While EMR systems are not currently the most targeted source of data by attackers, a data breach involving these EMR systems is of particular concern due to the range and sensitivity of data contained within them. Insider threat: malicious or unauthorized access to protected dataĮxternal attackers attempting to breach EMR systems are typically motivated by financial gain, either by stealing and selling sensitive data, incapacitating critical systems with ransomware, or increasingly both.External attackers: Attempts to access protected data in EMR or impact availability (i.e., ransomware).We will focus on two scenarios that can be monitored by Azure Sentinel that allow hospital security teams to detect and respond to threats, while accommodating some of the unique constraints that apply to most EMR implementations. However, this architecture remains equally applicable for organizations with non-Microsoft security controls. This architecture is built leveraging Azure and M365 components. Microsoft 365 Defender security controls, including Defender for Endpoint, Cloud App Security, Defender for Identity, Defender for Office 365 (recommended EMS E5 license bundle).On-premise BlueVoyant Managed Syslog Collector for network infrastructure logs.Log Analytics Agent/Azure Monitor Agent (AMA).Key solution components in-scope for this scenario include: The detection and response architecture for EPIC EMR environments including in-scope controls are based on BlueVoyant’s “Modern SOC,” using Azure Sentinel and Microsoft XDR tools. Security Monitoring for EPIC EMR with Azure Sentinel SIEM Detection and Response architecture A data breach can incur substantial fines, and more important, impact patient outcomes. The sensitivity of the data contained in EMR systems, generally protected under regulatory regimes for Personal Health Information (PHI), is an important factor. In this blog, we look at using Azure Sentinel and Microsoft XDR technologies to provide effective threat detection and response for EPIC Electronic Medical Record (EMR) environments.ĬISOs responsible for securing EMR systems have traditionally had a challenging task applying operational monitoring and security controls to these systems for a variety of reasons.Ĭontractual requirements in EMR vendor agreements and strict change control procedures often require normal IT Security functions like vulnerability management, patch management, access control, and threat hunting to make alternative arrangements or apply compensating controls.
