SRG-APP-000065-NDM-000214
Group -
The HYCU VM console must be configured to enforce the limit of three consecutive invalid logon attempts, after which time it must block any logon attempt for 15 minutes.
By limiting the number of failed logon attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced.Rule Medium Severity -
SRG-APP-000068-NDM-000215
Group -
The HYCU VM console must display the Standard Mandatory DoD Notice and Consent Banner before granting access to the device.

SRG-APP-000069-NDM-000216
Group -
The HYCU VM console must retain the Standard Mandatory DoD Notice and Consent Banner on the screen until the administrator acknowledges the usage conditions and takes explicit actions to log on for further access.
The banner must be acknowledged by the administrator prior to the device allowing the administrator access to the network device. This provides assurance that the administrator has seen the message...Rule Medium Severity -
SRG-APP-000516-NDM-000317
Group -
The HYCU VM/server must be configured to disable SSH.
It is detrimental for applications to provide functionality exceeding requirements or mission objectives. These unnecessary capabilities or services are often overlooked and therefore may remain un...Rule Medium Severity -
SRG-APP-000080-NDM-000220
Group -
The HYCU VM console and HYCU Web UI must be configured to use an authentication server for authenticating users prior to granting access to protect against an individual (or process acting on behalf of an individual) falsely denying having performed organization-defined requirements.
Centralized management of authentication settings increases the security of remote and nonlocal access methods. This control is a particularly important protection against the insider threat. This ...Rule High Severity -

Group -
The HYCU server must generate audit records when successful/unsuccessful attempts to modify or delete administrator privileges occur.

SRG-APP-000096-NDM-000226
Group -
The HYCU server must produce audit records containing information to establish when events occurred, where events occurred, the source of the event, the outcome of the event, and identity of any individual or process associated with the event.
It is essential for security personnel to know what is being done, what was attempted, where it was done, when it was done, and by whom it was done in order to compile an accurate risk assessment. ...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.
