Armis Centrix™ for Medical Device Security

Our approach is “patient-centric” because every aspect of our platform is designed to protect the patient journey and ensure the continuity of care.

• Holistic Coverage: We secure every technology asset a patient might interact with, from check-in kiosks to bedside monitors and surgical equipment.
• Risk Prioritization for Patient Safety: We believe the biggest risks are those that threaten patient safety. Our platform is built to identify and mitigate these risks above all else.
• Ensuring Operational Continuity: By preventing cyberattacks and reducing downtime, we help ensure that healthcare providers can deliver life-saving care without interruption.

Healthcare teams are often overwhelmed with thousands of alerts. Armis Centrix™ cuts through the noise by helping you focus on the vulnerabilities that pose the greatest risk to patient care.

Instead of just relying on a technical severity score (CVSS), Armis prioritizes vulnerabilities based on the actual risk to your organization, considering:

• Asset Criticality: Is this device a patient monitor in the ICU or a printer in the back office?
• Clinical Risk Score: How would a compromise of this device impact patient safety and care delivery?
• Automated Workflows: We automatically assign owners and initiate remediation workflows so your teams can act faster on the biggest threats.

Armis Centrix™ provides valuable operational insights that help clinical engineering and IT teams work together to manage device fleets more effectively.

You can:

• Optimize Device Allocation: See high and low usage data to ensure expensive equipment like infusion pumps are where they are needed most.
• Improve Patient Flow: Track device usage patterns to identify and resolve bottlenecks in patient care.
• Pinpoint Physical Location: Find assets quickly to streamline maintenance, manage recalls, or perform site-based risk analysis.
• Maximize Investments: Use data to make informed decisions about procurement and extend the lifespan of your existing medical devices.

Armis Centrix™ enables you to implement smart network segmentation and microsegmentation policies to contain threats without disrupting clinical operations.

• Policy Based on Identity, Not Just IP: We go beyond basic IP addresses to enable microsegmentation based on each asset’s identity, behavior, role, and risk level.
• Dynamic Enforcement: Policies are enforced in real-time. If a device exhibits abnormal behavior, its network access can be automatically restricted.
• Works With Your Existing Infrastructure: Armis integrates seamlessly with your existing firewalls, switches, and NACs to enforce these policies, eliminating the need for a costly infrastructure overhaul.

Asset behavior monitoring allows you to spot the earliest signs of a compromise. Instead of reacting to an attack after it happens, you can be proactive.

The key benefits are:

• Establish a Baseline: Armis learns the “known good” behavior for every device on your network.
• Detect Anomalies: You get immediate alerts when a device deviates from its normal behavior, such as communicating with a suspicious server.
• Enable Proactive Response: This early warning allows your teams to investigate and mitigate potential threats before they escalate into a full-blown incident.

Armis Centrix™ helps you get ahead of ransomware by shifting your security posture from reactive to proactive. Here’s how:

• Proactive Threat Intelligence: We provide real-time intelligence on the latest attacker tactics and zero-day vulnerabilities, helping you secure devices before they are exploited.
• Risk-Based Prioritization: We help you focus on fixing the most critical threats first, based on their potential impact on your operations.
• Automated Containment: Armis can automatically enforce policies to quarantine a suspicious device or remove its network access, stopping a potential ransomware attack from spreading.

Armis Centrix™ discovers and classifies every asset without needing to install any software agents. Our unique multi-detection engine combines three key methods:

• Integrations: We use hundreds of pre-built integrations with your existing IT and security tools (like network switches, firewalls, and endpoint solutions) to build a complete inventory from day one.
• Network Traffic Analysis: Armis passively and safely monitors network traffic to identify devices and analyze their behavior, ensuring no disruption to sensitive clinical assets.
• The Asset Intelligence Engine: Our crowdsourced, cloud-based database of over 6.5 billion assets compares your devices against a global library to instantly identify them and flag known risks.

Healthcare organizations face a “perfect storm” of security challenges, including:

• Device Diversity: A single hospital uses thousands of different devices from hundreds of manufacturers, each with its own security protocols.
• Pervasive Vulnerabilities: An estimated 53% of medical devices have known, unpatched vulnerabilities that attackers actively exploit.
• Massive Scale: The average hospital has over 17 connected devices per bed, many of which are unmanaged and unmonitored by traditional IT security tools.
• Expanding Attack Surface: Over 90% of cyberattacks begin with IoT devices. Security must cover the entire technology ecosystem, not just medical devices.

WATCH OUR ON-DEMAND WEBINAR

Medical devices present a unique and critical security challenge. Proactive cybersecurity is essential because many devices are:

• Legacy Devices: Often, devices are several years old and run on outdated operating systems that can’t be easily patched.
• Difficult to Update: Taking a critical device like an MRI or CT scanner offline for patching can disrupt patient care and is often not feasible.
• Directly Tied to Patient Care: A compromised medical device can have immediate and severe consequences for patient safety and treatment outcomes.

SEE THE PLATFORM IN ACTION

Internet of Medical Things (IoMT) refers to medical devices and applications with Internet connectivity. It’s a subset of Internet of Things (IoT) and, for this reason, is often referred to as IoT in healthcare.

The overall category of IoT devices is typically more consumer-oriented, focusing on usability and convenience. IoT devices include smart TVs, lighting apps, voice assistants—really any number of smart, connected devices. IoMT devices and applications are designed with healthcare in mind, including:

• Smart thermometers and infusion pumps
• Remote patient monitoring (R\PM) devices
• Personal emergency response systems (PERS)
• Heart rate sensors and glucose monitors
• Ingestible sensors and cameras
• MRI machines

Connected medical devices help healthcare workers deliver faster and better care. Use cases range from robotic surgery to glucose monitoring. Benefits of IoMT include:

• Improved treatments and cost savings
• Faster and precise diagnostics, as IoMT technology can track patient’s vital signs in-depth and detail
• Better patient monitoring, without requiring visits to a medical facility

The proliferation of connected devices in hospitals and medical facilities expands these organizations’ attack surface. Medical data privacy is also a concern and subject to regulations, such as the Health Insurance Portability and Accountability Act (HIPAA).

In addition, IoMT devices have unique cybersecurity challenges. For example:

• IoMT devices are often not built with security in mind and lack inherent controls. And many of those devices in use are based on old and vulnerable software and cannot be easily updated or patched.
• Traditional IT security tools can’t see or secure IoMT assets because the devices cannot accommodate endpoint agents. Scans are disruptive and can cause IoMT systems to crash.
• Device certification requirements complicate the patching process, leading to vulnerability and exposure to cyberattacks.

Limited correlation of security vulnerabilities with safety impact potentially causes issues with prioritization of information security response and recovery workflows.

Often referred to as Internet of Medical Things (IoMT), IoT in healthcare refers to the use of IoT technology in the delivery of patient care. This includes the use of connected devices, sensors, and systems to collect and transmit data for various purposes, such as monitoring patients’ health, improving medical treatments, and streamlining healthcare processes.

Examples of applications of IoT in the healthcare industry include wearable devices (such as heart rate sensors), connected medical equipment (such as smart infusion pumps), and patient communication and engagement (tablet devices). IoT devices — along with operational technology (OT), such as HVAC and other building management systems — contribute to the expanding attack surface in healthcare
