Common Cloud Security Risks and Solutions for Healthcare Organizations
Common Cloud Security Risks in Healthcare
Healthcare organizations face a unique set of challenges when it comes to cloud security. These risks not only threaten sensitive patient data but also jeopardize regulatory compliance and clinical operations. Recognizing these vulnerabilities is crucial for creating cloud environments that safeguard both patients and providers. Below are some of the most pressing security risks in healthcare cloud systems.
Misconfigurations and Insecure Cloud Architectures
Cloud misconfigurations are a major issue for healthcare systems. According to the 2024 CSA report, they rank as one of the most frequent causes of ePHI (electronic Protected Health Information) exposure and compliance violations [2]. Common mistakes include leaving S3 buckets open with unencrypted data, allowing overly permissive access, failing to change default settings, and using weak network security groups. These errors make healthcare organizations a prime target for attackers.
In 2022, 61% of healthcare respondents reported experiencing a cloud infrastructure breach. Many of these breaches were tied to misconfigurations, especially during cloud migrations when storage solutions were improperly set up [4]. Attackers actively search for vulnerabilities like open buckets and weak access controls, exploiting them to access patient records, trigger HIPAA violations, and impose hefty fines.
Weak Identity and Access Management
Failures in Identity and Access Management (IAM) create easy opportunities for unauthorized access to sensitive healthcare data. Many healthcare organizations still rely on single-factor authentication, grant excessive user privileges, share accounts, and lack robust measures like multi-factor authentication (MFA) or timely credential revocation [2].
The numbers are alarming: over 90% of healthcare cyberattacks involve phishing schemes aimed at stealing credentials [2]. Once attackers gain access, weak IAM practices often allow them to move freely within systems, exposing electronic health records and other protected health information. These vulnerabilities also open the door to risks associated with third-party integrations and APIs.
Third-Party and API Risks
The interconnected nature of healthcare systems significantly expands the attack surface. On average, healthcare organizations work with 15.5 third-party vendors, and 98.3% reported breaches involving their partners in 2023 [2]. This reliance on external vendors handling sensitive data creates numerous entry points for attackers.
Insecure APIs and inadequate vendor assessments further complicate the situation. Third-party and supply-chain breaches are now the second most common cause of data compromises, trailing only ransomware attacks [2]. Unfortunately, traditional risk assessments - often based on lengthy questionnaires and spreadsheets - struggle to keep up with the rapidly changing cybersecurity landscape.
Ransomware and Backup Vulnerabilities
Ransomware attacks have adapted to target cloud-based workloads and backup systems in healthcare. Attackers understand that healthcare providers rely on uninterrupted access to patient data, making them more likely to pay ransoms when systems are locked down. The risk is compounded by improper backup configurations, such as storing backups in the same environment as production systems, infrequent backup schedules, or the lack of offline backup copies.
The fallout from a ransomware attack can be severe. Clinical systems may go offline, delaying patient care and forcing providers to revert to paper-based processes. These vulnerabilities are further amplified during transitions from legacy systems to cloud platforms, where inconsistent protocols and scattered data storage create additional risks [5].
Data Privacy and Monitoring Gaps
A lack of visibility into cloud environments creates exploitable blind spots for attackers. Common issues include poor logging practices, the absence of real-time monitoring, and difficulties with data residency and cross-border transfers. A systematic review identified confidentiality, data security, availability, integrity, and network security as the top challenges in healthcare cloud systems [3].
Without continuous monitoring, suspicious activities often go unnoticed until after a breach has occurred. Many healthcare organizations lack the tools needed to detect configuration changes, unauthorized access attempts, or data exfiltration in real time. This lack of visibility also makes it harder to reassess risks for critical components like APIs and containers, leaving systems vulnerable to evolving threats.
Solutions to Mitigate Cloud Security Risks
Healthcare organizations face a growing need to address vulnerabilities in cloud environments. Moving from reactive to proactive strategies is essential for protecting sensitive data and staying compliant with regulations. Here’s how organizations can strengthen their security measures while aligning with industry best practices.
Improving Cloud Configurations and Architecture
Using Cloud Security Posture Management (CSPM) tools is a smart way to catch misconfigurations like open S3 buckets, permissive access controls, or weak security groups before they lead to breaches. These tools conduct automated scans and provide recommendations, cutting down on manual tasks for security teams - a crucial step, as highlighted in the 2024 CSA report [2].
Encryption and network design are also critical. Employ AES-256 and TLS 1.3 for data encryption, and manage encryption keys securely with tools like AWS KMS. Adopting a zero-trust approach with features like micro-segmentation, VPCs, and security groups can help isolate sensitive data like Protected Health Information (PHI). Regular integrity checks, anti-malware scanning, and vulnerability assessments - along with quarterly penetration tests - help identify issues early. Automated monitoring tools can also flag risks tied to new APIs or containers, enabling teams to act swiftly.
Strengthening Identity and Access Controls
Tight identity management is non-negotiable. Require multi-factor authentication (MFA) for all accounts, using hardware tokens or authenticator apps for added security. Implement role-based access control (RBAC) to ensure users only have access to the data they need. For instance, clinicians might be limited to read-only access for specific patient records, ensuring sensitive information remains secure [2].
Given that over 80% of healthcare organizations reported phishing attacks in 2024, continuous monitoring of identity events is crucial [2]. Tools like AWS CloudTrail or Azure Sentinel can track login attempts, privilege escalations, and failed authentications in real time. They also alert teams to suspicious activity, such as logins from unfamiliar IP addresses or access during unusual hours. Promptly deactivating credentials for former employees further reduces risks.
Managing Third-Party and API Risks
Traditional vendor risk assessments, often reliant on spreadsheets and questionnaires, are too slow to keep up with modern threats. Instead, healthcare organizations should consider cloud-based risk exchange platforms designed for the industry's specific needs. These platforms enable faster, more secure sharing of cybersecurity data between healthcare providers and their vendors, streamlining risk assessments [1].
For example, Tower Health’s CISO, Terry Grogan, shared how adopting Censinet RiskOps significantly improved efficiency while reducing staffing needs [1]. This shift is especially important given that healthcare organizations work with an average of 15.5 third-party vendors, and nearly all (98.3%) experienced at least one vendor-related breach in 2023 [2].
Continuous vendor monitoring is key. Instead of relying solely on annual reviews, organizations can use platforms offering ongoing risk visibility. Including specific security requirements in vendor contracts and applying secure API practices - such as strong authentication, rate limiting, and frequent security testing - can further safeguard patient data.
Improving Backup and Recovery Strategies
A solid backup and recovery plan is essential for mitigating ransomware threats. Immutable backups prevent attackers from altering or deleting stored data, ensuring critical information remains safe even during an attack [2]. These backups should be stored separately from production systems, with offline copies kept for added security.
Encryption is a must for backup data, and disaster recovery procedures should be tested quarterly. Regular testing ensures systems can be restored quickly and confirms the integrity of backup data, aligning with the NIST Cybersecurity Framework [2].
Closing Monitoring and Compliance Gaps
Centralized logging through Security Information and Event Management (SIEM) tools like Splunk or the ELK Stack provides real-time insights into configuration changes, unauthorized access, and potential data breaches [2]. Aligning cloud security controls with frameworks like HIPAA, HHS 405(d), and NIST ensures compliance with regulatory requirements.
To maintain focus on cloud security, organizations can establish a dedicated cloud risk committee. Quarterly reviews, clear accountability for security responsibilities, and regular reporting on risk metrics to leadership can help keep cloud security a strategic priority. Documented policies and consistent oversight ensure that no gaps go unnoticed.
