A majority of IT managers believe the mobile workforce makes their networks more susceptible to malware and other threats. The survey of 450 IT managers found they are still at risk despite having antivirus products installed. 30 percent said an inability to reach mobile users disconnected from the network contributed to the intrusion or failure that allowed a virus onto their network. 15 percent of respondents cited the inability to monitor and remediate security issues outside of patch management. Another 15 percent said a lack of immediate feedback on the remediation status was a contributing factor.”]
