Percentage reporting breaches more than doubled from 2016 report
Thales, a leader in critical information systems, cybersecurity and data security, announces the results of its 2018 Thales Data Threat Report, Healthcare Edition, issued in conjunction with analyst firm 451 Research. Nearly half (48%) of U.S. healthcare respondents reported getting breached in the last year alone – more than 2.5X the rate from only two years ago – and 56% report feeling either ‘very’ or ‘extremely’ vulnerable to data breaches. Further, more than three-fourths (77%) of U.S. healthcare respondents reported at least one breach at some time in the past. This is the highest percentage among all U.S. vertical industries polled in this year’s report.
Digital transformation: Enabling better healthcare, but creating risks
In an effort to provide more efficient services – and with an eye towards cutting costs – the healthcare industry has more recently been turning its attention towards embracing digitally transformative technologies, including cloud, big data, the IoT and containers. These technologies allow organizations to better create and manage data, as well as store critical information more efficiently.
Almost all (95%) of global respondents reported using these technologies with sensitive data. With each new technology comes unique data security challenges that must be addressed, as they increase the attack surface available. Among some of the more notable findings from this year’s report:
- All (100%) U.S. respondents surveyed are leveraging cloud technologies, with 63% using three or more cloud vendors for infrastructure (IaaS) as opposed to having it onsite
- Over half (58%) of U.S. respondents are using more than 50 cloud based software applications (SaaS); and 52% are using three or more cloud based platform (PaaS) environments
- Almost all (96%) of U.S. respondents are using big data; 90% are working on or using mobile payments, and 92% have a blockchain project implemented or are in the process of implementing one
- 92% are leveraging IoT devices, which may include internet-connected heart-rate monitors, implantable defibrillators and insulin pumps
Consequently, these organizations have emerged as a prime target for hackers, putting valuable medical data at risk. While a stolen credit card has a time-limited value, PHI and electronic medical records (EMR) are packed with immutable data that can, and do, fetch hundreds of dollars per stolen record on illegal online markets.
Compliance continues to play role in influencing U.S. healthcare security attitudes
In the U.S., the Health Insurance Portability and Accountability Act (HIPAA) is the most impactful and well-known healthcare regulation. While HIPAA covers off on audit trail requirements, secure archival of protected health information (PHI), tightly controlled access to PHI, and many other regulations, it just doesn’t provide organizations with detailed instructions on how to accomplish these requirements. Despite HIPAA’s limitations, 70% of U.S. respondents believe compliance requirements are ‘very’ or ‘extremely’ effective at preventing data breaches. Almost half (44%) of U.S. respondents report compliance is a top spending driver. While sizable, that number has dropped considerably from last year (57%).
Encryption viewed as critical – but does spending reflect this?
In the U.S., encryption is the top choice for complying with privacy regulations (42%), followed distantly by tokenization (19%) and migrating customer data (10%). Encryption tools are also three of the top four data security tools being deployed this year, with 65% of U.S. respondents leveraging data masking; 65% identity and access management; 59% database and file encryption; and 57% encryption in the cloud.
Despite encryption’s proven effectiveness at protecting large data sets, many organizations remain stubbornly focused on network and endpoint security. While the federal sector (77%), financial services (88%), and retail industries (89%) recognize encryption as the first or second most effective data security tool, 75% of U.S. healthcare respondents ranked data-at-rest defenses (such as encryption or tokenization) second to last in effectiveness. At 34%, data-at-rest defenses are still at the bottom of the spending priority list, as well.
Peter Galvin, Chief Strategy Officer, Thales says:
“When it comes to data security, the U.S. healthcare industry is increasingly under duress, which is why some of this year’s findings are so counterintuitive. For example, 62% of U.S. respondents are investing money in endpoint security, even though it’s rated least effective at protecting data. An alarmingly high number of U.S. respondents (39%) also report storing sensitive data in SaaS apps. Data protection strategies need to match U.S. healthcare’s reality – which is that of an industry embracing digitally transformative technologies – in the form of encryption solutions offering protection to sensitive data that has moved beyond the traditional four walls of the healthcare environment.”
