CENTOS上的网络安全工具（二十六）SPARK+NetSA Security Tools容器化部署(2)

        〇、抓包与批量转换cap文件

       1. Network Monitor 抓包

        我们在CENTO OS上的网络安全工具（十七）搭建Cascade的Docker开发环境中捎带脚介绍了以下windows下的抓包软件。大意就是微软又一款不错的抓包分析软件，名曰nmcap，可在Download Microsoft Network Monitor 3.4 (archive) from Official Microsoft Download Center下载

          而且，这个软件有个不错的不间断抓包功能，使用如下命令可对所有网卡（如果对指定网卡，可以先用displaynetwork命令查出网卡序号进行指定）抓包，并根据指定大小将文件编号存储在给定的路径下：

PS C:\Users\lhyzw> nmcap /DisplayNetwork

Network Monitor Command Line Capture (nmcap) 3.4.2350.0

0. vEthernet (WSL) (Hyper-V Virtual Ethernet Adapter)

1. WLAN (MediaTek Wi-Fi 6 MT7921 Wireless LAN Card)

2. * 3 (Microsoft Wi-Fi Direct Virtual Adapter #3)

3. * 4 (Microsoft Wi-Fi Direct Virtual Adapter #4)

4.  (Realtek PCIe GbE Family Controller)

PS C:\Users\lhyzw> nmcap /Network * /Capture /File d:\downlaod\test.chn:2MB

Network Monitor Command Line Capture (nmcap) 3.4.2350.0

Saving info to: d:\downlaod\test.cap - using chain captures of size 2.00 MB.

        2. 批量转换cap文件

        不幸的是network monitor抓取的文件采用nmcap格式存放，yaf并不支持这个格式。好在windows下，还有一个著名的wireshark软件可以完成这个转换工作。

        wireshark软件的安装目录下自带名为editcap.exe的文件，可以用来转换：

C:\Program Files\Wireshark>editcap -F pcap -T ether g:\pcap\testmine(2).cap  g:\t\testmine(2).pcap

        其中，-F标识转换后的格式，-T标识转换前的格式。使用-F或者-T携带空的参数，可以打印出editcap所支持的所有格式。然后指定输入文件和输出文件，即可以实现转换。

        不幸在于editcap仅支持一分多、多合一和一对一，我并没有找到可批量转换的参数。最后逼不得已只能上批处理了。在cap文件所在目录下vim（因为前面为了编译hadoop我装了个gitbash嘛）一个test.bat文件如下：        

for /r . %%i in (*.cap) do C:\Progra~1\Wireshark\editcap -F pcap -T ether %%i g:\t\%%~ni.pcap

        就一行，含义是对当前目录下的所有后缀为cap的文件，使用editcap（注意绝对路径，因为并没有将其加入PATH环境变量中）进行转换，转换后文件名，使用%~ni，即提取%i变量所对应的文件名进行构造。

        然后执行test.bat就可以实现批量转换了：

G:\pcap>test.bat

G:\pcap>for /R . %i in (*.cap) do C:\Progra~1\Wireshark\editcap -F pcap -T ether %i g:\t\%~ni.pcap

G:\pcap>C:\Progra~1\Wireshark\editcap -F pcap -T ether G:\pcap\testmine(103).cap g:\t\testmine(103).pcap

G:\pcap>C:\Progra~1\Wireshark\editcap -F pcap -T ether G:\pcap\testmine(104).cap g:\t\testmine(104).pcap

G:\pcap>C:\Progra~1\Wireshark\editcap -F pcap -T ether G:\pcap\testmine(105).cap g:\t\testmine(105).pcap

G:\pcap>C:\Progra~1\Wireshark\editcap -F pcap -T ether G:\pcap\testmine(106).cap g:\t\testmine(106).pcap

G:\pcap>C:\Progra~1\Wireshark\editcap -F pcap -T ether G:\pcap\testmine(107).cap g:\t\testmine(107).pcap

        一、编译YAF3

        首先声明，为了偷懒，并没有在centos7环境下做下面的事情。所以下面的编译操作是在centos stream 8的环境下进行的。

        1. 编译环境安装

        按照官网的指南，首先安装编译环境

[root@bogon share]# yum install gcc gcc-c++ make pkgconfig -y

        或者直接使用群组安装方式，将所有的开发工具安装上去，大约需下载170MB左右

[root@bogon share]# yum -y group install "Development Tools"

