SRG-APP-000001-NDM-000200
Group -
ONTAP must be configured to limit the number of concurrent sessions.
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 -
ONTAP must automatically audit account-enabling actions.
Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply...Rule Medium Severity -
ONTAP must be configured to display the Standard Mandatory DoD Notice and Consent Banner before granting access to the device.
Display of the DoD-approved use notification before granting access to the network device ensures privacy and security notification verbiage used is consistent with applicable federal laws, Executi...Rule Medium Severity -
ONTAP must allocate audit record storage capacity in accordance with organization-defined audit record storage requirements.
Audit records are stored on staging volumes when auditing is enabled. If the staging volumes do not exist when auditing is enabled, the auditing subsystem creates the staging volumes. These volumes...Rule Medium Severity -
ONTAP must be configured to synchronize internal information system clocks using redundant authoritative time sources.
The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run mode) and increasingly inaccurate time stamps on audit events and other ...Rule Medium Severity -
ONTAP must enforce access restrictions associated with changes to the device configuration.
Failure to provide logical access restrictions associated with changes to device configuration may have significant effects on the overall security of the system. When dealing with access restrict...Rule Medium Severity -
ONTAP 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 -
ONTAP must authenticate NTP sources using authentication that is cryptographically based.
If Network Time Protocol (NTP) 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 wi...Rule Medium Severity -
ONTAP 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 -
ONTAP must enforce password complexity by requiring that at least one uppercase character be used.
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 -
ONTAP must enforce password complexity by requiring that at least one numeric character be used.
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 -
ONTAP must terminate all network connections associated with a device management session at the end of the session, or the session must be terminated after 10 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-000190-NDM-000267
Group -
SRG-APP-000003-NDM-000202
Group -
ONTAP must be configured to create a session lock after 15 minutes.
A session lock is a temporary network device or administrator-initiated action taken when the administrator stops work but does not log out of the network device. Rather than relying on the user to...Rule Medium Severity -
SRG-APP-000319-NDM-000283
Group -
SRG-APP-000148-NDM-000346
Group -
ONTAP must be configured with only one local account to be used as the account of last resort in the event the authentication server is unavailable.
Authentication for administrative (privileged-level) access to the device is required at all times. An account can be created on the device's local database for use when the authentication server i...Rule Medium Severity -
SRG-APP-000033-NDM-000212
Group -
ONTAP must enforce administrator privileges based on their defined roles.
To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems must be properly configured to incorporate ...Rule High Severity -
SRG-APP-000340-NDM-000288
Group -
ONTAP must prevent non-privileged users from executing privileged functions to include disabling, circumventing, or altering implemented security safeguards/countermeasures.
Preventing non-privileged users from executing privileged functions mitigates the risk that unauthorized individuals or processes may gain unnecessary access to information or privileges. Privileg...Rule High Severity -
SRG-APP-000065-NDM-000214
Group -
ONTAP must be configured to enforce the limit of three consecutive failed logon attempts.
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.Rule Medium Severity -
SRG-APP-000068-NDM-000215
Group -
SRG-APP-000357-NDM-000293
Group -
SRG-APP-000360-NDM-000295
Group -
ONTAP must have audit guarantee enabled.
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. With audit guarantee enabled, all SMB operations must generate an audit...Rule Medium Severity -
SRG-APP-000373-NDM-000298
Group -
SRG-APP-000374-NDM-000299
Group -
ONTAP must record time stamps for audit records that can be mapped to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT).
If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by the application include date and time. Tim...Rule Medium Severity -
SRG-APP-000380-NDM-000304
Group -
SRG-APP-000516-NDM-000336
Group -
ONTAP must be configured to use an authentication server to provide multifactor authentication.
Centralized management of authentication settings increases the security of remote and nonlocal access methods. This control is particularly important protection against the insider threat. With ro...Rule High Severity -
SRG-APP-000516-NDM-000340
Group -
ONTAP must be configured to conduct backups of system level information.
System-level information includes default and customized settings and security attributes, including ACLs that relate to the network device configuration, as well as software required for the execu...Rule Medium Severity -
SRG-APP-000516-NDM-000344
Group -
ONTAP must use DoD-approved PKI rather than proprietary or self-signed device certificates.
Each organization obtains user certificates from an approved, shared service provider as required by OMB policy. For federal agencies operating a legacy public key infrastructure cross-certified wi...Rule Medium Severity -

Group -
ONTAP must be configured to authenticate SNMP messages using FIPS-validated Keyed-HMAC.

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.
