1./etc/motd
操作：echo " Authorized users only. All activity may be monitored and reported " > /etc/motd
效果：telnet和ssh登录后的输出信息
2. /etc/issue和/etc/issue.net
操作：echo " Authorized users only. All activity may be monitored and reported " > /etc/issue.net
效果：telnet主机未登录时输出的信息
3./etc/syslog.conf--远程日志服务配置文件
4./etc/sysctl.conf--操作系统配置文件
5./etc/vsftpd/vsftpd.conf--vsftpd配置文件
6./etc/ssh/sshd_config--ssh配置文件
7./etc/hosts.allow和/etc/hosts.deny--服务连接白名单/黑名单文件
8./etc/pam.d/system-auth--系统登录验证配置文件
9./etc/init/control-alt-delete.conf--ctrl+alt+del快捷键启用/禁用
10./etc/profile--环境变量配置文件，通常用于配置UMASK和TMOUT
11./etc/login.defs--口令（长度及有效时长等）配置文件
12.基线合规配置脚本（IP注意修改）
