Explanation

The most important rule for digital investigations is to ensure that the original data is never modified. Digital investigations are the processes of collecting, preserving, analyzing, and presenting digital evidence from various sources, such as computers, mobile devices, networks, or cloud services. Digital evidence is any data that can support or refute a hypothesis or claim related to a criminal or civil case. Digital evidence is often fragile, volatile, and easily altered or destroyed, either intentionally or unintentionally. Therefore, it is crucial to ensure that the original data is never modified during the digital investigation, to maintain its integrity and authenticity, and to avoid compromising its validity and admissibility in court. To ensure that the original data is never modified, the following steps should be followed: Use write blockers or read-only mode to prevent any changes to the data source. Make a bit-by-bit copy or image of the data source and verify its accuracy using hashing or checksum techniques. Store the original data source and the copy or image in a secure and tamper-evident location or Perform the analysis and examination on the copy or image, not on the original data source. Document and justify any changes or modifications made to the copy or image during the analysis and examination.
