How can you ensure that SAP Systems trust the SAP web dispatcher that is forwarding X.509 client certificates?

• A. Set up a VPN connection
• B. Set Profile Parameter icm/trusted_reverse_proxy with PSE configuration
• C. Use a static IP for the web dispatcher
• D. None of the above

Answer: (B)

To ensure that SAP systems trust the SAP web dispatcher that is forwarding X.509 client certificates, it is essential to configure the profile parameter icm/trusted_reverse_proxy along with the appropriate PSE (Personal Security Environment) configuration. This configuration specifically allows the SAP system to recognize and trust incoming requests being forwarded from the web dispatcher, facilitating secure communications. When the web dispatcher forwards client certificates, the SAP system must verify these certificates to establish trust. By setting the icm/trusted_reverse_proxy parameter and correctly configuring the PSE, the system can manage the trust relationships necessary for secure operations. This ensures that the SAP environment recognizes the web dispatcher's authority in handling client certificates, allowing for secure client authentication. The other choices do not directly address the requirement of establishing trust for X.509 certificates. A VPN connection may help in securing the traffic but does not inherently relate to the trust in forwarded certificates. Using a static IP for the web dispatcher might aid in network stability but does not provide the necessary authentication assurance for the certificates being handled.
