Discussion

Information can be either unintentionally or maliciously disclosed or modified during preparation for transmission, 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 prepared for transmission.

Check Content
