AOSX-14-000024
(in versions v2 r6 through v1 r1)
Title
The macOS system must display the Standard Mandatory DoD Notice and Consent Banner before granting access to the system via SSH. (Cat II impact)
Discussion
Display of a standardized and approved use notification before granting access to the operating system ensures privacy and security notification verbiage used is consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. System use notifications are required only for access via logon interfaces with human users and are not required when such human interfaces do not exist. The banner must be formatted in accordance with DTM-08-060. Satisfies: SRG-OS-000023-GPOS-00006, SRG-OS-000024-GPOS-00007
Check Content
For systems that allow remote access through SSH, run the following command to verify that "/etc/banner" is displayed before granting access: # /usr/bin/grep Banner /etc/ssh/sshd_config If the sshd Banner configuration option does not point to "/etc/banner", this is a finding.
Fix Text
For systems that allow remote access through SSH, modify the "/etc/ssh/sshd_config" file to add or update the following line: Banner /etc/banner
