Cloverleaf security
In Transaction Control Protocol/Internet Protocol (TCP/IP), connections are established through sockets. Each socket is an identifier for a particular service on a particular network node. The socket consists of a node address that identifies the node, and a port number, which identifies the service.
Each TCP/IP connection is a single pipe between a client TCP/IP socket and a server TCP/IP socket. The client socket originates a connection request and the server socket receives it.
In normal operations, the client communicates through a client socket and the host server communicates through a server socket. In security administration operations, the host server communicates through a client socket and the security server communicates through a server socket.
Secure Sockets Layer (SSL) is a protocol that forms a separate layer on top of TCP/IP. SSL supports both encryption and authentication in internet communications.
Advanced security and basic security both use SSL to implement a secure connection for system configuration. Advanced security, which requires security server, gives complete and detailed control over access to the system message brokering system.
