Healthcare Data Security: The Overview of Threats and Safety Measures

Through the lens of Tech4Good, Debra explains why we have to be the change we want to see in the world.

One’s experience with healthcare is often a very sensitive issue to discuss. Few people want their personal health information to be seen by anyone else but a medical service provider. Thus, data privacy is a major concern among the people who consider using online custom healthcare solutions.

As a service provider, can you make sure that the privacy of your users and patients is safe? Sure you can, but on the 4 conditions:

  • if you understand why healthcare data security should be your highest priority and what are the threats,
  • if you learn the basics of data security in healthcare industry,
  • if you follow the legal data protection guidelines,
  • and if you trust your project only to a decent team of developers.

Too many if’s? Let’s look through them one-by-one. This article will be your health care data guide.

Why Information Safety Should Be a Priority?

Healthcare systems contain three types of valuable information:

Medical data

The right to privacy is one of the basic human rights. Health is what most people choose to keep private. Should it be a physical illness or a mental disorder, people are often embarrassed to talk about their problems because diseases are never appealing or pleasant. For this reason, people want to keep medical data private.

If such patient information is disclosed, a lot of psychological and social harm can be done. The fact that health information is accessed by strangers can make patients anxious or depressed. Also, if it goes public, especially if the person is a celebrity or a well-known politician, it may badly damage their reputation. Finally, healthcare organizations that allowed for one’s medical data to be leaked will face legal problems and reputational damage.

Financial data

Not only personal health information or other medical records can be found in a healthcare system. It may also contain valuable financial data. If a wrongdoer obtains access to this healthcare data, lots of patients, doctors, or the institution itself may have their money stolen.

Personal data

Also, a healthcare system contains some personal data, such as addresses, phone numbers, or e-mails. In case it is stolen, these credentials can be used to break into one’s social media profiles. This data can be sold for targeted marketing purposes so that a person will constantly receive annoying advertising calls or messages. In the worst-case scenario, a person can fall victim to blackmailers, harassers, or persecutors. 

What Are the Threats?

Healthcare cybersecurity can be affected by a range of factors:

Cyber criminals

As I explained earlier, electronic health records are very sensitive data by their nature. Who may need it? Hackers may try to breach the system in order to get private information about some people, which can later be used for blackmailing or defamation. They may also sell it to advertisers or use it for personal purposes, for instance, to obtain prescription medication.

More than that, if cyber offenders break into the system, they may install ransomware, which would hinder the normal functioning of the application or platform. In this case, the healthcare institution will have to pay a ransom, which may be a huge sum of money. A money loss combined with a bitter experience of being the victim of cyber crime absolutely does not work in favor of the healthcare business or its patients.

Unsecured hardware or network

The unsecured network connection or general-access computers also impose a significant risk because they are susceptible to being breached. If a business decides to save money on installing a fully-protected web network, secure hardware, and high-quality medical devices, they risk losing much more as the result of a data breach.

System errors

Medical data should be stored for many years since health records need to be comprehensive for future treatments to be efficient and effective. As a result, medical systems deal with an immense amount of data. A single system error can result in the loss of all the vital information. Therefore, ensuring that the system can withstand heavy data load is another important data security measure to be taken. In addition, the malfunction of the healthcare app, either caused deliberately or happening accidentally, may negatively affect the patient outcome. The system may stop responding in case of emergency, compile wrong medical recipes, give wrong recommendations, or fail to detect a problem. In medical settings where the slightest mistake can cause health complications or even be fatal, malfunctioning must be prevented by all means.

Corrupt employees

People you work with also pose a threat to healthcare data security. Surely, the hiring and training process is organized in a way that it should identify all the suspicious people. However, you can never be a hundred percent sure that all your colleagues are honest and loyal. The ability to access patient data can give your corrupt employees an opportunity to abuse power. To prevent this, the system should have different levels of data access and an admin page.

Time waste

And another very important risk, which is particularly topical for the healthcare industry cyber security, is a waste of time. No second should be wasted when it comes to patient treatment, especially in urgent cases. The healthcare security measures that you choose to implement to ensure protection from all the threats mentioned above should be carried out automatically, seamlessly, and instantly. Your employees should be trained to act immediately and decisively, and your healthcare system should be technically sound.

What Is Healthcare Data Security?

