Explore Scapy for Experimenting with Networking Environments Security

In Chapter 7 , we explored and experimented with linux capabilities, seccomp, and AppArmor features for protecting and enhancing the system security of shared infrastructures (such as data centers and cloud environments) built over the Docker hosts. In this chapter, you will learn how to inspect network protocols, applications, and traffic for exploring a variety of network security problems. Usually, carrying out network discovery and security tasks involve network traffic sniffing, spoofing, and construction of a variety of custom network tools. Hence, it is necessary to use various network security tools such as tcpdump, wireshark, Tcpreplay, tshark, Nmap, arpspoof, arping, etc. Specifically, in this chapter, you will learn a powerful and simple Python network application called Scapy for carrying out network security experiments.
