Description
When network elements do not dynamically reconfigure the data security attributes as data is created and combined, the possibility exist that security attributes will not correctly reflect the data with which they are associated. For the Enterprise Voice, Video, and Messaging Session Manager, the use of 802.1q tags on media and signaling, and the use of VLANs provides this layer of security. VLANs facilitate access and traffic control for voice video system components and enhanced QoS. 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.

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-260044r1117223_chk)

Verify the Enterprise Voice, Video, and Messaging Session Manager uses a voice or video VLAN separate from all other VLANs. If the Enterprise Voice, Video, and Messaging Session Manager uses a voice or video VLAN that is not separate from all other VLANs, this is a finding.
