Enhancing Cybersecurity in the Healthcare Sector: Best Practices
The severity of a successful cyber-attack on a healthcare institution doesn’t just stop at theft of personal information and financial losses: it can affect people’s health and lives. Ardent Health Services, which operates 30 hospitals across six U.S. states, suffered a ransomware attack in late November 2023 that shut down emergency rooms in at least three states and took its network offline, forcing the transfer of some patients to other hospitals.
It should be clear that healthcare institutions must prioritize cybersecurity measures to protect their sensitive data, critical systems, and most importantly, their patients.
Understanding the risks is the first step to better preparation and protection against cyber threats, but that’s only the beginning. Implementing cybersecurity best practices and strategies to mitigate these risks and ensure the integrity and confidentiality of systems and patient information is an ongoing process that cannot be overlooked.
This article aims to shed light on the crucial role of cybersecurity in the healthcare sector, exploring the challenges, solutions, and strategies to protect patient information and healthcare systems from cyber threats.
Cyber Threats Targeting Healthcare
These breaches can lead to the unauthorized access and theft of patient records, financial information, and other sensitive data. HCA Healthcare suffered a major breach in July 2023 that exposed the information of 11 million patients – one of the biggest healthcare breaches in history.
Here, attackers lock healthcare providers out of their own systems and demand payment to restore access. This kind of attack jeopardizes patient data and can disrupt critical healthcare operations, potentially putting lives at risk – as Ardent Health Services unfortunately discovered.
HIPAA Journal reports that phishing is the leading cause of data breaches in the healthcare sector. Cybercriminals trick employees into revealing sensitive information or downloading malware. These attacks often begin with seemingly innocuous emails that, upon closer inspection, contain malicious links or attachments.
7 Healthcare Cybersecurity Best Practices
Encrypting patient data is like adding a secure vault around information. It ensures that even if data is accessed without authorization, it remains unreadable and useless to the intruder. Encryption should be a standard for both stored data and data in transit.
Keeping software up-to-date patches vulnerabilities before they can be exploited. Automated patch management tools help to streamline this process, updating the software as soon as vendors release the patch.
Staff members are often the first line of defense against cyber threats. Regular training sessions should be conducted to keep them aware of the latest social engineering tactics and best practices for maintaining cyber awareness. Empowering employees with this knowledge is a critical step in preventing inadvertent breaches.
Implementing stringent access controls ensures that only authorized personnel can access sensitive data. This can be achieved through methods like role-based access, which grants access only to the information necessary for their job functions.
Endpoint protection solutions can detect and block threats at devices connected to the network, preventing them from spreading. Given the multitude of devices used in healthcare settings, protecting these endpoints is crucial.
Data Loss Prevention (DLP)
DLP solutions are essential in monitoring and controlling the data that moves across the healthcare network. These tools can identify sensitive data and enforce policies that prevent unauthorized access or sharing, thereby reducing the risk of accidental or malicious data breaches.
Regularly backing up data ensures that, in the event of a cyber incident, healthcare providers can restore their data and maintain continuity of care. These backups should be conducted frequently and tested regularly to ensure data can be effectively restored when needed.
Steps to Implement a Cybersecurity Framework
Creating a resilient cybersecurity framework serves as a blueprint for identifying, managing, and mitigating cyber risks effectively.
1. Develop Framework
Start by assessing the unique needs and vulnerabilities of your healthcare institution. This involves identifying critical assets, evaluating potential threats, and understanding the impact of different types of cyber incidents.
2. Risk Assessment
Conduct thorough risk assessments to pinpoint weaknesses in your system. This includes analyzing the likelihood of different types of cyber-attacks and the potential impact they could have on operations and patient safety.
Based on the risk assessment, develop tailored strategies to mitigate identified risks. This could involve strengthening network security, creating employee cyber awareness programs, or implementing advanced security solutions.
4. Develop Policies
Establish clear policies and procedures for cybersecurity. This includes guidelines for handling sensitive patient data, protocols for responding to security incidents, and procedures for regular security audits.
5. Ongoing Monitoring
Cyber threats evolve constantly, necessitating ongoing monitoring of your cybersecurity framework. Regularly review and update your strategies and practices to address new and emerging threats.
