The ESXi host must protect the confidentiality and integrity of transmitted information by isolating IP-based storage traffic.

Description
Virtual machines (VMs) might share virtual switches and VLANs with the IP-based storage configurations. IP-based storage includes vSAN, iSCSI, and NFS. This configuration might expose IP-based storage traffic to unauthorized VM users. IP-based storage frequently is not encrypted. It can be viewed by anyone with access to this network. To restrict unauthorized users from viewing the IP-based storage traffic, the IP-based storage network must be logically separated from any other traffic. Configuring the IP-based storage adaptors on separate VLANs or network segments from other VMkernels and VMs will limit unauthorized users from viewing the traffic.

Who does this work

8 NICE work roles and 7 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-256413r958908_chk)

If IP-based storage is not used, this is not applicable. From the vSphere Client, select the ESXi host and go to Configure >> Networking >> VMkernel adapters. Select each IP-based storage VMkernel adapter and view the enabled services. If any services are enabled on an NFS or iSCSI IP-based storage VMkernel adapter, this is a finding. If any services are enabled on a vSAN VMkernel adapter other than vSAN, this is a finding. From the vSphere Client, select the ESXi host and go to Configure >> Networking >> VMkernel adapters. Review the VLANs associated with any IP-based storage VMkernels and verify they are dedicated for that purpose and are logically separated from other functions. If any IP-based storage networks are not isolated from other traffic types, this is a finding.

Fix Text (F-60031r886019_fix)

Configuration of an IP-based VMkernel will be unique to each environment. From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> Networking >> VMkernel adapters. Select the VMkernel used for IP-based storage and click "Edit...". On the "Port" properties tab, uncheck all services. Click "OK". Note: For VMkernels used for vSAN, leave the vSAN service enabled and uncheck all others. From the vSphere Client, go to Hosts and Clusters >> select the ESXi Host >> Configure >> Networking >> Virtual switches. Find the port group that is dedicated to IP-based storage and click the "..." button next to the name. Click "Edit Settings". On the "Properties" tab, change the "VLAN ID" to one dedicated for IP-based storage traffic. Click "OK".
