A SAP system communicates with SAP clients, browsers, applications and other SAP systems via the local network. Data is also exchanged between SAP system components. In all cases, data which needs to be protected is transferred. This includes not only the data used to authenticate users (e.g. user name and password, cookies, certificates, etc.), but also business data processed as part of the activated functions.
