An incident handler needs to preserve a hard drive from a compromised system. Which two actions are essential to maintain the integrity of the evidence?
Trap 1: Store the original drive in a Faraday bag
Faraday bags prevent wireless communication but are not essential for integrity.
Trap 2: Copy files directly to an external drive using the operating system
Direct copying may alter metadata and is not forensically sound.
Trap 3: Boot the system from the hard drive to collect volatile data
Booting the system modifies the drive, compromising integrity.
- A
Store the original drive in a Faraday bag
Why wrong: Faraday bags prevent wireless communication but are not essential for integrity.
- B
Copy files directly to an external drive using the operating system
Why wrong: Direct copying may alter metadata and is not forensically sound.
- C
Use a write blocker when creating the forensic image
Write blocker ensures no data is written to the source drive.
- D
Compute a cryptographic hash of the original drive before imaging
Hashing creates a baseline to verify the image matches the original.
- E
Boot the system from the hard drive to collect volatile data
Why wrong: Booting the system modifies the drive, compromising integrity.
