Communication support services

Communication support services include connectivity-related services

Some connectivity-related services are:
  • Authentication, which is the process of verifying the identity of a user or an application. The most common form of authentication is to require the user to enter a name and password to obtain access to a computer or an application.

  • Message integrity, which ensures that communication messages are intact and unaltered when they arrive at their destination.
  • Message confidentiality, which protects messages from unauthorized viewing, usually through encryption and decryption, during transmission.

Communication support services can also include other processing such as data compression or traffic-based accounting.

The database server provides extra security-related communication support services through plug-in software modules called Communication Support Modules (CSM). The database server uses the default authentication policy when you do not specify a communications support module.
