SV-62559r1_rule The operating system must monitor for unauthorized connections of mobile devices to organizational information systems.

Vulnerability discussion

Mobile devices include portable storage media (e.g., USB memory sticks, external hard disk drives) and portable computing and communications devices with information storage capability (e.g., notebook/laptop computers, personal digital assistants, cellular telephones, digital cameras, audio recording devices). Organization-controlled mobile devices include those devices for which the organization has the authority to specify and the ability to enforce specific security requirements.Usage restrictions and implementation guidance related to mobile devices include configuration management, device identification and authentication, implementation of mandatory protective software (e.g., malicious code detection, firewall), scanning devices for malicious code, updating virus protection software, scanning for critical software updates and patches, conducting primary operating system (and possibly other resident software) integrity checks, and disabling unnecessary hardware (e.g., wireless, infrared).In order to detect unauthorized mobile device connections, organizations must first identify and document what mobile devices are authorized.

Check content

This check applies to the global zone only. Determine the zone that you are currently securing. # zonename If the command output is "global" this check applies. Determine if USB mass storage devices are locked out by the kernel. # grep "exclude: scsa2usb" /etc/system If the output of this command is not: exclude: scsa2usb this is a finding.

Fix text

The root role is required. This check applies to the global zone only. Determine the zone that you are currently securing. # zonename If the command output is "global" this check applies. Modify the /etc/system file. # pfedit /etc/system Add a line containing: exclude: scsa2usb Note that the global zone will need to be rebooted for this change to take effect.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
