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,

Thus, all distributed applications, including remote logon, client/server, email, file transfer, Web access, and so on, can be secured (Stallings, 2009). Finally, Stallings (2009) has noted, “another relatively general-purpose solution is to implement security just above TCP by using Secure Sockets Layer (SSL) and the follow-on Internet standard Transport Layer Security (TLS). For full generality, SSL, (TLS) could be provided as part of the underlying protocol suite and therefore be transparent to applications. Alternatively, SSL can be embedded in specific packages.
Critique the transition process performed by the DMS in the case study. Then, recommend two (2) alternatives to the IP Infrastructure or applications not already mentioned in the case study: By the early 1990s, the Florida department of management services (DMS) had built up a large information systems network that serve state government agencies in 10 regional sites and connected these to the data center in Tallahassee. The network was based on the use of the proprietary systems network architecture (SNA) from IBM and mainframe at the data center that housed most of the applications. Although relatively happy with the SNA application and services by providing TCP/IP capability and internet access. The goal was met in a remarkably short time. Over the course of 30 months, DMS built a statewide TCP/IP network, began
