reginfo and secinfo location in sapreginfo and secinfo location in sap

Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. This could be defined in. 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. Giving more details is not possible, unfortunately, due to security reasons. In the gateway monitor (SMGW) choose Goto Logged On Clients , use the cursor to select the registered program, and choose Goto Logged On Clients Delete Client . The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. 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. Hinweis: Whlen Sie ber den Button und nicht das Dropdown-Men Gewhren aus! The location of this ACL can be defined by parameter gw/acl_info. Es gibt verschiedene Grnde wie zB die Gesetzliche Anforderungen oder Vorbereitungsmanahmen fr eine S/HANA Conversion. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. Es gibt folgende Grnde, die zum Abbruch dieses Schrittes fhren knnen: CANNOT_SKIP_ATTRIBUTE_RECORD: Die Attribute knnen in der OCS-Datei nicht gelesen werden. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. 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. Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. You have already reloaded the reginfo file. Configuring Connections between SAP Gateway and External Programs Securely, SAP Gateway Security Files secinfo and reginfo, Setting Up Security Settings for External Programs. Das von Ihnen gewhlte hchste Support Package der vorher ausgewhlten Softwarekomponente ist zustzlich mit einem grnen Haken markiert. The secinfosecurity file is used to prevent unauthorized launching of external programs. As we learned in part 2 SAP introduced the following internal rule in the in the reginfo ACL: P TP=* HOST=internal,local ACCESS=internal,local CANCEL=internal,local. However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. But also in some cases the RFC Gateway itself may 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. About the second comment and the error messages, those are messages related to DNS lookup.I believe that these are raised as errors because they have occurred during the parsing of the reginfo file. Use host names instead of the IP address. This way, each instance will use the locally available tax system. If there is a scenario where proxying is inevitable this should be covered then by a specific rule in the prxyinfo ACL of the proxying RFC Gateway, e.g.,: P SOURCE= DEST=internal,local. It seems to me that the parameter is gw/acl_file instead of ms/acl_file. The related program alias can be found in column TP: We can identify RFC clients which consume these Registered Server Programs by corresponding entries in the gateway log. All of our custom rules should bee allow-rules. A Stand-alone Gateway could utilise this keyword only after it was attached to the Message Server of AS ABAP and the profile parameter gw/activate_keyword_internal was set. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. Falls Sie danach noch immer keine Anwendungen / Registerkarten sehen, liegt es daran, dass der Gruppe / dem Benutzer das allgemeine Anzeigenrecht auf der obersten Ebene der jeweiligen Registerkarte fehlt. 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. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. 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. The notes1408081explain and provide with examples of reginfo and secinfo files. There are three places where we can find an RFC Gateway: The RFC Gateway is by default reachable via the services sapgw and sapgws which can be mapped to the ports 33 and 48. Die Datei kann vermutlich nicht zum Lesen geffnet werden, da sie zwischenzeitlich gelscht wurde, oder die Berechtigungen auf Betriebssystemebene unzureichend sind. Part 4: prxyinfo ACL in detail. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. The Gateway uses the rules in the same order in which they are displayed in the file. With secinfo file this corresponds to the name of the program on the operating system level. Its location is defined by parameter gw/prxy_info. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. Part 8: OS command execution using sapxpg. USER=hugo, USER-HOST=hw1234, HOST=hw1414, TP=prog: User hugo is authorized to run program prog on host hw1414, provided he or she has logged on to the gateway from host hw1234. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. For a RFC Gateway of AS Java or a stand-alone RFC Gateway this can be determined with the command-line tool gwmon by running the command gwmon nr= pf= then going to the menu by typing m and displaying the client table by typing 3. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. Part 5: ACLs and the RFC Gateway security. The secinfo file has rules related to the start of programs by the local SAP instance. Its location is defined by parameter gw/reg_info. The RFC Gateway does not perform any additional security checks. RFC had issue in getting registered on DI. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. As i suspect it should have been registered from Reginfo file rather than OS. How can I quickly migrate SAP custom code to S/4HANA? 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. If this addition is missing, any number of servers with the same ID are allowed to log on. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. The secinfosecurity file is used to prevent unauthorized launching of external programs. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. 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). As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: With this blogpost series i try to give a comprehensive explanation of the RFC Gateway Security: Part 1: General questions about the RFC Gateway and RFC Gateway security The syntax used in the reginfo, secinfo and prxyinfo changed over time. For example: you have changed to the rule related to the SLD_UC program, allowing a new server to communicate with it (you added the new server to the ACCESS option). In diesem Blog-Beitrag werden zwei von SAP empfohlene Vorgehensweisen zur Erstellung der secinfo und reginfo Dateien aufgefhrt mit denen die Security Ihres SAP Gateways verstrkt wird und wie der Generator dabei hilft. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. Then the file can be immediately activated by reloading the security files. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . HOST = servername, 10. 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. Once you have completed the change, you can reload the files without having to restart the gateway. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. 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. 