Summary

We have gone through the basics of packet crafting and sniffing with various Python modules, and saw that Scapy is very powerful and easy to use. By now we have learned the basics of socket programming and Scapy. During our security assessments, we may need the raw outputs and access to basic levels of packet topology so that we can analyze and make decisions ourselves. The most attractive part of Scapy is that it can be imported and used to create networking tools without going to create packets from scratch.

We will discuss application fingerprinting with Python in more detail in the next chapter.
