Introduction Computer forensic specialist use different types of methods to try and exploit the required media they are trying to investigate. Computer forensics is the application of investigation and analysis techniques to gather and preserve evidence from a particular computing device in a way that is suitable for presentation in a court of law. Cyber analyst’s ability to understand the different types of networks, configurations, packets, computer attacks, MAC addresses, and sniffers is critical in the ways to exploit cyber criminals. This is an emerging field of law enforcement and is becoming essential in catching criminals of all kinds. Additionally, large companies have begun to hire cyber experts to ensure data theft and networks …show more content…
Many types of networks exist such as Local Area Network (LAN), Wide Area Network (WAN), Wireless Local Area Network (WLAN), Metropolitan Area Network (MAN), Storage Area Network (SAN), Cluster Area Network (CAN), and a Personal Area Network (PAN). LAN and WAN are the two types of networks that are most primarily used. A LAN utilizes network connected devices at small or short distances. An office, schools, or homes that do not span large distances typically utilize a LAN. A small LAN only utilizes two computers while others can use up to 1000 computers. Wide area networks or WANs cover large physical distances and can be seen as far as anywhere on the globe. A WAN acts as a LAN in many different connected locations. However, a WAN is not owned by just one organization but can be collectively owned and used by many organizations. Next, a virtual private network or VPN acts like a private network extending its ability to act privately across a public network. This sends data secure and encrypted between to computers therefore creating a point to point connection that may be left undisturbed. A benefit of this is that VPNs can be accessed remotely and save resources across an organization or at home. Technology has produced different types of networks for the different uses required by the processes required. Multiple configurations can be set up on a network which will allow a system administrator to obtain the desired network objective. When
A job as a computer forensics expert combines the best of crime fighting and technology. A computer forensics expert is responsible for collecting and analyzing evidence from data storage devices, computers and networks to investigate a computer crime. They will typically work with law enforcement officials to collect evidence for legal cases and serve as expert witnesses. A computer forensics expert may work with the government, legal firms or law enforcement. Individuals who want to succeed in this field must have knowledge of forensics software, cryptography principles, eDiscovery tools and multiple programming languages.

A Wide Area Network ( WAN) is a computer network covering multiple distance areas, which may spread across the entire world. WANs often connect
contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers.
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
“CHFI investigators can draw on an array of methods for discovering data that resides in a computer system, or recovering deleted, encrypted, or damaged file information known as computer data recovery (“Computer Hacking”, n.d.)”. A person who is a certified Computer Hacking Forensic Investigator has the skills necessary to identify an intruder’s footprints and to properly gather the necessary evidence to prosecute in the court of law (“Computer Hacking”, n.d.).
Description: Computer forensics investigators may provide services, from investigating computer systems and data in order to present information for legal cases to help catch hackers and cyber criminals. They are the law enforcement agents in the cyber world. They also work closely with detectives to help convict criminals who have left a digital trail during their crimes.
VPN configurations will be used between each location to ensure site-to-site connectivity. The VPN will allow employees to access the company's intranet from home or while traveling outside the office, and site-to-site VPNs allow employees in geographically disparate offices to share one cohesive virtual network. A VPN can also be used to interconnect two similar networks over a dissimilar middle network; for example, two IPv6 networks over an IPv4 network.[6] which will
The aim of this report is to examine Computer Forensics and Anti Forensics in details, investigation and Analysis techniques, and standard set of procedures which Forensics investigators must follow
Computer forensics is a new area of crime investigation. However, it is an area of knowledge that is growing at a faster rate. Computer and network forensics investigators are professionals who are mainly trained on various investigation activities related to computer crime. They are trained on how to investigate computer crimes
Technology has enhanced within the years into solving complex crimes using efficient techniques or tools conducted by a special task force to protect against possible undesirable events. For example, cyber-crime is through the use of computers and information systems that potentially access another’s computer without authorization that may have a corruptive effect, especially on the mind downloading illegal material used for personal gain emphasizing necessity. However, the technological communication efforts are databases built to conduct special task force assessments to stay current with the ongoing criminal activities that develop the usage of the technological information systems without authorization. These databases affect the communicating of information in a way to move faster and efficiently to conduct the arrest of a suspect, to obtain warrants, and to locate a criminal. In addition, the databases provide factual information to conduct further investigations and apprehensions helping the worldwide justice system to become more effective giving those faster results by means of communicating through the new innovative database technological systems. The cyber-crime unit will conduct an extensive investigation through the usage of the new
Investigating a cyberstalking case presents a unique set of challenges. Evidence can be found in digital form, so it can be protected from being lost or damaged, or the complete opposite can be true and it can be easily lost, damaged, corrupted, or rendered inadmissible in court due to flawed forensic gathering practices. It is important, with cases involving digital media that the same procedures be followed when it comes to collecting evidence. Chain of custody documentation must still be kept. The right software must be used to directly copy any hardware seized or searched for investigative purposes.
In this essay I will be talking about the key guidelines when it comes to investigating computer related crimes, such as what kind of the sections and sub-sections the offence falls under when regarding the ‘law’. I will also analyse the principle that will apply when dealing with the collection data using the digital forensic unit to analyse the data, more so how this is used to make accurate judgment on why the data was in this location and what its purpose or intended use was. Furthermore I will address what kind the authority the ACPO are granted, and further dissect the responsibilities the chief commissioner has. Lastly I will be addressing one the biggest computer related crimes which Cyber Crime and how ACPO created a method for dealing with such crimes, such as dividing the crime into two different categories of Cyber Crime, and how they differ from one another.
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.
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.
