. Since it is a brand new regulation which is no yet recognized as a formal scientific discipline. so there is a lack of standardization and consistency in courts and forensic agencies. But hope that improved personal computer and network protection computer forensics will develop to serve as a threat against individuals with negative and criminal mind sets.
There are few procedures used in computer forensic method:
We can recovery the deleted files since most operating systems don’t delete physical file data. Files can be recovered together by using particular tools and skills.
Through packet sniffing data like login data to emails that flows through the network lines are pulled out from these networks called as packet sniffing.
An IP Address can be traced by computer forensics. Steganography which is hiding of information in the format of sound, pictures or any other form can be extracted through different decryption strategies to its original form.
With the help of scrutinized data stored in tough disks, volatile memory RAM or ROM can be and searched and revealed in computer forensics.
As the computing is increasing in each and every field with increase in new technology in operating systems, hardware and software No one computer forensic examiner need to become expert on all fields since they come across with unexpected tasks and analyze the situation before by experimenting such new technologies.
