Ensure sshd LogLevel is configured
説明
SSH provides several logging levels with varying amounts of verbosity. The DEBUG options are specifically not recommended other than strictly for debugging SSH communications. These levels provide so much data that it is difficult to identify important security information, and may violate the privacy of users. Audit: evaluates the effective configuration from `sshd -T` (Match blocks must be reviewed separately).

修正方法

Edit the /etc/ssh/sshd_config file to set the parameter above any Match set entries as follows: LogLevel VERBOSE - OR - LogLevel INFO 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.
