It presents the current state of applications of artificial intelligence. It does not discuss those concepts of artificial intelligence that have become outdated and have therefore lost their rele- vance. Neither does it speculate about futuristic scenarios that do not yet exist in the field of artificial intelligence today. In other words, it is not a science fiction report but a presentation of what exists today and the developmental potential of it. It presents the subject matter in enough technical detail to enable the reader to understand at least the theoretical workings of modern AI concepts and their impact on security systems. The authors describe how a generative adversarial network (GAN) functions, what role intrusion detection systems (IDS) and intrusion prevention systems (IPS) play in the area of security, and how these GANs are deliberately being used to deceive the latter systems. 4 Management Summary This paper discusses the current state of knowledge regard- Chapter 2 discusses how artificial intelligence is used to ing the topic of artificial intelligence (AI) in security aspects assist security concepts.
