A cyberattack is an attempt by cybercriminals as individuals or organizations with unauthorized access using one or more computers and computer systems to steal, expose, change, disable or eliminate information, or to breach computer information systems, computer networks, and computer infrastructures. Cyberattackers gain a benefit from victims, which may be criminal such as stealing data or money, or political or personal such as revenge. In cyberattacks, various targets are possible. Some potential targets for businesses include business and customer financial data, customer lists, trade secrets, and login credentials.

Cyberattackers use a variety of methods to gain access to data, including malware such as viruses, worms, and spyware and phishing methods, man-in-the-middle attacks, denial-of-service attacks, SQL injection, zero-day exploit, and DNS tunneling.

Related to cyberattack, the term cyberwarfare is gaining popularity nowadays. Cyberwarfare is the use of cyberattacks by a state or an organization to cause harm as in warfare against another state's or organization's computer information systems, networks, and infrastructures.

Military, civil, and ideological motivations, or hacktivism can be used to launch a cyberwarfare. For these reasons, cyberwarfare may be used to conduct espionage, sabotage, propaganda, and economic disruption.

Considering highly digitalized business processes such as e-mails, digital banking, online conference, and digital manufacturing methods, damage of cyberwarfare to businesses and countries are unavoidable. As a result, developing strategies for defending against cyberattacks and cyberwarfare is critical for businesses. The concepts of cyberattack and cyberwarfare, as well as business strategies to be protected against them will be discussed in this chapter.

Technology-facilitated abuse, so-called “tech abuse,” through phones, trackers, and other emerging innovations, has a substantial impact on the nature of intimate partner violence (IPV). The current chapter examines the risks and harms posed to IPV victims/survivors from the burgeoning Internet of Things (IoT) environment. IoT systems are understood as “smart” devices such as conventional household appliances that are connected to the internet. Interdependencies between different products together with the devices' enhanced functionalities offer opportunities for coercion and control. Across the chapter, we use the example of IoT to showcase how and why tech abuse is a socio-technological issue and requires not only human-centered (i.e., societal) but also cybersecurity (i.e., technical) responses. We apply the method of “threat modeling,” which is a process used to investigate potential cybersecurity attacks, to shift the conventional technical focus from the risks to systems toward risks to people. Through the analysis of a smart lock, we highlight insufficiently designed IoT privacy and security features and uncover how seemingly neutral design decisions can constrain, shape, and facilitate coercive and controlling behaviors.

In the current scenario, cybersecurity issues have emerged to be a major challenge for firms to deal with. The increased use of technologies has increased radically the volume and typology of information produced, exchanged, and managed by firms thus creating conditions for cybersecurity incidents or information breaches. In this situation, it becomes paramount for firms to recognize cybersecurity risks and be prepared to prevent them through the implementation of approaches and technologies able to ensure a high level of protection.

In this chapter, we provide a framework for analyzing and managing cybersecurity risks. We employed a case study strategy to understand how the risk analysis process is carried out within an Information Security company. The study and observations obtained from this case study have permitted to define a framework useful for SME to deal with cybersecurity issues.

Purpose: Small and medium enterprises (SMEs) are the most significant contributors to maximum employment generation, the gross domestic product (GDP) of many countries, and the overall global economy. It is also evident that cyber threats are becoming a big challenge for SMEs, which is directly impacting global economy.

Methodology: Existing research inputs were accessed to understand current cyber threats for SMEs and their cybersecurity posture. Additionally, this research has collected the latest insights by taking direct inputs from SMEs and conducting a well-designed research survey. It has provided a few direct inputs to designing solutions for the SME segment. For analysis and recommendations, cybersecurity best practices and core cybersecurity concepts are considered at the centre of the solution.

Findings: Implementing existing cybersecurity standards or frameworks is not easy for SMEs, as they generally have limited resources and different priorities for their business when it comes to the implementation of any cybersecurity controls. Currently, many cybersecurity standards are not able to support the implementation of business domain-specific controls.

Practical implications: Along with the research findings shared in this chapter, as a resolution to the problems faced by SMEs, the authors will propose a new framework as a solution. This framework is designed using core concepts of cybersecurity such as confidentiality, integrity, and availability (CIA triad) as well as defence in depth (DiD) mechanisms in each layer of organisation. The authors will also share a high-level idea about how reliable artificial intelligence-based software can help identify recommended controls for particular SMEs.

Cyber threats present constantly evolving and unique challenges to national security professionals at all levels of government. Public and private sector entities also face a constant stream of cyberattacks through varied methods by actors with myriad motivations. These threats are not expected to diminish in the near future. As a result, homeland security and national security professionals at all levels of government must understand the unique motivations and capabilities of malicious cyber actors in order to better protect against and respond to cyberattacks. This chapter outlines the most common cyberattacks; explains the motivations behind these attacks; and describes the federal, state, and local efforts to address these threats.

Introduction: The frequency and complexity of cyber assaults have grown in recent years. Consequently, organisations have increased their expenditures in more robust infrastructure to protect themselves from these cyber assaults. These organisations’ assets, data, and reputations are at risk due to rapidly increasing cybercrimes. However, complete protection from these many and ever-changing threats is very challenging as a result. To deal with them, companies are taking steps to reduce risks and limit company losses in their occurrence.

Purpose: Progressively, the insurance sector organisations are including digital protection as a component of the board’s general danger technique. Protection enterprises, then again, depend on accurately expecting risks, while a significant number of them depend on normalised approaches. Because of the exceptional attributes of the digital assaults, transporters now and again depend on subjective strategies dependent on master decisions. There is an unmistakeable absence of observational information on digital protection, specifically subjective examinations planning to comprehend and depict necessities, impediments, and cycles applicable for digital protection.

Methodology: There are various unanswered inquiries and worries about the oversight and legitimate and administrative assessment of network safety weaknesses in the protection business. In the wake-up of looking over all these worries and issues, steps to alleviate them are laid out after an extensive literature survey and secondary data sources. In this study, the authors have principally viewed the executive parts of the associations as the danger. While considering network protection, their insight of needs was taken as one among a few dangerous treatment systems, just as the necessities of the organisations’ protection in assessing the danger level of likely customers.

Findings: This section analyses past research in network safety and information security in the protection market. The danger of the executives’ strategies, the numerical models, and the forecasts of digital occassions are illustrated in this section. Lastly, the future headings are likewise expressed momentarily.

Practical implications: This review might be valuable for additional examination and logical discussion, yet additionally for down-to-earth applications. Moreover, it could be gainful to organisations as a supportive instrument for better agreement on what digital protection is and how to get ready to take on network safety and information security procedures in the association.

Significance: These associations’ resources, information, and notoriety are in danger because of quickly expanding cybercrimes. Cybercriminals are utilising more refined approaches to start digital assaults. Digital protection was anticipated to affect security conduct before any proof was gathered. Progressively, organisations are including digital protection as a feature of their general danger to the executive system. Because of the exceptional attributes of the digital assaults, transporters as often as possible depend on subjective methods dependent on master decisions. Thus, this space of network safety and information security is vital uniquely in the protection market.
