Protecting Patient Privacy: Top 5 AppSec Trends in Healthcare for 2023

by GuardRails on April 28, 2023

The field of healthcare has witnessed an unprecedented growth and advancement in the past few years, thanks to the widespread adoption of technological innovations. From electronic health records (EHRs) to telemedicine, the healthcare industry has come a long way in embracing technology to enhance patient care delivery. However, with increased digitization and connectivity come new challenges related to cybersecurity and data privacy. The healthcare sector is one of the most targeted industries by cybercriminals, and data breaches can have far-reaching consequences on patient safety and trust. The need for robust application security (AppSec) measures has never been more important. In this blog post, we will explore the top five AppSec trends that are shaping the future of healthcare cybersecurity.

Types of Health Information Technology

Health information technology (HIT) can be defined as any technology that is used to store, retrieve, and exchange health information. There are several types of HIT that are commonly used in healthcare settings:

Electronic health records (EHR) allow healthcare professionals to access patient records quickly and easily, improving patient care and reducing errors.
Telemedicine allows remote consultations and care, especially helpful for patients in rural or underserved areas.
Health information exchange (HIE) allows for secure sharing of patient data between healthcare organizations.
Picture Archiving and Communication Systems (PACS) and Vendor-Neutral Archives (VNAs) process and store patients’ medical images.
Clinical decision support (CDS) systems provide physicians with evidence-based recommendations for patient care.
Patient portals allow patients to access their own medical records and communicate with healthcare professionals.
Health information analytics (HIA) allows organizations to collect large amounts of health data and analyze it to improve patient outcomes and overall quality of care.

It is essential for healthcare organizations to understand and utilize these types of HIT in order to provide patients with the highest quality care possible.

Leading Causes of Healthcare Data Breaches

Healthcare data breaches continue to be a significant issue in the industry, and the consequences of these breaches are dire, ranging from financial loss to reputational damage and even putting patients’ lives at risk. It is crucial for organizations to stay vigilant and proactive in identifying potential vulnerabilities and threats to their systems. We have identified several leading causes of data breaches:

Insider threats
Phishing attacks
Ransomware attacks
Hacking
Unauthorized access
Physical theft or loss
Vendor-related incidents

By being aware of these causes and implementing the necessary security measures, healthcare organizations can prevent or mitigate the risks of data breaches in the industry.

Impact of Data Breaches in Healthcare

Regal Medical Group recently disclosed that over 3.3 million patients had their personal and health information exposed in a December 2022 ransomware cyberattack. The US Department of Health and Human Services says the breach is currently the biggest reported to it in 2023. Information stolen in the breach included names, Social Security numbers, dates of birth, addresses, diagnoses and treatment information, laboratory test results, prescription data, radiology reports, health plan member numbers, and phone numbers.

Meanwhile, HIPAA reports that 2022 saw a total of 11 reported healthcare data breaches of more than 1 million records in 2022 and a further 14 data breaches of over 500,000 records. The majority of those breaches were hacking incidents, many of which involved ransomware or attempted extortion.

It is clear that data breaches in healthcare will have a significant impact on the industry. Not only do these incidents put patients’ sensitive information at risk, but they also pose financial, legal, and reputational risks to healthcare organizations. Therefore, it is critical that healthcare organizations prioritize application security in order to mitigate the risks associated with data breaches and protect their patients’ confidential information.

Top 5 AppSec Trends in Healthcare for 2023

Adoption of Artificial Intelligence (AI) for AppSec in Healthcare

The adoption of Artificial Intelligence (AI) for AppSec is rapidly gaining traction in the healthcare industry. Thanks to its ability to automate threat detection and response, AI technologies are proving invaluable in augmenting security programs within the industry. As a result, more healthcare organizations are turning to AI tools to bolster their AppSec efforts, particularly as they strive to improve their compliance posture and protect patient data from emerging cyber threats. This trend is expected to accelerate, with even smaller healthcare entities embracing AI-powered AppSec solutions to better protect their systems and data from cyberattacks. With AI, healthcare organizations have a real opportunity to stay ahead of the curve in the constant battle against cybercrime, ensuring that the privacy and security of their patients’ data remains a top priority.

Implementation of Zero Trust Architecture for Healthcare Security

The implementation of Zero Trust Architecture provides a comprehensive security solution that enables healthcare providers to verify user identity and determine access privileges on a per-user basis, thereby limiting user access to only the required network resources. Consequently, the Zero Trust model is effective in curbing phishing attacks, ransomware attacks, and other sophisticated security breaches that pose a significant threat to healthcare organizations. By comprehensively enforcing access controls, this architecture model ensures that every access request is audited and authenticated for an extra layer of security.

Growing Significance of API Security in Healthcare

The healthcare industry has been a prime target for cyberattacks due to the vast amount of sensitive information it holds, including Personally Identifiable Information (PII), medical records, and financial information. APIs are now widely used in healthcare to share confidential patient data across different systems, making the security of APIs a critical concern. Healthcare organizations must prioritize API security by implementing robust security controls and regularly testing their APIs to detect vulnerabilities and protect against cyberattacks. We can expect the need for API security in healthcare to continue to grow in importance as cyber threats become more sophisticated.

Increased Use of Containerization for Secure Healthcare Applications

One of the significant challenges facing healthcare organizations is how to secure their applications in a rapidly evolving threat landscape. Containerization is an innovative approach for securing healthcare applications, involving the bundling of applications into containers that isolate them from the underlying system and make them more secure. It allows the delivery of isolated, sandboxed applications that can run anywhere, enabling secure and flexible cloud-based deployments, particularly in hybrid environments. As a result, containerization is becoming an increasingly popular method for securing healthcare applications. It should help healthcare organizations deploy more secure and scalable applications while reducing operational overheads, providing an additional level of security, and reducing the attack surface.

Advancement of DevSecOps for Enhanced Healthcare Application Security

DevSecOps is an approach that integrates security into every phase of the software development lifecycle, from design to deployment. In healthcare, it can help ensure that sensitive patient information is protected from vulnerabilities and cyber attacks. This trend is expected to gain momentum as healthcare organizations continue to prioritize data privacy and security. With the increasing use of connected medical devices and remote patient monitoring systems, healthcare apps must be designed and developed with security in mind. DevSecOps not only helps prevent security breaches but also enables faster and more efficient software delivery, making it an essential component of healthcare application development.

Conclusion

Healthcare organizations are now investing more in AppSec tools and methodologies to protect their sensitive data and meet regulatory compliance. The years ahead will see more advancements in AppSec technology such as the integration of AI and machine learning, increased use of automation, Zero Trust security architecture, and more. It is important that healthcare organizations remain up-to-date and vigilant regarding the latest AppSec trends to mitigate their security risks and better prepare themselves for future threats.
