Computer forensics are used in many fields, from legalities involving trade secrets to prevention of computer-related fraud; however, more and more computer forensics are being used to help solve crimes of all kinds. Computer forensics have both obvious and less obvious implications in a criminal court and are a helpful new tool for prosecutors and police alike.
The area of computer data was something that was ignored or under used in court cases for far too long. This was even worse because most criminals are very, very sloppy about their data encryption - they make the game easier for the forensic guys.
This type of forensics use scientific methodology to protect, assess, and analyze computer data. Deleted data may be retrieved or recovered,

Theft, embezzlement, and fraud may all have computer records and evidence that is assessed and analyzed by a forensics specialist - there's very little done in business today that doesn't involve computers at some level.
Even the use of cell phones isn't safe from the forensic guys. Every text message you ever sent, every phone number you ever stored or even any images you ever kept on your cell phone are all items that these guys can undelete and use against you in a court of law. There have been several high profile murder cases examined in the last few years were cell phone forensic evidence played a key role in the prosecution of the criminals. That's right - they were stupid enough to send each other text messages organizing the murder of another human being.
Specifically, computer-related crimes, such as hacking, child pornography, and intellectual property theft are also prosecuted with the aid of computer forensics. Furthermore, these forensic teams aid in the search and prosecution of terrorists who may use computer technology for planning, scheduling, and locating acts of terrorism. This has become especially important after
In today’s world we have progressed far past Benjamin Franklin’s discovery of electricity. We have shaped and molded technology to provide us with less hassle, less work and a more convenient way to communicate. In the world of crime, technological advances have taken us above and beyond as we master to seek the truth through polygraph tests, or the way we link a suspect through DNA samples from a crime scene ; Even the way we have administered technology with the death penalty has advanced far beyond we ever imagined. Technology has been useful to solving many crimes and will continue to advance
It allows in a case For investigators to and hidden or deleted storage/information and help prevent or catch criminal acts.
Electronic evidence is very fragile because it can be destroyed or altered very easily, therefore it is imperative that investigators follow very careful all the procedural steps when collecting electronic evidence (Diversified Forensics). Before any electronic evidence is gathered investigators should determine whether there is probable cause that a crime has been committed, or if the crime was committed somewhere else the investigator should determine whether the electronic evidence will aid the investigation process to prove or disapprove the crime, if a warrant is needed it must be obtained prior to collecting the evidence (Diversified Forensics). Hard drives, computers, and other electronic devices must be turned off, unplug all cables,
For this reason, it is imperative that the information gathered is reliable and accurate to ensure the evidence collected can be utilized by the digital forensic investigator for the current case (Ingalls & Rodriguez, 2011). Additionally, cyber incidents require digital forensic investigators to interview various individuals regarding the information needed for the case. According to the National Institute of Justice (2004), interviewing the system administrator, users, and employees of an organization regarding a cyber incident would provide investigators with valuable information; for example, user accounts, email accounts, network configuration, logs, and passwords. Furthermore, for digital forensic investigators to conduct an effective interview, they must have the proper tools and training to employ the interview process. For instance, formal procedures or instructions should be developed and implemented to ensure that the investigator follows a standard during all investigations. Additionally, training should be provided to ensure that digital forensic investigators comprehend by what means to prepare, conduct, and evaluate an interview. Furthermore, resources should be made available for digital forensic investigators to accomplish their tasks; for example, recording devices and references. Also, definitions should be provided to the digital forensic investigators for
A computer forensic investigation typically includes the collection, examination, analysis, and reporting of data. These steps could have been used to extract and preserve the data in the U.S. versus AOL case. Collection involves seizing digital evidence. Examination is where techniques are applied in order to identify and extract data. Analysis is using the data and resources to prove a case (Brecht, 2015). Reporting involves presenting the documentation gathered during the investigation. Investigators use these steps to examine evidence that could be needed in a trial. Following these steps is one way to ensure that the findings are sound and admissible in court. “The purpose of a computer forensic examination is to recover data from computers seized as evidence in criminal investigations (Brecht, 2015)”. Forensic tools are used by investigators to provide their collection, indexing and detailed analysis
When was the last time she accessed her computer? What is her background in computers, what is her skill level? I need some background on the former employee, her computer habits and activities prior to the files being found on her computer. I must collect digital evidence while keeping the data unaltered, first thing. This data will be used later in the prosecution of the case. This can be done through calculating and recording an evidence file. Next is imaging of the computer media with a write-blocking tool. I must keep the chain of custody. The computer's RAM is examined for evidence. During the examination step, verify and catalog the presence and integrity of the original evidence and any copies. An analysis is made with specialized equipment to find out exactly what's stored on the digital media. This includes a manual review of all materials found on the media, a review of the Windows registry, techniques to crack passwords and retrieve protected data, keyword searches and extraction of email and pictures for further review.
