Canal bylaws require lock-camera footage to remain unaltered and undeleted for seven years. Which storage protection should the security engineer configure?
Select an answer to reveal the explanation.
Short Explanation
Seven years means a real WORM padlock on the footage—time-based immutability. Soft delete isn’t a seven-year seal, and once that policy is locked you can’t shave the calendar.
Full Explanation
Time-based retention policies on immutable storage enforce write-once read-many protection for a known interval such as seven years at container or version scope. A locked policy cannot be shortened or removed until the retention expires. Soft delete and versioning aid recovery but do not provide the same WORM guarantee. Legal hold is appropriate when retention is event-driven rather than a fixed bylaw period; this scenario calls for time-based immutability.