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. The secinfo file has rules related to the start of programs by the local SAP instance. When using SNC to secure logon for RFC Clients or Registered Server Programs the so called SNC User ACL, also known as User Authentication, is introduced and must be maintained accordingly. This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. Part 2: reginfo ACL in detail Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. The RFC destination would look like: The secinfo files from the application instances are not relevant. Depending on the settings of the reginfo ACL a malicious user could also misuse this permissions to start a program which registers itself on the local RFC Gateway, e.g.,: Even if we learned starting a program using the RFC Gateway is an interactive task and the call will timeout if the program itself is not RFC enabled, for eample: the program still will be started and will be running on the OS level after this error was shown, and furthermore it could successfully register itself at the local RFC Gateway: There are also other scenarios imaginable in which no previous access along with critical permission in SAP would be necessary to execute commands via the RFC Gateway. This makes sure application servers must have a trust relation in order to take part of the internal server communication. In SAP NetWeaver Application Server Java: The SCS instance has a built-in RFC Gateway. Each instance can have its own security files with its own rules. Read more. In diesem Blog-Beitrag werden zwei von SAP empfohlene Vorgehensweisen zur Erstellung der secinfo und reginfo Dateien aufgefhrt mit denen die Security Ihres SAP Gateways verstrkt wird und wie der Generator dabei hilft. If the TP name itself contains spaces, you have to use commas instead. While typically remote servers start the to-be-registered program on the OS level by themselves, there may be cases where starting a program is used to register a Registered Server Program at the RFC Gateway. gw/acl_mode: this parameter controls the value of the default internal rules that the RFC Gateway will use, in case the reginfo/secinfo file is not maintained. If other SAP systems also need to communicate with it, using the ECC system, the rule need to be adjusted, adding the hostnames from the other systems to the ACCESS option. The message server port which accepts registrations is defined by profile parameter rdisp/msserv_internal. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. With this blogpost series i try to give a comprehensive explanation of the RFC Gateway Security: Part 1: General questions about the RFC Gateway and RFC Gateway security. (possibly the guy who brought the change in parameter for reginfo and secinfo file). This publication got considerable public attention as 10KBLAZE. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. 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 Part 4: prxyinfo ACL in detail. Maybe some security concerns regarding the one or the other scenario raised already in you head. Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. Despite this, system interfaces are often left out when securing IT systems. If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. The wild card character * stands for any number of characters; the entry * therefore means no limitation, fo* stands for all names beginning with fo; foo stands precisely for the name foo. The other parts are not finished, yet. Visit SAP Support Portal's SAP Notes and KBA Search. Every line corresponds one rule. File reginfocontrols the registration of external programs in the gateway. Part 2: reginfo ACL in detail. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. We can identify these use cases by going to transaction SMGW -> Goto -> Logged on Clients and looking for lines with System Type = Registered Server and Gateway Host = 127.0.0.1 (in some cases this may be any other IP address or hostname of any application server of the same system). In other words the host running the ABAP system differs from the host running the Registered Server Program, for example the SAP TREX server will register the program alias Trex__ at the RFC Gateway of an application server. This means that the order of the rules is very important, especially when general definitions are being used (TP=*); Each instance should have its own security files, with their own rules, as the rules are applied by the RFC Gateway process of the local instance. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. Notice that the keyword "internal" is available at a Standalone RFC Gateway (like the RFC Gateway process that runs at an SCS or ASCS instance) only after a certain SAP kernel version. The simulation mode is a feature which could help to initially create the ACLs. Trademark. Make sure that they are set as per the Notes: Note 1425765 - Generating sec_info reg_info Note 1947412 - MDM Memory increase and RFC connection error The local gateway where the program is registered always has access. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Ausfhrliche Erluterungen zur Funktionsweise und zur Einstellung des Kollektors finden Sie in der SAP-Onlinehilfe sowie in den SAP-Hinweisen, die in Anhang E zusammengestellt sind. 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). Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. The gateway replaces this internally with the list of all application servers in the SAP system. We made a change in the location of Reginfo and Secinfo file location we moved it to SYS directory and updated the profile parameter accordingly (instance profile). Add a Comment 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. With this blogpost series i try to give a comprehensive explanation of the RFC Gateway Security: Part 1: General questions about the RFC Gateway and RFC Gateway security. Here, the Gateway is used for RFC/JCo connections to other systems. Specifically, it helps create secure ACL files. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. 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. To edit the security files,you have to use an editor at operating system level. It registers itself with the program alias IGS. at the RFC Gateway of the same application server. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. The secinfo file from the CI would look like the below: In case you dont want to use the keywords local and internal, youll have to manually specify the hostnames. secinfo: P TP=* USER=* USER-HOST=* HOST=*. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. Furthermore the means of some syntax and security checks have been changed or even fixed over time. 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. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . Now 1 RFC has started failing for program not registered. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. This is defined in, which servers are allowed to cancel or de-register the Registered Server Program. Only clients from domain *.sap.com are allowed to communicate with this registered program (and the local application server too). 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.
