Network & Communication Security
In SAP SRM, data exchange occurs with HTTPS connection using SSL encryption that is used to protect data from unauthorized access. SSL stands for Secure Socket Layer. While performing secure network and communication in SAP system, the following points can be considered −
- Network topology of SAP system
- Firewall configuration
- Transport layer security
- Using multiple network zones
In SAP SRM system, all the components that use HTTP protocol support encryption of data using SSL protocol and as per the protocol data are transferred. The components include confidential data like system password, etc. As per data transfer and protocol, you can also apply transport level security.
SSL can be used to increase the security between business systems and adapters, business system and integration server.

Activate the ICF service in one of the following ways −
- Using menu option Service/Host → Activate
- Using the context menu and choosing Activate Service
Default_host node is inactive in transaction SICF; the HTTP requests could result in ABAP runtime error RAISE_EXCEPTION with the following short text −
Exception condition "HOST_INACTIVE" triggered.
If a service is inactive in transaction SICF, an error text appears when you try to access the service.
To support internet protocols HTTP, HTTPS and SMTP — /default_host/sap/public/icman is activated in transaction.
This service is used to decide how HTTP requests are distributed.