        2. 抓包依赖库安装

        libpcap依赖库很容易安装，在centos stream 8下，只需要yum install就行了

[root@bogon share]# yum install libpcap -y

        但是libpcap-devel库在centos stream 8下没有，不安装的话会在编译时产生找不到pcap.h头文件的错误。因此需要手工下载安装。

        直接到pkgs.org网站https://pkgs.org/download/libpcap-devel上下载：

        或者启动Powertools库后安装：

[root@bogon share]# dnf config-manager --set-enabled powertools

        或者直接在参数中指定powertools库。需要注意的是，按照官方的说法，这个库在某些版本的Centos中叫做“PowerTools”…… 

[root@bogon share]# dnf --enablerepo=powertools install libpcap-devel

完毕！
[root@bogon share]# 

        3. 其它依赖库安装

        （1）GLib-2.0

        按照官方的说法，GLib实际被包含在了大多数操作系统的基础环境中，我们只需要检查一下安装了没有：

[root@bogon share]# rpm -qa|grep glib
avahi-glib-0.7-20.el8.x86_64
ModemManager-glib-1.18.2-1.el8.x86_64

glibc-langpack-zh-2.28-228.el8.x86_64
pulseaudio-libs-glib2-14.0-2.el8.x86_64
libappstream-glib-0.7.14-3.el8.x86_64
glib2-2.56.4-158.el8.x86_64
json-glib-1.4.4-1.el8.x86_64
glibc-common-2.28-228.el8.x86_64

glibc-devel-2.28-228.el8.x86_64
PackageKit-glib-1.1.12-6.el8.x86_64
dbus-glib-0.110-2.el8.x86_64
taglib-1.11.1-8.el8.x86_64
glib-networking-2.56.1-1.1.el8.x86_64
glibc-gconv-extra-2.28-228.el8.x86_64
libvirt-glib-3.0.0-1.el8.x86_64
glibc-headers-2.28-228.el8.x86_64
glibc-langpack-en-2.28-228.el8.x86_64
poppler-glib-20.11.0-4.el8.x86_64
glibc-all-langpacks-2.28-228.el8.x86_64

        貌似是都装了，但是一个大坑在这：

[root@bogon libfixbuf-3.0.0.alpha2]# yum install glib2-devel -y

         如果没有装这个开发版本的话，执行./configure时仍然会报错，而且只告诉你你的glib版本不高于2.18……，所以找起来那是相当生气。

        （2）libfixbuf

        YAF3对应3.0版本的libfixbuf，这个需要我们预先编译号。源代码包在此处fixbuf — Latest Downloads (cert.org)下载

         1）准备源代码

[root@bogon ~]# tar zxvf libfixbuf-3.0.0.alpha2.tar.gz 
[root@bogon ~]# cd libfixbuf-3.0.0.alpha2/
[root@bogon libfixbuf-3.0.0.alpha2]# 

        2）安装依赖

        除了glib2和glib2-devel以外，如果需要加入openssl支持（--with-openssl），则系统也需要安装openssl和openssl-devel。

        如果需要SCTP支持（--with-sctp），也需要实现使内核支持SCTP协议。

        为了确保我们编译的库最大可能的兼容性，此处我们还是能减则减了。

        3）配置libfixbuf

        由于仅需要更新libfixbuf库，所以使用了--disable-tools参数

[root@bogon libfixbuf-3.0.0.alpha2]# ./configure --disable-tools
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
………………

    * Linker flags (LDFLAGS):       
    * Libraries (LIBS):             -lssl -lcrypto -lpthread 

        4）make && make install libfixbuf

        由于我们没有在configure时指定--prefix和--exe-prefix参数，所以使用了默认目录安装，后期可能会设计更改LIBDIR环境变量。

[root@bogon libfixbuf-3.0.0.alpha2]# make && make install
Making all in src
make[1]: 进入目录“/root/libfixbuf-3.0.0.alpha2/src”

Libraries have been installed in:

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking

        4. 编译安装

        （1）准备YAF3源码

        下载并解压源码：

         （2）configure YAF3

        为了避免复杂性，很多可选的支持我们都没有选，要实现DPI支持所必须的--enable-applabel和--enable-dpi是不能丢的，另外捎带着我们也选了plugin、entropy和zlib，看看后面有没有用上的机会。

