Now-a-days the technology advancements is are now mainly used for crimes. To investigate this occurring crimes digital forensic investigator is required. Acquisition Methods: There are two types of acquisition, they are: Live and Static. The live acquisition is done when password is involved, where the static acquisition is involved when the evidence is seized. Acquisition methods are of four types: they are bit stream disk-image, bit stream disk-disk, logical disk -disk method. Disadvantages: 1. It is time consuming, when the larger image file arise. 2. The difference between the original and duplicate image finding is very tough. 3. Modification of evidence has a chance Investigation with Network Administrator: Diplomatic approach is obliged while conversing with network administrator. They knews the most about the system and computer and I can get the critical data about confirmation and suspect from him. Certain inquiries which I can ask are; investigation has happened some time recently, did he think anybody that any extra representative as of late, the amount of access is given to workers of investigation office and any progressions made in client comes and drive after the occurrence. These inquiries can help in discovering the
suspect. It is very important to maintain the data integrity in digital evidence as they can be altered. For the validation of data, it will use tools like X-Ways Forensic, IDM computing solution Ultra compare.

Forensics investigations that require the analyzation and processing of digital evidence can be influenced both positively and negatively by a number of outside sources. In this paper, we will explore how physical security plays a role in forensics investigations activities. We will start by examining how physical and environmental security might impact the forensics investigation process. Next, we will discuss the role that physical and logical security zones play in supporting effective forensics activities. We will illustrate how centralized and decentralized physical and environmental security affects the forensics professional’s approach toward the investigation. Lastly, we will evaluate some potential areas of risk related to the physical security of our case study organization, Widget Factory, identified in Attachment 1.
Forensic science has paved the way to a new world of technological advancements in solving crime, through DNA analysis, new technology such as M-Vac, improving systems such as CODIS and other investigative methods. As forensic science technology advances, the chance of an individual being able to commit a crime and walk away free without leaving any trace of evidence will lessen. While forensic science has its limitations, it can be the only way to provide an accurate account of what actually occurred at some crime scenes.
A structured standardized approach to any evidence collection is going to be the best course of action. Any well-training computer forensic technicians should not jump into a search without some kind approved policy procedure which will include a checklist or standard operating procedure that will methodically guide them throughout the examination procedure. The cyber forensics should not be taken lightly and it starts with its collection methods.
Technology is used by every single criminal justice practitioner in some way, shape or form each and every day. When it comes to crime analysis technology is there to help with accurate analysis of the crime scene or evidence obtained. Some examples of the technology used in crime analysis include radios, telecommunications, computer, data storage and collection. Each technology has its own unique role during crime analysis, all are equally important. Computers, data storage and collection would be the main technology that is used to assist during crime analysis. Computers are necessary for accurate crime analysis because they cut the chances of mistakes being made. Further all the information needed is stored within the computer for access later by any law enforcement official in any state. Basically that means that any and all data that is collected, stored and processed will be the same as it was when it was entered into the system and will remain accurate when it is needed by law enforcement agents or when it is needed for crime analysis.
Despite these advantages, Grispos, Glisson and Storer (2012) highlighted several challenges that the cloud environment may pose for digital forensic investigators during the collection and analysis phrases of the investigation process. Artifacts, data used that can be used as evidence, are often hard to extract because resources can be redirected and/or disappear destroying the trial of evidence in the process. During the preparation stage of the investigation, an investigator trained in the conventional methods of digital forensics will usually obtain a comprehensive history and overview of the crime scene, and have a idea of what will be required from the organization in order to proceed with the investigation. However, in the case of network forensic investigations, there is a no comprehensive history and overview of the suspected crime scene, and there is a lack of structured environment in which data transmissions between various network points and platforms can be collected as evidence. There may also be a lack of structure in the target environment and methods of monitoring and reporting transmission information may not exist. The segregation of duties and differences in the service models that exists between cloud service providers and cus...
Judit Jimenez Computer Concepts Tara Bosma May 10, 2018 Digital Forensics Analyst According to Study.com, a digital forensic analysts is someone who collects information from digital devices as part of legal investigation. Computer forensics analysts combine their computer science background with their forensic skills to recover information from storages devices and computers. The analysts are responsible to assisting the law enforcement officers with cyber crimes and they also retrieve evidence that way. Computer forensic analysts usually hold a bachelors in computer science with a background in criminal justice.
