Most small to mid-size corporations cannot afford a complete Computer Emergency Response Team (CERT). A lot of large outsource this operation as well. The team being internal or external makes a significant difference in the first stages of an investigation. We will assume that we are working as a forensic contractor. Given the most opportune situation our forensic team should consist of multiple job titles, but some of these may be held by the same person. One very important position is a legal representative. This may come from within the public relations department of the company that has hired you, but it is usually a good idea to have someone with extensive legal knowledge to guide in the process and ensure the data is admissible in court. There should be CERT team leader that coordinates and reviews all of the actions of the team. Each incident should also have an incident lead. This incident lead may vary depending upon the type of intrusion, or the CERT leader may be the incident leader as well. You will also have CERT members that specialize in various areas. This may include IPS and IDS experts, specific operating system experts, and/or web server experts (“Responding to IT Security Incidents). The response plan should be in place prior to any incident occurring. This should include a forensic tool chest, a mobile one is best if possible (all tools need to be tested prior to use). The plan typically follows a general form for most incidents and most organizations. The incident is reported. The initial assessment is made, including information in regards to the network. The investigation then begins with evidence gathering based upon the type of incident and information we already know from our initial as... ... middle of paper ... ...oi: 10.1016.

There is a wide range of Linux forensic software available. There are single tools like file carvers, or there are comprehensive collections of tools. In the following, some of the most popular Linux forensic tools are described. The focus is put on The Sleuth Kit because it is organized according to the different filesystem layers. This provides an interesting insight on how forensics is done on filesystems.
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what

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
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 Forensics Thesis: Most organizations rely one way or another, on information technology, this has led to a significant amount of development as well as uncertainty. Digital forensics is a growing field with much diversity in the technologies in which a professional can specialize. “Digital forensics can encompass many areas of inquiry; court applications of digital forensics can include any aspect of computer science or information science” (Taylor, 2014). I. Introduction Computer forensic is the science of identifying and recovering data from a device or computer without altering it in any form. It is often used in litigation to preserve electronic evidence.
Figures A3. Benefits The benefit of computer forensics include a number of things. The most important advantage, however, is that it is able to search through a large and massive amount of data, and it has the ability to do this very quickly. Computer forensics can be used in corporate fraud, breach of contract and asset recovery, theft, and intellectual property disputes.
This book is relative to digital forensics because it demonstrates the broad scope of cyber and computer crimes. The crimes discussed consist of hacking, financial fraud, child exploitation, phreaking, identity theft, etc. The various methods used by criminals to commit said crimes is also discussed and how these methods are evolving and becoming more efficient. The book is relevant because it demonstrates how expansive cybercrime, computer crime, and digital forensics actually are. The book discusses hacking and although that seems to be a straightforward topic, there are various types of hackers and methods that they use that re
When digital forensics was first established, investigators relied on smaller amounts of data-using storage devices to analyse evidence. At the time, digital platforms were much simpler to understand and there was a limited number of devices that could be used as evidence. However, today analysts are tasked with investigating countless amounts of emerging problems that are surfacing (Huebner et al., 2007). These problems require an unprecedented amount of testing and analysis to establish a foothold in cyber-crime. It is not enough to simply assess the developments made in
Digital forensics, sometimes known as digital forensic science is a branch of computer forensic science encompassing the recovery and investigation of material found in digital devices, often in relation to computer cyber crime. Information and Communications Technology (ICT) working environments are experiencing increased computer use for other than work-related reasons. User activities may include but are not limited to browsing the Internet for private purposes and using online search engines for work-related information. As ICT has grown at the same time advances in social networking, mobile technology, cloud computing and storage solutions have increased the information flow within organizations.
Jessica Jenkins Professor Coutras CSIT 100-33 June 4, 2015 Computer Forensics When someone commits a crime, there are teams that are put together in order to analyze, interpret, and extract data from evidence found at a crime scene. In certain investigations, such as intellectual property theft, industrial espionage, fraud, and even in inappropriate email and internet use in the work place, the team who specializes in extracting data from electronic devices are called computer forensic analysts. When evidence is stored digitally, computer forensics is essential in bringing that evidence to the court while maintaining it’s integrity. To do so, they need to follow a set of guidelines. Those guidelines help ensure the evidence will hold up in
Future aspects of computer forensics By steev ray Dec 7, 2012 Computers have become more prevalent in the existing modern society. There is huge rise in the computer crimes across the world. With the rise in computer crimes, there is the urgency to have computer forensic specialist to investigate the crimes and demands of computer forensics has grown up. Its needs are felt in all the local, federal, state and modern law enforcement agencies. It is important to identify and take necessary action against who engage in such crimes.
INTRODUCTION Quality is the most important trait that I struggle to achieve when engaging in academic research. Quality research is achieved through: identifying academically and practically relevant research questions; thorough theoretical development; methodological rigor; and good writing. When successful in these areas, publication in high quality journals results. This benefits the author, their academic institution, and the journal. BODY
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.
