2.4 Challenges of Digital Forensics
Digital technology evidence gathering and presentation presents challenges that are inherently different from other kinds of forensic investigations in other fields. Digital evidence is different from evidence that has been created, stored, transferred and reproduced from non-digital formats (Chaikin, 2004). In his study, he showed that the main difference between digital technology evidence and other forms of forensic science practice is the fact that digital evidence can be maliciously or accidentally manipulated by the actors involved thereby nullifying the validity of such evidence in proving the occurrence or existence of crime.
The differences in the nature of digital evidence …show more content…

As technological advancement continues to outpace the skill acquisition rate of practitioners in the field, the challenge of adequate resource continues to pose as challenge to digital forensics.
Researchers have identified three factors as contributing to the increasing data volume which has become an issue for digital forensic practitioners. These factors are the increasing number of electronic devices available to users, the increase in device memory sizes now available at cheaper costs, and the number of investigations that involve application of digital forensic techniques. Examiners spend larger time closing out investigative cases with huge burdens placed on forensic laboratories.
However, as a way to overcome or limit the impact of this challenge, Rueben et al (2005) offered suggestions that can be adopted. This include; investigators only focusing on acquiring, examining and reporting on the data that is relevant to the case at hand. To determine relevant data, focus on the peculiar nature of the case and knowledge of the investigator can be criteria for making this judgment. As forensics involves working with data to generate relevant evidence, the possibility of applying the appropriate technology is key to ensuring …show more content…

This layer describes the storage area on the device where the application is stored.
In general, there are three storage locations where social networking applications are stored. The first location is known as the Application Sandbox. The application sandbox is the standard location for most social networking applications; especially applications that run on the android and the IOS operating systems. Data stored on the application sandbox is not accessible to other applications that may be installed on the device; meaning this data is available only to the social network application itself. Represented below are the application sandbox storage locations of Skype on three different device types: o Android Device: /data/data/com.skype.radar o IOS Device: /private/var/mobile/Applications/789888-BCD6-7E5F-1425FDFFDE o Personal Computer:

This ultimately results is a subsequent communication which requires the holder to disclose those passwords or taking on an additional task of tracking the passwords. In both the cases, the level of work is expanded and the police investigator has to take on additional tasks then he was initially required to. This while increasing the cost of investigation also increases the time taken in investigation. Therefore while identifying the property, or the hardware of the computer, an inclusion needs to be made in relation to the passwords that may be protecting that hardware. Similarly for the data demanded in the digital format the investigator, would have to highlight that mere data in digital format is not required, but also the passwords or the code's which restrict access to that data are also required.

i. Manage The term manage is used to mean acquiring the necessary contractual vehicle and resources that include financial resources that are used in running forensic labs and programs. It can also be used to mean to coordinate and build internal and external consensus that can be used to develop and manage an organizational digital forensic program. Management also is to establish a digital forensic team, usually, the one that is composed of investigators, IT professionals and incidents handlers to perform digital and network forensics. Management provides adequate workspaces that at minimum take in to account

Comparing simple techniques simply to retrieve a piece of evidence is completely different as we learn more about the science and learn from the mistakes made in the past. Looking back at the 1800’s and comparing the technology of the 21st century, the difference is certainly huge. The increase in technology makes information more vast and more ideas can be shared easily. Many sciences are based off many “what ifs” while forensic science is more factual and attempt to solve puzzling occurrences and events and get down to what truly

4.7.5 Data Preservation and Isolation from the Network. The main purpose of a digital forensic report is to keep the data integrity, avoiding any type of data alteration, in order to present valid evidences, for instance in a court. The use of not valid software to check the stored information in a mobile phone can alter these information. The action of receive new data can alter the information stored, for instance an automatic firmware update, or remote device control with the risks involved. Therefore, it is extremelly important have the device completely isolated from the network.

dishonourable false testimonies in 1987, at the trial for a case of double rape that put Dale Woodall, a 29-year-old from Charleston, West Virginia, in prison for life. A brief background of the case entails a man wearing a brown and yellow ski mask had taken hold of two women outside a Huntington, West Virginia, shopping mall and raped them in the car of one of the victims. The women, not able to offer thorough account of the rapist, were ‘forensically hypnotized’ to improve their memories. Dale Woodall was put on trial, and Fred Zain distinguished one of his pubic hairs as being in the victim’s car and a semen stain as matching his blood type. ‘He testified that 1 in 10,000 people had Wooddall 's grouped and subgrouped blood type, a statistic

When it comes to lawmaking in the present-day United States, many things influence proposed bills and passed laws, like current or possible issues the country could face noticed by the legislative branch.

As far back as 2001 when the first “Digital Forensics Workshop” was held and a case for standards was made, considerable progress has been made in ensuring the growth and expansion of the practice of computer forensics. Mason (2003) suggested the need for standards by which digital forensic practitioners ensure that evidences for prosecuting cases in the law courts are valid as more judgments from a growing number of cases were reliant on the use of electronic and digital evidences in proving the cases. XXXX (2005 & 2007) emphasized the dynamic nature of technology and its impact on the digital forensics field. Hence, the need for having early standards in regulating the
