Digital forensics Management Introduction Digital forensics is the collection, preservation, analysis and presentation of digital evidence. This essay outlines the vital part digital forensics plays when it comes to certain court cases and the retrieval of the digital evidence and the impact that digital evidence has on the ruling of the cases. Case No. 11-CR-00471-DLJ (PSG).This is a court case in which the United States of America opened a file against 14 defendants who tried to violate a protected computer. “The 14 defendants in this case were indicted on July 13, 2011 on 15 counts of conspiracy to cause damage to a protected computer and aiding and abetting causing intentional damage to a protected computer, …show more content…
In this Case No. 11-2121. Parents of a child reported an incident in which they stated that their child had sexual intercourse with an adult male. This is a case between United States of America, Appellee, v. Darrin Roy ANDERSON, Appellant, in which they hold Anderson accountable of traveling with the intent to engage in illicit sexual conduct, in violation of 18 U.S.C. § 2423(b), to which Anderson pleaded guilty. The evidence retrieved in case 2 was the text, the photos and further investigations indicated that Anderson withdrew $200 on August 11, 2009, from a cash machine in Walhalla, North Dakota, where he worked. He withdrew another $200 from a cash machine in East Grand Forks, Minnesota, on August 12, 2009. Funds from the same account were used to pay for a room at the East Grand Inn on August 12, 2009. Facebook was used as a method to trick the defendant in thinking that the person he is communicating with is one of the adolescents he had sexual intercourse with. The two parties communicated back and forth and Anderson agreed on meeting up with M. R’s mother. The outcome was that Anderson actually had more than 800 private chats with more than 800 adolescent girls, this was after a search was launched by Detective Hajicek. Anderson was then found guilty and prisoned for 114 months. The result of this case is quite fair as there was sufficient evidence to prove that Anderson was internet …show more content…
: CC 02/2012. Case 3 is a murder case. In which “the accused Paulus Thomas was charged with the offence of murder, read with the provisions of the combating of Domestic Violence Act in that he on the 29th of November at Uuthilindi village, in the district of Oshakati, allegedly killed one of Johanna Lazarus (deaceased)”. Not much of digital evidence was used in this case, but the witness Lahya Naivela a cousin to the accused in case two testified that “on the night of 29 November 2010 she was called twice on her cellphone by the accused, but from a different number than his registered on her phone”. This information she provided was retrieved from a MTC call list printout which shows the time frame the calls were made which is on the 29th November 2014 22h45 and 23h41. The witness stated that it was Thomas who spoke with her on both occasions stating that he killed his girlfriend. The evidence provided by the Risk Administrator at MTC, Windhoek, Hilia Eliakim was data records from their system reflecting the information about phone calls and text messages made from a certain number, the duration of the call, time and date, the serial number of the phone and the receiving tower that registered the call. Them,
In this position paper I have chosen Bloodsworth v. State ~ 76 Md.App. 23, 543 A.2d 382 case to discuss on whether or not the forensic evidence that was submitted for this case should have been admissible or not. To understand whether or not the evidence should be admissible or not we first have to know what the case is about.
The last case we will look at involved a man named Gary Dellapenta. Back in 1999 he was charged with using the internet to solicit the rape of a woman who rejected him. Dellapenta posted internet ads on the computer giving out her address, ways to circumvent her alarm and that she had fantasies of being raped. Her father posed as a responder and was able to back trace the IP address to Dellapenta. Dellapenta plead guilty and received three counts of solicitation of sexual assault and was given six years in prison. (Man Charged, 1999)
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.
Evidence essentially comes in two forms: verbal or physical. For instance, verbal evidence could be spoken evidence acquired from a wiretap. Physical evidence could include DNA, blood, or bodily samples. Another reliable origin evidence is digital documentation. “As technology has become more portable and powerful, greater amounts of information are created, stored, and accessed” (GEDJ). Over the past few decades, technology has advanced to extreme levels! The most common technology used to find digital evidence are cell phones, computers, tablets, external storage devices, GPS locators, and various other devices (GEDJ). Text messages, social media posts, pictures, etc. are becoming more common data in investigations of the modern era. “Digital evidence can come from both suspects and victims, as all involved parties may have their own personal devices that are relevant to the investigation” (GEDJ). If they are available, computers, phones, social media and much more are very useful sources of gathering data for a criminal case. For instance, both the suspect and the victim may have text messages on their cell phones that could add to the search. “In some criminal cases, digital evidence can be useful if the suspect had associated with it. In some cases it can lead in the wrong direction or to the wrong people. Or it could simply be useless if the suspect didn 't use anything digital”
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.
