Vulnerability discussion

Information protection needs are technology-independent, required capabilities to counter threats to organizations, individuals, or the Nation through the compromise of information (i.e., loss of confidentiality, integrity, or availability). Information protection needs are derived from the mission/business needs defined by the organization, the mission/business processes selected to meet the stated needs, and the organizational risk management strategy. Information protection needs determine the required security controls for the organization and the associated information systems supporting the mission/business processes.Inherent in defining an organizations information protection needs is an understanding of the level of adverse impact that could result if a compromise of information occurs. The security categorization process is used to make such potential impact determinations. Mission/business process definitions and associated information protection requirements are documented by the organization in accordance with organizational policy and procedure.One of the primary missions of Voice Video systems is the DISN Voice Precedence for mission-critical decision-maker communications, especially during times of crisis. A primary business function includes FES processes. These, along with other mission/business functions, must be documented in the System Security Plan (SSP).

Review the organizational Voice Video SSP for the primary voice communication system. Verify that the configuration provides the originating telephone number of an FES call to the PSAP through a transfer of ANI or PS/ALI information. If the originating telephone number of an FES call is not available, or is not provided to the PSAP, this is a finding.

Fix text

Document and implement the organizational Voice Video system to support FES at all locations. Configure the primary voice communication system to provide the originating telephone number of an FES call to the PSAP through a transfer of ANI or PS/ALI information.
