biosdevname is an external tool that works with the udev framework for naming devices. biosdevname uses three methods to determine NIC names: 1. PCI firmware spec.3.1 2. smbios (matches # after em to OEM # printed on board or housing) 3. PCI IRQ Routing Table (uses # of NIC position in the device history). If the BIOS does not support biosdevname, noNICs are renamed. Rationale: biosdevname is an external tool that works with the udev framework for custom renaming of system hardware connections made by the kernel and BIOS. As allowing the renaming of devices can severely disrupt network communications by creating resource conflicts and provide an attack vector for denial of service exploits, this capability should be disabled or restricted according to the needs of the organization. Fix: Uninstall the biosdevname package: apt-get purge biosdevname

[yes/no]
