Computer forensics is the process of using the latest knowledge of science and technology with computer sciences to collect, analyze and present proofs to the criminal or civil courts. Network administrator and security staff administer and manage networks and information systems should have complete knowledge of computer forensics. The meaning of the word "forensics" is "to bring to the court". Forensics is the process which deals in finding evidence and recovering the data. The evidence includes many forms such as finger prints, DNA test or complete files on computer hard drives etc. The consistency and standardization of computer forensics across courts is not recognized strongly because it is new discipline. It is necessary for network …show more content…
In the current situations computer forensics should be taken as the basic element of computer and network security. It would be a great advantage for your company if you know all the technical and legal aspects of computer forensics. If your network is attacked and intruder is caught then good knowledge about computer forensics will help to provide evidence and prosecute the case in the …show more content…
Organizations have developed security devices for their network like intrusions detection systems (IDS), proxies, firewalls which report on the security status of network of an organization. So technically the major goal of computer forensics is to recognize, gather, protect and examine data in such a way that protects the integrity of the collected evidence to use it efficiently and effectively in a case. Investigation of computer forensics has some typical aspects. In first area computer experts who investigate computers should know the type of evidence they are looking for to make their search effective. Computer crimes are wide in range such as child pornography, theft of personal data and destruction of data or
It is the computer forensics job to look through all of the computer files, even the deleted ones, to see if there are any incriminating files that would prove them guilty. Even reporting them to the jury is one of the jobs that a computer forensic person might have. Not only does this community work closely with eh police force, they can also work within the FBI or a company that uses computers in their business like Apple. Th...
Digital Forensic is the process of uncovering and interpreting electronic data that can be used in a court of law. It requires a set of standards to show how the information that is gathered, preserve, and analyzed is strictly followed. The analysts need to understand the evolution of the current technology and how it will impact how they gather their information. The investigator is able to uncover evidence and analyze it to gain the understanding of the motives, crime, and the criminal’s identity to help solve the crime. As computers and technology continue to become a part of our everyday lives, the cyber realm contains a growing realm for evince in all types of criminal investigations (Cummings, 2008) Digital forensics is a way to connect information security and law enforcement. It ensures that the digital evidence is collected in a way that it can make it into the courts in an unhampered or uncontaminated way (Dlamini, M., Eloff, J. & Eloff, M., 2009).
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.
Technologies are advancing in today's world where more information is being generated, stored and distributed through digital gadgets. This requires investigators and forensic expert to increase the use of digital evidence gathering as a tool to fight against cyber-crime (International competition network, n.d.).
Forensic psychology is one of the newest sections of psychology and has been recognized by the American Psychological Association (APA). Psychology is known as the science of mental processes and behavior. The term forensic means different scientific techniques and tests that correlate to a discovery of a crime. When combining the two together, forensic psychology can be defined as “The use of psychology in evaluating mental processes and behaviors within the application to several justice systems” (Bartol & Bartol).
Forensic science, what is it exactly? Forensic Science is any aspect of any area of science that could be called into question in a court of law, as it relates to the law (http://home.earthlink.net/~thekeither/Forensic/forsone.htm). There are different areas of forensic science, and different jobs that people do. There is the crime scene investigator, as shown in the hit television show CSI: Crime Scene Investigation. They search a crime scene, collect evidence, tag/bag evidence, and analyze it. Forensic photographers take pictures at crime scenes. Forensic psychiatry and profiling is where you diagnose and treat people with mental illnesses, and where you make a personality profile of the criminal from gathering information from the crime scene. And firearms and toolmark identification, another type of forensics, is matching bullets to guns, explosives, and other weapons. These are just a few of the many different positions and jobs out there that deal with fore...
