IT policy rule Maximum Connection Heartbeat Period Maximum BlackBerry Disconnected Timeout Maximum BlackBerry Long Term Timeout Maximum BlackBerry Bluetooth Traffic Inactivity Timeout Maximum Smart Card Not Present Timeout Maximum Number of BlackBerry Transactions Maximum Bluetooth Range Maximum PC Disconnected Timeout Description This rule specifies the maximum heartbeat period, in seconds. During each heartbeat period, the paired BlackBerry device or computer sends a heartbeat, which the BlackBerry Smart Card Reader acknowledges. If either side does not send or acknowledge a heartbeat in the maximum heartbeat period, the BlackBerry device or computer closes the Bluetooth connection. When the Bluetooth connection closes, the disconnected timer starts if you or the user turned that feature on for the BlackBerry device or computer. The BlackBerry device or computer deletes the secure pairing PINs when the disconnected timer expires. You can use this IT policy rule to help prevent a user with malicious intent from using a low-level Bluetooth heartbeat to perform the following actions: • keep the Bluetooth connection open between the BlackBerry device or computer and the BlackBerry Smart Card Reader • keep the secure pairing PINs present for an extended period after the BlackBerry device and BlackBerry Smart Card Reader should close the Bluetooth connection This rule specifies the maximum time, in seconds, after a BlackBerry device and the BlackBerry Smart Card Reader close the Bluetooth connection between them that the disconnection timeout period expires. You can use the Force Erase All Keys on BlackBerry Disconnected Timeout IT policy rule to specify whether the BlackBerry device or computer delete the secure pairing PINs for the current connection to the BlackBerry Smart Card Reader when the disconnection timeout period expires. This rule specifies the maximum time, in hours, after the BlackBerry device and the BlackBerry Smart Card Reader open the secure pairing connection between them that the BlackBerry device and the BlackBerry Smart Card Reader delete the secure pairing information. This rule specifies the maximum time, in minutes, of inactivity over a Bluetooth connection between the BlackBerry Smart Card Reader and a BlackBerry device that the BlackBerry device and the BlackBerry Smart Card Reader wait before deleting the secure pairing information. This rule specifies the maximum time, in seconds, after a user removes the smart card from the BlackBerry Smart Card Reader that the secure pairing information is deleted from a BlackBerry device and the BlackBerry Smart Card Reader. This rule specifies the maximum number of transactions (smart card- related operations) that a BlackBerry device and the BlackBerry Smart Card Reader can send and receive before the secure pairing information is deleted from the BlackBerry device. This rule specifies the maximum power range, as a value between 30% (the shortest range) and 100% (the longest range), that the BlackBerry Smart Card Reader can use to send Bluetooth data packets. This rule specifies the maximum time, in seconds, after a computer and the BlackBerry Smart Card Reader close the Bluetooth connection between them that the secure pairing information for the closed connection is deleted from the computer and the BlackBerry Smart Card Reader. 13
