Group -
vSphere UI must limit the amount of time that each Transmission Control Protocol (TCP) connection is kept alive.
Denial of service (DoS) is one threat against web servers. Many DoS attacks attempt to consume web server resources in such a way that no more resources are available to satisfy legitimate requests...Rule Medium Severity -

Group -
vSphere UI must limit the number of concurrent connections permitted.
Resource exhaustion can occur when an unlimited number of concurrent requests are allowed on a website, facilitating a denial-of-service attack. Unless the number of requests is controlled, the web...Rule Medium Severity -

vSphere UI must record user access in a format that enables monitoring of remote access.
Remote access can be exploited by an attacker to compromise the server. By recording all remote access activities, it will be possible to determine the attacker's location, intent, and degree of su...Rule Medium Severity -
SRG-APP-000089-WSR-000047

vSphere UI must generate log records for system startup and shutdown.
Logging must be started as soon as possible when a service starts and when a service is stopped. Many forms of suspicious actions can be detected by analyzing logs for unexpected service starts and...Rule Medium Severity -

vSphere UI plugins must be authorized before use.
The vSphere UI ships with a number of plugins out of the box. Any additional plugins may affect the availability and integrity of the system and must be approved and documented by the information s...Rule Medium Severity -

vSphere UI must be configured to limit access to internal packages.
The "package.access" entry in the "catalina.properties" file implements access control at the package level. When properly configured, a Security Exception will be reported if an errant or maliciou...Rule Medium Severity -

vSphere UI must have mappings set for Java servlet pages.
Resource mapping is the process of tying a particular file type to a process in the web server that can serve that type of file to a requesting client and identify which file types are not to be de...Rule Medium Severity -

vSphere UI must be configured with memory leak protection.
The Java Runtime environment can cause a memory leak or lock files under certain conditions. Without memory leak protection, vSphere UI can continue to consume system resources, which will lead to ...Rule Medium Severity -
SRG-APP-000141-WSR-000087
Group -
vSphere UI must not have any symbolic links in the web content directory tree.
A web server is designed to deliver content and execute scripts or applications on the request of a client or user. Containing user requests to files in the directory tree of the hosted web applica...Rule Medium Severity -
SRG-APP-000211-WSR-000030
Group -
The vSphere UI directory tree must have permissions in an out-of-the-box state.
As a rule, accounts on a web server are to be kept to a minimum. Only administrators, web managers, developers, auditors, and web authors require accounts on the machine hosting the web server. The...Rule Medium Severity -
SRG-APP-000223-WSR-000011

vSphere UI must restrict its cookie path.
Cookies are used to exchange data between the web server and the client. Cookies, such as a session cookie, may contain session information and user credentials used to maintain a persistent connec...Rule Medium Severity -

Group -
SRG-APP-000246-WSR-000149
Group -
vSphere UI must limit the number of allowed connections.
Limiting the number of established connections is a basic denial-of-service protection and a best practice. Servers where the limit is too high or unlimited can run out of system resources and nega...Rule Medium Severity -

vSphere UI must set the welcome-file node to a default web page.
Enumeration techniques, such as URL parameter manipulation, rely on being able to obtain information about the web server's directory structure by locating directories without default pages. In thi...Rule Medium Severity -

vSphere UI must be configured to show error pages with minimal information.
Web servers will often display error messages to client users with enough information to aid in the debugging of the error. The information given back in error messages may display the web server t...Rule Medium Severity -

vSphere UI must not enable support for TRACE requests.
"TRACE" is a technique for a user to request internal information about Tomcat. This is useful during product development but should not be enabled in production. Allowing an attacker to conduct a ...Rule Medium Severity -

vSphere UI must use a logging mechanism that is configured to allocate log record storage capacity large enough to accommodate the logging requirements of the web server.
To ensure the logging mechanism used by the web server has sufficient storage capacity in which to write the logs, the logging mechanism must be able to allocate log record storage capacity. vSpher...Rule Medium Severity -

vSphere UI must disable the shutdown port.
An attacker has at least two reasons to stop a web server. The first is to cause a denial of service, and the second is to put in place changes the attacker made to the web server configuration. If...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.
