Overview of this book

Today's organizations spend billions of dollars globally on cybersecurity. Artificial intelligence has emerged as a great solution for building smarter and safer security systems that allow you to predict and detect suspicious network activity, such as phishing or unauthorized intrusions. This cybersecurity book presents and demonstrates popular and successful AI approaches and models that you can adapt to detect potential attacks and protect your corporate systems. You'll learn about the role of machine learning and neural networks, as well as deep learning in cybersecurity, and you'll also learn how you can infuse AI capabilities into building smart defensive mechanisms. As you advance, you'll be able to apply these strategies across a variety of applications, including spam filters, network intrusion detection, botnet detection, and secure authentication. By the end of this book, you'll be ready to develop intelligent systems that can detect unusual and suspicious patterns and attacks, thereby developing strong network security defenses using AI.

AI in the context of cybersecurity

With the exponential increase in the spread of threats associated with the daily diffusion of new malware, it is practically impossible to think of dealing effectively with these threats using only analysis conducted by human operators. It is necessary to introduce algorithms that allow us to automate that introductory phase of analysis known as triage, that is to say, to conduct a preliminary screening of the threats to be submitted to the attention of the cybersecurity professionals, allowing us to respond in a timely and effective manner to ongoing attacks.

We need to be able to respond in a dynamic fashion, adapting to the changes in the context related to the presence of unprecedented threats. This implies not only that the analysts manage the tools and methods of cybersecurity, but that they can also correctly interpret and evaluate the...
