Technology advancements have transformed the field of Forensic Science. Initially, forensic experts were only focused on gathering physical evidence from hand-written copies of papers, printed and faxed messages.
However, with the introduction of computers, new digital evidence have been introduced. Computer and mobile devices store information and data in their memory even after everything has been erased. As a result, gathering digital evidence has shifted from the normal analysis of hardcopies to analysis of computer and mobile phones to gather evidence in case of a crime.
As a digital forensics student, you are required to handle regular research papers and case studies that might involve computer or mobile phone forensic analysis. At kaliPapers, we understand the struggles involved and that is why our experts are ready to offer quality digital forensics assignment help.
Digital forensics involves the preservation, identification, extraction and recording of digital evidence from computers to be utilized as evidence in a court of law.
Digital forensics is a science applied in gathering evidence from digital media like computers, network devices, servers and mobile phones. As a digital expert, you are responsible analysing, inspecting and preserving the physical and digital evidence contained in any electronic device found on the crime scene.
Digital forensics is a crucial course that helps law enforcement authorities in putting the bad guys behind bars. So as a student you might be wondering, why should I study digital forensics? Here are few reasons why you should study digital forensics:
As an investigator or a digital forensic expert, you are supposed to follow a specific process and procedure to ensure that the gathered evidence is admissible in a court of law.
Through the Forensic Tool Testing (CFTT) project, the National Institute of Standards and Technology (NIST) recommended a five step digital forensics process.
Identification involves conducting preliminary analysis of the crime scene to determine where the evidence is, where it is stored, the devices used for storage and the storage format. Data collection should be conducted immediately to avoid tampering or loss of data.
After collecting the data, digital forensic experts should examine the collected data with the use of both manual and automated tools such as Encase, SleuthKit (Autopsy), and Volatility Framework among others.
After examining the devices, the results and artefacts should be well examined to eliminate false positives and extract the actual evidence related to the case at hand.
The final digital forensics process involves documentation. The final digital forensics report should contain the actions executed, an explanation of tools and procedures employed to gather and analyse evidence, the process of gathering and securing the evidence and the person responsible for the whole process. Finally the report should include recommendations on how the organizations can secure its resources.
Digital forensics can be categorised in several areas;
Disk forensics involves extracting and analysing archived, stored and deleted data from hard disk image files.
Network forensics involves analysing network traffic and network devices for evidence.
Wireless forensics involves analysing wireless networks to determine if they have been infiltrated by intruders or if they were used to commit an adversary. It also helps to document evidence as information regarding connected devices helps during the investigation process.
Database forensics analysing database for stored information. Databases also reveals deleted data.
Malware analysis involves analysing malware to determine hidden processes, malwares and Dlls used by attackers to execute malware. Volatility framework is one of most powerful tools used by digital forensic experts for malware analysis.
Memory forensics involves computer memory dump extraction using tools such as Bulk Extractor and then analysing the memory dump for evidence. Popular tools for memory forensics include Autopsy.
Mobile phone forensics include analysing mobile phones for evidence. This has become a popular field in digital forensics due to the continued use for fraud. Android forensics is very popular due to the high number of Android phone users. However, conducting Apple forensics is at times difficult due to the high level of security and encryption applied on Apple products.
As a digital forensics student, there tools that you should learn and practice how to use. Despite the difficulty in learning these tools, it is always essential to gain experience in using since they will be applied in your career. Our Digital forensics experts are skilled in using the following tools