        （3）make && make install YAF3

      make && make install以后，同样，需要到默认目录下去寻找编译结果

 /usr/bin/mkdir -p '/usr/local/lib'
 /bin/sh ../libtool   --mode=install /usr/bin/install -c   libyaf.la '/usr/local/lib'
libtool: install: /usr/bin/install -c .libs/libyaf-3.0.0.alpha2.so.4.0.0 /usr/local/lib/libyaf-3.0.0.alpha2.so.4.0.0
libtool: install: (cd /usr/local/lib && { ln -s -f libyaf-3.0.0.alpha2.so.4.0.0 libyaf-3.0.0.alpha2.so.4 || { rm -f libyaf-3.0.0.alpha2.so.4 && ln -s libyaf-3.0.0.alpha2.so.4.0.0 libyaf-3.0.0.alpha2.so.4; }; })
libtool: install: (cd /usr/local/lib && { ln -s -f libyaf-3.0.0.alpha2.so.4.0.0 libyaf.so || { rm -f libyaf.so && ln -s libyaf-3.0.0.alpha2.so.4.0.0 libyaf.so; }; })
libtool: install: /usr/bin/install -c .libs/libyaf.lai /usr/local/lib/libyaf.la
libtool: finish: PATH="/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/root/bin:/sbin" ldconfig -n /usr/local/lib
----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

          （4）测试执行：

[root@bogon yaf-3.0.0.alpha2]# yaf --version

        二、编译super mediator

[root@bogon ~]# tar zxvf super_mediator-2.0.0.alpha2.tar.gz
[root@bogon ~]# cd super_mediator-2.0.0.alpha2/
[root@bogon super_mediator-2.0.0.alpha2]# ./configure --with-mysql --with-zlib
[root@bogon super_mediator-2.0.0.alpha2]# make && make install
…………………………
make[4]: 进入目录“/root/super_mediator-2.0.0.alpha2/src”
 /usr/bin/mkdir -p '/usr/local/bin'
  /usr/bin/install -c super_mediator '/usr/local/bin'
 /usr/bin/mkdir -p '/usr/local/share/man/man1'
 /usr/bin/install -c -m 644 super_mediator.1 super_mediator.conf.1 '/usr/local/share/man/man1'
make[4]: 离开目录“/root/super_mediator-2.0.0.alpha2/src”
make[3]: 离开目录“/root/super_mediator-2.0.0.alpha2/src”

make[2]: 进入目录“/root/super_mediator-2.0.0.alpha2/etc”
 /usr/bin/mkdir -p '/usr/local/etc'
 /usr/bin/install -c -m 644 super_mediator.conf '/usr/local/etc'
make[2]: 对“install-data-am”无需做任何事。
make[2]: 离开目录“/root/super_mediator-2.0.0.alpha2/etc”
make[1]: 离开目录“/root/super_mediator-2.0.0.alpha2/etc”
Making install in doc
make[1]: 进入目录“/root/super_mediator-2.0.0.alpha2/doc”
…………………………

        同样，我们选择平平无奇的安装，不过虽然这里我们选择了--with-mysql，后面检查版本的时候任然被报没有mysql支持，可能是选项没选够的原因吧。

        如果此时直接执行测试，大概率会找不到libfixbuf.so文件：

[root@bogon local]# super_mediator --version
super_mediator: error while loading shared libraries: libfixbuf.so.10: cannot open shared object file: No such file or directory

        其主要原因其实已经在前面的编译结果中了。也就是 环境变量'LD_LIBRARY_PATH'必须被设置到/usr/local/lib上：

        在~/.bashrc文件中添加环境变量，并且source一下就好了。

# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

export LTDL_LIBRARY_PATH=/usr/local/lib/yaf
export LD_LIBRARY_PATH=/usr/local/lib

         此时，再执行super_mediator --version就没问题了：

[root@bogon local]# super_mediator --version
super_mediator version 2.0.0.alpha2
Build Configuration: 
    * Fixbuf version:                   3.0.0.alpha2
    * MySQL support:                    NO
    * OpenSSL support:                  NO
    * SiLK IPSet support:               NO

        之所以要编译super-mediator，原因就在这里，因为yaf3需要libfixbuf3支持，libfixbuf3对应的super mediator版本至少应该是2。 

