Description
Without protection of communications with wireless peripherals, confidentiality and integrity may be compromised because unprotected communications can be intercepted and either read, altered, or used to compromise SLEM 5. This requirement applies to wireless peripheral technologies (e.g., wireless mice, keyboards, displays, etc.) used with a SLEM 5. Wireless peripherals (e.g., Wi-Fi/Bluetooth/IR keyboards, mice, 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 AO. Even though some wireless peripherals, such as mice and pointing devices, do not ordinarily carry information that need to be protected, modification of communications with these wireless peripherals may be used to compromise SLEM 5. Communication paths outside the physical protection of a controlled boundary are exposed to the possibility of interception and modification. Protecting the confidentiality and integrity of communications with wireless peripherals can be accomplished by physical means (e.g., employing physical barriers to wireless radio frequencies) or by logical means (e.g., employing cryptographic techniques). If physical means of protection are employed, then logical means (cryptography) do not have to be employed, and vice versa. If the wireless peripheral is only passing telemetry data, encryption of the data may not be required.

Who does this work

8 NICE work roles and 7 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-261346r996496_chk)

Verify that SLEM 5 has no wireless network adapters enabled with the following command: > sudo wicked show all ... wlan0 up link: #3, state up, mtu 1500 type: wireless, hwaddr 06:00:00:00:00:02 config: wicked:xml:/etc/wicked/ifconfig/wlan0.xml leases: ipv4 dhcp granted addr: ipv4 10.0.0.101/16 [dhcp] route: ipv4 default via 10.0.0.1 proto dhcp If a wireless interface is configured and has not been documented and approved by the AO, this is a finding.

Fix Text (F-64983r996495_fix)

Configure SLEM 5 to disable all wireless network interfaces with the following command: For each interface of type wireless, bring the interface into "down" state: > sudo wicked ifdown wlan0 For each interface of type wireless with a configuration type of "compat:suse:", remove the associated file: > sudo rm /etc/sysconfig/network/ifcfg-wlan0 For each interface of type wireless, for each configuration of type "wicked:xml:", remove the associated file or remove the interface configuration from the file. > sudo rm /etc/wicked/ifconfig/wlan0.xml
