-
The vCenter Server must enforce a 90-day maximum password lifetime restriction.
Any password, no matter how complex, can eventually be cracked. Therefore, passwords must be changed at specific intervals. One method of minimizing this risk is to use complex passwords and perio...Rule Medium Severity -

The vCenter Server must terminate vSphere Client sessions after 15 minutes of inactivity.
Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port th...Rule Medium Severity -

Group -
The vCenter Server user roles must be verified.
Users and service accounts must only be assigned privileges they require. Least privilege requires that these privileges must only be assigned if needed to reduce risk of confidentiality, availabil...Rule Medium Severity -
SRG-APP-000247
Group -
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).
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 exc...Rule Medium Severity -
SRG-APP-000291
Group -
The vCenter Server must provide an immediate real-time alert to the system administrator (SA) and information system security officer (ISSO), at a minimum, on every Single Sign-On (SSO) account action.
Once an attacker establishes initial access to a system, they often attempt to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to create a new ac...Rule Medium Severity -
SRG-APP-000345
Group -
The vCenter Server must set the interval for counting failed login attempts to at least 15 minutes.
By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute forcing, is reduced. Limits are imposed by locking the a...Rule Medium Severity -
SRG-APP-000358
Group -
The vCenter Server must be configured to send logs to a central log server.
vCenter must be configured to send near real-time log data to syslog collectors so information will be available to investigators in the case of a security incident or to assist in troubleshooting.Rule Medium Severity -
SRG-APP-000360
Group -
The vCenter server must provide an immediate real-time alert to the system administrator (SA) and information system security officer (ISSO), at a minimum, of all audit failure events requiring real-time alerts.
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impe...Rule Medium Severity -
SRG-APP-000371
Group -
The vCenter Server must compare internal information system clocks at least every 24 hours with an authoritative time server.
Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when condu...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.
