Rules and Groups employed by this XCCDF Profile
-
SRG-APP-000514-AU-002890
Group -
Splunk Enterprise must be installed with FIPS mode enabled, to implement NIST FIPS 140-2 approved ciphers for all cryptographic functions.
FIPS 140-2 precludes the use of unvalidated cryptography for the cryptographic protection of sensitive or valuable data within Federal systems. Unvalidated cryptography is viewed by NIST as providi...Rule High Severity -
SRG-APP-000148-AU-002270
Group -
Splunk Enterprise must use organization level authentication to uniquely identify and authenticate users.
To ensure accountability and prevent unauthenticated access, organizational users must be uniquely identified and authenticated to prevent potential misuse and compromise of the system. Sharing o...Rule High Severity -
SRG-APP-000148-AU-002270
Group -
Splunk Enterprise must have all local user accounts removed after implementing organizational level user management system, except for one emergency account of last resort.
User accounts should use an organizational level authentication mechanism such as SAML, LDAP, AD, etc., to provide centralized management. The use of local accounts should be discouraged, except f...Rule High Severity -
SRG-APP-000391-AU-002290
Group -
Splunk Enterprise must use an SSO proxy service, F5 device, or SAML implementation to accept the DOD common access card (CAC) or other smart card credential for identity management, personal authentication, and multifactor authentication.
The use of PIV credentials facilitates standardization and reduces the risk of unauthorized access. DOD has mandated the use of the CAC to support identity management and personal authentication f...Rule Medium Severity -
SRG-APP-000156-AU-002380
Group -
Splunk Enterprise must use HTTPS/SSL for access to the user interface.
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-000439-AU-004310
Group -
Splunk Enterprise must use SSL to protect the confidentiality and integrity of transmitted information.
Without protection of the transmitted information, confidentiality and integrity may be compromised since unprotected communications can be intercepted and either read or altered. This requiremen...Rule High Severity -
SRG-APP-000172-AU-002550
Group -
Splunk Enterprise must use LDAPS for the LDAP connection.
Passwords need to be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily c...Rule High Severity -
SRG-APP-000125-AU-000300
Group -
Splunk Enterprise must be configured to back up the log records repository at least every seven days onto a different system or system component other than the system or component being audited.
Protection of log data includes ensuring log data is not accidentally lost or deleted. Backing up log records to a different system or onto separate media than the system being audited on an organi...Rule Low Severity -
SRG-APP-000080-AU-000010
Group -
Splunk Enterprise must be configured to protect the log data stored in the indexes from alteration.
Without non-repudiation, it is impossible to positively attribute an action to an individual (or process acting on behalf of an individual). The records stored by Splunk Enterprise must be protect...Rule Medium Severity -
SRG-APP-000516-AU-000340
Group -
Splunk Enterprise must use TCP for data transmission.
If the UDP protocol is used for communication, then data packets that do not reach the server are not detected as a data loss. The use of TCP to transport data improves delivery reliability, adds d...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.
