“As the communications industry explodes with new technologies that tie together security devices, buildings and computers, expanded options bring opportunities and challenges to security directors and system providers. On the Internet, you get instant multimedia information on virtually any subject. Downloaded information can be passed on to others with a few keystrokes on a laptop or desktop computer. Network security is a field unto itself, but there are problems besides data dabbling and corruption that need to be considered when using new communication technologies in conjunction with access control and alarm equipment. To take full advantage of the new technologies, today’s security director must understand networks. Working closely with the corporate information systems manager is one way to begin. Furthermore, there are many types of networks and new ones being developed every day. Today’s security director must work with other departments to take full advantage of a corporate communication network. Using the network can provide significant cost security monitoring system.
