A BIOMED technician notices that medical device telemetry data is dropping packets on the hospital Wi-Fi. Which QoS mechanism should be prioritized to ensure reliable transmission?
Answer: Weighted Fair Queuing (WFQ) with medical traffic class
Weighted Fair Queuing assigns higher priority to critical medical traffic classes, reducing dropped packets for telemetry.
Under HIPAA's Security Rule, which control specifically addresses ensuring that ePHI transmitted over a network cannot be improperly modified without detection?
Answer: Transmission integrity
Transmission integrity controls verify that ePHI is not altered or destroyed in an unauthorized manner during network transmission.
A hospital wants to segment its biomedical device network from the administrative network. Which technology accomplishes this at Layer 2?
Answer: VLAN (Virtual LAN)
VLANs logically segment networks at Layer 2 (Data Link), isolating biomedical device traffic from administrative systems.
Which encryption protocol is recommended by NIST for securing data transmitted between medical devices and hospital servers in 2024?
Answer: TLS 1.2 or higher
NIST recommends TLS 1.2 or TLS 1.3 for securing data in transit; older protocols like SSL 3.0 and WEP are deprecated.
A biomedical device is assigned a static IP of 192.168.10.50/24. What is the broadcast address for this subnet?
Answer: 192.168.10.255
For a /24 subnet, the broadcast address is the last address in the range — 192.168.10.255.
During a risk assessment of a networked infusion pump, the BIOMED technician identifies that the device uses Telnet for remote management. What is the primary security concern?
Answer: Telnet transmits data including credentials in plaintext
Telnet sends all data, including usernames and passwords, as unencrypted plaintext, making it vulnerable to eavesdropping.
A hospital's IDS generates an alert when a networked vital signs monitor begins scanning other IP addresses on the LAN. What type of attack does this behavior most likely indicate?
Answer: Lateral movement / network reconnaissance
Port/IP scanning from a compromised device indicates an attacker performing network reconnaissance to identify additional targets for lateral movement.
