   A hospital uses Cisco UCM with a large number of shared clinical workstations that have the Cisco Jabber softphone installed. A recent security audit revealed that several user accounts have weak passwords and that some users share their credentials with colleagues. The IT director is concerned about toll fraud via compromised credentials and wants to implement a control that directly reduces the risk of credential-based toll fraud with minimal user disruption. Which control should the administrator implement FIRST?

   • AEnforce a strong password policy and enable account lockout after a specified number of failed attempts.
   • BDisable the Jabber softphone on all clinical workstations and require users to use physical desk phones only.
   • CImplement a translation pattern that blocks all calls from the clinical workstations' IP subnets.
   • DChange all user passwords to a temporary default and require a change at next login.
