The Digital Of Digital Forensics

When faced with problems as a computer forensics investigator you must be very flexible. There are many different types of computer related crimes in today’s society. They may range from child pornography to identity theft to even insider trading on Wall Street. The possibilities for the criminals in our world to use computers and the Internet against us are endless. The computer forensics or cyber forensics fields are growing but are still learning every day because it is such a young field of study. New things emerge every day that computer forensic investigators must adapt to and begin to learn to help combat these criminals. Investigators will use many tools to help them find incriminating evidence. These investigators must learn these tools inside and out to make sure every test they run can be valid. The computer forensics field is growing rapidly and there are a lot of real world threats that we need these investigators to help us solve.

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

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.

Data is crucial to the success of any company and they are now increasing their efforts in soliciting and retrieving customer data to learn more about their client's preferences, likes, and dislikes. This, among other factors has attributed to a growing field of data science where data scientists learn to collect crucial data. While there are many types of data, this paper will primarily focus on digital data and how digital scientists can retrieve these data to support provide information for the crown or for the defense. This area has received more attention because criminals such as terrorists have realized the effectiveness of using digital devices to aid in their criminal endeavors (Reith, Carr & Gunsch, 2002, p.2). To combat this, law enforcement agencies are now relying on digital scientists to preserve, collect, analysis and interpret "digital evidence derived from digital sources" (Vincze, 2016, p.184) to help prevent cybercrime and prosecute (or exonerate) suspects. The purpose of this paper is then to illustrate why digital forensic is crucial to addressing the new dangers presented in our society by analyzing the strengths and demonstrating why the weaknesses of the field

Digital evidence is defined as being evidence that takes form as electronic data, or information stored in bits and bytes on magnetic media. Digital evidence cane range from photos, videos, text documents, internet activity logs, phone numbers, or any other data that is stored electronically that has involvement with a criminal case. Devices that can hold digital evidence are personal computers, computer media, disks, CDs, DVDs, etc. and cellular phones or similar all into one devices and many other types of devices as well. When preserving digital evidence extreme care must be taken. Investigators are sworn in to never change or altar evidence digital or not. Digital data however is very fragile and extra care is imperative. So the first and foremost concern when dealing with digital data is to preserve all data on the hard disk drive or other computer media in a pristine, unaltered, unharmed and unchanged manner.

Although computer forensics is a relatively young field of crime investigation, it has become a useful area of knowledge. Organizations and companies are finding it necessary to recruit computer and network forensics investigators. These experts can detect and report various computer crimes. The reports of their findings can be used to provide useful evidence in court. This paper discusses various aspects of computer forensics. It is based on a scenario involving a computer, which is suspected to contain evidence on child pornography.

Supportive investigation procedures and protocols should be in place in order to show that the incriminating evidence was on the electronic media. Crime has changed since the dawning of the computer age and the need for digital forensics is growing rapidly. Digital forensics has various areas based on different standards and media types, each with experts. There have been major breakthroughs in digital forensics

Digital forensics has been responsible for putting away thousands and thousands of criminals. Ranging from simple crime computer crimes to child pornography. To get quality evidence that can be admissible in court there are steps that are needed in preparing a computer investigation. There are also requirements for data recovery, as well as procedures for corporate investigations. “Digital forensics has become prevalent because law enforcement recognizes that modern day life includes a variety of digital devices that can be exploited for criminal activity, not just computer systems. While computer forensics tends to focus on specific methods for extracting evidence from a particular platform, digital forensics must be modeled such that it can encompass all types of digital devices, including future digital technologies” (Reith, Carr, and Gunsch, 2002).

Having digital forensic capabilities is very important in this era we are in. At our company, we have an in house forensics team that consists of a senior forensic investigator, project manager, computer forensic examiner, legal counsel, IT specialist, and three lab assistants.

Over the last few years law enforcement has shown some major development and growth when it comes to forensic technology. The use of things such as cell phones, computers, gps devices has drastically increased. As a result, these devices regularly contain vital evidence, including user data, call logs, position, text messages, email, imageries and audio and video recordings. When it comes to cyber forensics, law enforcement has a substantial challenge in keeping current with technology changes. New technology is released onto the marked very quickly, both hardware and software. It is imperative that these agents know when these things will hit the market and how to use them. The enormous capacity of information contained on digital devices

The appropriate use of evidence plays a vital role in case’s hearings. Digital Forensic analyst accumulates all the evidences from the crime scene and then evaluates the evidences and analyze the result before presenting it in the case hearing. Digital Evidence Analysis can be done with the use of data that is extracted from any type of digital electronic device. In any of the cases, where a guilty person is involved in illegal activity, such evidences and devices are used can be used to find the actual guilty person.

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.

Digital forensic has been growing from year to years. There has many challenges for digital forensic. Nowadays, no one not use a digital device and many people doing wrong thing with a digital device. That why, digital forensic have aim 5W’s which is Who, What, Why, When, Where to track all crime and solve them. This paper explores the current challenges of digital forensic and its future directions of digital forensic.

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.
