Mastering Python for Networking and Security

Introduction to gathering information

The process of collecting information can be automated using both modules that are installed by default in the Python distribution and external modules that are installed in a simple way. Some of the modules that we will see allow us to extract information from servers and services that are running – information such as domain names and banners.

There are many ways to gather information from servers:

• We can use Shodan to extract information from public servers
• We can use the socket module to extract banner information from public and private servers
• We can use the DNSPython module to extract information from DNS servers
• We can use the pywebfuzz module to obtain possible vulnerabilities
