Information
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 for an emergency account of last resort.
The use of local accounts instead of organizational level accounts creates a risk where accounts are not properly disabled or deleted when users depart or their roles change.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
Select Settings >> Access Controls >> Users.
Delete any user account with Authentication system set to Splunk, with the exception of one emergency account of last resort. Splunk will prevent the user from deleting an LDAP account.
