SSCP Incident Response and Recovery Practice Question
What is the primary purpose of establishing a chain of custody for digital evidence?
⚠ Common exam trap
Watch out — candidates often confuse chain of custody with data preservation techniques like encryption or compression, but the exam specifically tests that its core purpose is to ensure integrity and provide an unbroken audit trail of handling, not to secure or reduce the data.

Correct answer & explanation
✓
To maintain evidence integrity and track handling
The primary purpose of establishing a chain of custody for digital evidence is to maintain evidence integrity and track every person who handled the evidence from collection through presentation in court. This process ensures that the evidence has not been tampered with, altered, or corrupted, which is critical for admissibility under legal standards such as the Federal Rules of Evidence (FRE) Rule 901. By documenting each transfer with timestamps, signatures, and hash values (e.g., MD5 or SHA-256), the chain of custody provides a verifiable audit trail that supports the evidence's authenticity and reliability.
