Electronic health records (EHRs)
The use of electronic health records (EHRs) has significantly increased over the past decade. EHRs contain sensitive patient information, such as names and addresses, tests, diagnoses, treatment plans, and medical history. While EHRs offer many advantages, such as improved efficiency, cost reduction, and enhanced healthcare quality, they also face potential security risks that may compromise the confidentiality and privacy of patient data.
To address these concerns, researchers have conducted literature reviews and analyzed security techniques for EHRs. These studies explore the perceived vulnerabilities of EHRs, common security issues, and strategies to enhance data protection. Academic journals and credible databases, including PubMed, CINAHL, and ProQuest, have been utilized to gather relevant information. The United States, for instance, has transitioned from paper to electronic health records, necessitating a focus on security measures.
The Health Insurance Portability and Accountability Act (HIPAA) plays a crucial role in protecting electronic patient health information. It establishes a national set of security standards to safeguard identifiable health data. However, despite the implementation of HIPAA-compliant security measures, data breaches still occur, resulting in significant financial costs for the healthcare industry. Therefore, it is essential to continually explore and strengthen security strategies for EHRs.
Healthcare organizations must identify effective approaches to secure EHRs and prevent unauthorized access. Strategies such as privacy-protection awareness and staff training can enhance the security of health records databases. Additionally, companies like CloudWave offer data security services within the healthcare sector, providing system integration, management, and protection tailored to the specific needs of healthcare organizations using EHR services.
Furthermore, with the increasing prevalence of connected medical devices and the Internet of Things (IoT), specialized security solutions like Cynerio and Cylera focus on managing these unique security challenges. These solutions empower healthcare CISOs with comprehensive control over their clinical engineering and IoT ecosystems, ensuring data protection, service continuity, and patient safety. By adopting such advanced security measures, healthcare providers can better protect patient privacy and maintain the integrity of EHRs.

Health Insurance Portability and Accountability Act (HIPAA)
The Health Insurance Portability and Accountability Act (HIPAA) of 1996 establishes federal standards to protect sensitive health information from disclosure without a patient's consent. The US Department of Health and Human Services (HHS) issued the HIPAA Privacy Rule to implement HIPAA requirements, with the HHS Office for Civil Rights enforcing HIPAA rules. The Privacy Rule standards address the use and disclosure of individuals' protected health information (PHI) by covered entities, which include health plans, health care clearinghouses, and health care providers conducting standard health care transactions electronically. The Privacy Rule also contains standards for individuals' rights to understand and control how their health information is used.
To comply with the HIPAA Security Rule, covered entities must ensure the confidentiality, integrity, and availability of all electronic PHI (e-PHI). This includes detecting and safeguarding against anticipated threats to the security of the information and protecting against impermissible uses or disclosures not allowed by the rule. The Security Rule establishes a national set of security standards to protect health information maintained or transmitted in electronic form. Regulated entities must implement policies and procedures to specify the proper use of, and physical safeguards for, workstations that can access e-PHI. This includes device and media controls, such as governing the receipt and removal of hardware and electronic media containing e-PHI, as well as access control measures to allow only authorized persons to access e-PHI.
HIPAA also includes Administrative Simplification provisions that required HHS to adopt national standards for electronic health care transactions and code sets, unique health identifiers, and security. Congress recognized that advances in electronic technology could erode the privacy of health information, so they incorporated provisions into HIPAA that mandated the adoption of Federal privacy protections for individually identifiable health information. HHS published a final Privacy Rule in December 2000, later modified in August 2002 and in 2013, setting national standards for the protection of individually identifiable health information.
HIPAA violations may result in civil monetary or criminal penalties. The Secretary of HHS is responsible for reviewing and modifying the standards adopted under HIPAA, but no more frequently than once every 12 months.