The transitional growth in the forensic science sector has not been without challenges. Though the world has experienced increased capabilities and scientific knowledge, which has led to faster investigations and results, many forensic experts have argued that forensic laboratory testing, in the light of 21st century technological advancements, is yet to meet the expected rate in quick available testing and analysis (Mennell & Shaw, 2006). This is with respect to the growing rate of crime and the high demand of quick crime scene testing and analysis. In the science of crime scene, analysis and interpretation of evidence is majorly dependent on forensic science, highlighting the change in the role of forensic sciences (Tjin-A-Tsoi, 2013). In the business of forensic science, time is beginning to play important role in the evidence testing and analysis which is becoming crucial in reducing ...
Forensic science is any scientific field that is applied to the law of science. ("Bloodstain Pattern Analysis.") There are 5 groups within forensic science that also have more categories within them. Those being physiological sciences, social sciences, forensic criminalistics, digital forensics and other disciplines. Forensics help locate the attacker or anyone involved in the
Forensic evidence can provide just outcomes in criminal matters. However, it is not yet an exact science as it can be flawed. It can be misrepresented through the reliability of the evidence, through nonstandard guidelines, and through public perception. Forensic science can be dangerously faulty without focus on the ‘science’ aspect. It can at times be just matching patterns based on an individual’s interpretations. This can lead to a miscarriage of justice and forever alter a person’s life due to a perceived “grey area” (Merritt C, 2010) resulting in a loss of confidence in the reliability of forensic evidence.
The use of computers in homes, schools, offices, and other places has increased in the past few years due to technological developments. As computers have become important components of modern communication, their increased use has also led to the emergence of computer crimes. Computer crimes basically involve the use of a computer system to carry out an illegal activity. In attempts to lessen the frequency and impact of computer crimes, law enforcement agencies use computer forensic to investigate these offenses. Actually, computer crimes are governed by specific laws and dealt with through conducting a computer forensic investigation (Easttom & Taylor, 2011, p.337). Notably, a computer forensic investigation is usually carried out through the use of computer forensic tools, which help in collection of evidence based on the specific offense.
Presently, because the importance of digital forensics it has its own field of computer forensic expertise, training and certification.
We do have known what forensics is. Forensics that we know is an application of various sciences to answer questions that are important to legal system in which it may be related to a crime. Forensics generallu covering something or methods of a scientific nature and also the rules established from the facts of the event, to do an introduction to physical evidence. This is just a usual forensics. Nowadays, forensics is not just like that, digital devices are everywhere today, helping people to communicate with other people globally, not just between town. We can use that to do some forensics thing too, and find the evidence. It is called Digital Forensics.
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 due to privacy issues, the new technology has made investigations and prosecutions well organized and effective.
The biggest challenge investigators face and who is involved with high tech crime is the fast-paced constant evolving nature of technology. When companies come out with new devices or new versions of old devices which is almost all the time, and those who gather digital evidence must remain current to be able to locate and preserve all potential evidence. As technology evolves the capacities of these devices will rapidly increase while their form factor grows continually smaller. Investigators must preserve digital evidence to make sure it is suitable for presentation in court as well. Investigators must first never change a crime scene or alter evidence. It is their goal to document and preserve the scene exactly as it was when the crime occurred. Extreme caution and care is needed because the mere act of documenting or cataloging a crime scene means that investigators are interacting with the scene. The second concern is the physical fragility of the evidence. Care must be taken to keep items from getting wet, stepped on etc, this can also be applied to digital evidence. Investigators have been able to examine hard disk drives that have been through fires because the drives are usually air and water tight and impervious to temperatures into the thousands of degrees. The third issue is that digital evidence can be lo...
“The word ‘forensics’ means “connected with the courtroom”; so forensic science is, therefore, concerned with gathering hard evidence that can be presented in a trial” (Innes 9). Forensic science is a science that is applied specifically to legal matters, whether criminal or civil. “Few areas in the realm of science are as widespread and important as forensic science” (Hunter 12). Forensics is the one science that is most commonly used in everyday life. It is also a branch of science that incorporates other branches of science such as biology, chemistry, and etc. Since it is used almost every day “No one can dispute the importance of the contributions to society made by forensic science; the ability to solve crime is undeniably important” (Hunter 13). Forensic science has given criminal investigation a new edge. “Advances in science have opened the door for more effective evidence discovery, howev...