        三、测试使用YAF3+Super_mediator

        既然是测试，我们还是从一开始就整最简单的用法。看看自找麻烦的编译后是不是获得了DPI的加持。

        简单的对一个pcap文件进行转IPFIX处理，其中设定applable为[53，80，443]。对应去查内置的applabel号，代表对DNS、Http和TLS协议进行解析。不过貌似我的样例数据中没有足够完整的Http数据，所以最终只得到了DNS和TLS相关的数据。

        【这个命令是错的，文末分解】

[root@bogon pcap]# yaf --in /root/share/pcap/test2.pcap --out /root/test.yaf --dpi --dpi-select=[80,53,443] --applabel --max-payload=2048
[2023-06-25 09:35:14] Rejected 63574 out-of-sequence packets.

         然后使用super_mediator进行提取转换，也就是简单的讲IPFIX数据转换为TEXT类型输出。

[root@bogon ~]# super_mediator -o result.txt -m text test.yaf
Initialization Successful, starting...
[2023-06-25 09:39:18] Running as root in --live mode, but not dropping privilege

        简单查看一下数据，这个和官方文件中的描述是一致的。也就是流数据以时间开始的一行，和流相关的元数据在流数据的下面追加行：

         使用grep看一下tls类元数据：

        能够看出元数据采取了“表名“+”information element id“+”data“的记法：

        表明其实对应的就是app label，ie id=31，代表cRLDistributionPoints （吊销证书列表发布点），32代表CertificatePolicies 证书策略对象。

        三、镜像化YAF3+Super-mediator

        一致觉得NetSA的官方支持做得不好，依靠官方的安装部署指南部署总会遇到大大小小的问题，需要通读大量说明文档和熟练掌握Linux系统才有可能解决。至少，如上在Centos stream 8上安装的过程就有不少问题，而安装官方的指南，在CentOS 7上的安装会遇到更多莫名的问题。

        经过一系列磕磕绊绊的尝试，总算在下面这种情况下配通了，不过好多我想用的配置项没法打开，因为打开就会报错，且我还不知道时什么东西没装齐整，或者什么东西装错版本了。比如，按照官方的说法，只安装gcc、gcc-c++、pkgconfig、make是无法完成libfixbuf的编译的，而整个“Development Tools”包的安装就没有问题……

        Dockerfile文件如下：    

FROM centos:centos7

#RUN yum install gcc gcc-c++ make pkgconfig -y
RUN yum group install "Development Tools" -y
RUN yum install libpcap libpcap-devel -y
RUN yum install glib2 glib2-devel -y
RUN yum install zlib zlib-devel -y

        四、测试使用mothra

        简单的mothra使用似乎不涉及从cert网站上下载源码编译等等之类的过程。仅仅需要在搭建好的spark-shell环境——比如我们前面搭建过的windows下的spark环境进行操作即可。

        一般来说，这个过程总会有点小坎坷，比如说有若干jar包安装不上，但命名这些包就是在maven repository centra中能找到的，我也不知到为什么：

         下载完成后放到错误信息所指定的那个目录中：

        【这一段的说法是错的】不过看起来只有流数据被存在ipfix文件中，DPI数据似乎并没有被导入进来。其实折腾mothra的目的就是希望官方驱动源能够帮助我们将dpi信息导入spark，如果只是流数据，依赖SiLK工具集就够用，完全没必要折腾spark。可能ipfix的导出格式就不支持dpi信息吧，具体为何我也不知，只能下回分解了。

        【这是一个悲伤的故事】后面我们打算再开一篇仔细分解以下如何查看“完整”的DPI信息。然而，即使是把下一篇的问题都解决了，按照上面的过程，也无法得到http的DPI信息——除了AppLabel=80这种情况下的http元数据没有被提取出来，dns和ssl的元数据都已经被提取出来了。所以我花了好几天的时间来排查——包括在高铁上的时间……最终发现这个错误在于使用--applabel参数的时候相当然的用[]将applabel框了起来——而官方的指南中式不需要带这个中括号的。然而结果就是，yaf程序并不会报错，而是将“[80”识别为一个applabel——那自然式不存在的，所以从--verbose信息中显示，它只解析了2个protocol：

         所以，正确的命令应该是：

         如此，在spark中就可以看到完整的http信息了：