Cybersecurity threats and solutions
Hospitals have become increasingly reliant on electronic devices and connected technologies, from computers and smartphones to medical devices that monitor vital signs, administer medications, and support breathing and blood circulation. This growing connectivity has exposed hospitals to new cybersecurity vulnerabilities and made them a prime target for cybercriminals.
In 2015, the healthcare industry was the most attacked sector by cybercriminals, according to IBM's Cyber Security Intelligence Index. Data breaches in healthcare have led to significant financial losses, costing up to $6.2 billion. Additionally, hospitals face the threat of ransomware attacks, where critical systems are locked, and patient data is held hostage until a ransom is paid. These attacks have disrupted operations, caused costly downtime, and even led to delayed diagnoses and, in extreme cases, patient deaths.
To address these cybersecurity threats, hospitals must implement robust cybersecurity solutions. This includes utilizing firewalls, encryption, and endpoint protection to secure their systems. Hospitals should also prioritize tools with real-time threat detection and conduct regular audits to ensure compliance with regulatory standards, such as HIPAA in the US.
Additionally, hospitals should leverage healthcare IT consulting services to perform risk assessments and develop tailored security plans. Training staff is also crucial; employees should be educated about phishing and other cybersecurity threats to build a human firewall that can recognize and mitigate suspicious activity.
There are also companies that provide specialized services in this area. For example, CloudWave offers the Sensato Cybersecurity suite, which provides hospitals with a simple solution to implement a fully managed cybersecurity program. Cynerio, another company in this space, focuses on managing the security challenges posed by the increasing number of connected medical devices within hospital networks. Their system gives healthcare security teams comprehensive control over their connected devices and helps them understand and mitigate associated risks.

Policies and Procedures
Regulated entities, such as hospitals, must implement comprehensive policies and procedures for workstations that can access electronic Protected Health Information (ePHI). These policies should outline the proper use and physical safeguards for workstations to ensure the protection of sensitive patient information. This includes addressing the integrity, confidentiality, and availability of information.
Access Control
Implementing technical policies and procedures to restrict access to authorized personnel is essential. Hospitals should utilize access controls, such as passwords, two-factor authentication, and role-based access controls, to ensure that only authorized individuals can view and modify patient information. This helps prevent unauthorized access and potential data breaches.
Device and Media Controls
Hospitals must establish procedures for the receipt, removal, and movement of hardware and electronic media containing ePHI within their facilities. This includes governing the final disposition of ePHI and the secure disposal or reuse of storage media. Clear and strict protocols ensure that patient data is handled securely at all times, reducing the risk of data breaches and unauthorized access.
Cybersecurity Measures
With medical devices increasingly connected to the internet and hospital networks, hospitals must work closely with manufacturers and cybersecurity experts to manage cybersecurity risks. This includes implementing solutions like the Sensato Cybersecurity suite, offered by CloudWave, which helps detect threats and respond to incidents. Additionally, hospitals should consider participating in initiatives like the Medical Device and Health IT Joint Security Plan (JSP), a guide to developing and deploying cybersecure technology solutions.
Compliance and Auditing
Hospitals must periodically assess their compliance with security standards and regulations, such as those outlined in the Health Insurance Portability and Accountability Act (HIPAA). This includes evaluating the effectiveness of their security safeguards and identifying areas where improvements can be made. Audit trail programs are also valuable tools, enabling hospitals to monitor access to patient information, track modifications, and flag suspicious activities, ensuring accountability and deterring unauthorized access.

Audit trails
The HIPAA Security Rule includes a provision on Audit Controls, mandating that "Covered Entities and Business Associates implement hardware, software, and/or procedural mechanisms that record and examine activity in information systems that contain or use ePHI." This means that healthcare organisations must maintain clear audit logs and trails to monitor the use and integrity of any system through which ePHI is transmitted or stored.
A system audit trail typically includes log-on credentials, attempts, timestamps, devices used for log-on, IP addresses, and whether the devices were inside or outside the organisation's firewall. User audit trails capture identifying information about users, log-on events, authentication attempts, and password updates. Application audit trails record user activities within each application, including when files containing ePHI are accessed, created, revised, or deleted.
By regularly reviewing these audit trails, organisations can identify anomalies and potential security breaches, detect internal fraud, and ensure compliance with privacy and security regulations.
In practice, healthcare institutions have varying levels of success in implementing comprehensive audit trails. A study of eight Portuguese hospitals found that while most hospitals collected audit trails from systems like the Electronic Patient Record (EPR), Radiology Information System (RIS), and Picture Archiving and Communication System (PACS), the quality of these audit trails was often lacking, with incomplete data fields and missing values. This highlights the importance of standardisation and completeness in audit trail structures to ensure their effectiveness in maintaining information security and compliance.
