Check: VCTR-67-000007
VMware vSphere 6.7 vCenter STIG:
VCTR-67-000007
(in versions v1 r4 through v1 r2)
Title
The vCenter Server must manage excess capacity, bandwidth, or other redundancy to limit the effects of information-flooding types of denial-of-service (DoS) attacks by enabling Network I/O Control (NIOC). (Cat II impact)
Discussion
DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity. Managing excess capacity ensures that sufficient capacity is available to counter flooding attacks. Employing increased capacity and service redundancy may reduce the susceptibility to some DoS attacks. Managing excess capacity may include, for example, establishing selected usage priorities, quotas, or partitioning.
Check Content
If distributed switches are not used, this is not applicable. From the vSphere Client, go to Networking >> select a distributed switch >> Configure >> Settings >> Properties. View the "Properties" pane and verify Network I/O Control is enabled. or From a PowerCLI command prompt while connected to the vCenter server, run the following command: Get-VDSwitch | select Name,@{N="NIOC Enabled";E={$_.ExtensionData.config.NetworkResourceManagementEnabled}} If Network I/O Control is disabled, this is a finding.
