本博文，是在Kali 2.0 linux里，安装OpenVAS。

前言

　　OpenVAS是一款开放式的漏洞评估工具，主要用来检测目标网络或主机的安全性。与安全焦点的X-Scan工具类似，OpenVAS系统也采用了Nessus较早版本的一些开放插件。OpenVAS能够基于C/S(客户端/服务器),B/S(浏览器/服务器)架构进行工作，管理员通过浏览器或者专用客户端程序来下达扫描任务，服务器端负载授权，执行扫描操作并提供扫描结果。

　　一套完整的OpenVAS系统包括服务器端，客户端的多个组件。

1、服务器层组件

　　openvas-scanner(扫描器):负责调用各种漏洞检测插件，完成实际的扫描操作。

　　openvas-manager(管理器):负责分配扫描任务，并根据扫描结果生产评估报告。

　　openvas-administrator(管理者):负责管理配置信息，用户授权等相关工作。

2、客户层组件

　　openvas-cli(命令行接口):负责提供从命令行访问OpenVAS服务层程序。

　　greenbone-security-assistant(安装助手):负责提供访问OpenVAS服务层的web接口，便于通过浏览器来执行扫描任务，是使用最简便的客户层组件。

　　Greenbone-Desktop-Suite(桌面套件):负责提供访问OpenVAS服务层的图形程序界面，主要允许在Windows客户机中。

除了上述各工作组件以外，还有一个核心环节，那就是漏洞测试插件更新。OpenVAS系统的插件来源有两个途径，一、官方提供的NVT免费插件，二、Greenbone Sec公司提供的商业插件。

注意啦：

　　最新版本 Kali Linux 2016.2 中不再自带OpenVAS,需要自己安装和配置

　　　也许，大家会网上看到一些博客和文档，别人的kali里有。（比如：http://blog.chinaunix.net/uid-26349264-id-4455664.html）

　　博主我用的是这款。

为什么要在Kali 2.0 linux里安装OpenVAS？

　　在kali 2.0预装的OpenVAS好像只能通过msfconsole使用（在msfconsole中load openvas)，但是这样无法创建账号，要执行db_connect时就没有账号密码去连接。如下

root@kali:~# msfconsole


msf > load openvas
[*] Welcome to OpenVAS integration by kost and averagesecurityguy.
[*] 
[*] OpenVAS integration requires a database connection. Once the 
[*] database is ready, connect to the OpenVAS server using openvas_connect.
[*] For additional commands use openvas_help.
[*] 
[*] Successfully loaded plugin: OpenVAS

msf > openvas_connect admin admin  202.193.58.13  9390 ok
[*] Connecting to OpenVAS instance at 202.193.58.13:9390 with username admin...

/usr/bin/msfconsole:48:in `<main>'
msf >

　　基于此，所以，要在kali 2.0linux里安装OpenVAS。

本博文主要介绍如何在kali Linux下对openvas 的初始安装（开始正文）

安装过程

　　Kali 2.0 linux里，先需要安装OpenVAS。

系统要求

源配置正确参考

Kali Linux 最新版本为 2016.2 ,包括 2016.1 都属于 Kali Rolling Distribution ,源是相同的建议默认使用官方源，会自动跳转到国内快速的源

　　1、设置源

编辑 /etc/apt/sources.list

nano /etc/apt/sources.list

　　清空文件内所有内容后添加

deb http://http.kali.org/kali kali-rolling main contrib non-free

　　保存退出。

也可以使用中科大的源

deb http://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib

　　2、更新

　　　　依次运行以下命令

apt-get update
apt-get upgrade
apt-get dist-upgrade

　　　　完成

安装

　　1、更新系统

apt-get update
apt-get upgrade
apt-get dist-upgrade

　　2、安装OpenVAS

apt-get install openvas

　　安装配置OpenVAS (这一步需要的时间非常久，需要下载很多文件，建议最好挂个国外代理进行这一步操作，不然你可以喝10几杯咖啡了，嘿嘿)

openvas-setup

　　检查安装 (如有提示错误的请按提示修复)

openvas-check-setup

　　比如，我

如我安装时运行 openvas-check-setup 后 step 2 有报错 ...... OK: OpenVAS Manager database is at revision 146.
OK: OpenVAS Manager expects database at revision 146.
OK: Database schema is up to date.
OK: OpenVAS Manager database contains information about 51943 NVTs.
OK: At least one user exists.
OK: OpenVAS SCAP database found in /var/lib/openvas/scap-data/scap.db.
ERROR: No OpenVAS CERT database found. (Tried: /var/lib/openvas/cert-data/cert.db)
FIX: Run a CERT synchronization script like openvas-certdata-sync or greenbone-certdata-sync.
ERROR: Your OpenVAS-8 installation is not yet complete!
Please follow the instructions marked with FIX above and run this
script again.

我实在step1和step7中出现了错误，具体错误如果不知道如何解决，可搜索引擎。

　　还记得在运行 openvas-setup 这步最后一行显示的 User created with password '47a7baeb-2f48-4fb9-9177-f6ba1fb058d8'. 嘛,这个密码显然不符合我们的使用习惯，改之

openvasmd --user admin --new-password xxxxxx

　　升级

openvas-feed-update

　　启动OpenVAS

openvas-start

　　查看 GSAD services，OpenVAS manager， OpenVAS manager 端口情况

netstat -antp | grep 939*  
tcp        0      0 127.0.0.1:9392          0.0.0.0:*               LISTEN      20764/gsad  
tcp        0      0 127.0.0.1:9390          0.0.0.0:*               LISTEN      20769/openvasmd  
tcp        0      0 127.0.0.1:9391          0.0.0.0:*               LISTEN      20773/openvassd: Wa

　　一切OK后使用浏览器访问 https://127.0.0.1:9392 应该可以看到。

　　登录账号 admin 和你前面设置的密码

配置

　　设置OpenVAS服务器的地址

　　OpenVAS 在默认配置下，仅允许 127.0.0.1 地址本地连接

openvas-stop

　　编辑 /lib/systemd/system/greenbone-security-assistant.service
