Cyberattacks have been increasing worldwide and are a growing concern for health care organizations, which are ideal targets because they often have out-of-date cybersecurity systems and provide limited training for staff members on safety practices. 1,2 In a 2019 survey of 166 information security leaders at a variety of health care facilities, more than three-fourths reported experiencing a significant security event in the last year. 3 The health care sector is especially susceptible to cyberattacks because interruptions in services can have wideranging consequences; for example, disclosure of patient health information can lead to identity theft and medical fraud, and loss of personnel access to medical records can affect patient safety. 1,2,4 Cyberattacks can come from inside the organization, such as through negligent employees, or outside the organization, such as through online scam artists and attackers. 3 Facility computers or networks can be accessed through e-mail, hardware or software infected with malicious software (i.e., malware), compromised medical devices, third-party web sites, or wireless networks. 2,3 Cybersecurity threats that have had a major effect in health care include e-mail phishing and ransomware attacks. 4 According to Julie Chua, PMP, CAP, CISSP, governance, risk management, and compliance division director, U.S. Department of Health and Human Services, Washington, DC, it is important that nurses and nurse leaders have an awareness and knowledge of what cyberattacks look like and what lines of defense and response are available. "A lack of cybersecurity awareness is one of the main things that comes to mind with regard to why health care organizations are vulnerable to e-mail phishing and ransomware attacks," she said.
