Identity and Access Management (IAM)
Implementing a robust IAM system in the cloud environment is critical for controlling who can access patient records and what actions they can perform. This includes using strong passwords, multi-factor authentication (MFA), role-based access control (RBAC), and regular access reviews. MFA adds an extra layer of security by requiring users to provide multiple forms of identification before granting access. RBAC ensures that users are only granted the necessary permissions based on their roles and responsibilities, minimizing the risk of unauthorized access or data breaches.
-
Network Security and Firewalls
Securing the network perimeter and internal network segments in the cloud environment is essential. This involves configuring firewalls, intrusion detection and prevention systems (IDPS), and virtual private networks (VPNs) to control network traffic and prevent unauthorized access. Cloud providers offer various network security tools and services that can be configured to meet the specific security requirements of healthcare organizations. It’s crucial to work with cloud migration services that have expertise in configuring these security controls effectively.
