Volunteer labor is essential to the success of nonprofit organizations, but for IT managers and network security professionals, they also pose a security threat, especially when volunteers use their own laptops to access the network. One legal aid firm is addressing that threat through network access control (NAC).

"We have 12 locations, and at each location we sometimes have volunteer students who will come in," said Joseph Mays, director of IT at the Georgia Legal Services Program (GLSP). "I felt the need to be able to put a net out across our network so that when students came in and plugged in their laptops, they would not spread a virus that would completely shut down our network."
