Lynis是用于基于Unix和Linux的系统的安全审核工具。它协助审核员扫描系统，其安全防御措施有助于改善系统的安全性。该软件将确定特定于OS类型，已安装软件包，系统和网络配置的系统信息。此外，它将检查系统是否存在配置错误和安全问题。本文介绍了如何在Ubuntu上安装lynis。
它是一个开源的
它支持shell脚本
没有依赖
容易明白
动态操作系统检测
它支持300多种内置测试
它支持自定义测试
插件支持

广泛的软件支持
Lynis不需要任何安装，可以直接从任何目录使用。为了更好地练习，请在/ usr / local / lynis下为Lynis创建目录，如下所示–
# mkdir /usr/local/lynis
下载Lynis源文件的稳定版本，如下所示–
# cd /usr/local/lynis # wget https://cisofy.com/files/lynis-2.2.0.tar.gz
样本输出应如下所示–

要运行Lynis，它需要root用户权限，并将输出写入/var/log/lynis.log文件。使用以下命令运行Lynis-
# cd lynis # ./lynis
上面的命令将为您提供可用参数的完整列表，如下所示-

要启动Lynis进程，必须定义–check-all参数以开始扫描整个Linux系统，如下所示–
# ./lynis --check-all
样本输出应如下所示–

要为系统的每日扫描报告创建Lynis cronJobs，请使用以下命令-
# crontab -e
样本输出应如下所示–
# crontab -e# Edit this file to introduce tasks to be run by cron. # # Each task to run has to be defined through a single line # indicating with different fields when the task will be run # and what command to run for the task # # To define the time you can provide concrete values for # minute (m), hour (h), day of month (dom), month (mon), # and day of week (dow) or use '*' in these fields (for 'any').# # Notice that tasks will be started based on the cron's system # daemon's notion of time and timezones. # # Output of the crontab jobs (including errors) is sent through # email to the user the crontab file belongs to (unless redirected). # # For example, you can run a backup of all your user accounts # at 5 a.m every week with: # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
添加以下行以每天晚上10:30运行cron作业
3022***root /path/to/lynis -c -Q --auditor "automated" --cronjob
更新Lynis，请使用以下命令-
# ./lynis update info [Show update details] # ./lynis update release [Update Lynis release]
