The vCenter Server passwords must contain at least one numeric character.
Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resistin...Rule Medium Severity -
The vCenter Server passwords must contain at least one special character.
Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resistin...Rule Medium Severity -
The vCenter Server must enable revocation checking for certificate-based authentication.
The system must establish the validity of the user-supplied identity certificate using Online Certificate Status Protocol (OCSP) and/or Certificate Revocation List (CRL) revocation checking. Satis...Rule Medium Severity -
The vCenter Server Machine Secure Sockets Layer (SSL) certificate must be issued by a DOD certificate authority.
Untrusted certificate authorities (CA) can issue certificates, but they may be issued by organizations or individuals that seek to compromise DOD systems or by organizations with insufficient secur...Rule Medium Severity -
The vCenter Server must enable data at rest encryption for vSAN.
Applications handling data requiring "data at rest" protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest. Data encryption...Rule Medium Severity -
The vCenter server must enforce SNMPv3 security features where SNMP is required.
SNMPv3 supports commercial-grade security, including authentication, authorization, access control, and privacy. Previous versions of the protocol contained well-known security weaknesses that were...Rule Medium Severity -
The vCenter Server must set the distributed port group Forged Transmits policy to "Reject".
If the virtual machine operating system changes the Media Access Control (MAC) address, the operating system can send frames with an impersonated source MAC address at any time. This allows an oper...Rule Medium Severity -
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 -
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 -
The vCenter server configuration must be backed up on a regular basis.
vCenter server is the control plane for the vSphere infrastructure and all the workloads it hosts. As such, vCenter is usually a highly critical system in its own right. Backups of vCenter can now ...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.
