Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS).Before jumping to the ACLs themselves, here are a few general tips: A general reginfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): Usually, ACCESS is a list with at least all SAP servers from this SAP system. To set up the recommended secure SAP Gateway configuration, proceed as follows:. If no cancel list is specified, any client can cancel the program. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. This opensb the Gateway ACL Editor, where you can display the relevant files.. To enable system-internal communication, the files must contain the . Sobald dieses Recht vergeben wurde, taucht die Registerkarte auch auf der CMC-Startseite wieder auf. SMGW-->Goto -->External Functions --> External Security --> Maintenance of ACL files --> pop-up is shown as below: "Gateway content and file content for reginfo do not match starting with index <xx>" (xx is the index value shown in the . The Gateway uses the rules in the same order in which they are displayed in the file. The following syntax is valid for the secinfo file. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). Every line corresponds one rule. Another example would be IGS. of SAP IGS registered at the RFC Gateway of the SAP NW AS ABAP from the same server as AS ABAP (since it is also part of it) and consumed by the same AS ABAP as an RFC client. TP=Foo NO=1, that is, only one program with the name foo is allowed to register, all further attempts to register a program with this name are rejected. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. There are various tools with different functions provided to administrators for working with security files. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. secinfo: P TP=* USER=* USER-HOST=* HOST=*. 2) It is possible to change the rules in the files and reload its configuration without restart the RFC Gateway: open the transaction SMGW -> Goto -> expert functions -> external security -> reload However, in such situation, it is mandatory to de-register the registered program involved and reregister it again because programs already registered Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. Please make sure you have read part 1 4 of this series. Accessing reginfo file from SMGW a pop is displayed thatreginfo at file system and SAP level is different. This publication got considerable public attention as 10KBLAZE. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. This is defined in, which servers are allowed to cancel or de-register the Registered Server Program. Part 5: ACLs and the RFC Gateway security. For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). In case of TP Name this may not be applicable in some scenarios. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. This parameter will enable special settings that should be controlled in the configuration of reginfo file. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . The prxyinfo file is holding rules controlling which source systems (based on their hostname/ip-address) are allowed to talk to which destination systems (based on their hostname/ip-address) over the current RFC Gateway. Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. In summary, if the Simulation Mode is deactivated (parameter gw/sim_mode = 0; default value), the last implicit rule from the RFC Gateway will be Deny all as mentioned above, at the RFC Gateway ACLs (reginfo and secinfo) section. Part 3: secinfo ACL in detail. Part 7: Secure communication In addition to proper network separation, access to all message server ports can be controlled on network level by the ACL file specified by profile parameter ms/acl_file or more specific to the internal port by the ACL file specified by profile parameter ms/acl_file_int. Check the availability and use SM59 to ping all TP IDs.In the case of an SCS/ASCS instance, it cannot be reloaded via SMGW. The secinfo file has rules related to the start of programs by the local SAP instance. Changes to the reginfo rules are not immediately effective, even afterhaving reloaded the file (transaction SMGW, menu Goto -> Expert functions -> External security -> Reread / Read again). The solution is to stop the SLD program, and start it again (in other words, de-register the program, and re-register it). In some cases any application server of the same system may also need to de-register a Registered Server Program, for example if the reginfo ACL was adjusted for the same Registered Server Program or if the remote server crashed. We should pretend as if we would maintain the ACLs of a stand-alone RFC Gateway. If you have a program registered twice, and you restart only one of the registrations, one of the registrations will continue to run with the old rule (the one that was not restarted after the changes), and another will be running with the current rule (the recently restarted registration). If the Gateway protections fall short, hacking it becomes childs play. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. When using SNC to secure RFC destinations on AS ABAP the so called SNC System ACL, also known as System Authentication, is introduced and must be maintained accordingly. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. Program cpict4 is not permitted to be started. In case you dont want to use the keyword, each instance would need a specific rule. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. To prevent the list of application servers from tampering we have to take care which servers are allowed to register themselves at the Message Server as an application server. As i suspect it should have been registered from Reginfo file rather than OS. You can define the file path using profile parameters gw/sec_info and gw/reg_info. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. Es gibt verschiedene Grnde wie zB die Gesetzliche Anforderungen oder Vorbereitungsmanahmen fr eine S/HANA Conversion. To assign the new settings to the registered programs too (if they have been changed at all), the servers must first be deregistered and then registered again. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. With this rule applied any RFC enabled program on any of the servers covered by the keyword internal is able to register itself at the RFC Gateway independent from which user started the corresponding executable on OS level (again refer to 10KBLAZE). I think you have a typo. Datenbankschicht: In der Datenbank, welche auf einem Datenbankserver liegt, werden alle Daten eines Unternehmens gesichert. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. Access to the ACL files must be restricted. Please assist me how this change fixed it ? Save ACL files and restart the system to activate the parameters. The name of the registered program will be TAXSYS. The first line of the reginfo/secinfo files must be # VERSION = 2. Help with the understanding of the RFC Gateway ACLs (Access Control Lists) and the Simulation Mode, in order to help prepare production systems to have these security features enabled without disruptions. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. This page contains information about the RFC Gateway ACLs (reginfo and secinfo files), the Simulation Mode, as well as the workflow showing how the RFC Gateway works with regards to the ACLs versus the Simulation Mode. Check the above mentioned SAP documentation about the particular of each version; 4)It is possible to enable the RFC Gateway logging in order to reproduce the issue. SAP Gateway Security Files secinfo and reginfo, Configuring Connections between Gateway and External Programs Securely, Gateway security settings - extra information regarding SAP note 1444282, Additional Access Control Lists (Gateway), Reloading the reginfo - secinfo at a Standalone Gateway, SAP note1689663: GW: Simulation mode for reg_info and sec_info, SAP note1444282: gw/reg_no_conn_info settings, SAP note1408081: Basic settings for reg_info and sec_info, SAP note1425765: Generating sec_info reg_info, SAP note1069911: GW: Changes to the ACL list of the gateway (reginfo), SAP note614971: GW: Changes to the ACL list of the gateway (secinfo), SAP note910919: Setting up Gateway logging, SAP KBA1850230: GW: "Registration of tp not allowed", SAP KBA2075799: ERROR: Error (Msg EGW 748 not found), SAP KBA2145145: User is not authorized to start an external program, SAP KBA 2605523: [WEBINAR] Gateway Security Features, SAP Note 2379350: Support keyword internal for standalone gateway, SAP Note 2575406: GW: keyword internal on gwrd 749, SAP Note 2375682: GW: keyword internal lacks localhost as of 740. ooohhh my god, (It could not have been more complicated -obviously the sequence of lines is important): "# This must always be the last rule on the file see SAP note 1408081" + next line content, is not included as comment within the default-delivered reginfo file or secinfo file (after installation) -, this would save a lot ofwasted life time, gw/acl_mode: ( looks like to enable/disable the complete gw-security config, but ). There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. We can identify these use cases by going to transaction SMGW -> Goto -> Logged on Clients and looking for programs listed with System Type = Registered Server and Gateway Host set to any IP address or hostname not belonging to any application server of the same system. Sie knnen die Queue-Auswahl reduzieren. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). CANCEL is usually a list with all SAP servers from this system (or the keyword "internal"), and also the same servers as in HOSTS (as you must allow the program to de-register itself). In this case, the secinfo from all instances is relevant as the system will use the local RFC Gateway of the instance the user is logged on to start the tax program. ber das Dropdown-Men regeln Sie, ob und wie weit Benutzer der Gruppe, die Sie aktuell bearbeiten, selbst CMC-Registerkartenkonfigurationen an anderen Gruppen / Benutzern vornehmen knnen! To permit registered servers to be used by local application servers only, the file must contain the following entry. Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. This diagram shows all use-cases except `Proxy to other RFC Gateways. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Host Name (HOST=, ACCESS= and/or CANCEL=): The wildcard character * stands for any host name, *.sap.com for a domain, sapprod for host sapprod. The default rule in prxyinfo ACL (as mentioned in part 4) is enabled if no custom ACL is defined. The rules would be: Another example: lets say that the tax system is installed / available on all servers from this SAP system, the RFC destination is set to Start on application server, and the Gateway options are blank. Then the file can be immediately activated by reloading the security files. The reginfo file is holding rules controlling which remote servers (based on their hostname/ip-address) are allowed to either register, access or cancel which 'Registered Server Programs' (based on their program alias (also known as 'TP name')). The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. Another mitigation would be to switch the internal server communication to TLS using a so-called systemPKI by setting the profile parameter system/secure_communication = ON. The first letter of the rule can be either P (for Permit) or D (for Deny). The secinfo file has rules related to the start of programs by the local SAP instance. Part 4: prxyinfo ACL in detail. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. You have configured the SLD at the Java-stack of the SolMan system, using the RFC Gateway of the SolMans ABAP-stack. This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. In other words, the SAP instance would run an operating system level command. Part 6: RFC Gateway Logging Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. Part 4: prxyinfo ACL in detail In the slides of the talk SAP Gateway to Heaven for example a scenario is outlined in which a SAProuter installed on the same server as the RFC Gateway could be utilized to proxy a connection to local. In an ideal world each program alias of the relevant Registered Server Programs would be listed in a separate rule, even for registering program aliases from one of the hosts of internal. We can look for programs listed with Type = REGISTER_TP and field ADDR set to any IP address or hostname not belonging to any application server of the same system. HOST = servername, 10. The SAP note1689663has the information about this topic. The location of this ACL can be defined by parameter gw/acl_info. Such third party system is to be started on demand by the SAP system.Only the (SAP level) user IDs BOB and JOHN can start this program, and they will be logged on to one of the instances from this SAP system.You have an RFC destination named TAX_SYSTEM. In SAP NetWeaver Application Server ABAP: Every Application Server has a built-in RFC Gateway. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. Specifically, it helps create secure ACL files. What is important here is that the check is made on the basis of hosts and not at user level. The Gateway is a central communication component of an SAP system. Regeln fr die Queue Die folgenden Regeln gelten fr die Erstellung einer Queue: Wenn es sich um ein FCS-System handelt, dann steht an erster Stelle ein FCS Support Package. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. Environment. The RFC Gateway can be seen as a communication middleware. (any helpful wiki is very welcome, many thanks toIsaias Freitas). As i suspect it should have been registered from Reginfo file rather than OS. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. Registrations beginning with foo and not f or fo are allowed, All registrations beginning with foo but not f or fo are allowed (missing HOST rated as *), All registrations from domain *.sap.com are allowed. Most of the cases this is the troublemaker (!) RFC had issue in getting registered on DI. Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. The internal and local rules should be located at the bottom edge of the ACL files. NUMA steht fr Non-Uniform Memory Access und beschreibt eine Computer-Speicher-Architektur fr Multiprozessorsysteme, bei der jeder Prozessor ber einen eigenen, lokalen physischen Speicher verfgt, aber anderen Prozessoren ber einen gemeinsamen Adressraum direkten Zugriff darauf gewhrt (Distributed Shared Memory). No error is returned, but the number of cancelled programs is zero. This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. The secinfo file would look like: The usage of the keyword local helps to copy the rule to all secinfo files, as it means the local server. There may also be an ACL in place which controls access on application level. Part 6: RFC Gateway Logging. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. A rule defines. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. The default configuration of an ASCS has no Gateway. The default rules of reginfo and secinfo ACL (as mentioned in part 2 and part 3) are enabled if either profile parameter gw/acl_mode = 1 is set or if gw/reg_no_conn_info includes the value 16 in its bit mask, and if no custom ACLs are defined. Only clients from the local application server are allowed to communicate with this registered program. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. In this case the Gateway Options must point to exactly this RFC Gateway host. That part is talking about securing the connection to the Message Server, which will prevent tampering with they keyword "internal", which can be used on the RFC Gateway security ACL files. Each instance can have its own security files with its own rules. Program foo is only allowed to be used by hosts from domain *.sap.com. Part 5: ACLs and the RFC Gateway security. Limiting access to this port would be one mitigation. In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. Beachten Sie, da der SAP Patch Manager die Konfiguration Ihres SAP-Systems bercksichtigt und nur solche Support Packages in die Queue aufnimmt, die in Ihr System eingespielt werden drfen. Every attribute should be maintained as specific as possible. Of course the local application server is allowed access. three months) is necessary to ensure the most precise data possible for the connections used. Part 1: General questions about the RFC Gateway and RFC Gateway security. If the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. In case the files are maintained, the value of this parameter is irrelevant; gw/sim_mode: activates/deactivates the simulation mode (see the previous section of this WIKI page). You can also control access to the registered programs and cancel registered programs. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Only clients from domain *.sap.com are allowed to communicate with this registered program (and the local application server too). Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. So lets shine a light on security. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. Its location is defined by parameter gw/reg_info. Now 1 RFC has started failing for program not registered. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo So TP=/usr/sap///exe/* or even TP=/usr/sap//* might not be a comprehensive solution for high security systems, but in combination with deny-rules for specific programs in this directory, still better than the default rules. This is an allow all rule. Besttigen Sie den auftauchenden Hinweis und vergeben Sie fr die gewnschten Gruppen zumindest das folgende Recht: Allgemein --> Allgemein --> Objekte Anzeigen. The wildcard * should be strongly avoided. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. However, you still receive the "Access to registered program denied" / "return code 748" error. Program cpict4 is allowed to be registered by any host. We first registered it on the server it is defined (which was getting de-registered after a while so we registered it again through background command nohup *** & ), This solved the RFC communication on that Dialogue instance yet other Dialogue instances were not able to communicate on the RFC. The other parts are not finished, yet. The tax system is running on the server taxserver. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. Only the secinfo from the CI is applicable, as it is the RFC Gateway from the CI that will be used to start the program (check the Gateway Options at the screenshot above). The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. Again when a remote server of a Registered Server Program is going to be shutdown due to maintenance it may de-register its program from the RFC Gateway to avoid errors. All other programs from host 10.18.210.140 are not allowed to be registered. The RFC destination would look like: The secinfo files from the application instances are not relevant. (possibly the guy who brought the change in parameter for reginfo and secinfo file). However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). This allows default values to be determined for the security control files of the SAP Gateway (Reginfo; Secinfo; Proxyinfo) based on statistical data in the Gateway log. A custom allow rule has to be maintained on the proxying RFC Gateway only. The related program alias can be found in column TP Name: We can verify if the functionality of these Registered RFC Server programs is accessible from the AS ABAP by looking for a TCP/IP connection in transaction SM59 with Technical Settings Activation Type = Registered Server Program the corresponding Program ID and either no Gateway Options or connection details to any of the RFC Gateways belonging to the same system set: Please note: If the AS ABAP system has more than one application servers and therefore also more than one RFC Gateways there may be scenarios in which the Registered Server Program is registered at one specific RFC Gateway only.
