| # 5.2.7 Ensure SSH HostbasedAuthentication is disabled (Scored) |
| # |
| # Profile Applicability |
| # --------------------- |
| # - Level 1 - Server |
| # - Level 1 - Workstation |
| # |
| # Description |
| # ----------- |
| # The HostbasedAuthentication parameter specifies if authentication is allowed through |
| # trusted hosts via the user of .rhosts , or /etc/hosts.equiv , along with successful public |
| # key client host authentication. This option only applies to SSH Protocol Version 2. |
| # |
| # Rationale |
| # --------- |
| # Even though the .rhosts files are ineffective if support is disabled in /etc/pam.conf , |
| # disabling the ability to use .rhosts files in SSH provides an additional layer of protection . |
| # |
| # Audit |
| # ----- |
| # Run the following command and verify that output matches: |
| # |
| # # grep "^HostbasedAuthentication" /etc/ssh/sshd_config |
| # HostbasedAuthentication no |
| # |
| # Remediation |
| # ----------- |
| # Edit the /etc/ssh/sshd_config file to set the parameter as follows: |
| # |
| # HostbasedAuthentication no |
| |
| parameters: |
| openssh: |
| server: |
| host_auth: False |
