Ensure sshd Banner is configured

НискаНиво 1Аутоматскаaix

Опис

The Banner parameter specifies a file whose contents must be sent to the remote user before authentication is permitted. By default, no banner is displayed. Banners are used to warn connecting users of the particular site's policy regarding connection. Presenting a warning message prior to the normal user login may assist the prosecution of trespassers on the computer system. Audit: evaluates the effective configuration from `sshd -T` (Match blocks must be reviewed separately).

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

Edit the /etc/ssh/sshd_config file to set the parameter above any Match set entries as follows: Banner /etc/ssh/ssh_banner Re-cycle the sshd daemon to pick up the configuration changes: stopsrc -s sshd startsrc -s sshd Note: First occurrence of a option takes precedence, Match set statements withstanding. Edit the file being called by the Banner argument with the appropriate contents according to your site policy.