Digital crime has been on the increase due to the increasing use of computer and internet. This has led the investigators with another method of fighting this crime. This is Computer Forensics, a process of going into computer hard drive and capturing basic information the user believed it has been erased.
This means that digital evidence is hard to destroy and that in order to completely remove the evidence from the internet, one must possess a high level of knowledge in the area (Casey, 2011, p.26). This means that criminals who conduct online crimes will always leave online trails and it is up to the digital forensic scientists to retrieve the evidence (Casey, 2011, p.26). This is a strength and it also shows us why digital forensic scientists can play a crucial role as they are the few people that are trained in locating the trail of evidence left behind by the
Computer forensics is a new area of crime investigation. However, it is an area of knowledge that is growing at a faster rate. Computer and network forensics investigators are professionals who are mainly trained on various investigation activities related to computer crime. They are trained on how to investigate computer crimes
Computers are common tools used by the culprits behind white-collar crimes. In order to find “culprits,” the forensic accountant will need to be able to dig deep into the company’s computer system. However, without the proper equipment, that process can prove to be very difficult. To facilitate the preservation, collection, analysis, and documentation of evidence, forensic accountants can use specialized software and computer hardware.
The OS provides digital forensic investigators with the primary application where the files, folders, and logs of every event that has occurred involving the suspect’s information system can be located. Furthermore, this information can be utilized by the investigator’s to understand how incidents like network intrusion, malware installation, and insider file deletions have occurred. As a result, OS’s is the location where relevant information on incidents or unlawful activities can be discovered with the proper collection and examination
This manual is to assist forensic technicians who may be responsible for preserving electronic crime scene and recognizing, collecting, preserving, and storing digital evidence. When dealing with digital evidence, these principles apply: The process of collecting, securing, and transporting digital evidence should not change the evidence in anyway. Only trained forensic technicians specifically for digital evidence should conduct the analysis. Everything done during the search, seizure, transportation and the storage of the digital evidence should be documented, preserved and ready for review.
Technology is used in this world by many people. They use it to perform research, communicate, teach, perform medical procedures, commit a crime, and so forth. Since it can be used for various reasons, it can be also be used against a person in a court of law as evidence in a case. As technology advances and more people use technology for their own purposes, cybercrime also increases in society.
In a world where technology is increasingly becoming the way of life, it was only a matter of time before crime was no longer just in the streets but happening online as well. Criminals now get a new approach to carry out their crimes with the use of computers. Since technology is more like a murder mystery than catching the bad guy in the act, a new discipline of forensics needed to be put into place. This is known as computer forensics. Forensic science is any science used for the purpose of law. In the case of computer forensics it is “the discipline that combines elements of law and computer science to collect and analyze data from computer systems, networks, wireless communications, and storage devices in a way that is admissible as evidence in a court of law” (U.S. Cert, 2008). Meaning if you do something illegal on the Internet it can be found.
In simple terms, computer or digital forensic evidence analysis is the scientific collection of data that is either retrieved or held by a computer storage device that can be used against a criminal in a court of law. For the information to be used in court it should be collected before it is presentation; therefore, there are a number of recommendations proposed to make sure that information collected meets the intended integrity.
