Investigators retrieve information from a computer or its component parts. The information you retrieve might already be on the drive, but it might not be easy to find or decipher. In contrast, network forensics yields information about how a perpetrator or an attacker gained access to a network. Network forensics investigators use log files to determine when users logged on and determine which URLs users accessed, how they logged on to the network, and from what location. Keep in mind, however,.
Of the latest technical improvements and trends in computer investigations. Also, keep up to date with the most recent books and read as much as possible about computer investigations and forensics. As a computer investigation and forensics professional, you’re expected to maintain honesty and integrity. You must conduct yourself with the highest levels of integrity in all aspects of your life. Any indiscreet actions can embarrass you and give opposing attorneys opportunities to discredit you.
Link has changed because of site updates, use the search feature. In your preliminary assessment, you assume that the hard disk and storage media include intact files, such as e-mail messages, deleted files, and hidden files. A range of software is available for use in your investigation; your office uses the tool Technology Pathways ProDiscover. This chapter introduces you to the principles applied to computer forensics. In Chapter 7, you learn the strengths and weaknesses of several software.
So be mindful of what you write or e-mail, even to a fellow investigator. Often these journals start out as handwritten notes, but you can transcribe them to electronic format periodically. Basic report writing involves answering the six Ws: who, what, when, where, why, and how. In addition to these basic facts, you must also explain computer and network processes. Typically, your reader is a senior personnel manager, a lawyer, or occasionally a judge who might have little computer knowledge.
Controllers that connect to high-end servers or mainframes. These systems provide redundancy and high-speed data access and can make many small disks appear as one very large drive. Other variations of RAID besides 0, 1, and 5 are specific to their vendor or application. RAID 0 provides rapid access and increased data storage (see Figure 4-11). In RAID 0, two or more disk drives become one large volume, so the computer views the disks as a single disk. The tracks of data on this mode of storage.
