The Infoblox DNS server must implement cryptographic mechanisms to detect changes to information during transmission unless otherwise protected by alternative physical safeguards, such as, at a minimum, a Protected Distribution System (PDS).

Description
Encrypting information for transmission protects it from unauthorized disclosure and modification. Cryptographic mechanisms implemented to protect information integrity include, for example, cryptographic hash functions that have common application in digital signatures, checksums, and message authentication codes. Confidentiality is not an objective of DNS, but integrity is. DNSSEC digitally signs DNS information to authenticate its source and ensure its integrity.
