This volume introduces students to the technologies and controls that protect our hardware, software, and data from cyber threats. 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.
