Encryption is the word recently, especially in the post-snowden time we live in. And there is good reason for that; Your SAP system stores your business-critical data and might very well need additional protection when flowing through your SAP landscape.
The topic of SAP communication encryption is wide, it includes for example communication between SAP servers and the Database, between clients and servers and between SAP servers.
