Configuring the operating system to implement organization-wide security implementation guides and security checklists ensures compliance with federal standards and establishes a common security baseline across DoD that reflects the most restrictive security posture consistent with operational requirements. Configuration settings are the set of parameters that can be changed in hardware, software, or firmware components of the system that affect the security posture and/or functionality of the system. Security-related parameters are those parameters impacting the security state of the system, including the parameters required to satisfy other security control requirements. Security-related parameters include, for example: registry settings; account, file, directory permission settings; and settings for functions, ports, protocols, services, and remote connections.
For systems that are not utilizing smart card authentication, this is Not Applicable. To verify that the "login" command has been configured to require smart card authentication, run the following command: # cat /etc/pam.d/login | grep -i pam_smartcard.so If the text that returns does not include the line, "auth sufficient pam_smartcard.so" at the TOP of the listing, this is a finding.
Make a backup of the PAM LOGIN settings using the following command: sudo cp /etc/pam.d/login /etc/pam.d/login_backup_`date "+%Y-%m-%d_%H:%M"` Replace the contents of "/etc/pam.d/login" with the following: # login: auth account password session auth sufficient pam_smartcard.so auth optional pam_krb5.so use_kcminit auth optional pam_ntlm.so try_first_pass auth optional pam_mount.so try_first_pass auth required pam_opendirectory.so try_first_pass auth required pam_deny.so account required pam_nologin.so account required pam_opendirectory.so password required pam_opendirectory.so session required pam_launchd.so session required pam_uwtmp.so session optional pam_mount.so
