Computer Program Staging Areas

Many a time we software engineers want to peek into a window at what the status of a product is within computer code. For example if the article in question is a blouse, on the computer end, an engineer might want to test his software to make sure he is allowed status updates. After all, he wrote the program to process the ordering of, sending to and receiving of each garment for a particular department store that employed his programming services.

Let’s say our software engineer is a typical guy named Mike. His supervisor, a guy named Cesar wants to know where at different points in the journey that that blouse in question embarks on starting from the store inventory and ending in the customer’s house, what the status of it is. Mike has a particular programming style where he will stage that status entry/value in a particular memory space.

In other words through the Internet, the customer will be able to access the program to order the garment she wants and at the same time, a behind-the-scenes manager can access that same program to complete a status report for any particular garment in the system.

When people talk about front-end code in relation to the main body of code, they mean the software that is accessing the main software program to attain products. The back-end code ties into that same body of main code (the exact same one) for inventory tracking and analysis purposes.

For example, let’s make memory spot 0x20f60 our staging memory location. We would simply start out with a list of status option labels. They would include: Color of the Garment; Size of the Garment; Quantity of the Garment in question; Name of the Purchaser; Address of the Purchaser; Price of the Garment. Given these six starter parameters, Cesar, Mike’s boss would choose one to learn the status of one of them.

He would have a pull-down menu titled Status Parameters. Then each of those six parameters would pop-up in that drop-down menu and upon choosing one of them, Cesar would get the status in regards to that particular parameter. For example, if he chose Color of the Garment, the status return might read PURPLE. For the Size of the Garment, the status return might be X-LARGE. The magic of this programming is that each status word will be staged in memory spot 0x20f60, making it convenient to add more parameters at any point.

This programming style of having an exclusive memory spot to stage status values is not only convenient for our software engineer Mike, but it’s also useful for designing behind-the-scenes-back-end-code for our supervisor Cesar.

Forensic Toolkit – What’s in It?

In the world of digital forensics, the well prepared investigator needs a forensic toolkit. The tools that this person will use will help her or him gather evidence of white collar crime or fraud, document the evidence of the occurrence, and, perhaps, place that investigator on the witness stand for expert testimony in what ever legal proceedings come out of the process. The tools used by these investigators are primarily software tools, though there are a few hardware considerations as well.

The basic computer forensic toolkit will probably be contained on a CD or DVD and be presented primarily in a word processing format. Any computer forensic investigation produces a mammoth amount of paperwork, since the goal of the investigation is to document absolutely everything that is found. These toolkit CD’s are designed to supply the investigator with tried and true forms and templates that will allow to investigator to document everything that is found. They also serve as an effective check list to aid the investigation team in ensuring that no step is missed and that everything is done in the correct order.

Another major component of the toolkit will be templates and tools to assist in the presentation of the findings of the investigation to management. It is vital that all findings be reported in a manner that is professional, unbiased, complete, and scientifically sound. This is the end product of the investigation, and what management sees as being what they paid the investigators to actually do. This reporting may also end up being the basis (and exhibits) of the legal proceedings that may arise from the process, so it is vital that these reports and presentations be accurate, clear, and completely aligned with the law.

The main non software tool that is used in a computer forensic toolkit is an imaging device. Making an exact image of the hard drive (or other storage medium) of the computer is the most common first step in the capture of data. It is absolutely required that a “clean” copy of the computer’s memory and stored data be in place, so that the investigators are sure that they are looking at and analyzing the data in the same precise pattern in which it occurs on the computer in question. There are many brands of device available, and they all have the same basic function.

First, these devices must make an exact copy of the data. Secondly, the usually perform the copy at the sector level of the disk as a bit stream process (as opposed to a simple file copy process). This method makes a more complete and accurate copy of the data, which, in turn, allows for a more thorough and accurate analysis.

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.
