In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. Evaluate the Gateway log files and create ACL rules. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. Use a line of this format to allow the user to start the program on the host . The secinfo file is holding rules controlling which programs (based on their executable name or fullpath, if not in $PATH) can be started by which user calling from which host(s) (based on its hostname/ip-address) on which RFC Gateway server(s) (based on their hostname/ip-address). It is common to define this rule also in a custom reginfo file as the last rule. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. 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). Default values can be determined from the aggregated Gateway logging and used to assemble control data, and subsequently leverage the control data content for further use. so for me it should only be a warning/info-message. . This parameter will enable special settings that should be controlled in the configuration of reginfo file. All subsequent rules are not even checked. There is an SAP PI system that needs to communicate with the SLD. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. All programs started by hosts within the SAP system can be started on all hosts in the system. TP is a mandatory field in the secinfo and reginfo files. 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. (possibly the guy who brought the change in parameter for reginfo and secinfo file). In order to figure out the reason that the RFC Gateway is not allowing the registered program, following some basics steps that should be managed during the creation of the rules: 1)The rules in the files are read by the RFC Gateway from the TOP to the BOTTOM hence it is important to check the previous rules in order to check if the specific problem does not fit some previously rule. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . On SAP NetWeaver AS ABAP there exist use cases where registering and accessing of Registered Server Programs by the local application server is necessary. There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. RFCs between RFC clients using JCo/NCo or Registered Server Programs and the AS ABAP are typically controlled on network level only. Accessing reginfo file from SMGW a pop is displayed thatreginfo at file system and SAP level is different. Most common use-case is the SAP-to-SAP communication, in other words communication via RFC connections between SAP NetWeaver AS systems, but also communication from RFC clients using the SAP Java Connector (JCo) or the SAP .NET Connector (NCo) to SAP NetWeaver systems. Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. To mitigate this we should look if it is generated using a fixed prefix and use this as a pattern with an ending wildcard in order to reduce the effective values, e.g., TP=Trex__*, which would still be better than TP=*`. In addition, the existing rules on the reginfo/secinfo file will be applied, even on Simulation Mode. This means that if the file is changed and the new entries immediately activated, the servers already logged on will still have the old attributes. The first letter of the rule can begin with either P (permit) or D (deny). Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. 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. They are: The diagram below shows the workflow of how the RFC Gateway works with the security rules and the involved parameters, like the Simulation Mode. In SAP NetWeaver Application Server Java: The SCS instance has a built-in 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 So lets shine a light on security. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. After an attack vector was published in the talk SAP Gateway to Heaven from Mathieu Geli and Dmitry Chastuhin at OPDCA 2019 Dubai (https://github.com/gelim/sap_ms) the RFC Gateway security is even more important than ever. About this page This is a preview of a SAP Knowledge Base Article. While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. This publication got considerable public attention as 10KBLAZE. The parameter is gw/logging, see note 910919. Its location is defined by parameter gw/sec_info. Always document the changes in the ACL files. Part 7: Secure communication Based on the original Gateway log files in the system, default values can be determined and generated for the ACL files directly after the evaluation of the data found. Please make sure you have read at least part 1 of this series to be familiar with the basics of the RFC Gateway and the terms i use to describe things. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. Its location is defined by parameter gw/reg_info. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. 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 RFC Gateway can be used to proxy requests to other RFC Gateways. Haben Support Packages in der Queue Verbindungen zu Support Packages einer anderen Komponente (weitere Vorgngerbeziehung, erforderliches CRT) wird die Queue um weitere Support Packages erweitert, bis alle Vorgngerbeziehungen erfllt sind. Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. If someone can register a "rogue" server in the Message Server, such rogue server will be included in the keyword "internal" and this could open a security hole. Part 4: prxyinfo ACL in detail. Part 5: ACLs and the RFC Gateway security. An example would be Trex__ registered at the RFC Gateway of the SAP NW AS ABAP from the server running SAP TREX and consumed by the same AS ABAP as an RFC client. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. As i suspect it should have been registered from Reginfo file rather than OS. With this rule applied you should properly secure access to the OS (e.g., verify if all existing OS users are indeed necessary, SSH with public key instead of user+pw). If we do not have any scenarios which relay on this use-case we are should disable this functionality to prevent from misuse by setting profile parameter gw/rem_start = DISABLED otherwise we should consider to enforce the usage of SSH by setting gw/rem_start = SSH_SHELL. Add a Comment Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. The SAP note1689663has the information about this topic. Part 5: ACLs and the RFC Gateway security. 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. 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: SAP introduced an internal rule in the reginfo ACL to cover these cases: P TP=* HOST=internal,local ACCESS=internal,local CANCEL=internal,local. Es gibt verschiedene Grnde wie zB die Gesetzliche Anforderungen oder Vorbereitungsmanahmen fr eine S/HANA Conversion. 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. 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. HOST = servername, 10. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. The message server port which accepts registrations is defined by profile parameter rdisp/msserv_internal. Specifically, it helps create secure ACL files. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. In SAP NetWeaver Application Server ABAP: Every Application Server has a built-in RFC Gateway. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. You have an RFC destination named TAX_SYSTEM. The first letter of the rule can be either P (for Permit) or D (for Deny). If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. The reginfo file has the following syntax. The wildcard * should be strongly avoided. secinfo: P TP=* USER=* USER-HOST=* HOST=*. Hufig ist man verpflichtet eine Migration durchzufhren. Only clients from the local application server are allowed to communicate with this registered program. Part 2: reginfo ACL in detail However, you still receive the "Access to registered program denied" / "return code 748" error. Besttigen Sie den auftauchenden Hinweis und vergeben Sie fr die gewnschten Gruppen zumindest das folgende Recht: Allgemein --> Allgemein --> Objekte Anzeigen. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks.

