Title

The web server must maintain the confidentiality and integrity of information during preparation for transmission. (Cat II impact)

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. An example of this would be an SMTP queue. This queue may be added to a web server through an SMTP module to enhance error reporting or to allow developers to add SMTP functionality to their applications. Any modules used by the web server that queue data before transmission must maintain the confidentiality and integrity of the information before the data is transmitted.

Check Content

Review the web server documentation and deployed configuration to determine if the web server maintains the confidentiality and integrity of information during preparation before transmission. If the confidentiality and integrity are not maintained, this is a finding.

Fix Text

Configure the web server to maintain the confidentiality and integrity of information during preparation for transmission.
