What is DNS cache locking, and what does it prevent?
What will be an ideal response?
DNS cache locking is a DNS security feature that allows you to control whether data in the DNS cache can be overwritten. An attacker can falsify update information, causing cached data to be overwritten by the attacker's data, resulting in cache poisoning. Cache locking prevents any updates to a cached record until the TTL expires.