Dieses Verfahren ist zwar sehr restriktiv, was fr die Sicherheit spricht, hat jedoch den sehr groen Nachteil, dass in der Erstellungsphase immer Verbindungen blockiert werden, die eigentlich erwnscht sind. 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 ). You can define the file path using profile parameters gw/sec_infoand gw/reg_info. For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter. What is important here is that the check is made on the basis of hosts and not at user level. In production systems, generic rules should not be permitted. Falls es in der Queue fehlt, kann diese nicht definiert werden. 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. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. 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 RFC Gateway can be seen as a communication middleware. Thus, part of your reginfo might not be active.The gateway is logging an error while performing name resolution.The operating system / DNS took 5 seconds to reply - 5006ms per the error message you posted; and the response was "host unknown".If the "HOST" argument on the reginfo rule from line 9 has only one host, then the whole rule is ignored as the Gateway could not determine the IP address of the server.Kind regards. You have a non-SAP tax system that needs to be integrated with SAP. It is common and recommended by many resources to define the following rule in a custom prxyinfo ACL: With this, all requests from the local system, as well as all application servers of the same system, will be proxied by the RFC Gateway to any destination or end point. The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. 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. You must keep precisely to the syntax of the files, which is described below. 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. Use host names instead of the IP address. With this rule applied for example any user with permissions to create or edit TCP/IP connections in transaction SM59 would be able to call any executable or script at OS level on the RFC Gateway server in the context of the user running the RFC gateway process. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. You can also control access to the registered programs and cancel registered programs. We solved it by defining the RFC on MS. The RFC library provides functions for closing registered programs. 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). Example Example 1: 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. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. This way, each instance will use the locally available tax system. 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. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. 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. The Solution Manager (SolMan) system has only one instance, running at the host sapsmci. The keyword internal will be substituted at evaluation time by a list of hostnames of application servers in status ACTIVE which is periodically sent to all connected RFC Gateways. Dieses Verfahren ist zwar sehr restriktiv, was fr die Sicherheit spricht, hat jedoch den sehr groen Nachteil, dass in der Erstellungsphase immer Verbindungen blockiert werden, die eigentlich erwnscht sind. The wildcard * should not be used at all. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. Part 6: RFC Gateway Logging. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. This section contains information about the RFC Gateway ACLs, and examples of landscapes and rules.The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. This is for clarity purposes. 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. Read more. You have already reloaded the reginfo file. The RFC Gateway is capable to start programs on the OS level. Somit knnen keine externe Programme genutzt werden. Part 8: OS command execution using sapxpg. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. 2. Here are some examples: At the application server #1, with hostname appsrv1: At the application server #2, with hostname appsrv2: The SAP KBA2145145has a video illustrating how the secinfo rules work. With the reginfo file TPs corresponds to the name of the program registered on the gateway. 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 gateway replaces this internally with the list of all application servers in the SAP system. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. The default rule in prxyinfo ACL (as mentioned in part 4) is enabled if no custom ACL is defined. Very good post. Of course the local application server is allowed access. Thank you! USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. If the option is missing, this is equivalent to HOST=*. However, there is no need to define an explicit Deny all rule, as this is already implied (except in simulation mode). On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. Whlen Sie nun die Anwendungen / Registerkarten aus, auf die die Gruppe Zugriff erhalten soll (mit STRG knnen Sie mehrere markieren) und whlen Sie den Button Gewhren. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. 1. other servers had communication problem with that DI. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). The secinfo security file is used to prevent unauthorized launching of external programs. 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. A combination of these mitigations should be considered in general. 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. How can I quickly migrate SAP custom code to S/4HANA? Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. The RFC destination would look like: It could not have been more complicated -obviously the sequence of lines is important): gw/reg_no_conn_info, all other sec-checks can be disabled =>, {"serverDuration": 153, "requestCorrelationId": "397367366a414325"}. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). Furthermore the means of some syntax and security checks have been changed or even fixed over time. In these cases the program alias is generated with a random string. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. 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. If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. See the examples in the note1592493; 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 will continue following the old rules; 3)The rules in the secinfo and reginfo file do not always use the same syntax, it depends of the VERSION defined in the file. This would cause "odd behaviors" with regards to the particular RFC destination. RFC had issue in getting registered on DI.

BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. Part 8: OS command execution using sapxpg. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. The Gateway is a central communication component of an SAP system. 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 . Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. Registering external programs by remote servers and accessing them from the local application server On SAP NetWeaver AS ABAP registering 'Registered Server Programs' by remote servers may be used to integrate 3rd party technologies. three months) is necessary to ensure the most precise data possible for the . In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. Most of the cases this is the troublemaker (!) For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system.The secinfo file has rules related to the start of programs by the local SAP instance. 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.
