Authorization procedures and controls must be implemented to ensure each authenticated entity also has a validated and current authorization. Authorization is the process of determining whether an entity, once authenticated, is permitted to access a specific asset. Registration authenticates and authorizes endpoints with the Voice Video Session Manager.
For most VoIP systems, registration is the process of centrally recording the user ID, endpoint MAC address, service/policy profile with 2 stage authentication prior to authorizing the establishment of the session and user service. The event of successful registration creates the session record immediately. VC systems register using a similar process with a gatekeeper. Without enforcing registration, an adversary could impersonate a legitimate device on the Voice Video network. </VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>DPMS Target Voice Video EndpointDISADPMS TargetVoice Video Endpoint2915SV-82475V-67985CCI-000213Configure the Voice Video Endpoint to register with a Voice Video Session Manager.Verify the Voice Video Endpoint registers with a Voice Video Session Manager.

Secure configuration management relies on performance and functional attributes of products to determine the appropriate security features and assurances used to measure a system configuration state. When configuration changes are made, it is critical for those changes to be implemented by the Voice Video Endpoint as quickly as possible. This ensures that Voice Video Endpoints communicate using the correct address books, session managers, gateways, and border elements.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>DPMS Target Voice Video EndpointDISADPMS TargetVoice Video Endpoint2915SV-81207V-66717CCI-000213Configure the Voice Video Endpoint to dynamically implement configuration file changes.Verify the Voice Video Endpoint dynamically implements configuration file changes.

System use notifications are required only for access via logon interfaces with human users and are not required when such human interfaces do not exist. This requirement applies to Voice Video Endpoints that have the concept of a user account and have the logon function residing on the network element.
The banner must be formatted in accordance with current policy. Use the following verbiage for network elements that can accommodate banners of 1300 characters:
"You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only.
By using this IS (which includes any device attached to this IS), you consent to the following conditions:
-The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations.
-At any time, the USG may inspect and seize data stored on this IS.
-Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG-authorized purpose.
-This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy.
-Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details."
Use the following verbiage for operating systems that have severe limitations on the number of characters that can be displayed in the banner:

The demonstration of the vulnerability also exists on www.securityfocus.com under Bugtraq ID: 25987, which pops up a specific alert box on the user’s workstation after downloading a SIP invite.
While this vulnerability has been demonstrated on a specific IP phone, it could potentially affect all SIP-based endpoints or clients and their signaling partners. This vulnerability is a result of improper filtering or validation of the content of the various fields in the SIP invite and potentially the Session Description Protocol (SDP) portion of the invite. The injected code potentially causes malicious code to be run on the target device, to include an endpoint (hard or soft), a session controller, or any other SIP signaling partner.

A trust anchor is an authoritative entity represented via a public key. Within a chain of trust, the top entity to be trusted is the "root certificate" or "trust anchors" such as a Certification Authority (CA). A certification path starts with the subject certificate and proceeds through a number of intermediate certificates up to a trusted root certificate, typically issued by a trusted CA.
This requirement verifies that a certification path to an accepted trust anchor is used for certificate validation and that the path includes status information. Path validation is necessary for a relying party to make an informed trust decision when presented with any certificate not already explicitly trusted. Status information for certification paths includes certificate revocation lists or online certificate status protocol responses.

A Voice Video Endpoint with a PC port may break 802.1x LAN access control mechanisms when the network access switchport is authorized during the Voice Video Endpoint authentication to the network. This condition may permit devices connected to the PC port to access the LAN. The access switchport can be configured in one of the following modes: single-host, multi-host, or multi-domain. Single-host allows only one device to authenticate, and only packets from this devices MAC address will be allowed, dropping all other packets. Multi-host mode requires one host to authenticate but once this is done, all packets regardless of source MAC address will be allowed. For both the PC attached to the PC port and the Voice Video Endpoint to authenticate separately, multi-domain authentication on the access switchport must be configured. This divides the switchport into a data and a voice domain. In this case if more than one device attempts authorization on either the voice or the data domain of a port, the switchport goes into an error disable state. Disabling the PC port requires the network access switchports are configured with the appropriate VLAN for the VVoIP or VTC traffic and placing the disabled PC port traffic on the unused VLAN.

Voice Video Endpoints may transmit classified conversations over unclassified networks. Voice Video Endpoint microphones, speakers, and supporting electronics may pick up conversation audio within the area and conduct it over the network connection, even when the endpoint is on-hook, powered or not. The Technical Surveillance Counter-Measures (TSCM) program protects sensitive government information, to include classified information, through the establishment of on-hook audio security standards. Voice Video Endpoints certified by NTSWG are modified to prevent this behavior, or limit it to within acceptable levels.

VLAN tags are used as security attributes. These attributes are typically associated with signaling and media streams within the application and are used to enable the implementation of access control and flow control policies. Security labels for packets may include traffic flow information (e.g., source, destination, protocol combination), traffic classification based on QoS markings for preferred treatment, and VLAN identification.
Virtualized networking is used to separate voice video traffic from other types of traffic, such as data, management, and other special types. VLANs provide segmentation at layer 2. Virtual Routing and Forwarding (VRF) provides segmentation at layer 3, and works with Multiprotocol Label Switching (MPLS) for enterprise and WAN environments. When VRF is used without MPLS, it is referred to as VRF lite. For Voice Video systems, subnets, VLANs, and VRFs are used to separate media and signaling streams from all other traffic.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>DPMS Target Voice Video EndpointDISADPMS TargetVoice Video Endpoint2915SV-81191V-66701CCI-000366CCI-002272Configure the hardware Voice Video Endpoint to apply 802.1Q VLAN tags to signaling and media traffic.If the Voice Video Endpoint is not a hardware endpoint, this check procedure is Not Applicable.
