Summary :
This SAP Note pertains to the configuration of security settings for external program registration and connection using parameters gw/acl_mode and gw/reg_no_conn_info. With the gw/acl_mode parameter, applicable from Kernel Release 720, you can enhance security by allowing only internal servers within the same system network or those specified in ACL files (gw/sec_info or gw/reg_info). When gw/acl_mode is set to 1, any external or unlisted server registrations are restricted. Additionally, the gw/reg_no_conn_info parameter can activate further security controls as described in Note 1444282. Proper configuration is essential for safeguarding SAP systems against unauthorized access and ensuring compliant operations.
