What are the Greatest Threats to Healthcare Data Security?

The healthcare industry is one of the most often targeted by cybercriminals and under threat of data theft. In 2020, the healthcare sector suffered at least one data breach per day as hackers took advantage of the vulnerabilities to gain access to the network and demand ransom.

In this article, we will explore what are the greatest threats to healthcare data security, as well as how healthcare organizations can improve their security processes so they don't become easy victims of data breaches.

Why are Healthcare Organizations a Target for Hackers?

So what makes healthcare organizations a prime target for security breaches?

Several reasons that contribute to this:

What Challenges Healthcare Providers Face in Cybersecurity?

We already mentioned a few cybersecurity challenges that healthcare providers face, but understanding these better will help the healthcare industry as a whole better react to data security threats.

A doctor may be an expert in his particular field of medicine, but when it comes to using a computer, that means nothing. If nothing else, medical professionals are often more likely to fall to phishing and other manipulation tactics by hackers

Another reason why healthcare organizations are a common target for security threats is that they lack the technical personnel trained in cybersecurity and the medical personnel often lacks basic cybersecurity literacy. This talent shortage is especially prominent in the healthcare industry

It is not uncommon for a healthcare organization to use Windows Vista or even Windows XP operating systems and outdated devices. Again, because the support for these systems is often discontinued, these are very vulnerable to data breaches

Many healthcare organizations don't even have clear policies and measures they can take to prevent a data breach, let alone mitigate healthcare data threats. In other words, they don't know what to do in case of a cyber attack

With the Covid-19 healthcare organizations are often stretched thin to save lives and 90% of their budget goes to the medical part, while IT security and other non-medical departments are often left with scraps.

What Cyber Threats Healthcare Industry Faces the Most?

There are many threats that the healthcare industry faces when it comes to cybersecurity. We'll mention a few of the biggest ones

Phishing and Malware Attacks

Of course, the healthcare industry is far from the only one vulnerable to malware and phishing attempts.

However, what makes this industry especially "interesting" to cybercriminals as we were able to see, is that they lack the personnel capable of protecting healthcare data against hackers and other threats.

In addition, healthcare organizations also struggle with outdated operating systems and IT security platforms, making the hacker's job that easier.

Unsecured Devices and Lack of User Authentication

Although we mentioned pagers as a leftover from an earlier time that only hospitals still use, naturally the use of mobile phones in the healthcare sector is becoming dominant.

The problem can occur if these devices are not secure enough and lack data encryption. Hospital WiFi networks are often public, meaning anyone, including a hacker can gain access with ease, leaving the entire organization vulnerable to malicious software.

In fact, a study showed that more than a third of healthcare organizations reported a data loss as a result of a data breach via mobile device.

Furthermore, many healthcare providers also fail to restrict access to their computers with a proper username and password at least, meaning that anyone can use them. As these computers often contain sensitive patient data, this is a serious security risk.

Internet of Medical Things (IoMT)

Speaking of security risks, many healthcare providers switched to the Internet of Medical Things (IoMT) devices that interact and often share data outside the healthcare organization.

These IoT devices often lack the necessary security to sufficiently protect sensitive data and hackers can easily access them or intercept data, leaving healthcare professionals with a serious security problem.

Staff and Vendors

We already mentioned the lack of security training and education among medical professionals, but they could also pose a different kind of internal threat.

While we believe that most are above stealing confidential data, some will do it and sell it to criminals who can then use it for blackmail and identity theft for instance.

Furthermore, the staff might also use patient credit cards as they will often have access to their financial and billing documents to commit fraud.

As for vendors that healthcare organizations work with, their workers are outside the healthcare security system and without a rigorous IT security risk assessment, can themselves be a threat.

Lost or Stolen Devices

The job of a medical professional can be hectic and in the rush, they might lose their mobile device or even get it stolen.

This can be a huge security risk as the criminal might use the device's stored login data to access the hospital's computer system.

For this reason, medical staff should, at a minimum use a strong password, multi-factor authentication and a lock-screen to protect their mobile devices in case they get lost or stolen.

In addition, knowing how to encrypt their phones can be a life-saver for doctors.


The healthcare industry is one of the most often attacked by hackers, but the lack of cyber awareness among medical providers is still a big issue.

Hopefully, this article will help you better understand the challenges and threats that a healthcare organization faces, as well as how to best improve healthcare data security against data breaches.
