Legal Notice
All information products included in https://us-cert.cisa.gov/ics are provided "as is" for informational purposes only. The Department of Homeland Security (DHS) does not provide any warranties of any kind regarding any information contained within. DHS does not endorse any commercial product or service, referenced in this product or otherwise.

Risk evaluation
Successful exploitation of these vulnerabilities may allow an attacker unauthorized access to data (including patient data) and create a denial of service resulting in temporary interruption of viewing physiological data at the central station. Exploitation does not enable modification or change to point-of-care devices.
Critical infrastructure sectors
Healthcare and Public Health
Countries/areas deployed
Worldwide
Company headquarters location
Netherlands
Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should: Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet; Locate control system networks and remote devices behind firewalls and isolate them from the business network; When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as its connected devices.
Recommended Practices
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage onus-cert.cisa.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Recommended Practices
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage on us-cert.cisa.gov in the Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
Exploitability
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely.
