A cybersecurity analyst has been called to a crime scene that contains several technology items including a computer. Which technique will be used so that the information found on the computer can be used in court?Torrootkitlog collectionunaltered disk imageNavigation Bar
Solution
The technique that a cybersecurity analyst would use so that the information found on the computer can be used in court is creating an "unaltered disk image".
Here are the steps:
-
First, the analyst would need to isolate and secure the computer system to ensure that it cannot be tampered with. This is to maintain the integrity of the evidence.
-
Next, the analyst would use a process called "disk imaging" to create an exact copy of the hard drive. This includes all files, operating system data, and free space. This is done to preserve the original state of the system and to allow for analysis without risking damage to the original evidence.
-
The disk image is then hashed, which is a process that creates a unique identifier for the data. This is done to ensure that the data remains unaltered during the analysis process. If the hash value changes, it means that the data has been altered.
-
The analyst can then use forensic tools to analyze the disk image, searching for evidence of the crime.
-
All steps of this process are carefully documented to maintain a chain of custody for the evidence. This documentation is crucial for the evidence to be admissible in court.
-
Finally, the analyst would prepare a report detailing their findings, which could then be used in court proceedings.
