The building control systems market is no different. Networking technology develop- ment, customer demands, innovation in services, and open communication standards are driving the industry toward inter-networked buildings with ever-increasing services made possible by the flow of information. This information flow is not just between equipment on the building control system (BCS) subnetwork, but between the BCS subnet and corporate LAN, and between the building and off-site service partners: equipment ven- dors; gas, electric, and water utilities; security contractors; energy service contractors; telecommunication service providers; financial service providers; government regulating agencies; etc. . | Security Considerations 1 Running Head SECURITY CONSIDERATIONS FOR STORAGE AREA NETWORKS Security Considerations for Storage Area Networks Colleen Rhodes East Carolina University Security Considerations 2 Abstract In this paper I will describe Storage Area Networks SANs and the benefits they can bring as well as the emerging need for them in businesses today. I will discuss the importance of SAN security and why it is crucial for protecting a company s assets. This paper will touch upon common threats to a SAN and the precautions a business can take to protect itself. The main focus of this paper will be on securing a Storage Area Network by using best practices in setting up a SAN as well as securing the data on a day-to-day basis. Security Considerations 3 Security Considerations for Storage Area Networks What is a SAN As Wikipedia the free encyclopedia 2005 explains it a storage area network SAN is a network designed to attach computer storage devices such as disk array controllers and tape libraries to servers. SANs support disk mirroring backup and restore archival and retrieval of archived data data migration from one storage device to another and the sharing of data among different servers in a network. According to the GIAC Security Essentials Certification 2003 What is a San section para. 1 A Storage Area Network establishes a direct connection between storage element and servers or clients. This concept is similar to a Local Area Network LAN with the exception of allowing greater storage capacity and faster subnetworks. A SANs device allows multiple direct host connections or connections through a fiber hub or switch. A storage area network can offer many benefits to a business. It can allow storage and tape backup resources to be pooled and shared effectively among host servers. Storage area networks also separate storage traffic from general network traffic. Biran O.
