Which of the following is a standard Unix command that would most likely be used to copy raw file system data for later forensic analysis?
Which of the following is a standard Unix command that would most likely be used to copy raw file system data for later forensic analysis?
The 'dd' command is a standard Unix utility that is commonly used to copy and convert raw file system data at a low level. It is particularly useful for forensic analysis because it can create exact bit-for-bit copies of storage devices, ensuring that no data is altered during the copying process. The other options, such as 'backup', 'cp', and 'gzip', are not suitable for creating raw disk images required for forensic purposes.
The correct answer is: A. dd The dd command is a standard Unix command that can be used to copy raw file system data. It is often used for forensic analysis because it can create a bit-for-bit copy of the data, without making any modifications. The other options are not as well-suited for forensic analysis: The backup command is typically used to back up files and directories, not raw file system data. The cp command can be used to copy files and directories, but it does not create a bit-for-bit copy of the data. The gzip command is used to compress files, not copy them.
dd, the disk/data duplicator (or, sometimes, disk destroyer) allows us to copy raw data from one source to another.
