Hands-On Data Analysis with Pandas

Summary

In our second application chapter, we learned how to simulate events in Python and got additional exposure to writing packages. We also saw how to write Python scripts that can be run from the command line, which we used to run our simulation of the login attempt data. Then, we performed some exploratory data analysis on the simulated data to see if we could figure out what would make hacker activity easy to spot.

This led us to zero in on the number of distinct usernames attempting to authenticate per IP address per hour, as well as the number of attempts and failure rates. Using these metrics, we were able to create a scatter plot, which appeared to show two distinct groups of points, along with some other points connecting the ...
