# 8 Security Considerations

The metadata and ancillary streams usually contain Personally Identifiable Information (PII). The video and audio streams might contain protected information. The underlying SMPTE protocols do not specify any security protections to ensure confidentiality, integrity, or availability of the various data streams. DICOM does not specify any additions to the SMPTE protocols to provide such protection. Authorization and authentication of access to the DICOM-RTV Service is handled by configuration. Authentication is not re-confirmed at initiation of the underlying SMPTE protocols, and DICOM does not specify any additions to the SMPTE protocols for access control, authorization, or authentication.

The potential eavesdropping, replay, message insertion, deletion, modification, man-in-the-middle and denial of service attacks have not been analyzed. That analysis is up to the individual sites and installations.

Individual sites and installations will also need to perform their own assessments and selection of security mechanisms and add protections as necessary. The data rates and strict timing requirements for the data streams require careful analysis of any security mechanisms that are added. There do exist security mechanisms that operate at and below the IP level that can meet foreseen use cases, but there is insufficient experience or evidence to justify DICOM making a recommendation.
