V-281289

Discussion

This requirement applies to wireless peripheral technologies (e.g., wireless mice, keyboards, displays, etc.) used with RHEL 10 systems. Wireless peripherals (e.g., Wi-Fi/Bluetooth/IR keyboards, mice and pointing devices, and near field communications [NFC]) present a unique challenge by creating an open, unsecured port on a computer. Wireless peripherals must meet DOD requirements for wireless data transmission and be approved for use by the authorizing official. Even though some wireless peripherals, such as mice and pointing devices, do not ordinarily carry information that must be protected, modification of communications with these wireless peripherals may be used to compromise the RHEL 10 operating system. Satisfies: SRG-OS-000095-GPOS-00049, SRG-OS-000300-GPOS-00118

Check Content

Verify RHEL 10 disables the ability to load the Bluetooth kernel module with the following command:

$ sudo grep -rs bluetooth /etc/modprobe.conf /etc/modprobe.d/*
/etc/modprobe.d/bluetooth.conf:install bluetooth /bin/false
/etc/modprobe.d/bluetooth.conf:blacklist bluetooth

If the command does not return any output, or the lines are commented out, and use of Bluetooth is not documented with the information system security officer as an operational requirement, this is a finding.
