For session security, SAP HANA XS automatically configures the session cookie xsSessionId with the attribute HttpOnly. However, the attribute secure is not supported. If you use a reverse proxy (instead of SAP Web Dispatcher) in your system landscape, you can add this attribute by configuring the reverse proxy with a header rewrite rule on the Set-Cookie header.
A token-based protection against cross-site request forgery (CSRF) is active by default in SAP Gateway and SAP HANA XS SAP Fiori OData services. It protects all modifying requests.
