      SSL (Secure Sockets Layer)

      An Overview on Secure Sockets Layer (SSL) The Secure Sockets Layer (SSL) protocol was developed by Netscape Communications, and enables secure communication over the Internet. SSL works at the transport layer of Transmission Control Protocol/Internet Protocol (TCP/IP), which makes the protocol independent of the application layer protocol functioning on top of it. SSL is an

      DFS (Distributed File System)

      DFS (Distributed File System) provides a mechanism for administrators to create logical views of folders and files, regardless of where those files are physically located on the network. DFS also allows administrators to distribute shared folders and work loads across several servers for more efficient network and server resources use. Fault tolerance network storage resources

      The Certificate Enrollment Process

      While encryption can be a robust security technology, users have to implement a public key infrastructure (PKI) to make it beneficial and trusted within an organization. The Windows 2000 and Windows Server 2003 PKI implementation resides in Certificate Services. A public key infrastructure is the collection of technology, protocols, services, standards, and policies that control
