Title: Prevalence of DNSSEC for hospital websites in Illinois,
Abstract: The domain name system translates human friendly web addresses to a computer
readable internet protocol address. This basic infrastructure is insecure and
can be manipulated. Deployment of technology to secure the DNS system has been
slow, reaching about 20% of all web sites based in the USA. Little is known
about the efforts hospitals and health systems make to secure the domain name
system for their websites. To investigate the prevalence of implementing Domain
Name System Security Extensions (DNSSEC), we analyzed the websites of the 210
public hospitals in the state of Illinois, USA. Only one Illinois hospital
website was found to have implemented DNSSEC by December, 2017.
