Represent Forensics with The Cyber World
Best Engineering college in Jaipur Rajasthan have many courses like Cyber forensics work is to extracting data as proof of a crime (that involves electronic devices) while following proper investigation rules to nab the culprit by presenting the evidence to the court. Its work is to maintain the thread of evidence and documentation to find out who did the crime digitally. Cyber forensics can do the following:
- Recover deleted SMS, Phone calls, chat, emails, files
- Recover recorded audio of phone conversations.
- It can check which user used which system and for how much time.
- It can check which user ran which program.
Why Is Cyber Forensics Important?
- It gives forensic cover for quicker investigations and accurate results.
- This Equipment stores massive amounts of data that a normal person fails to see.
- It gives helps innocent people to prove their innocence via the evidence collected online.
- It solves digital crimes and also solves real-world crimes like theft cases, murder, etc.
- For businesses also cyber forensics in tracking system breaches and finding the attackers
The Process Involved in Cyber Forensics
- Obtaining a digital copy of the system that is being or is required to be inspected.
- Authenticating and verifying the reproduction.
- Recovering deleted files (using Autopsy Tool).
- Using keywords to find the information you need.
- Establishing a technical report.
How Did Cyber Forensics Experts Work?
For Top Collages of Engineering of Rajasthan also need these experts to protect their data, Some other procedures are:-
Identification: It is to identify what evidence is present, where it is stored, and in which format it is stored.
Preservation: Then next is to safely preserve the data and not allow other people to use that device so that no one can tamper with data.
Analysis: After that analyze the data or system the expert recovers the deleted files and verifies the recovered data and finds the evidence that the criminal tried to erase by deleting secret files.
Documentation: Then record contains all the recovered and available(not deleted) data which helps in recreating the crime scene and reviewing it.
Presentation: In last which the analyzed data is presented in front of the court to solve cases.
Types Of Computer Forensics
Network forensics: It monitors and analyzes the network traffic to and from the criminal’s network also used for network intrusion detection systems and other automated tools.
Email forensics: In this, the experts check the email of the criminal and recover deleted email threads to extract crucial information related to the case.
Malware forensics: It involves hacking-related crimes. Some forensics expert examines the malware, and trojans to identify the hacker involved behind this.
Memory forensics: It deals with collecting data from the memory(like cache, RAM, etc.) in raw and then retrieving information from that data.
Mobile Phone forensics: This generally deals with mobile phones.
Database forensics: It examines and analyzes the data from databases and their related metadata.
Disk forensics: This extracts data from storage media by searching modified, active, or deleted files.
Techniques That Cyber Forensic Investigators Use
Reverse steganography: This method of hiding important data inside the digital file, image, etc.
Stochastic forensics: In this experts analyze and reconstruct digital activity without using digital artifacts.
Cross-drive analysis: When the information found on multiple computer drives is correlated and cross-references to analyze and preserve information that is relevant to the investigation.
Live analysis: When the computer of criminals is analyzed from within the OS in running mode.
Deleted file recovery: It is searching for memory to find fragments of a partially deleted file to recover it for evidence purposes.
Advantages
- Because of this many people, companies, etc get to know about such crimes, thus taking proper measures to avoid them.
- It finds evidence from digital devices and then presents them in court, which can lead to the punishment of the culprit.
- They track down the culprit anywhere in the world.
- It helps people or organizations to protect their money and time.
Criminal Prosecutors – They rely on evidence obtained from a computer to prosecute suspects and use it as evidence
Civil Litigations – They discovered Personal and business data on a computer can be used in fraud, divorce, harassment, or discrimination cases
Insurance Companies – The Evidence discovered on the computer can be used to mollify costs (fraud, worker’s compensation, arson, etc)
Private Corporations – They can obtain evidence from employee computers that can be used as evidence in harassment, fraud, and embezzlement cases
Law Enforcement Officials – They rely on computer forensics to backup search warrants and post-seizure handling
Individual/Private Citizens - When Obtaining the services of professional computer forensic specialists to support claims of harassment, abuse, or wrongful termination from employment
Computer Forensics Services: Comparison, Transaction sequencing, Extraction of data, Recovering deleted data files, Format conversion, Keyword searching, Decrypting passwords, Analysing and comparing limited source code
Conclusion
Best Private Engineering College in Jaipur Rajasthan says It is based on technology and knowledge of various technologies, computers, mobile phones, network hacks, security breaches, etc. is required. It should be very attentive while examining a large amount of data to identify proof/evidence. Expert must be aware of criminal laws, criminal investigation, etc. They must be able to analyze the data, derive conclusions from it and make proper interpretations. Important is communication skills of the expert must be good so that while presenting evidence in front of the court, everyone understands each detail with clarity. They should have strong knowledge of basic cyber security.
