Splunk Enterprise must be configured to 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 Low Severity -

Splunk Enterprise must be configured to enforce a minimum 15-character password length.
The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Password complexity, or strength, is a measure of the effectivene...Rule Low Severity -

Group -
Splunk Enterprise must be installed in FIPS mode to implement NIST FIPS-approved cryptography 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 -

Splunk Enterprise must accept the DOD CAC or other PKI credential for identity management and personal 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 High Severity
