Like most big utilities, AEP's power plants, substations and other vital equipment are managed by a network that is separated from the company's business software with layers of authentication, and is not accessible via the Internet. Creating that separation, and making sure that separation is maintained, is among the most important things utilities can do to protect the grid's physical assets. (AP Photo/John Minchillo) (AP)
