Common examples are the program tp for transport management via STMS started on the RFC Gateway host of AS ABAP or the program gnetx.exe for the graphical screen painter started on the SAP GUI client host. This parameter will enable special settings that should be controlled in the configuration of reginfo file. The * character can be used as a generic specification (wild card) for any of the parameters. 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)). 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). On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. Part 5: ACLs and the RFC Gateway security. If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo D prevents this program from being started. 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). There may also be an ACL in place which controls access on application level. In production systems, generic rules should not be permitted. 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 . Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. All programs started by hosts within the SAP system can be started on all hosts in the system. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. Add a Comment Sobald dieses Recht vergeben wurde, taucht die Registerkarte auch auf der CMC-Startseite wieder auf. 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. Environment. 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. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. It seems to me that the parameter is gw/acl_file instead of ms/acl_file. The PI system has one Central Instance (CI) running at the server sappici, and one application instance (running at the server sappiapp1). Evaluate the Gateway log files and create ACL rules. Of course the local application server is allowed access. 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. 2. Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. 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). 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 addition, the RFC Gateway logging (see the SAP note910919) can be used to log that an external program was registered, but no Permit rule existed. The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. Very good post. 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. This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter. (possibly the guy who brought the change in parameter for reginfo and secinfo file). D prevents this program from being registered on the gateway. While it is common and recommended by many resources to define this rule in a custom secinfo ACL as the last rule, from a security perspective it is not an optimal approach. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. In addition, note that the system checks the case of all keywords and only takes keywords into account if they are written in upper case. Falls es in der Queue fehlt, kann diese nicht definiert werden. The RFC Gateway does not perform any additional security checks. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). This is a list of host names that must comply with the rules above. 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. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. About this page This is a preview of a SAP Knowledge Base Article. Someone played in between on reginfo file. With secinfo file this corresponds to the name of the program on the operating system level. Its location is defined by parameter gw/reg_info. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. 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. Besttigen Sie den auftauchenden Hinweis und vergeben Sie fr die gewnschten Gruppen zumindest das folgende Recht: Allgemein --> Allgemein --> Objekte Anzeigen. Part 6: RFC Gateway Logging There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. 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. If the TP name itself contains spaces, you have to use commas instead. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* To edit the security files,you have to use an editor at operating system level. 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. The subsequent blogs of will describe each individually. 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. 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. What is important here is that the check is made on the basis of hosts and not at user level. Terms of use |
Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. If the called program is not an RFC enabled program (compiled with the SAP RFC library) the call will time out, but the program is still left running on the OS level! Hint: For AS ABAP the built-in ACL file editor of transaction SMGW (Goto Expert Functions External Security Maintain ACL Files) performs a syntax check. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. 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. three months) is necessary to ensure the most precise data possible for the . 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. In case of TP Name this may not be applicable in some scenarios. All other programs starting with cpict4 are allowed to be started (on every host and by every user). Alerting is not available for unauthorized users. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. 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. For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. 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. The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. Somit knnen keine externe Programme genutzt werden. 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. File reginfocontrols the registration of external programs in the gateway. The local gateway where the program is registered always has access. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. A rule defines. This opensb the Gateway ACL Editor, where you can display the relevant files.. To enable system-internal communication, the files must contain the . The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). 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. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. 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. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. Part 5: ACLs and the RFC Gateway security. Somit knnen keine externe Programme genutzt werden. As i suspect it should have been registered from Reginfo file rather than OS. Alerting is not available for unauthorized users, Right click and copy the link to share this comment, Part 1: General questions about the RFC Gateway and RFC Gateway security, Part 8: OS command execution using sapxpg, Secure Server Communication in SAP Netweaver AS ABAP. It also enables communication between work or server processes of SAP NetWeaver AS and external programs. The wildcard * should be strongly avoided. You have an RFC destination named TAX_SYSTEM. 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. Programs within the system are allowed to register. Access attempts coming from a different domain will be rejected. 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. RFC had issue in getting registered on DI. The Stand-alone RFC Gateway: As a dedicated RFC Gateway serving for various RFC clients or as an additional component which may be used to extend a SAP NW AS ABAP or AS Java system. Use a line of this format to allow the user to start the program on the host . Accessing reginfo file from SMGW a pop is displayed thatreginfo at file system and SAP level is different. There are two different syntax versions that you can use (not together). Most of the cases this is the troublemaker (!) The RFC Gateway does not perform any additional security checks. In this case the Gateway Options must point to exactly this RFC Gateway host. A LINE with a HOST entry having multiple host names (e.g. (any helpful wiki is very welcome, many thanks toIsaias Freitas). Legal Disclosure |
For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). Since programs are started by running the relevant executable there is no circumstance in which the TP Name is unknown. 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. Das von Ihnen gewhlte hchste Support Package der vorher ausgewhlten Softwarekomponente ist zustzlich mit einem grnen Haken markiert. As soon as a program has registered in the gateway, the attributes of the retrieved entry (specifically ACCESS) are passed on to the registered program. 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. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET.
