Hands-On Machine Learning for Cybersecurity

By: Soma Halder, Sinan Ozdemir

Overview of this book

Cyber threats today are one of the costliest losses that an organization can face. In this book, we use the most efficient tool to solve the big problems that exist in the cybersecurity domain. The book begins by giving you the basics of ML in cybersecurity using Python and its libraries. You will explore various ML domains (such as time series analysis and ensemble modeling) to get your foundations right. You will implement various examples such as building system to identify malicious URLs, and building a program to detect fraudulent emails and spam. Later, you will learn how to make effective use of K-means algorithm to develop a solution to detect and alert you to any malicious activity in the network. Also learn how to implement biometrics and fingerprint to validate whether the user is a legitimate user or not. Finally, you will see how we change the game with TensorFlow and learn how deep learning is effective for creating models and training systems

Using Data Science to Catch Email Fraud and Spam

Spam detection

We will now deal with a hands-on exercise of separating spam emails a set of non-spam, or ham, emails. Unlike manual spam detectors, where users mark email as spam upon manual verification, this method uses machine learning to distinguish between spam and ham emails. The stages of detection can be illustrated as follows:

Types of mail servers

Mail servers are meant to receive email items, and they consist of a return path. The path bounces an email off to the ID mentioned in the return path. Mail servers are equivalent to the neighborhood mailman. All emails pass through a series of servers called mail-servers through series of processes.

The different types of mail servers are as follows:

  • POP3 email servers...
