Abstract
The rapid growth of the world's population is placing a huge strain on the existing infrastructures. As a quest for accommodating this growth, interest is turned to the internet of things (IoT). In fact, the IoT is significantly improving today's quality of life by innovating the provided services and enhancing communication and interaction. Furthermore, it has also empowered real-time decision making by introducing dynamic services for innovative traffic handling, energy-efficient infrastructure saving, and public safety ensuring. However, IoT applications for smart cities is still a major issue as it lacks assuring privacy and security within provided services. In this chapter, the authors pinpoint IoT's security risk assessment challenges and examine its critical influence on smart cities. Additionally, they highlight the key aspects characterizing a smart city which also represent the critical assets requiring security risk assessment. Moreover, they discuss the resulting issues and their related countermeasures.

Detection and Prevention of Fraud in the Digital Era
DoS attacks are cyber crimes where the perpetrator’s goal is to make a computer or other types of electronic devices unavailable to its users. In DoS attacks, a computer network is often overloaded with massive amounts of data in a very short time to make the servers unable to hold up the data that is being transmitted. Distributed denial of service (DDoS) attacks which often make use of botnets that can be remotely controlled are even more threatening to information systems. This helps a perpetrator to attack multiple networks and areas simultaneously. DoS and DDoS attacks can do a hefty amount of financial loss and damage the reputation of a business as people might think that the business is incapable of preventing DoS and DDoS attacks (McQuade, 2009).

Artificial Intelligence-Based Solutions for Cyber Security Problems
A DoS (denial of service) attack is a targeted attack, preventing the system from providing service and preventing users from accessing the system. Every system has a volume of network traffic it can handle. When these resources of the system are overloaded by the attackers, the system services slow down, and even the services provided by the system collapse completely as a result of these attacks.

Privacy and Security in Wireless Devices for the Internet of Things
In this method, the attacker sends unnecessary garbage requests to the server and the server gets down because of garbage requests. When an authorized user wants to access and use the server using the internet of things then the server denies the user's request. This process is called denial of service.
