Download or read book Cybersecurity in the COVID 19 Pandemic written by Kenneth Okereafor and published by CRC Press. This book was released on 2021-03-17 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the 2020 global lockdown became a universal strategy to control the COVID-19 pandemic, social distancing triggered a massive reliance on online and cyberspace alternatives and switched the world to the digital economy. Despite their effectiveness for remote work and online interactions, cyberspace alternatives ignited several Cybersecurity challenges. Malicious hackers capitalized on global anxiety and launched cyberattacks against unsuspecting victims. Internet fraudsters exploited human and system vulnerabilities and impacted data integrity, privacy, and digital behaviour. Cybersecurity in the COVID-19 Pandemic demystifies Cybersecurity concepts using real-world cybercrime incidents from the pandemic to illustrate how threat actors perpetrated computer fraud against valuable information assets particularly healthcare, financial, commercial, travel, academic, and social networking data. The book simplifies the socio-technical aspects of Cybersecurity and draws valuable lessons from the impacts COVID-19 cyberattacks exerted on computer networks, online portals, and databases. The book also predicts the fusion of Cybersecurity into Artificial Intelligence and Big Data Analytics, the two emerging domains that will potentially dominate and redefine post-pandemic Cybersecurity research and innovations between 2021 and 2025. The book’s primary audience is individual and corporate cyberspace consumers across all professions intending to update their Cybersecurity knowledge for detecting, preventing, responding to, and recovering from computer crimes. Cybersecurity in the COVID-19 Pandemic is ideal for information officers, data managers, business and risk administrators, technology scholars, Cybersecurity experts and researchers, and information technology practitioners. Readers will draw lessons for protecting their digital assets from email phishing fraud, social engineering scams, malware campaigns, and website hijacks.

Download or read book Pediatric Gender Assignment written by Stephen A. Zderic and published by Springer Science & Business Media. This book was released on 2003-01-31 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the proceedings from a conference that took place in Dallas in the spring of 1999 which was entitled "Pediatric Gender Assignment - A Critical Reappraisal". Some participants rightfully argued that the conference really focused on the issue of pediatric gender assignment, and that reassignment was not applied in most cases. Their comments were reflected in the title of this monograph. This multidisciplinary meeting was sponsored by a conference grant from the National Institutes of Health, and a broad inquiry into this complex topic took place from many points of view. Basic scientists offered insight into mechanisms of sexual differentiation of the gonads, physical phenotype and imprinting of the central nervous system. Endocrinologists reviewed their experience in diagnosis and management, surgeons described traditional as well as innovative approaches, and there was strong representation from the ethical and behavioral sciences. In putting together such a panel, it was essential that we identify a cast of speakers who could address their viewpoints with strong convictions, and yet not let their passions render the meeting counter productive. We were not disappointed. While many differing points of view were firmly expressed by the panelists and audience, all viewpoints were accorded the respect they deserved. The concept behind the meeting and this book really originated in 1997 shortly after Diamond and Sigmundson published their long term follow up study of the John/Joan case.

Download or read book Context Sensitive Health Informatics Many Places Many Users Many Contexts Many Uses written by E.M. Borycki and published by IOS Press. This book was released on 2015-08-14 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Context is key in the design, implementation and evaluation of health information technology. Healthcare systems around the world are in transition; adopting technologies to deal with the problems of aging populations, increased numbers of chronically ill patients and limited resources. But a 'one size fits all' approach is not the answer, and may limit those local healthcare system innovations that are so crucial to the development of health informatics. Even the most advanced systems will fail to achieve the desired outcomes if context is not taken into account. This book presents the proceedings of the Context Sensitive Health Informatics (CSHI) conference, held in Curitiba, Brazil, in August 2015. Context sensitive health informatics is about health information technologies and their environments, and the 26 papers included here examine how health informatics systems are developed, implemented and evaluated in a complex environment of many places, many users, many uses and in many contexts. The book is divided into four themes: different users in different contexts; evaluating for context through usability testing and ensuring patient safety; organizational and social issues in different places; and understanding different contexts using theory. This overview of the research and experience critical to ensuring the successful introduction and adaptation of healthcare systems to new countries, contexts and healthcare settings will be of interest to all those involved in improving the quality of healthcare worldwide.
