Venue 50 Security (continued)
We have worked diligently to develop a combination of the
safety measures above and the native security advantage of
Venue 50 to provide a degree of safety against Viruses, Worms,
Trojan Horses, etc., especially for a system used in a
professional hospital grade networking environment that also
typically features its own sufficient safety measures.
Finally, a few points as to why we do not use Anti-Virus software.
The main reasons for not doing so:
• Customized OS of Venue 50 is natively immune to most
viruses. Only few viruses can run on Venue 50 system.
• Every Virus scanner is constantly active in the background.
Due to the software-intensive operating system of the
Ultrasound scanner, all computing resources are required
for normal operation of this device. Anti-Virus software
activities would have a negative impact on the system
performance.
• The operating software of a medical Ultrasound system is
part of an FDA-cleared medical device that requires a
specific release process. Any update of the Anti-Virus
software would mean a change of the system software.
Such change would require an extensive release and
validation process to help ensure that the Anti-Virus update
does not have any impact on the system software
performance and stability.
