NETWORK COMMUNICATION

WIRELESS

Wireless switching prevents the network from being connected at the hardware level. Once the link is detected on the wired network adapter, the wireless adapter is automatically disabled.

This feature is an excellent measure to:

• Prevent unauthorized network bridging: network bridging is a technique used to bypass security controls by establishing a connection between two different networks. Disabling wireless connectivity can prevent users from establishing unauthorized network bridges by automatically disabling the wireless connection when the wired connection is detected.

• Limiting the risk of network security compromise by preventing users from establishing unauthorized network bridges, disabling wireless connectivity can help limit the risk of network security compromise by preventing potential attackers from accessing sensitive data or launching man-in-the-middle attacks from their own machine.

Therefore, it is recommended to:

• Enable this option.

NETWORK INTERFACE CONTROLLER (NIC)

In the BIOSes of Dell computers, the "Integrated NIC" feature allows you to control the settings of the integrated network card. For example, you can enable or disable the network card, configure speed and duplex settings (e.g. 10/100/1000 Mbps), or configure advanced settings such as VLAN support or Wake-on-LAN.

Therefore, it is recommended to:

• Enable this option only if the workstation is to use the built-in network card,

  • Disable PXE boot if not needed

  • Enable PXE boot if used

    • Enable the protections available with UEFI on this protocol
