SRG-APP-000516-NDM-000351
Group -
The HYCU appliance must be running a release that is currently supported by the vendor.
Network devices running an unsupported operating system lack current security fixes required to mitigate the risks associated with recent vulnerabilities.Rule High Severity -
SRG-APP-000516-NDM-000351
Group -
The HYCU server must back up audit records at least every seven days onto a different system or system component than the system or component being audited.
Protection of log data includes assuring log data is not accidentally lost or deleted. Regularly backing up audit records to a different system or onto separate media than the system being audited ...Rule Medium Severity -
SRG-APP-000516-NDM-000344
Group -
The HYCU server must obtain its public key certificates from an appropriate certificate policy through an approved service provider.
For user certificates, each organization obtains certificates from an approved, shared service provider, as required by OMB policy. For federal agencies operating a legacy public key infrastructure...Rule Medium Severity -
SRG-APP-000142-NDM-000245
Group -
The network device must be configured to prohibit the use of all unnecessary and/or nonsecure functions, ports, protocols, and/or services.
In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable...Rule High Severity -
SRG-APP-000156-NDM-000250
Group -
The network device must implement replay-resistant authentication mechanisms for network access to privileged accounts.
A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be ...Rule Medium Severity -
SRG-APP-000395-NDM-000347
Group -
The HYCU server must authenticate Network Time Protocol sources using authentication that is cryptographically based.
If Network Time Protocol is not authenticated, an attacker can introduce a rogue NTP server. This rogue server can then be used to send incorrect time information to network devices, which will mak...Rule Medium Severity -
SRG-APP-000166-NDM-000254
Group -
The HYCU server must enforce password complexity by requiring that at least one uppercase character be used.
Use of a complex passwords 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 resisti...Rule Medium Severity -
SRG-APP-000164-NDM-000252
Group -
The network device must enforce a minimum 15-character password length.
Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to d...Rule Medium Severity -
SRG-APP-000170-NDM-000329
Group -
The HYCU server must require that when a password is changed, the characters are changed in at least eight of the positions within the password.
If the application allows the user to consecutively reuse extensive portions of passwords, this increases the chances of password compromise by increasing the window of opportunity for attempts at ...Rule Medium Severity -
SRG-APP-000080-NDM-000345
Group -
The HYCU VM console must not have any default manufacturer passwords when deployed.
Virtual Machines not protected with strong password schemes provide the opportunity for anyone to crack the password and gain access to the device, which can result in loss of availability, confide...Rule Medium Severity -
SRG-APP-000400-NDM-000313
Group -
The HYCU server must prohibit the use of cached authenticators after an organization-defined time period.
Some authentication implementations can be configured to use cached authenticators. If cached authentication information is out-of-date, the validity of the authentication information may be quest...Rule Medium Severity -
SRG-APP-000179-NDM-000265
Group -
The HYCU server must use FIPS-validated algorithms for authentication to a cryptographic module and Keyed-Hash Message Authentication Code (HMAC) to protect the integrity and confidentiality of remote maintenance sessions.
Unapproved algorithms used by the cryptographic module are not validated and therefore cannot be relied on to provide confidentiality or integrity, and DoD data may be compromised. Remote maintena...Rule High Severity -
SRG-APP-000190-NDM-000267
Group -
The HYCU server and Web UI must terminate all network connections associated with a device management session at the end of the session, or the session must be terminated after 15 minutes of inactivity except to fulfill documented and validated mission requirements.
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 High Severity -
SRG-APP-000224-NDM-000270
Group -
The network device must generate unique session identifiers using a FIPS 140-2 approved random number generator.
Sequentially generated session IDs can be easily guessed by an attacker. Employing the concept of randomness in the generation of unique session identifiers helps to protect against brute-force att...Rule Medium Severity -
SRG-APP-000516-NDM-000350
Group -
The HYCU Web UI must be configured to send log data to a central log server for forwarding alerts to the administrators and the ISSO.
The aggregation of log data kept on a syslog server can be used to detect attacks and trigger an alert to the appropriate security personnel. The stored log data can used to detect weaknesses in se...Rule High Severity -
SRG-APP-000001-NDM-000200
Group -
The HYCU 4.1 application and server must limit the number of concurrent sessions to an organization-defined number for each administrator account and/or administrator account type.
Device management includes the ability to control the number of administrators and management sessions that manage a device. Limiting the number of allowed administrators and sessions per administr...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.
