...Student’s Name Case Study 1: Florida Department of Management Services, Part 1 CIS 505 Communication Technologies Professor’s name May 5, 2013 Analyze the security mechanisms needed to protect the DMS systems from both state employees and users accessing over the internet: Department of Management Services (DMS) has chosen to expand their applications and services via TCP/IP and Internet access. DMS uses a widely used proprietary scheme: IBM’s Systems Network Architecture (SNA) which provides support for TCP/IP (Transmission Control Protocol/Internet Protocol). SNA architecture is projected to remain important for some years to come. Implementing standardized protocol architectures allow DMS ongoing communication with suppliers, vendors, customers, and employees across the state, thereby improving overall productivity. Two protocols architectures have served as the basis for the development of interoperable protocol standards: the TCP/IP protocol suite and the OSI (Open Systems Interconnection) reference model which organizes the communication task in relatively five independent layers: Application layer, Host–to-host, or transport layer, Internet layer, Network access layer, and physical layer as each layer provides a portion of the total communications function required for distributed applications. (Stallings, 2009). Furthermore, TCP/IP operates in a packet-switched format as it seeks to transmit in the most efficient manner at high rates of speed. The packet-switching...
