How Computer Forensics Analysts Work
How Computer Forensics Analysts Work
Thanks to television shows most of us already have an idea of what forensics is. Although some scenes are not depicted correctly (examining specimens are more exhausting and mentally draining due to the constant demand for paying attention to details, they don’t look as easy as they are in television with swooping camera angles) they have given us an idea on what they do in collecting evidence.
Computer forensics is part of this investigation. Due to the higher incidence of cyber crimes they are now an essential part of the legal process.
We already have an idea on what they do. However a computer forensics job entails a lot of procedures and expertise. Like any other evidence electronic data can also be fragile and damaged. There are certain steps to be followed to ensure that the data will be collected without being tampered.
A day in the work of a computer forensic analyst
The first thing that an analyst will do is to secure the data and the machine. The data can never be analyzed in the same system that it came from so exact copies are made. Usually the data in a hard drive is duplicated to extract the information needed.
The collection process starts when the analyst examines the surroundings of the machine. Other physical evidence such as notes, disks and printouts are also taken. Photographs of the surroundings are also taken. The area is also examined for portable storage devices.
If the computer system is still operating the information will be collected by examining its applications. Computers that are used for illegal communications may not have all of the data stored in the hard drive. Information stored in Random Access Memory will be lost if the computer is shut down so this step is important.
Open source tools are used to analyze on live computers. Analysts can also obtain an image of mapped drives and encrypted containers while they are on. The data from network connections are captured first, then running applications, and lastly from the Random Access Memory.
The computer is then shut off carefully in a way that it will not loose any data. The method used will depend in the computer and the operating system it uses. If proper shut down is made volatile data can be lost. Pulling the plug is not advisable either because it may corrupt the file system and loose important data.
The analyst then inspects for trap and photographs the configuration of the system. A diagram will also be made including serial number and markings.
The analyst then makes an exact duplicate of the hard drive called Imaging. They often use hard drive duplicators or software imaging tools. This is done in sector levels to make bit-stream copies of ever part that is accessible to the user which can store data.
The original hard drive is then installed with a hardware write protection and sent to a secure storage. After making a complete and accurate copy the duplicated data can now be analyzed for evidence. Analysts use algorithm to make sure that the imaging process is verified. Two algorithms are generally used in this process.
The analyst then renders his opinion then documents everything that was done. A report is made that contains all the findings of the analyst and whether or not it has been used in an illegal activity or criminal act.
Ergonomics At Work Osha Is On The Job
Ergonomics At Work Osha Is On The Job
The French poet Charles Baudelaire observed back in the 1800s, “Inspiration comes of working every day.” Most people do work every day, and unfortunately it’s not only inspiration that comes of it. Repetitive stress injuries (RSI) are also the result of every day tasks performed again and again while operating a computer. Relief is in sight, however, thanks in part to a particular government agency. This organization is raising awareness and promoting solutions 24/7.
The Occupational Safety and Health Administration (OSHA) has a mandate to protect employees from being hurt in the workplace. James Hodgson, Secretary of Labor, established OSHA within his department in 1971. This was in response to the Occupational Safety and Health Act, legislation he helped author. For the first time in U.S. history, the government stepped in to make sure that workers were as protected as possible from illness, injury, and death on the job. And OSHA had its work cut out for it. Construction, chemical, and agricultural workers were among the many who needed better safety standards in their industries.
But as computer use rose, and the related RSI grew, OSHA turned its attention to this new problem. In recent years, OSHA has developed a four part program designed to reduce injuries and illnesses associated with computer use on the job. The four parts are
Guidelines, Outreach and Assistance, Enforcement, and the National Advisory Committee.
Guidelines are recommended practices that are developed for specific tasks and industries. These are voluntary, not mandatory. Employers use the guidelines to identify and modify risks in the workplace. Implementing these practices reduces injuries related to the way people do their jobs.
The Outreach and Assistance component of this program is aimed at businesses of all sizes. OSHA wants companies to take a proactive stance when it comes to preventing RSI. To help employers, OSHA designed an extensive array of tools that educate, analyze, and train people regarding the ergonomics of their jobs. Available to the public for free on the OSHA website, the computer workstation portion of the Ergonomics eTools is a comprehensive guide to proper computing techniques.
Included in this section is:
Good Working Position (talks about every part of the body and what the best placement is for preventing RSI)
Workstation Components (all the technology and furniture you commonly use is listed here with possible hazards, solutions, and tips)
Checklist (a great way to evaluate how you’re doing ergonomically while you operate a computer)
Work Process (focuses on the physical movements of computer use, with hazards to watch for, more solutions, and tips)
Workstation Environment (information about factors people often don’t think about such as lighting, ventilation, and glare)
But Outreach and Assistance is more than the Ergonomic eTools. It has industry guidelines, cooperative programs, ergonomic analysis info, and success stories. It even has a checklist with tips for new purchases. It is chock full of valuable information for everyone from the individual computer user to the captains of industry.
OSHA persists in its campaign to help employers and employees prevent Repetitive Stress Injuries. If the folks at OSHA have their way, inspiration will be the only result of long hours of work in front of a computer. Baudelaire would approve
