For financial fraud investigations large amounts of data and information needed to be collected. It involves the data gathering through database, interviewing, searches and collecting the documentary evidence. The evidence can be collected through email, faxes, chats and financial records. Through the advancement of technology there are vast means through which the evidence can be collected.
“The special properties and technical complexity of digital evidence often makes it even more challenging, as courts find it difficult to understand the true nature and value of that evidence (Boddington, 2015)”. It’s not uncommon for innocents to be convicted and guilty people acquitted because of digital evidence (Boddington, 2015). However, other factors can also affect the validity of the evidence, including: failure of the prosecution or a plaintiff to report exculpatory data; evidence taken out of context and misinterpreted; failure to identify relevant evidence; system and application processing errors; and so forth (Boddington, 2015). “There is a perception, largely undeserved, that digital evidence somehow alters the true nature of the original evidence and is therefore unreliable. Presented properly, digital evidence is capable of being of tremendous assistance to the courts (Hak,
During the comprehensive forensic examination Assante’s personal laptop was subjected to an eighteen hour intrusive search using specialized equipment to open and read all files on the laptop, scanning the unallocated space on the hard drive for deleted files, then proceeding to
Case Study 1: BTK In 2005, serial killer Dennis Rader, also known as BTK (bind, torture, and kill), was arrested and convicted of murdering 10 people in Kansas between the years of 1974 and 1991. Rader sent numerous notes to the police, but they couldn’t prove for sure that he was the one committing the murders. In 2004, he began sending things to the police once again. However, this time Rader sent a document created in Microsoft Word on a floppy disk.
When using the rules of Grammar and Forensic Linguistics I was able to analyze the email that was sent by David Nesteby and found many grammatical errors. The email has many spelling inconsistencies; also found the email a bit confusing; and the email contains suspicion of whether or not he is truthful. As an informant, the person should be able to create an email/letter with good punctuation and good spelling. The person receiving the email should be able to read it without having trouble understanding the problem.
Given that the industry spends close to 30 billion dollars on network security, the field of security operations should be more advanced. Josh discussed the importance of forensics in the world of security, and how analysis of a breach can lead to designing better security systems. Josh also equated the entire process of intrusion detection and response to that of a crime scene, which made it easier to understand the intricacies involved in security operations. Throughout the talk, Josh used analogies to describe security terms in terms of real-world concepts, which helped in better understanding the security operations.
With the introduction of new technology in recent years, the government can discreetly capture evidence from electronic files,
An example of a self-forensic tool used for digital extraction is Evidence Center by Belkasoft (Lun, 2012). Evidence Center can be used by investigators with evidence extraction of “messenger history profile, allocated disk space, unallocated disk space, RAM, Pagefile and Hibernation file” (Lun, 2012). When using this program, investigators are able to store all extracted evidence from the instant messenger into a database, which can be used to further analyze the data (Lun, 2012). However, this program isn’t successful in retrieving every type of information, such as pictures or videos (Lun, 2012). As a result, investigators would need to use an additional program while tracing the instant message
Bell states that the current legislation was drafted before the personal computer was developed and the Internet became so widely used by almost everyone (2002). It is important to increase this legislation and make it applicable in modern day in order to begin properly prosecuting those who have been using computers with unlawful intentions. After updating the current legislation to further define what computer crimes actually are and how a criminal acting in this behavior can be prosecuted, the next step is to find computer literate staff that is able to prosecute the more complex computer crime cases (Bell, 2002). If the prosecutorial expertise is not sufficient and the idea of what a computer crime is and how it can be defined in numerous ways cannot be understood on all levels, it will make prosecuting these criminals that much more difficult; which is why many of these individuals have not been charged or found with serious offenses due to the fact that there has not been an established state of how serious one computer offense is in relation to the law. Once certain procedures are established and the seriousness of each computer offense is fully determined as any traditional crime is, then the final steps into prosecuting individuals whom are caught misusing these computers can be prosecuted to the fullest capabilities of the law.
This area of computer science interest me because I want to fight crime on a cyber-level. My area of study is Computer Science, and later I hope to become knowledgeable in Network Security as my career. I plan to pursue a Master’s Degree that will place me on the path to this profession. One of the main reasons why this topic interest me is because of the excitement that it brings.
"Yes, I should have used two email addresses, one for personal matters and one for my work at the State Department. Not doing so was a mistake. I'm sorry about it, and I take full responsibility" (Gearan). As the current presidential candidate, Hillary Clinton stated on September 8th, 2015, she admitted to her mistakes for controversial email decisions in recent years. Hillary Clinton has been caught in a web of scandals during her political years, including when she wasn’t in political positions as her husband's scandals were involving her.
Computer forensics processes must adhere to standards set by the courtroom that often complicates what could have been a simple data analysis. In court, knowing who connected to the system based on logs is not enough. There must be facts that will support those connection
The following section will consider advantages and limitation of the first two mentioned types of digital forensics: Traditional (dead) and Live computer forensics. TRADITIONAL (DEAD) VS LIVE DIGITAL FORENSICS Traditional (Dead) Forensics In order forensic acquisition to be more reliable it must be performed on computers that have been powered off. This type of forensics is known as ‘traditional’ or 'dead ' forensic acquisition. The whole process of dead acquisition, including search and seizure flowchart and acquisition of digital evidence flowchart is shown on Figure 2 and Figure 3 respectively.
With the use of the computerized systems , computer data analysts have started helping the law enforcement officers and detectives to track crimes and to speed up the process of solving crimes. The detection of linked crimes is helpful to law enforcement for several reasons. Firstly, the collection of information from crime scenes increases the amount of available evidence. Secondly, the joint investigation of multiple crimes enables a more efficient use of law enforcement resources . Law enforcement needs to handle a large amount of reported, and the detection of series of crimes are often carried out manually.
