Undetected, these changes can alter the meaning and value of critical evidence. By implementing a few simple steps, you can ensure that everyone is working from the exact same set of facts, and be able to prove if a file was altered prior to arriving into your care.

Skip to main content. Start your free trial. Book description Essential reading for launching a career in computer forensics Internet crime is on the rise, catapulting the need for computer forensics specialists. Include all the information you need to and nothing more. Start with a simple outline. You don't have to produce the final product in one sitting.
You might be far more productive when you get something into an outline, and then go back over the material to edit it. Getting a memory dump into an outline makes sure you don't overlook crucial ideas while wrestling with the details.
After you have an outline and a general flow, you need to consider how to organize the presentation. Although each presentation is different, you can use a few common rules of thumb. First, use a presentation method you are comfortable with. If you are most comfortable drawing pictures as you go, set up a white board and dispense with the PowerPoint presentation. If you do use PowerPoint, plan for about 30 slides each hour. This guideline works well for general presentations.
If you feel you need to spend more time on one topic, consider creating multiple slides for that topic. If you spend too much time on a single slide, it can become stale, and you risk losing your audience's attention.
Use what works best for your personality. Remember that the main purpose for your presentation is to present evidence you believe proves one or more facts in a case. Take the audience on a tour through the evidence trail that leads them to a conclusion as to what happened that resulted in this case. Sometimes the presentation should take a chronological approach. At other times, a topical approach keeps consistency and cohesion. Don't get locked in to a particular type of presentation organization.
Think through what you want your audience to take away from your presentation. Use the flow and organization that makes sense to you and that leads the audience where you want them to go. The outline approach works best for us. Whether we are writing a report or developing a presentation, we always work from an outline.
As the outline grows and matures, we expand the content into the final format. For presentations, we frequently use PowerPoint. We generally move from an outline to PowerPoint only when we have each slide listed and the major points for each slide. Experiment and find a method that works well for your style. Above all else, use the KISS method when presenting technical information to others even other technical people. Part of the challenge in any presentation of evidence is to make the complex seem simple.
Always use the simplest techniques you can think of to present evidence. Whenever possible, use visual aids. The common saying, 'a picture is worth a thousand words,' is truer today than ever. Humans process visual images far more efficiently than written words. Whenever you can use a picture, drawing, or chart to convey a concept with just few words, use it. The audience will remember a picture far longer than any words you use to describe it.
We also discuss a few investigation processes regarding data collection from nonvolatile memory storage. Data moves so easily and freely between computers and devices, especially today with the inexpensive price of storage devices like flash drives and external Universal Serial Bus USB storage.
Not only may data exist on a machine or in the cloud, but on many removable devices as well. It is tough for the average person to keep track of all this data. It is even more important for the forensic investigator to understand the role and value Link LNK files and USB devices have as evidence.
This data can be helpful when trying to determine if sensitive data has been removed from a facility or if data relevant to a case is present on removable media that might need to be obtained my attorneys.
Sometimes it is easier to detect infected hosts in the networks if we analyze the network traffic than using an Antivirus running on the host. However, like every good thing, it can be abused by spammers and hackers, and infect is.
Network forensics is a comparatively new field of forensic science. Depending upon the type of case, network forensics can add value to computer forensics cases and help identify digital devices operating on the network. A much bigger concern, they say, should be the security holes that will open up in many business organizations as the world moves over to internet protocol version six IPv6.
In this article we are going to discuss and execute the techniques and methodologies which can make the future of internet …. The job consisted of the digital examinations of computers and cell phones as well as many other digital devices.
On the law enforcement side your thought process is to get the data off of the device and present it to the prosecuting attorneys or the detective assigned to the case, using whatever tools you have at your disposal. Such popularity has made it one of the most targeted operating systems by malicious attackers. As a result, it is often used as a platform to access personal and work place data , or even to commit policy breaches assisting in the commission of criminal acts.
Investigations that are based on electronic evidence stand a very high chance of being carried out on a system with one or the other version of Windows operating system.
