What should be performed to securely store a duplicate copy of a CEO's hard drive for forensic processes?

Using a write blocker and the dd command in a live Linux environment is a critical process in securely creating a duplicate copy of a hard drive, especially for forensic purposes. A write blocker ensures that no modifications are made to the original data during the imaging process, which is vital for maintaining the integrity and authenticity of the evidence. This tool prevents any data from being accidentally overwritten or altered when the hard drive is being accessed.

The dd command is a powerful utility in Linux that allows for a bit-by-bit copy of the hard drive, ensuring that every piece of data, including hidden files, unused space, and deleted files, is preserved in the duplicate. This comprehensive copying is crucial for forensic investigations where even the smallest detail might be pertinent to the case.

By creating a copy of the CEO's hard drive in a manner that protects the integrity of the original data, the forensic team can ensure that the duplicate can be analyzed without compromising the chain of custody or the validity of the evidence. This method aligns with best practices in digital forensics, making it the most appropriate choice among the provided options.
