Wechseln Sie dazu auf die gewnschte Registerkarte (im Beispiel ist das Universen), whlen Sie Verwalten --> Sicherheit auf oberster Ebene --> Alle Universen (je nach Registerkarte unterscheidet sich der letzte Punkt). However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. It is common to define this rule also in a custom reginfo file as the last rule. As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo All other programs from host 10.18.210.140 are not allowed to be registered. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. secinfo: P TP=* USER=* USER-HOST=* HOST=*. Trademark. Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. 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. There are other SAP notes that help to understand the syntax (refer to the Related notes section below). if the server is available again, this as error declared message is obsolete. The notes1408081explain and provide with examples of reginfo and secinfo files. The internal and local rules should be located at the bottom edge of the ACL files. Program foo is only allowed to be used by hosts from domain *.sap.com. 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. Part 7: Secure communication secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. 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. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. 2. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. 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. 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. 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. RFCs between two SAP NetWeaver AS ABAP systems are typically controlled on network level only. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. Very good post. This publication got considerable public attention as 10KBLAZE. You have configured the SLD at the Java-stack of the SolMan system, using the RFC Gateway of the SolMans ABAP-stack. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. Programs within the system are allowed to register. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). Maybe some security concerns regarding the one or the other scenario raised already in you head. This parameter will enable special settings that should be controlled in the configuration of reginfo file. This could be defined in. 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. In other words, the SAP instance would run an operating system level command. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. 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. This makes sure application servers must have a trust relation in order to take part of the internal server communication. The SAP note1689663has the information about this topic. 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. Its functions are then used by the ABAP system on the same host. 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)). Part 5: ACLs and the RFC Gateway security. 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. Sobald dieses Recht vergeben wurde, taucht die Registerkarte auch auf der CMC-Startseite wieder auf. P means that the program is permitted to be registered (the same as a line with the old syntax). 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. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. Its location is defined by parameter gw/reg_info. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. The message server port which accepts registrations is defined by profile parameter rdisp/msserv_internal. 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. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. Ergebnis Sie haben eine Queue definiert. 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. Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. Most of the cases this is the troublemaker (!) For AS ABAP the ACLs should be maintained using the built-in ACL file editor of transaction SMGW (Goto Expert Functions External Security Maintain ACL Files). Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. Giving more details is not possible, unfortunately, due to security reasons. You have a non-SAP tax system that needs to be integrated with SAP. 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. Thank you! 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. 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. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. Please note: SNC System ACL is not a feature of the RFC Gateway itself. The RFC Gateway does not perform any additional security checks. Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. Only the first matching rule is used (similarly to how a network firewall behaves). The format of the first line is #VERSION=2, all further lines are structured as follows: Here the line starting with P or D, followed by a space or a TAB, has the following meaning: P means that the program is permitted to be started (the same as a line with the old syntax). Visit SAP Support Portal's SAP Notes and KBA Search. 3. In the following i will do the question and answer game to develop a basic understanding of the RFC Gateway, the RFC Gateway security and its related terms. RFC had issue in getting registered on DI. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. 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. All subsequent rules are not even checked. All other programs starting with cpict4 are allowed to be started (on every host and by every user). 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 the option is missing, this is equivalent to HOST=*. Furthermore the means of some syntax and security checks have been changed or even fixed over time. 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')). (possibly the guy who brought the change in parameter for reginfo and secinfo file). Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. Part 2: reginfo ACL in detail If the TP name itself contains spaces, you have to use commas instead. Please note: The wildcard * is per se supported at the end of a string only. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. This is a list of host names that must comply with the rules above. Part 3: secinfo ACL in detail where ist the hint or wiki to configure a well runing gw-security ? 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. Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. To edit the security files,you have to use an editor at operating system level. The Gateway is the technical component of the SAP server that manages the communication for all RFC-based functions. Falls es in der Queue fehlt, kann diese nicht definiert werden. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. Part 8: OS command execution using sapxpg. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Reread . This is an allow all rule. The following syntax is valid for the secinfo file. 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 . Always document the changes in the ACL files. Someone played in between on reginfo file. The wildcard * should not be used at all. Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. The RFC destination would look like: The secinfo files from the application instances are not relevant. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. I think you have a typo. Here, the Gateway is used for RFC/JCo connections to other systems. After reloading the file, it is necessary to de-register all registrations of the affected program, and re-register it again. A general secinfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): 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. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. 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. Part 4: prxyinfo ACL in detail Would you like more information on our SAST SUITE or would you like to find out more about ALL ROUND protection of your SAP systems? Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. 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. 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. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. 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. Thus, if an explicit Deny rule exists and it matches the request being analyzed by the RFC Gateway, the RFC Gateway will deny the request. We solved it by defining the RFC on MS. If you want to use this syntax, the whole file must be structured accordingly and the first line must contain the entry #VERSION=2 (written precisely in this format). After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). 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=*`. The name of the registered program will be TAXSYS. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. HOST = servername, 10. 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. 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. Part 1: General questions about the RFC Gateway and RFC Gateway security. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. 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!