First is to examine each of those projects to the corporate objectives, compare and contrasting project selection criteria and justify why a project meets the selection criteria.
The transitional growth in the forensic science sector has not been without challenges. Though the world has experienced increased capabilities and scientific knowledge, which has led to faster investigations and results, many forensic experts have argued that forensic laboratory testing, in the light of 21st century technological advancements, is yet to meet the expected rate in quick available testing and analysis (Mennell & Shaw, 2006). This is with respect to the growing rate of crime and the high demand of quick crime scene testing and analysis. In the science of crime scene, analysis and interpretation of evidence is majorly dependent on forensic science, highlighting the change in the role of forensic sciences (Tjin-A-Tsoi, 2013). In the business of forensic science, time is beginning to play important role in the evidence testing and analysis which is becoming crucial in reducing ...
Illegal access and modification of data will be discussed in this research paper. David Noel Cecil gained illegal access into Platform Networks, an internet service provider and stole the username and password of Platform Networks managing director. In a period of ten days, David Noel Cecil got into the company’s system multiple occasions which summed up to forty-eight times (CDPP, 2011). David Noel Cecil, modified the file structure of the computer system in one of the forty-eight occasions, which resulted in the Platform Networks internal system going off line for some time. David Noel Cecil, also run several commands on the companies system which lead to a compromise on the companies system (CDPP, 2011).
Forensic science has now been recognized as an important part of the law enforcement team to help solve crimes and cold cases. The advances in technology are being used each day and we must continue to strive to develop better advances in this field. The recent discovery of using DNA in criminal cases has helped not only positively identify the suspect, but it has helped exonerate hundreds of innocent individuals. “With new advances in police technology and computer science, crime scene investigation and forensic science will only become more precise as we head into the future.” (Roufa, 2017) Forensic science and evidence helps law enforcement officials solve crimes through the collection, preservation and analysis of evidence. By having a mobile crime laboratory, the scene gets processed quicker and more efficiently. Forensic science will only grow in the future to be a benefit for the criminal justice
In conclusion, computer crimes have increased in the recent past because of the proliferation of these devices due to technological advancements. This has in turn contributed to the emergence of computer forensics, which involves the use of various processes and tools to gather evidence that is admissible in a court. There are various types of computer forensic tools or programs with different features, costs, and areas of effectiveness. Similarly, there are various computer experts for various computer crime scenarios. Since these experts are only suitable for varying computer crime scenarios, the hourly costs of hiring them differ based on the specific details of the case.
Static Acquisitions: if you have preserved the original media, making a second static acquisition should produce the same results. The data on the original disk is not altered, no matter how many times an acquisition is done. Your goal when acquiring data for a static acquisition is to preserve the digital evidence. Many times, you have only one chance to create a reliable copy of disk evidence with a data acquisition tool.
the Abstraction layers that translate Raw Data into a form so that the investigator can find the errors. The Potential for error in data representation is unique to digital crime scene and requires extra precaution by the investigators such as compairing the results of multiple tools and inspecting the data at lower levels to double check the veracity of information that has been displayed through the forensic tools . digital investigator while searching a digital crime scene may encounter information which may have personal data and even evidences relating to other crimes he
What did they do ? Before we talk about it any further, we have to know some definitions that we use in digital forensics and digital evidence, not only two of them but the others too. This chapter will explain about it . Before we talk about it any further, we have to know the definition of what we are talking about. In the introduction we already know what digital forensic and digital evidence shortly are. In this chapter, we will more explore what they are, and some state that we found when we search about digital forensic and digital evidence. Computer forensics is a broad field and applied to the handling of crimes related to information technology. The goal of computer forensic is to securing and analyzing digital
Since the old times primary investigations do not typically yield enough information to prosecute a criminal case. The information yielded in criminal investigations may be used to prosecute a criminal case or can even assist in a federal case. Even though primary investigations can identify a lot of evidence and information, a secondary investigation will usually identify further details and allows for a second look at everything pertaining to the investigation. This paper is to explain criminal investigations and the necessary tools and skills needed to conduct and thorough investigation.
