Edge Testing your Hadoop Environment

DZone's Guide to

Edge Testing your Hadoop Environment

An in-depth guide to securing your Hadoop environment by testing from the edge.

Discover how to provide active runtime protection for your web applications from known and unknown vulnerabilities including Remote Code Execution Attacks.

You can run the attack library for OSX or Linux from an edge node or from outside the cluster. I ran against mine from my OSX laptop against my cluster that I had network access to. You should try to scan from inside your network, from an edge node and from a remote site on the Internet.

You will need Python 2.7 or Python 3.x installed first:

 git clone git@github.com:CERT-W/hadoop-attack-library.git

pip install requests lxml 

You may need root or sudo access to install on your machine. One of the scanners hits the WebHDFS link that you may have seen a warning about.

 python hdfsbrowser.py timscluster 

Beginning to test services accessibility using default ports ...

To see how available your Hadoop configurations are, you can use Hadoop Snooper. This is under: Tools\Techniques\and\Procedures\Getting\the\target\environment\configuration.

python hadoopsnooper.py timscluster -o test

Specified destination path does not exist, do you want to create it ? [y/N]y

[+] Creating configuration directory

[+] core-site.xml successfully created

[+] mapred-site.xml successfully created

[+] yarn-site.xml successfully created

This downloads all those configuration files to a directory named test.

These were not the full configuration files, but they pointed to correct internal servers and give an attacker more information.

Another scan worth running is SQLMap. This tool will let you check various SQL tools in the system. SQLMap requires Python 2.6 or 2.7.

SQLMap is awesome for testing any RDBMS, the more you know about it the better to stress it.  MySQL and PostgreSQL are often used to host metadata for Hadoop and can be tested with SQLMap. Remember Bobby Tables.
