Mobile NAC
Using NAC in a mobile deployment, where workers connect over various wireless networks throughout the workday, involves challenges that are not present in a wired LAN environment. When a user is denied access because of a security concern, productive use of the device is lost, which can impact the ability to complete a job or serve a customer. In addition, automated remediation that takes only seconds on a wired connection may take minutes over a slower wireless data connection, bogging down the device. A mobile NAC solution gives system administrators greater control over whether, when and how to remediate the security concern. A lower-grade concern such as out-of-date antivirus signatures may result in a simple warning to the user, while more serious issues may result in quarantining the device. Policies may be set so that automated remediation, such as pushing out and applying security patches and updates, is withheld until the device is connected over a Wi-Fi or faster connection, or after working hours. This allows administrators to most appropriately balance the need for security against the goal of keeping workers productive.

Famous quotes containing the word mobile:
“From three to six months, most babies have settled down enough to be fun but aren’t mobile enough to be getting into trouble. This is the time to pay some attention to your relationship again. Otherwise, you may spend the entire postpartum year thinking you married the wrong person and overlooking the obvious—that parenthood can create rough spots even in the smoothest marriage.”
—Anne Cassidy (20th century)
