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

Time series decomposition

Time series decomposition is a better way of understanding the data in hand. Decomposing the model creates an abstract model that can be used for generalization of the data. Decomposition involves identifying trends and seasonal, cyclical, and irregular components of the data. Making sense of data with these components is the systematic type of modeling.

In the following section, we will look at these recurring properties and how they help analyze time series data.

Level

We have discussed moving averages with respect to time series before. The level can be defined as the average or mean of a bunch of time series data points.
