Computer Forensics And The Internet

When was the last time she accessed her computer? What is her background in computers, what is her skill level? I need some background on the former employee, her computer habits and activities prior to the files being found on her computer. I must collect digital evidence while keeping the data unaltered, first thing. This data will be used later in the prosecution of the case. This can be done through calculating and recording an evidence file. Next is imaging of the computer media with a write-blocking tool. I must keep the chain of custody. The computer's RAM is examined for evidence. During the examination step, verify and catalog the presence and integrity of the original evidence and any copies. An analysis is made with specialized equipment to find out exactly what's stored on the digital media. This includes a manual review of all materials found on the media, a review of the Windows registry, techniques to crack passwords and retrieve protected data, keyword searches and extraction of email and pictures for further review.

Digital forensics is an emerging discipline that focuses on the acquisition, recovery, documentation, and analysis of information contained within and created with computer systems. These methods and methodologies are used typically to figure out what happened, when it happened, how it happened, and who was involved.

Digital forensics is almost like observing someone’s complete psyche, you see that person likes and dislike. You are viewing their hates and love; you are finding things they don’t want to share with anyone else in the entire world. Using digital forensics is extremely perplexing with the obligation of interpreting the digital forensics that are located in an investigation.

The need for an increase in trained personnel in the criminal justice field with a sufficient level of knowledge and skills to investigate, detect, and prosecute high technology crimes is needed with the ever-increasing problem of technology crimes occurring throughout the world. Skilled investigators are needed to not only investigate and prosecute technology crimes, skilled investigators are needed to protect evidence found on computers and other portable devices so that arrests can be made. The most common form of damage or deletion of evidence is attributed to employee errors and omissions. Any organization that uses computers constantly faced with a “variety of potential problems that can lead to the disruption or, worse, destruction of

Computer forensics is the process that applies computer science and technology to collect and analyze evidence which is crucial and admissible to cyber investigations (Sindhu & Meshram, 2012). Adding the ability to practice sound computer forensics will help ensure the overall integrity and survivability of an organization’s network infrastructure (U.S. Cert, 2008). In this paper, we review a number of scenarios where computer forensics is necessary. We determine good sources of data for each scenario, and determine which would be optimal.

This paper will help explain the basic understanding of computer forensics. I will also identify five areas in computers and computer application a forensic investigator can look for digital evidence. I will identify three types of criminal investigations that can utilize the services of computer forensic investigators. This paper will help with the understanding of computer forensics.

To conclude with my case study, is worth to mention that in every forensic investigation is different and the circumstances and particularity of the case will conduct to the right forensic tools needed. Before start conducting a case every forensic investigator should gather how much information as possible from the suspected person or target system. In this case I focused my attention on my client's background information and technical knowledge of computer resources as well as security policies of her company and habits of usage. For all these reasons identifying the nature of the case before conducting any investigation will set the path and guide me in the selection of the best course of action to implement the right tools in my

Digital forensics is an ever changing field and the number of examinations being performed by digital forensic laboratories is constantly growing. Because investigations often rely on the results of these examinations, particularly those cases built on the digital evidence, investigators need to be able to provide results as soon as it is possible. To meet the growing demand and customer needs, ongoing research and development is needed in the creation of tools that will increase efficiency of digital forensic examinations. To improve efficiency and effectiveness in forensic processes, investigators should concentrate on specific areas including preparation and preservation, extraction and storage, examination and reporting, sharing, correlating

Criminalization is a social phenomenon, which has haphazardly increased in last few years as Information and Communications Technology (ICT) has become an internal part of our daily lives. Atomic computer users and large corporate companies are increasingly dependent on services provided by ICT. ICT provides wide range of services that are utilized by individual systems as well as enormous database handling companies. For numerous reasons, something is bound to go wrong within the ICT environments which may include an intentional attack on different services provided by an organization. Digital forensics has evolved significantly in the direction of prosecuting such criminals. Making use of freely available information on internet and rapid technological advancements in ICT has contributed to performing easy investigations rather cumbersome.

Digital forensics is the process of uncovering and interpreting electronic data for use in a court of law. The main goal of the process is to preserve any evidence in its most original form while performing a structured investigation by collecting, identifying and validating the digital information which will be admissible in a court of law. To collect the document has to follow certain guidelines. United States v. Gourde (2006) and United States v. Zeigler (2007) are both great examples of cases to investigate the case. The primary goal of this document is to demonstrate the importance of digital forensics in solving criminal investigation. In the following paragraph two criminal cases are studied and analyzed.

We live in the information age; the way people communicate and practice business has changed tremendously. Everyday new technologies such as: operating systems, applications and automated software make our lives easier. As computer technologies continue to grow, the necessity of securing private information has not been an easy task for computer networking administrators and information security teams. For digital forensic investigators, staying on top of rapidly evolving technologies had become an everyday challenge. Therefore, there are several factors that play an important role to be successful in digital forensics career. First, you must become familiar with the newly OS platforms. Secondly, continuous testing, evaluation and research could expand the capabilities of a forensic lab. Lastly, forensic investigators should maintain connections with a

Forensics is a very important aspect of criminal justice. When a crime is committed and there aren’t any witnesses to the crime, forensic evidence may be the only thing that prosecutors have to work with. The use of forensics also helps identify the perpetrators of various cyber-crimes. Forensic specialists can search databases, IP addresses, and recover documents to determine who is responsible for a crime. As a result, this makes forensic labs a necessary investment for an organization.

The current literature reveals a number of proposed frameworks, models and procedures that have been put in place in an attempt to formally describe an effective digital forensic investigation process. In digital forensic investigations, various processes focus on different actions performed, such as the data extraction, data examination, and data gathering and so on. Others tend to be more concerned with the analysis of the data extracted from the digital media.

Four sources of data that stand out for forensic investigators in most criminal investigations are files, operating systems, routers and network traffic, and social network activity. Each data source presents a variety of opportunities and challenges for investigators, meaning that the more reliable data collection and analysis activity typically involves examination of a variety of sources. Digital forensics must cover the four basic phases of activity, which include: data collection, which describes the identification and acquisition of relevant data; data examination, which includes the processing of data through the use

Throughout the length of this paper, I am going to be discussing the topic of computer forensics. Computer forensics involves carefully collecting and examining electronic evidence that not only evaluates the damage to a computer as a result of an electronic assault, but also to recuperate lost information from a system to prosecute a criminal in a court of law. Since security is such an important factor in technology, it is crucial for any type of computer professionals to understand the aspects of computer forensics.
