Machine Learning for Cybersecurity Cookbook

By: Emmanuel Tsukerman

Overview of this book

Organizations today face a major threat in terms of cybersecurity, from malicious URLs to credential reuse, and having robust security systems can make all the difference. With this book, you'll learn how to use Python libraries such as TensorFlow and scikit-learn to implement the latest artificial intelligence (AI) techniques and handle challenges faced by cybersecurity researchers. You'll begin by exploring various machine learning (ML) techniques and tips for setting up a secure lab environment. Next, you'll implement key ML algorithms such as clustering, gradient boosting, random forest, and XGBoost. The book will guide you through constructing classifiers and features for malware, which you'll train and test on real samples. As you progress, you'll build self-learning, reliant systems to handle cybersecurity tasks such as identifying malicious URLs, spam email detection, intrusion detection, network protection, and tracking user and process behavior. Later, you'll apply generative adversarial networks (GANs) and autoencoders to advanced security tasks. Finally, you'll delve into secure and private AI to protect the privacy rights of consumers using your ML models. By the end of this book, you'll have the skills you need to tackle real-world problems faced in the cybersecurity domain using a recipe-based approach.

Malicious URL detector

Malicious URLs cause billions of dollars of damage every year by hosting spam, malware, and exploits, as well as stealing information. Traditionally, defenses against these have relied on blacklists and whitelists – lists of URLs that are considered malicious, and lists of URLs that are considered safe. However, blacklists suffer from a lack of generality and an inability to defend against previously unseen malicious URLs. To remedy the situation, machine learning techniques have been developed. In this recipe, we'll run a malicious URL detector using character-level recurrent neural networks with Keras. The code is based on https://github.com/chen0040/keras-malicious-url-detector.
