SRG-APP-000516
Group -
The vCenter Server must use unique service accounts when applications connect to vCenter.
To not violate nonrepudiation (i.e., deny the authenticity of who is connecting to vCenter), when applications need to connect to vCenter they must use unique service accounts.Rule Medium Severity -
SRG-APP-000516
Group -
The vCenter Server must protect the confidentiality and integrity of transmitted information by isolating Internet Protocol (IP)-based storage traffic.
Virtual machines might share virtual switches and virtual local area networks (VLAN) with the IP-based storage configurations. IP-based storage includes vSAN, Internet Small Computer System Interf...Rule Medium Severity -
SRG-APP-000358
Group -
The vCenter server must be configured to send events to a central log server.
vCenter server generates volumes of security-relevant application-level events. Examples include logins, system reconfigurations, system degradation warnings, and more. To ensure these events are a...Rule Medium Severity -
SRG-APP-000516
Group -
The vCenter Server must disable or restrict the connectivity between vSAN Health Check and public Hardware Compatibility List (HCL) by use of an external proxy server.
The vSAN Health Check is able to download the HCL from VMware to check compliance against the underlying vSAN Cluster hosts. To ensure the vCenter server is not directly downloading content from th...Rule Medium Severity -
SRG-APP-000516
Group -
The vCenter Server must configure the vSAN Datastore name to a unique name.
A vSAN Datastore name by default is "vsanDatastore". If more than one vSAN cluster is present in vCenter, both datastores will have the same name by default, potentially leading to confusion and ma...Rule Medium Severity -
SRG-APP-000516
Group -
The vCenter Server must disable Username/Password and Windows Integrated Authentication.
All forms of authentication other than Common Access Card (CAC) must be disabled. Password authentication can be temporarily reenabled for emergency access to the local Single Sign-On (SSO) account...Rule Medium Severity -
SRG-APP-000516
Group -
The vCenter Server must restrict access to the default roles with cryptographic permissions.
In vSphere, the built-in "Administrator" role contains permission to perform cryptographic operations such as Key Management Server (KMS) functions and encrypting and decrypting virtual machine dis...Rule Medium Severity -
SRG-APP-000516
Group -
The vCenter Server must restrict access to cryptographic permissions.
These permissions must be reserved for cryptographic administrators where virtual machine encryption and/or vSAN encryption is in use. Catastrophic data loss can result from poorly administered cry...Rule Medium Severity -
SRG-APP-000516
Group -
The vCenter Server must have Mutual Challenge Handshake Authentication Protocol (CHAP) configured for vSAN Internet Small Computer System Interface (iSCSI) targets.
When enabled, vSphere performs bidirectional authentication of both the iSCSI target and host. When not authenticating both the iSCSI target and host, the potential exists for a man-in-the-middle a...Rule Medium Severity -
SRG-APP-000516
Group -
The vCenter Server must have new Key Encryption Keys (KEKs) reissued at regular intervals for vSAN encrypted datastore(s).
The KEK for a vSAN encrypted datastore is generated by the Key Management Server (KMS) and serves as a wrapper and lock around the Disk Encryption Key (DEK). The DEK is generated by the host and is...Rule Medium Severity

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
