Patch Management for Small Healthcare Organizations

Historical analysis: this article examines information published by the source on September 16, 2022. Check the latest vendor guidance before acting.

What was published

In September 2022, guidance was released detailing the implementation of patching processes specifically tailored for small healthcare organizations. The material defines patching as the regular application of security updates provided by software or device manufacturers to remove vulnerabilities.

Status and scope

This guidance is intended for small-scale healthcare entities. Its primary objective is to reduce the risk of ransomware, intentional or accidental data loss, and attacks targeting connected medical devices that could impact patient safety.

What the guidance covers

The guidance outlines several operational components for a patching program:

• Frequency and Validation: It suggests implementing vendor-produced patches at least monthly and validating that these updates were successfully applied.
• Prioritization: For vulnerabilities that cannot be resolved via standard patching, it recommends classification and prioritization. The Common Vulnerability Scoring System (CVSS) from the National Vulnerability Database (NVD) is cited as a standard for ranking severity to help organizations address the most severe issues first.
• Legacy Systems: It addresses end-of-life (EOL) software and operating systems, noting that these cannot be patched. The guidance suggests identifying these systems and either decommissioning them or returning them to a supported state.
• Medical Device Specifics: Patching for medical devices must rely on supported security patches released by the device manufacturers. The process involves IT operations collecting patches, performing regression tests to prevent negative business impacts, and scheduling implementation during routine change windows.

How organizations can use it

Healthcare providers can utilize this framework to move from ad-hoc updates to a structured cadence. By integrating CVSS rankings into their workflow, security leaders can align patching efforts with the organization’s specific risk tolerance. Clinical engineering and IT teams can use the suggested regression testing workflow to ensure that medical device updates do not interfere with clinical functionality before they are deployed in patient-care environments.

Decisions and next steps

Organizations evaluating this guidance should consider the following decision points:

1. Inventory Audit: Identify all current software and operating systems to determine which are end-of-life and cannot be patched.
2. Workflow Integration: Determine if existing change management windows can accommodate a monthly patching cycle without disrupting patient care.
3. Medical Device Coordination: Establish a formal communication channel between IT operations and clinical engineering to manage the collection and testing of manufacturer-supported device patches.

Verification of effectiveness can be achieved by auditing patch logs against vendor release dates and confirming that EOL systems have been removed or upgraded.

Limits and open questions

The guidance focuses on the application of available patches but does not provide a methodology for managing vulnerabilities where no patch exists, other than suggesting configuration changes or version upgrades. Additionally, while it recommends monthly updates, it does not address the challenges of patching critical systems that require 24/7 availability. Organizations should note that applying patches reduces the attack surface but does not eliminate all cybersecurity risks.
