This volume introduces students to the technologies and controls that protect our hardware, software, and data from cyberthreats. With everything from schools to financial accounts to vital infrastructure under threat from various bad actors, technological advances require constant new approaches to keep our businesses running, our sensitive information out of the hands of cybercriminals, and our data safe. The recent shift to remote work has increased vulnerability to cyber disruptions. The costs to societies and individuals of cyberattacks are mounting, with the FBI reporting 2022 US losses of over $10.3 billion.

Although newer tools like artificial intelligence can help with predicting cyberattacks before they occur—something traditional security professionals find challenging—these methods can also be used by hackers to learn about and exploit weaknesses in a system. Students and researchers wishing to gain a solid background in cybersecurity and related fields will find this volume an invaluable resource to developing a deeper and meaningful understanding of this important and evolving topic.

Entries are arranged alphabetically to make finding topics easy. Entries include a Fields of Study section related to the particular topic; an Abstract that provides a brief, concrete summary of the topic; Key Concepts important to a proper understanding of the topic; a detailed essay that provides an explanation of the background and significance of the topic; and Further Reading lists of up-to-date references that relate to each entry.
