Retired municipal file servers still sit online with old shares after their replacements go live. Which mitigation best reduces lingering exposure?
Select an answer to reveal the explanation.
Short Explanation
Old servers that nobody owns are abandoned houses with the lights on. Decommission properly—sanitize data, pull them off the network—so yesterday's file share does not become tomorrow's breach.
Full Explanation
Secure decommissioning removes systems from service, sanitizes or destroys sensitive data as required, and eliminates unmanaged network exposure. Leaving orphaned servers online, publishing obsolete shares, or recycling weak defaults prolongs attack surface after migration is complete.
