Forensics For Technology – What Is It?

Forensics technology has become a broad field of investigation that refers to the scientific evidence used in criminal cases. This physical evidence is comprised of scientific collection, and its analysis. There are many new aspects of this type of technology geared toward evidence or establishing facts to be used in civil or criminal proceedings.

One of the technical areas that have much to offer is digital software. Criminals and terrorists have the opportunity to use a wide variety of electronic devices in their crimes. As crimes with a digital component are on the increase, it is necessary for law enforcement to have the equipment to counter these crimes. Digital forensic software has the capacity to recover data from a computer that has been reformatted or repartitioned

Other applicable software programs:

• A program capable of wiping a hard drive clean
• A spy type of software can locate hidden partitions, plus, quickly process large hard drives, and more.
• Images can be compresses into “flat” images from floppy disks for analysis
• A “partition manager” that examines all partitions on a hard drive and can switch them around or even hide them
• A new write blocker program protects computer information more effectively than past programs

The science which interprets image content is forensic image analysis. Several companies have produced efficient equipment that cut cost and speed up investigations. The equipment is designed to do comparison photography, analysis the content, photogrammetry (using photographs to make measurements) and to authenticate the image. Through a variety of techniques, mega data, pixil aspect ratios,and errors are utilized to extract information from video, photographs and animations. This is effective even when an individual has attempted to clock the evidence.

One of the newer tools is video forensics, which is primarily the scientific examination and evaluation of multimedia evidence in legal matters. The goal of this technology is to produce an accurate picture of evidence for a judge and jury to help determine the verdict in a civil or criminal case. In addition, this technology uses processing techniques to enhance video footage, refine grainy photographs, and to enhance a particular person or an object in a video footage, plus it converts digital video into specific formats for forensic analysis. This type of work is important in solving cases for law enforcement, security, surveillance and even military operations.

Data recovery is a process used for legal purposes to retrieve data from computers. It is much more difficult to erase all the information from a computer than most people realize. The purpose of data recovery is to retrieve lost or deleted information. The mined data is done using a process of collection, analysis, and then preservation. With the successful completion of these steps the computer expert will have the lost data to present to the court. This technology may be used in civil or criminal proceedings to provide evidence for the court.

If forensic describes evidence that can be used in court, then it also must cover the technology and science necessary to provide this evidence. A forensic investigation is conducted in a lawful manner, establishing facts and evidences that have been thoroughly examined, keeping in mind the chain of custody, to be presented in a courtroom. Subdivisions that exist under this area of investigation are firewall forensics, database forensics and mobile device forensics.

Computer Forensics Expert

The field of digital forensics is one that hasn’t received much press, until lately. With the onslaught of social networking sites, email/internet abuse and criminal cases involving computer files, almost everyone has a use for a computer forensics expert.

This field is thriving but it’s not one that a person can just jump into. Computer forensics is a very specialized field that requires years of experience and education in order to be successful.

There are many good schools one can attend, or even the military would be a good place to receive proper training. The skill set is much different than you might expect and you really don’t know what is involved until you start working. Even the most computer savvy individual wouldn’t do much good for a digital forensics firm on their first day of work.

Many people start off by finding internships, whether they went to school or not. You are much more likely to receive a good internship straight out of college but being at the right place at the right time doesn’t hurt either. Be persistent with a company that is offering any kind of position as on the job experience is really the only way to break into this field.

A computer forensics expert could be asked to do a large variety of jobs on several different types of cases. A large area of employment is from the police force. Forensics experts are brought on when a case involves anything with a computer, phone or other electronic devices that store and send information. Many of the cases involve sexual crimes and the illegal solicitation of pictures across the internet.

When a computer forensics expert comes in they first assess the case and establish what needs to be done. Once this is determined the acquisition of evidence starts. Forensic images are created of the relevant media to preserve and maintain the integrity of the evidence. Analysis then begins and all key evidence is determined and a strategy is put together. A report is generated to properly explain what information was found and how it is pertinent to that specific case. If needed, a digital forensics expert will be able to testify in court in a clear and concise way that benefits the client.

One can make a pretty good living doing solely criminal cases as once you become knowledgeable about court proceedings and how to properly handle yourself in a court room you will become a valuable commodity to many. Of course, it depends on your success rate and how well you are able to access relevant information on the job, but the right demeanor in court can take you a long way.

Many computer forensics experts don’t want to be in the spot light so they choose to refine their skills behind the scenes. Becoming proficient in the acquisition and analysis stages of a case can set you apart from the rest of the field. There is no set way to operate and finding new techniques and strategies will prove you to be a well respected professional in the field.

How Digital Forensic Services Help Companies

It’s no secret that computer-facilitated crime, or “cybercrime,” is one of the major problems in today’s business world. However, many businesses are unaware of both their vulnerability to cybercrime and the steps they can take to minimize their exposure to such malicious acts by outsiders. This short article will explore some areas of concern that can be addressed by hiring a Digital Forensic Services (DFS) firm.

Having a network that is well-protected against both external and internal disruption should be a goal of every business. Hiring an experienced DFS firm, one that has seen “all the tricks” used by those that would attack a business network, is an ideal way to implement and maintain a high level of network security.

All DFS firms can conduct a wide variety of simulated computer attacks against a network to determine that network’s security level. Once an attack has occurred, a DFS company is often able to “backtrack” to the attack source by using resources such as system logs and Internet Service Provider traffic records.

A secure computer network is vital in the protection of intellectual property such as original research and prototypes of software applications. An evaluation by a DFS firm can help provide the level of security appropriate to any business operations.

It is common for an intruder to leave behind files or malicious programs that will attempt to associate a business with unsavory business practices. This is often done in order to “sabotage” a business’s reputation with its suppliers and/or clients. In such instances a DFS firm will often be able to pinpoint the date and circumstances under which such events occurred and demonstrate that an outside entity was responsible for its presence on the victim’s computer system.

One of the basic “rules” of digital information technology can be summarized as follows: “Given enough computers, and enough time, someone will eventually do something stupid and crash the computer that contains the data most essential to normal business operations.” A DFS company can usually recover such data within a few days and, more importantly, how to take steps to prevent similar instances in the future.

Many hackers are members of criminal elements that operate purely to profit from stolen business data. Many of these elements recognize that there is little likelihood that they will face criminal prosecution simply because evidence of their crimes that would be “left behind” would not stand up in court. Since most established DFS firms meet or exceed the most stringent federal standards recommendations, they will provide services whose techniques will satisfy all legal requirements related to the processing of evidence.
