Defining Actions for Packets
Explore how to use Python Scapy to analyze and define specific actions for multiple types of network packets, such as HTTP and DNS. Learn to create dynamic responses appropriate for honeypots or servers, enhancing network monitoring and interaction capabilities.
We'll cover the following...
Introduction
Previously, we used Scapy’s sniff function to monitor traffic flowing over the network. With sniff, we can use BPF filters to identify packets of interest and send them to a function for further processing and analysis.
However, our current code only prints the contents of the packet. It doesn’t process the packet itself or take different actions for different types of packets.
This capability is essential if we want to build honeypots or servers using Python and Scapy. If we receive a SYN packet, we need to respond with a SYN/ACK. Alternatively, a honeypot receiving a DNS request might want to log the ...
