4. MITIGATIONS
BD recommends the following mitigations to reduce risk associated with this
vulnerability:
o Ensure physical access controls are in place to ensure only authorized
users have access to the affected product.
o Ensure only BD-approved equipment is connected to the RS-232 interface of
the affected pumps.
o When the affected pumps are delivering infusions, ensure no equipment is
connected to the RS-232 interface.
o Protect connected computer systems with BodyComm software with standard
security measures.

and ensure they are not accessible from the Internet .
o Locate control system networks and remote devices behind firewalls and
isolate them from business networks.
o 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.
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 at cisa.gov/ics . Several CISA products detailing cyber
defense best practices are available for reading and download, including
