Data security in healthcare has become increasingly important as the sector relies more heavily on digital tools to deliver results. By implementing strong data security measures, healthcare groups can continue to deliver effective care, maintain regulatory compliance, and protect their patients from malicious actors.
Data Security vs. Data Privacy vs. Cybersecurity
Given how similar they sound, there is some understandable confusion about the differences between data security, data privacy, and cybersecurity. While the three topics do intersect, they are distinct categories that require definition.
Data Security vs. Data Privacy
Data privacy focuses on keeping data confidential, while data security focuses on protecting it from malicious activity or sabotage. In other words, private data can still be corrupted or destroyed by malware; the contents of that data are still inaccessible for unauthorized parties, but that’s not much consolation for the data owners. The aim of data security is to prevent such destruction from happening.
Data Security vs. Cybersecurity
Data security is technically a subset of cybersecurity, which is the protection of computer systems, networks, and devices along with data. Data security is exclusively focused on protecting data’s confidentiality, integrity, and availability. Cybersecurity focuses on protecting the entire digital ecosystem.
Why Does Data Security in Healthcare Matter?
You may be asking, “Why go through all the trouble for data security? Does it really matter that much in healthcare?” The short answer is, yes, it absolutely does. The longer answer is that modern healthcare practices are absolutely reliant on data to deliver effective care. They are also obligated to protect their data as per stringent federal regulations.
Care Delivery and Documentation
Healthcare providers rely on digital records every day to deliver effective care to their patients. Electronic health records (EHRs) are the primary method for many groups when it comes to recording diagnoses, treatment plans, allergies, and more. Without this information, providers cannot determine what is wrong with a patient, the medication they’ve been prescribed, or who else has treated the patient. Data security measures are critical for ensuring reliable access.
Patient Privacy and HIPAA Compliance
Healthcare groups must also implement data security measures to protect their patients and maintain regulatory compliance. A patient’s health information is often deeply personal and could be used for a range of crimes if hackers were to access it. Social Security numbers, credit card information, addresses, and more are often included in a patient’s files, and all of them are ripe for abuse. Under the Health Insurance Portability and Accountability Act (HIPAA), personal health information is considered private and must be protected against unauthorized access. Companies that fail to maintain this compliance can face severe financial penalties and even prison time for extreme cases of negligence.
Threats to Data Security in Healthcare
Given the high value of private health information to cybercriminals, healthcare groups must be prepared for a wide range of threats.
- Accidental Exposure: Simple human error can lead to data being shared with the wrong group or individuals. This could include sending an email to the wrong address or losing a data storage device. Even leaving health information on an easily viewable screen can be considered a privacy violation.
- Phishing and Social Engineering: The most common type of cyberattack, phishing, involves tricking people into revealing private information such as passwords or login keys. Criminals can then use this information to compromise the entire network.
- SQL Injection: Standard Query Language requests are the standard form of communication in an application’s database. An SQL request includes a set of parameters that instruct the database on which records to retrieve. For example, a healthcare provider can search the database for every patient with a heart condition over the age of sixty who has an appointment scheduled for this month. An SQL injection adds malicious code to the query, which can also access or delete information in the database.
- Ransomware: Ransomware is a type of malware that infects devices and encrypts their stored data, making it useless without a matching decryption key. Attackers will then issue a ransom and demand payment for those decryption keys. If their demands aren’t met, the data remains encrypted and useless forever. If unchecked, ransomware can rapidly spread and infect an entire network, leaving organizations without their irreplaceable data.
Solutions and Best Practices
With the threat of cybercrimes targeting their data growing with each passing year, healthcare groups must take the right precautions. These are some of the most important techniques and best practices for healthcare groups to ensure data security.
- Access Control: The first step towards ensuring data security is controlling who can access it in the first place. This includes both physical and digital means of access control, such as RFID cards that only work with medical computers that can scan RFID tags and allow access. This ensures that only authorized personnel can access the facility’s network and data.
- Data Encryption: One of HIPAA’s most important requirements is that private health data remains encrypted when not being used. This means that the data has been converted from a readable format into an unreadable one, and can only be decrypted with the correct key. This means that even if criminals manage to access or steal the data, they cannot read or interact with it.
- Data Loss Prevention: Physical and digital redundancies are critical for protecting data in case it is damaged or destroyed. Storing data off-site or across multiple servers helps ensure that backups are available, even if a cyberattack or natural disaster destroys the primary copy.
- Incident Response: Incident response plans help prepare healthcare groups for when a data breach occurs. This means having a team of professionals with a wide range of skills, including IT, legal, PR, and more, equipped with the right tools. This lets them detect, analyze, contain, and destroy data intrusions and communicate with other stakeholders throughout the process.
- Vulnerability Assessments: The best way to find vulnerabilities in a system is to put it through a simulated attack. This often takes the form of “whitehat” hackers looking for weaknesses, response drills that test how employees react to a data outage or phishing attempt, and consulting with third-party specialists.
