A recent Ponemon Institute survey has revealed 62% of healthcare organizations have experienced a data breach in the past 12 months. More than half of those organizations experienced data loss as a result.
The Merlin International sponsored survey was conducted on 627 healthcare industry leaders from hospitals and payer organizations. 67% of respondents worked in hospitals with 100-500 beds and had an estimated 10,000 to 100,000 networked devices.
Last year more than 5 million healthcare records were exposed or stolen, and the healthcare was the second most targeted industry behind the business sector. 2017 was the fourth consecutive year that the healthcare industry has been second for data breaches and there are no signs that cyberattacks are likely to reduce over the coming year.
Even though there is a high probability of experiencing a cyberattack, 51% of surveyed organizations have yet to implement an incident response program. This lack of preparedness can hamper recovery if a cyberattack is experienced. As the Cost of a Data Breach Study by the Ponemon Institute showed, a fast response to a data breach can limit the harm caused to breach victims and reduce the cost of mitigating such an attack. Respondents reported that the cost of mitigating an attack and dealing with the fallout from a network compromise was approximately $4 million.
When asked about the biggest threats to their organization and the types of attack that caused the most concern there was little to choose between internal and external threats, which were rated as a top concern by 64% and 63% of respondents respectively. The main perceived targets for hackers were electronic medical records (77%), patient billing information (56%), login credentials (54%), other authentication credentials (49%), and research information (45%).
The methods used to gain access to networks and data were highly varied. The main method of attack was the exploitation of software and operating system vulnerabilities and the use of malware. 71% of respondents said vulnerabilities were exploited while 69% said attacks involved the use of malware. 37% of organizations had experienced ransomware attacks.
The security of medical devices is a major concern, especially since they are a blind spot in many organizations. 65% of respondents said medical devices were not included in their overall cybersecurity strategy or they didn’t know if they were. 31% of respondents said they did not have any plans to include medical devices in their cybersecurity strategies in the near future.
The HHS’ Office for Civil Rights has raised awareness of the need to provide ongoing security awareness training to staff and companies such as Cofense have published data to show how security awareness training and phishing simulations can greatly reduce susceptibility to phishing attacks. However, many healthcare organizations are not heeding that advice and are not providing training regularly. Many healthcare organizations are still only providing security awareness training to employees annually. It is therefore unsurprising that 52% of respondents said a lack of employee security awareness was hampering their ability to improve their security posture.
74% believed the biggest obstacle preventing them from improving security was staffing issues and 60% said they do not have staff with the right cybersecurity qualifications in-house. 51% of respondents said that have not yet appointed a Chief Information Security Officer (CISO).
