Security through the network layers
Security mechanisms used by CICS® apply at different layers of a networking architecture such as TCP/IP.
- Application layer
- Security measures at this layer are application-specific.
- API layer
- Security protocols such as TLS operate above the TCP transport layer. These protocols use sockets to interface with the transport layer.
- Transport layer
- Security at the transport layer protects communication between two hosts, commonly web (HTTP) traffic.
- Network layer
- Security at this layer can provide protection transparently to applications.
