Healthcare systems have undergone a rapid digital transformation in recent years, largely owing to Covid19 pandemic. The adoption of telemedicine and electronic health records as well as systemwide integration of advanced information technologies have tremendously increased the effectiveness and efficiency of health services delivery. However, alongside this digital transition, the entire sector has become widely exposed to cybersecurity threats. Cybersecurity in digital health has far-reaching consequences. From financial losses and delays in treatment to compromised privacy, endangered patient lives, and disruption in service delivery – negative outcomes of cyber incidents are manyfold.
Healthcare has become a key target for cyberattacks due to the sensitive nature of health data. According to IBM, the health sector experienced the most expensive data breaches in 2023, with a total cost of approximately US$ 10.93 million. This is almost double that of the financial industry. Nearly 80% of the information targeted by cyberattacks is personal data. What’s more, in the healthcare sector it takes longer than any other sector to capture a possible security breach. Globally, it takes 329 days on average for a healthcare institution to detect a data breach.
The more integrated health systems become, the louder the call for cybersecurity measures within them. It is in this regard that technical security controls need to be stringent, incident response plans widespread, and cybersecurity awareness among the general public and health professionals ramped up.
Cybersecurity in Digital Health and Its Key Components
One of the biggest assets that an organization could probably have is the corporate information and the technology that handles and stores it. The health sector, particularly, houses very sensitive personal information that is highly coveted by cybercriminals due to its value on the black market.
Cybersecurity is a set of security measures that help with safeguarding IT assets, systems, networks, computers, and even the documents in digital format from attacks in cyberspace. Its main goal is to protect sensitive information from unauthorized access, use, disclosure, disruption, modification, or destruction. There are various types of tools available that are commonly used in securing the digital health ecosystem. These can be broadly categorized under regulatory frameworks, control measures, and guidelines.
The main components of cybersecurity in digital health include:
- Network security – to protect health network from external threats such as e.g., malware, ransomware, or phishing.
- Regulatory compliance – to protect personal data and ensure privacy in line with legal requirements.
- Incident response and recovery – to establish protocols and plans in response to cyberattacks, data breaches, or system failures.
- Medical device security – to safeguard connected medical devices, like pacemakers or infusion pumps, from cyber threats that could compromise patient safety.
Types of Cybersecurity Threats in Healthcare
Cyberattacks in healthcare can take a variety of forms. These are evolving alongside cybercrime and becoming more sophisticated as time passes. Key threats include:
- Phishing – email phishing is the most widely spread of the kind that targets healthcare providers. Hackers persuade their victims to transmit critical information by employing sophisticated social engineering techniques. Afterward, this data is either sold or utilized to steal identities.
- Data breaches – healthcare suffers a large amount of data breaches compared to other industries. These account to an average of 1.76 breaches per day. Personal health information can be stolen due to unauthorized access to medical records, putting patients at risk of financial fraud and identity theft.
- Ransomware– relies on the use of a virus, oftentimes a trojan worm, that infects computers and encrypts all of the data stored on them. Afterward, cybercriminals extort a ransom to decrypt vital medical data. These viruses have grown so sophisticated that, in most cases, only their creators are able to eradicate them. Massive disruptions were caused by the WannaCry ransomware assault in 2017, which impacted healthcare companies globally.
- Denial-of-service (DoS) Attacks – intend to cause a server crash and render it unusable for the duration of the attack. Millions of pings are sent to the server, typically via emails. DoS attacks are most commonly initiated as a form of protest against the governments and their official sites. However, if a hospital falls victim to such an attack the results can be catastrophic – even a single hour of hampered service might cause irreparable damage. The hackers who initiate these DoS pings often demand a ransom to release affected systems.
- Insider Threats: These cyber threats are mostly accidental in nature, largely caused by the lack of awareness among employees. The health staff inadvertently may facilitate data theft or the installation of malware on devices. Such incidents may lead to sensitive data being compromised or a network’s functioning getting affected.
Key Challenges in Securing and Maintaining Cybersecurity in Digital Health
As healthcare continues to digitize, the stakes for cybersecurity will only increase. There are a few challenges on the way to maintaining cybersecurity in digital health including:
- Systems interoperability – The healthcare sector extensively relies on interconnected systems and devices. Each of these comes with different security protocols and vulnerabilities. Ensuring data exchange in diverse a ecosystem is challenging from a cybersecurity perspective.
- Data privacy – normally data privacy is governed by national laws and regulations of the given country. However, as telemedicine evolves and healthcare crosses borders, compliance enforcement becomes difficult.
- Outdated systems and infrastructure – many healthcare organizations still rely on old systems and infrastructure. These are not accustomed to evolving cyber threats, thus leaving open doors for various attacks.
- Lack of resources – many health service providers, especially smaller ones, struggle with securing the necessary funding to implement or upgrade cybersecurity measures.
How to Strengthen Cybersecurity in Digital Health?
A secure digital health environment can only be achieved via a systematic approach. It starts with the implementation of robust data protection and access control mechanisms. Healthcare organizations should prioritize the encryption of all sensitive patient information, be this in transit or at rest. This is to ensure that even if data is intercepted, it remains unreadable.
Multi-factor authentication and role-based access control can limit system access to authorized personnel only. Such limitation helps reduce the risk of internal breaches. What’s more, healthcare providers must regularly update and patch their systems to address any vulnerabilities. Conducting regular security audits and penetration testing have proven to be increasingly useful as well.
Besides those technical measures, it is of utmost importance to instill cybersecurity awareness into the fabric of the organizational culture. Training on identifying cyber risks and attacks has to be an ongoing process among healthcare personnel. Technology and education must converge to empower healthcare organizations and help them build a strong line of defense against cybercrime.
