The book contains several new concepts, techniques, applications and case studies for cyber securities in parallel and distributed computing

The main objective of this book is to explore the concept of cybersecurity in parallel and distributed computing along with recent research developments in the field. Also included are various real-time/offline applications and case studies in the fields of engineering and computer science and the modern tools and technologies used. Information concerning various topics relating to cybersecurity technologies is organized within the sixteen chapters of this book.

Some of the important topics covered include:

• Research and solutions for the problem of hidden image detection
• Security aspects of data mining and possible solution techniques
• A comparative analysis of various methods used in e-commerce security and how to perform secure payment transactions in an efficient manner
• Blockchain technology and how it is crucial to the security industry
• Security for the Internet of Things
• Security issues and challenges in distributed computing security such as heterogeneous computing, cloud computing, fog computing, etc.
• Demonstrates the administration task issue in unified cloud situations as a multi-target enhancement issue in light of security
• Explores the concepts of cybercrime and cybersecurity and presents the statistical impact it is having on organizations
• Security policies and mechanisms, various categories of attacks (e.g., denial-of-service), global security architecture, along with distribution of security mechanisms
• Security issues in the healthcare sector with existing solutions and emerging threats.

Abstract

In a world ruled by speed and perfection, technology relies primarily on computer science. Be it a simple act of sending an email or a critical act of conveying billions of dollars, almost everything is merely a click away. The world of computer science keeps people engaged in activities like gaming, website surfing, social media, banking, digital citizenship, etc., with a grip spanning many domains such as hardware, software, network, data, etc. Because so many activities rely on computers, they attract criminals, which ultimately leads to cybercrime, which could be as elementary as basic hacking or as elaborate as ransomware attacks or financial cybercrimes. The consequences may vary from loss of personal or sensitive information to loss of massive amounts of money. Thus, the need to ensure cybersecurity is paramount. In this chapter, we will take a look at the concept of cybersecurity, its causes, consequences and principles. The idea of cybersecurity is not only limited to small firms and educational institutions, but also spreads across various industries and governments, making it one of the most significant areas of study. In the past, certain objectives have been proposed to safeguard such critical cyber infrastructures. Certain standards, guidelines and practices have found their place in cybersecurity frameworks to ensure that the cyber infrastructure and architecture is secure. Since the operations are multiple as well as insightful, they must be carried out by accountable personnel, such as the security administrator or incident response team, who are usually given roles in the cyber infrastructure depending on the nature of their work. Some of the anticipated roles of accountable personnel are defined in this chapter. The nature of cybercrimes over the last few years has changed drastically owing to the change in motives behind the crimes, tools and techniques involved and the overall consequences. We have observed the contrast between traditional and contemporary computer crimes over the last few years. The general evolution of cybercrimes has led to internet-based risks affecting businesses, organizations, etc,. which are potential liabilities that are harmful to property. The concept of cyber insurance is recent and promises coverage when organizations suffer internet based risks, which we have essayed in this chapter. In the later part of the chapter we will familiarize ourselves with the concept of security policies and various security models that enforce them. Few security models like the Bell La Padula and the Biba model will be discussed in this section. Further, we will acquaint ourselves with the concept of network neutrality and human rights as they go hand in hand. Keeping in mind the risks and after effects of cybercrimes, we will also explore the the legal aspect of cybercrimes by analyzing the concept of computer forensics. Some best practices pertaining to countermeasures for information warfare have also been discussed.

1.1 Introduction to Cybersecurity

Cybersecurity may be defined as the ability to defend against and recover from cyberattacks. According to the National Institute of Standards and Technology (NIST), cybersecurity is the ability to protect or defend the use of cyberspace from cyberattacks [1]. The entire cyberspace consists of several interdependent networks of the information systems infrastructure which could be the internet, telecommunications network, computer systems, embedded systems or controllers. Thus, cybersecurity is concerned with critical infrastructure, network security, cloud security, application security, the internet of things and several other domains where the need to ensure security is paramount.

1. Critical infrastructure: Security in critical infrastructure deals with cyber physical systems and real-world deployments. Industries like automation, aviation, healthcare, traffic lights, electricity grids etc are prone to cyberattacks like eavesdropping, compromised key attacks, man-in-the-middle attacks and denial-of-service attacks [2].
2. Network security: Network security deals with measures and concerns to protect information systems. It guards against unauthorized intrusions and protects the usability and integrity of network and data. cyberattacks on networks could be passi...
