Vulnerability discussion

The screen lock timeout must be set to a value that helps protect the device from unauthorized access. Having a too-long timeout would increase the window of opportunity for adversaries who gain physical access to the mobile device through loss, theft, etc. Such devices are much more likely to be in an unlocked state when acquired by an adversary, thus granting immediate access to the data on the mobile device. The maximum timeout period of 15 minutes has been selected to balance functionality and security; shorter timeout periods may be appropriate, depending on the risks posed to the mobile device.SFR ID: FMT_SMF.1.1 #02

Check content

This validation procedure is performed on both the MDM Administration Console and the LG Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Maximum time to lock" setting in the MDM console. 2. Verify the value of the setting is 15 minutes or less. On the LG Android device: 1. Unlock the device 2. Navigate to the screen timeout setting: Settings >> Display >> Screen timeout 3. Stop all activity on the device for 15 minutes. If the "maximum time to lock" setting is not set to 15 minutes, or if the user does not have to unlock the device after 15 minutes of inactivity, this is a finding.

Fix text

Configure the mobile device to lock the device display after 15 minutes (or less) of inactivity. On the MDM Administration Console, set the "Maximum time to lock" value to 15 minutes (or less).

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.