This is a process model in electronic crime scene investigation guide, published by U.S. Department of justice, where the first responder has to carry these steps to conduct examination processes and report in the later part. Brian Carrier & Eugene H. Spafford (2003). Even though there are processes listed clearly to protect the available evidence, there still will be challenges when handling different electronic gadgets. Smart phone for example, it gives several challenges to investigators and cyber forensic s...
Evidence collection is a crucial part of forensics. Its reliability can be compromised by input bias from law
We are being hired as a consultant to help respond to a small medical office in which they learned that 10 of their employees have been victims of identity theft. The office has 55 total employees amongst two office locations. They have one workstation per employee and different kinds of computer operating systems in use. There is a mixture of Windows 7, Vista, and XP operating systems. The servers being used are Windows 2003 and 2008 versions. This is used for the billing system which hasn’t been updated to cloud services. As a consultant, I will try to help the business by looking at how their information was being received by the attacker, to prevent further attacks, and to check
The collection, custody and preservation of forensic evidence is a vital aspect of evidence integrity, without proper adherence to these procedures, crucial evidence that could potentially have great impact on a court case could be rendered useless. In the case of criminal proceedings, a skilled defence lawyer will look to scrutinise every step taken by forensic practitioners’ involved within the case in regards to the continuity of the evidence, in doing this they attempt to undermine the practitioner’s ability to properly carry out strict evidence collection, protection and preservation procedures and also look to find fault in the techniques they used to carry out these procedures.
In conclusion, I understand in digital forensics when copying a bit by bit of a hard drive the examiner must use a write blocker, either software or hardware to avoid possibility of accidentally damaging the evidence contents. After imaging is completed the forensic examiner will have a generated hash value of the bit by bit copy of the evidence hard drive. This hash value (dіgitаl fіngerprіnt) is important to digital forensic because it shows the integrity of all evidence is maintained and to avoid tampering or spoliation. So my question is this, how can we say the integrity of the client's forensic image evidence is not tainted when we know for a fact that the client's computer was filled with malware infections (Trojan)? In my opinion by the time the examiner started investigating the client's hard drive all the
Digital Forensic is described as “ a forensic science encompassing the recovery and investigation of materials found in digital devices “ (“Introduction to Digital Forensics,” 2011). The objective of digital forensics is to implement a well-structured investigation while preserving a documented chain of custody and evidence custody form to know what really occurred on digital devices and who was accountable for it.
Technology has opened new encounters and opportunities for the criminal justice system. There are so many new practices of criminal activity, such as computer crimes. There are different types of computer crimes that many people become victims of every day. Computer crime is any crime that involves a computer and a network. The computer may have been used in the commission of a crime, or it may be the target ("Computer Crime: Chapter 2: What Are the Crimes?", n.d.). Crimes such as data diddling, pump and dump, social engineering and spoofing are computer crimes. Even though these crimes are difficult by privacy issues, the new technology has made investigations and prosecutions well organized and effective. Though views are different on the pros and cons of specific technological changes in the criminal justice system, there is an agreement the system has changed affectedly ("Effects of Technology in Criminal Justice | eHow", n.d.).
Digital Evidence is electronic data, materials, objects, property, documents, or records that are presented in court to prove or disprove allegations made against an arrestee. It takes the form of electronic data or information stored in bits and bytes on magnetic media. The examples of devices that can contain digital evidence include; cellular phones or similar all in one devices, pagers, digital voice recorders.
A forensic interview is a structured conversation with a child or minor with the intention of eliciting detailed information about a possible event (s) that the child many have experienced or witnessed. Concurrently, for Van Heerden (1977: 8) forensics refer to the computerized activities or scientific knowledge employed by law enforcement agents to serve justice. In the study, forensic investigation is used to refer to any computer-related activities or methods used by police, investigators, prosecutors and all other law enforcement agents to gather facts, track down criminals, arrest or detain them, gather information, preserve information and finally present it in the court of law.
No matter what kind of digital evidence is involved, once must always take the proper steps to preserve the evidence. The slightest mistake during the seizure, storage or investigation can cost the investigators precious evidence, or even the case. Though every case must be handled differently, these steps are a beginning on how to handle digital evidence. As technology and the crimes committed with it evolve so must the techniques in acquiring and preserving the information.
