Computer forensic is explained as an application used for investigating and analysis methods used for gathering and also the preservation of evidence from computer evidence that will be presented in the law courts (Blokdyk, 2019). The main objective of computer forensic involves identification, gathering, preservation as well as analyzing data in such a manner that the integrity of the collected evidence is not compromised. The data is then used for legal purposes.
Soundly conducting computer forensic will increase the integrity as well as the surviving ability of the network infrastructure. A deep understanding of the technical and legal aspects of computer forensic will help an organization in gathering essential information in the case of a compromise as well as take legal actions.
Computer forensic help in eliminating the sampling risks, making a comparison of data from various systems, as well as enhance a steady identification and the extraction of the data population for analysis (Sako, Schneider, & Ryan, 2019). Computer forensic also helps in identifying the different trends which may not be known by the consultants, the investigators, or even the personnel’s in the company.
Digital devices like cellphones, computers, and also GPS have been used globally, making it essential to analyses digital evidence to be used in the prosecution of different types of crimes. Computer forensic enables the collection and revealing of the information regarding the movement of criminals, a crime that has been committed, and also in identifying all the associates of the criminals (Blokdyk, 2019). The incriminating documents that are used in criminal prosecutions such as those of drugs, homicide, embezzlement records, and financial fraud can be traced through computer forensic. The investigators may take photographs, measure the scene, and also ensure that the collected evidence is in the proper custody. The investigators also collect evidence such as footprints, blood, body fluids, fingerprints, fire debris, among others at the scene of the crime
There are various tools used in computer forensic to gather and store evidence. A disc imaging software is used for recording the content as well as the structure of the hard drive. The software gives room for copying and preserving information according to the relationship of the files. The hardware and software write tools are also used for reconstructing and copying the hard drive in small portions (Blokdyk, 2019). Write tools for hardware and software. Prevent the collected information from being changed. At some point, the investigators are required to pluck off the hand drives from the computer of the suspect before they can make a copy.
Hashing tools are used to make a comparison between copies and the information in the hard disks. The devices are used to analyses data and also assign unique numbers on the data. When the print harsh numbers match with the hash of the original text, it is an indication of a perfect replica. Additionally, the investigators use programs for file recovery to gather and also restore the deleted data. The programs locate all the data that is awaiting deletion.
During litigation, computer forensic is of great importance. Every organization or even individuals are making use of computers in their daily lives (Nelson, Phillips, & Steuart, 2018). Criminals, too, are using the computers to hack the networks and other systems. Computers have become a dominant type of technology globally. The use of computers for different purposes has enhanced the need for electronic and digital evidence.
Computer forensic gives the investigators a lot of benefits, with the main one being the ability to analyses and search a large amount of data efficiently and also within a short period. The availability of search keys in the hard drive, which is indifferent languages, gives the investigators a lot of benefits.
Computer forensic facilitates the retrieval of valuable data that had previously been lost or deleted by criminals. The retrieved data provides the court with substantial evidence. Additionally, computer forensic has made it possible for legal professionals to service the courts with data that was previously impossible.
The process of computer forensic therefor involves identification, preservation, extraction, and also the documentation of computer evidence to be used in the courts of law. Computer forensic comes in different forms, such as wireless forensic, database forensic, malware forensic, email forensic, disc forensic, and also memory forensic (Le-Khac, 2019). Some of the cases where computer forensic is applied include industrial espionage, theft of intellectual property, fraud investigations, and also employment disputes. Computer judicial employees various techniques such as the live analysis, the cross drive analysis, and even the deleted files analysis.
Despite the many benefits and disadvantages that are attached to computer forensic, the practice has its share of challenges (Rahman, 2019). The significant difficulties include training, education, funding, and the volume of data as well as understanding the technology in use. Technical challenges involve wiping of the residual data, investigators being attacked, attack of the investigator’s tools, wiping of remaining data, as well as the encryptions.
The knowledge of computer forensic is thus important, more importantly, in the courts of law. The practice can be used by investigators, law enforcers, insurance companies, corporations, and individuals, among many. Computer forensic enhances the work of the forensic team as they inspect, analyze, identify, and also preserve all the digital evidence from different electronic devices.
