Iso 5725 Criteria For Computer Forensics

724 Words3 Pages

The very first step after identifying and selecting the required computer forensics software our company needs, we need to test, verify, and validate the software otherwise the evidence we present would not be admitted in court. In the company, one of our main goals is to always follow the established standards set by federal agencies. For this purpose, when planning our procedure to validate our software, we must meet the standards set by the National Institute of Standards, and Technology, also known as NIST, which creates procedures and criteria for testing and validating computer forensics software and tools. In order to verify, test and validate the forensic software the company will be using we need to meet the criteria established by NIST in 2001 based on standard testing methods, the ISO 17025 criteria for items that have no current standards and the ISO 5725 criteria. ISO 5725 specifies that the results must be repeatable and reproducible. In other words, repeatable refers to obtaining the same results when using the tool in the same lab using the same workstation, while reproducible refers to obtaining the same results when using the tool in a different lab using a different …show more content…

The way the operating system and the forensics tools perform can be affected by new upgrade and patches. After a new upgrade is released, it first needs to be tested in a different workstation to determine if is reliable. In case the upgrade is not reliable and affects the performance, we need to file an error report to the vendor of the software in which they should be able to address the problem by releasing a new update, which we must test again to verify its reliability. Is important to know that the workstation used to test the upgrades needs to be built with the single purpose of using the tools with the newest

i. Manage The term manage is used to mean acquiring the necessary contractual vehicle and resources that include financial resources that are used in running forensic labs and programs. It can also be used to mean to coordinate and build internal and external consensus that can be used to develop and manage an organizational digital forensic program. Management also is to establish a digital forensic team, usually, the one that is composed of investigators, IT professionals and incidents handlers to perform digital and network forensics. Management provides adequate workspaces that at minimum take in to account

You need to do it in many difference phases you want to insure that the integrity of the computer evidence. You should copies all the files onto a write once only CD- read only memory disks. You may want to “ clone” your computer hard drive, you would do this, because you would not want to mess up the hard drive that was on your computer. This also means that you would be copying everything this will including the operating software.

4.7.5 Data Preservation and Isolation from the Network. The main purpose of a digital forensic report is to keep the data integrity, avoiding any type of data alteration, in order to present valid evidences, for instance in a court. The use of not valid software to check the stored information in a mobile phone can alter these information. The action of receive new data can alter the information stored, for instance an automatic firmware update, or remote device control with the risks involved. Therefore, it is extremelly important have the device completely isolated from the network.

Computer Forensic Investigation Final Research Paper Phuong Le CJCU 405 Professor George Ackerman May 3, 2015  Abstract Computer forensics, also known as digital forensics is an emerging field of rapid development, involving the collection and analysis of evidence from computers and networks. Because computers and the internet are the fastest growing technology being used for criminal activities, the need for computer forensic experts will increase in the coming years. A computer forensic expert works involved examine the computer media, programs, data, and log files on computers, servers and networks. Many agencies employ computer forensics, including law enforcement, criminal prosecutors, military intelligence, insurance agencies,

Once the evidence has been properly collected, the CSIRT will perform the forensic analysis to determine the type of crime that was committed (Sindhu & Meshram, 2012). Since NJVC is a contracted company for the Department of Defense, there are many crimes that could pose a significant risk to both NJVC and their customer. In order to protect these two entities, it is critical that the forensic team accurately determine the crime(s) that were committed on NJVC’s

Jurors are usually everyday civillains and lack the technical expertise to fully grasp the complexity of digital evidence which can cause misunderstanding and sway the decision of a trial. This problem is heightened by the perception television places on jurors as they often oversimplify the effort that goes into digital forensics. Jurors may have the connotation that results are instant and that sophisticated techniques shown in shows are readily available for all departments, leading to unrealistic expectations for real world criminal proceedings. The media often portrays digital experts as genuises who work best alone and can solve a case independently. In reality, digital forensics investigations involve a collaborative effort to develop a wide set of diverse skills.

An example of a self-forensic tool used for digital extraction is Evidence Center by Belkasoft (Lun, 2012). Evidence Center can be used by investigators with evidence extraction of “messenger history profile, allocated disk space, unallocated disk space, RAM, Pagefile and Hibernation file” (Lun, 2012). When using this program, investigators are able to store all extracted evidence from the instant messenger into a database, which can be used to further analyze the data (Lun, 2012). However, this program isn’t successful in retrieving every type of information, such as pictures or videos (Lun, 2012). As a result, investigators would need to use an additional program while tracing the instant message

N. L. Beebe & J. G. Clark [73] designed a new model which was based on the principles decided at the starting of the investigation .According to this framework the investigation phases can be divided in hierarchical order. Figure 10: A Hierarchical, Objective-Based Framework for the Digital Investigation Process (HODIP) 4.13.2 Phases of HODIP All the phases listed in the framework has already been described in the above mentioned frameworks . 4.14 Computer Forensic Field Triage Process Model (CFFTPM) 4.14.1 Introduction M. K. Rogers, J. Goldman, R. Mislan, T. Wedge & S. Debrota [74] recommends an onsite approach to provide the identification, analysis and interpretation of digital evidence within a short time span without the urge to return the devices or media back to the lab. It also does not require taking the complete

Dress codes targeted at females have become too strict and unrealistic. Between the developmental stages, and clothing stores with the items/styles they sell, there is not much females can do about it. Plus, they’re always being compared to the kids in younger grades even though younger kids are much less mature. Why is that? A big part of why female dress codes have become unrealistic is that they are developing more, and that means that certain things will look better than others, or certain things may be “more acceptable” than others.

The main focus of this project was to provide a means of education to digital forensic investigations to develop better and efficient tools to overcome the anti forensic packages. The future of this project could be extended to implement many other anti forensic techniques and features like encryption, steganography and even targeting computer forensic tool vulnerabilities. It would be a disaster if all these techniques are combined and implemented. The future developments could also make use of other digital forensic tools like Prodiscover, Encase and also new computer forensic tools being developed currently in the industry. Defeating cross view rootkit detection tools in a generic

The following section will consider advantages and limitation of the first two mentioned types of digital forensics: Traditional (dead) and Live computer forensics. TRADITIONAL (DEAD) VS LIVE DIGITAL FORENSICS Traditional (Dead) Forensics In order forensic acquisition to be more reliable it must be performed on computers that have been powered off. This type of forensics is known as ‘traditional’ or 'dead ' forensic acquisition. The whole process of dead acquisition, including search and seizure flowchart and acquisition of digital evidence flowchart is shown on Figure 2 and Figure 3 respectively.
