The Communications Server protects data and other resources on the system. Communications Server applications use RACF services to ensure that users requesting application access are identified and authenticated, and to protect data and other system resources from unauthorized access. The Communications Server safeguards the availability of the system by protecting against denial of service attacks from the network.
The Communications Server protects data in the network by supporting a variety of cryptographic-based network security protocols such as IPSec, SSL, and SNA Session Level Encryption. These security protocols ensure that data received is originated by the claimed sender (data origin authentication), that contents were unchanged in transit (message integrity), and that sensitive data is concealed using encryption (data privacy).
The Communications Server provides security event reporting to record potential security violations. These services may help you identify potential sources of subsequent attacks, respond more quickly to network attacks, and manage system resources during periods of high network traffic for key applications.
