VCWN-06-000051 - The system must protect the confidentiality and integrity of transmitted info by isolating IP-based storage traffic.


Virtual machines 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 virtual machine 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 the production traffic. Configuring the IP-based storage adaptors on separate VLANs or network segments from other VMkernels and Virtual Machines will limit unauthorized users from viewing the traffic.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.


Configuration of an IP-Based VMkernel will be unique to each environment but for example to modify the IP address and VLAN information to the correct network on a standard switch for an iSCSI VMkernel do the following:

From the vSphere Client select the ESXi host and go to Configuration > Networking > On the vSwitch that contains the iSCSI VMkernel select Properties. Select the iSCSI VMkernel and click Edit > On the General tab uncheck everything and set the appropriate VLAN ID > Go to the IP Settings tab > Enter the appropriate IP address and subnet information and click OK.
