ISC2 Systems Security Certified Practitioner (SSCP) Practice Question
Your organization moves daily transaction logs over a leased line to a disaster-recovery site. Security policy requires the offsite copy to be provably identical to the original so accountants can rely on it during an outage. Which control most directly maintains data accuracy and detects silent corruption during and after transfer?
Compute a cryptographic hash for each log file and verify the digest after reception.
Synchronize both servers with an authenticated NTP source before sending the files.
Enable TLS on the leased line without additional post-transfer validation.
Store the logs on RAID-1 arrays at both sites to protect against disk failure.
Generating a cryptographic hash such as SHA-256 on the source system and recomputing it at the destination provides an unambiguous integrity check. If any bit in the file changes, the resulting digest will differ, immediately revealing corruption or tampering. Transport-layer encryption like TLS protects data in motion but does not confirm that the stored copy is still accurate. RAID-1 keeps disks available but blindly mirrors any corrupted block that reaches the array. Time synchronization improves the reliability of timestamps but offers no protection for the data itself. Therefore, hashing and comparing digests is the most appropriate integrity control for ensuring data accuracy and reliability.
