(SANS.org, 2012)
Keeping mobile devices secured on the network, however difficult, can be accomplished. Because of their portability, 100% security of devices cannot be guaranteed; securing the access to resources on the network, however, can. With these policies in place, Richman can be rest assured knowing that their network is guarded against both passive and active attacks.
