TLS is an application-independent security protocol defined by the IETF (Internet Engineering Task Force) that provides encryption and data integrity between two communicating applications. TLS (Transport Layer Security) is able to protect SIP signaling messages against loss of integrity, loss of confidentiality, and against replay. It is defined in IETF RFC 2246, The TLS Protocol, Version 1.0.
TLS (Transport Layer Security) Support - Network Connections
For network connections, the TLS (Transport Layer Security) support feature provides for secure signaling based on TCP and the TLS protocols.
TLS (Transport Layer Security) Support - Subscriber Access
For subscriber access, the TLS (Transport Layer Security) support feature provides for secure signaling based on TCP and the TLS protocols.
TLS (Transport Layer Security) Support - Subscriber Access - Implementation and Usage
The TLS (Transport Layer Security) Support - Subscriber Access Feature can be used in different implementations and scenarios.
CA Certificates and their Usage
CA certificates are used so that their signature can be compared against the CA signature within the certificate being offered by the peer. CA certificates can be stored either all within one file or as separate files.
Transparency of Features and Services
Features and services on Lotus Sametime Unified Telephony are transparent to the node to which the EP (Endpoint) has a TLS (Transport Layer Security) connection. This allows the EPs to be registered across two nodes in a load sharing arrangement.
Important topics of PAM framework are described here.
CLI User Management
The resilient telephony platform (RTP) of the Telephony Control server implements its own user management. Creation, modification, and deletion of users, password handling, handling of privileges, and so forth, are completely managed by the management function application programming interface (API). This API also controls the user access to the management functionality (user identification and authorization).
