Title

The DNS server implementation must maintain the integrity of information during reception. (Cat II impact)

Discussion

Information can be either unintentionally or maliciously disclosed or modified during reception, including, for example, during aggregation, at protocol transformation points, and during packing/unpacking. These unauthorized disclosures or modifications compromise the confidentiality or integrity of the information. Confidentiality is not an objective of DNS, but integrity is. DNS is responsible for maintaining the integrity of DNS information while it is being received.

Check Content

Review the DNS server implementation configuration to determine if the DNS server maintains the integrity of information during reception. If the DNS server does not maintain integrity during reception, this is a finding.
