Detailed Policy Requirements: The BES must be configured so that all network file share access by BlackBerry users has been blocked. A high-level "deny all" Access Control Rule policy must be set up and assigned to each user or group account. Check Procedures: Verify all user and group accounts have been assigned an Access Control Rule. On the BES, do the following: Select at least 20 user/group accounts at random from different offices/sites. Go to each selected user/group account: BAS >> BlackBerry solution management >> User >> Manage users >> select user >> Access control rules tab. Verify each user has been assigned an Access Control Rule. Write down the name of each Access Control Rule assigned to each account (the settings of each rule will be verified in WIR1350-02). If any user or group account has not been assigned an Access Control Rule, this is a finding.
