These protocols are generally considered to be vulnerable due to their simplicity and lack of any security features. NOTE: Many of these configuration files are transferred using protocols such as BootP or TFTP which are designated “local management” per the DoD PPSM VAs for these protocols. (This is applicable to PC applications only) NOTE: To satisfy the encryption requirement here, the file can be encrypted directly (preferred) or downloaded over an encrypted channel. As noted earlier, digital signatures and the file integrity must also be validated before the configuration file is used. While encryption will also protect binary files, the threat is less due to the inability to easily read the information in the file without a program designed to interpret the binary code.

Encryption of this file is also required if the file contains the password used to access the endpoint’s configuration information and settings menus. This can prevent man-in-the-middle attacks. The best method for maintaining the confidentiality of human readable files is to require that they be directly encrypted or downloaded over an encrypted channel. This facilitates man-in-the-middle attacks. Additionally, the file is easier to understand and therefore makes it easier to modify it and then forward it to its destination. If the file is human readable, intelligence can be gathered by capturing the file while it is in transit.

However, there is the potential that such files may be human readable as is XML code and most VVoIP signaling protocols. Many vendors use configuration files of this sort that are a compact binary format that is only interpretable by the endpoint’s firmware or PD application. The confidentiality of these files is critical to preventing compromise of the PC application, hardware endpoint, and the system itself. Many PC based communications applications are fully configured locally on the platform, however, in some cases they rely on a configuration file downloaded from the system with which they are associated. These configuration settings can be updated occasionally or regularly by resetting and re-registering the endpoint, which causes an updated configuration file to be downloaded. In any case, no matter how much of the OS is stored as firmware, each endpoint requires a customized configuration settings file to be downloaded that individualizes the endpoint to meet the needs of the user to which it is assigned. The more of the OS that is stored the device, the quicker it initializes.

To varying degrees some, most, or all of the endpoint’s OS can be stored on the device as firmware. The code necessary to download this OS is stored in ROM or Flash Memory and is called firmware. NOTE: Hardware based VVoIP endpoints are like diskless computers on the LAN which need to download an operating system and configurations before they can operate.

This file contains the phone number assigned to the endpoint the IP addresses (or URLs) of the LSC(s) with which the endpoint is associated the software menus specific to the system the user’s personal preferences and speed dial numbers as well as other information critical to the operation of the endpoint.

During VVoIP endpoint registration with the LSC, a file is downloaded by the endpoint from the LSC that contains specific configuration parameters needed by the endpoint to operate as needed to support its assigned user.