Data security is a set of information safety measures including regular risk assessment, employee training, and technical security solutions.

Prior research and regular risk assessment

When designing a healthcare system, you need to consider all the stages of system usage in order to identify weak spots and potential healthcare cybersecurity loopholes. For this reason, you should conduct a comprehensive discovery stage, and a professional Business Analyst or UX designer can help you with it. Moving on, as the world of technology is advancing, cyber criminals become more and more skilled. You should conduct a regular risk assessment and management sessions to make sure that your healthcare security system is up-to-date and the application or web platform is impervious to healthcare data breaches.

Employee training

The staff should be trained to understand the importance of health data security, to recognize phishing attempts, to identify hazardous web pages or files, to clean the computer system, and to act properly in case of a system error. Healthcare organizations should conduct regular training sessions and workshops to make sure that all employees are on the same page, well-aware of how important patient data loss prevention measures are, and devoted to the organization.

Technical security solutions


Information should be encrypted to be accessed or decoded only by users with the right key. This is how unwarranted users will not be able to access sensitive data. The data encryption can be conducted with a symmetric or asymmetric key — your development team will help you choose the more appropriate method. You may also encrypt your private network with the help of a VPN (Virtual Private Network) tool. This way, nobody outside your network will see the data coming in or out of your computer. Network security protocols, such as Secure Hypertext Transfer Protocol (HTTPS), Secure File Transfer Protocol (SFTP), and Secure Socket Layer (SSL), also serve this important purpose.


To ensure data loss prevention and to be immune to ransomware, you should regularly back up your data. By implementing a regular database dump, you will make sure that no patient data is ever lost as you will always be able to restore the previous version. It is a very important measure from the perspective of data protection in healthcare industry.


Another healthcare data security solution is to develop a system to track user behavior. Logging all the actions taking place in the system may help you analyze the performance of your platform. In case an error occurs or an internal data leak happens, you can easily find the guilty party by looking through the logs.


Outdated software creates numerous loopholes for cyber criminals. If the application or platform is regularly updated and constantly supported, the system is less susceptible to offenders. Also, it is advisable to encourage all the employees to update their system passwords on a monthly basis.

What About the Law?

Following legal requirements is another security measure, which healthcare organizations need to take. This topic is so important and large-scale that it is worth a different article to observe the topic. Here, I will try to go through the essential legal healthcare data security standards.

When developing a healthcare system, it is vital to ensure that it complies with HIPAA security rules, GDPR, and local laws, as well as to request the signature of patient consent.

HIPAA security rules

HIPAA security rules serve four basic functions: keeping electronic health records secure, keeping health information private, simplifying administrative processes, and ensuring insurance portability. The Health Insurance Portability and Accountability Act was introduced in 1996 to ensure data security in healthcare industry. It deals with the safety of medical information of both patients and service providers. Healthcare data security is its highest priority, so it comprises three types of regulations: administrative, physical, and technical. 


GDPR (The General Data Protection Regulation) is a set of rules introduced in 2016 by the European Union for the purpose of ensuring data privacy and protection. The regulations are universal and concern all businesses regardless of the industry or field they operate in. Thus, they are also a must-follow for healthcare organizations. 

Local laws

Local laws differ from state to state, from city to city. It is important for healthcare organizations to be aware of the local legal requirements and to make sure that their systems closely follow them in order to prevent issues with law enforcement.

Patient consent

Patient consent is an important legal tool, the aim of which is to ensure that both a patient and a healthcare institution are on the same page in terms of how the patient data is going to be used. A proper healthcare system should inform the user about its data security policies. Signing patient consent, the user confirms that they understand and agree with the healthcare information security and privacy policies.

Who to Trust?

To make sure that healthcare data is safe and secure, healthcare organizations should choose technical experts with a transparent and ethical approach to providing medical software development services.

To develop a healthcare mobile app or a web platform that will be both safe and helpful, healthcare organizations need to have two types of expertise: medical and technical. Few people are lucky enough to have both, and it is absolutely normal. While you are doing your best to handle healthcare-related tasks, find a custom software development company to assist you with the technical aspect.

If you want your future software product to be reliable, high-quality, and safe for a user, while coming at a reasonable cost, find a vendor with an ethical approach to software development and healthcare cybersecurity. If you trust KeenEthics, we will gladly become this vendor for you!
