secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . Part 4: prxyinfo ACL in detail. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. If the Gateway protections fall short, hacking it becomes childs play. File reginfocontrols the registration of external programs in the gateway. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. Most of the cases this is the troublemaker (!) Only clients from the local application server are allowed to communicate with this registered program. 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. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. 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. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. (any helpful wiki is very welcome, many thanks toIsaias Freitas). so for me it should only be a warning/info-message. 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. 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! If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. The RFC Gateway is capable to start programs on the OS level. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. The very first line of the reginfo/secinfo file must be "#VERSION=2"; Each line must be a complete rule (you cannot break the rule into two or more lines); The RFC Gateway will apply the rules in the same order as they appear in the file, and only the first matching rule will be used (similar to the behavior of a network firewall). Falls es in der Queue fehlt, kann diese nicht definiert werden. The local gateway where the program is registered can always cancel the program. The subsequent blogs of will describe each individually. P TP=
HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. 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). 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. 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. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. For example: The SAP KBAs1850230and2075799might be helpful. P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. 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 1: General questions about the RFC Gateway and RFC Gateway security. While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. Someone played in between on reginfo file. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. 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. Checking the Security Configuration of SAP Gateway. Part 2: reginfo ACL in detail. In case you dont want to use the keyword, each instance would need a specific rule. 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. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). 3. Even if the system is installed with an ASCS instance (ABAP Central Services comprising the message server and the standalone enqueue server), a Gateway can still be configured on the ASCS instance. This diagram shows all use-cases except `Proxy to other RFC Gateways. Privacy |
Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Maybe some security concerns regarding the one or the other scenario raised already in you head. Access to the ACL files must be restricted. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. Ergebnis Sie haben eine Queue definiert. From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. 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. 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. Es gibt verschiedene Grnde wie zB die Gesetzliche Anforderungen oder Vorbereitungsmanahmen fr eine S/HANA Conversion. In production systems, generic rules should not be permitted. Part 2: reginfo ACL in detail. Part 6: RFC Gateway Logging. CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. Part 7: Secure communication Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. Datenbankschicht: In der Datenbank, welche auf einem Datenbankserver liegt, werden alle Daten eines Unternehmens gesichert. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. 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 other parts are not finished, yet. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. 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. Limiting access to this port would be one mitigation. This would cause "odd behaviors" with regards to the particular RFC destination. Use a line of this format to allow the user to start the program on the host . 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. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Access to this ports is typically restricted on network level. (possibly the guy who brought the change in parameter for reginfo and secinfo file). A rule defines. Hello Venkateshwar, thank you for your comment. You have already reloaded the reginfo file. Trademark. 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 first letter of the rule can be either P (for Permit) or D (for Deny). 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. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. To edit the security files,you have to use an editor at operating system level. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. 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 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 . Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. 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. 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. P SOURCE=* DEST=*. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. Part 8: OS command execution using sapxpg. Somit knnen keine externe Programme genutzt werden. The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. Check the secinfo and reginfo files. 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). Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. If the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. If no access list is specified, the program can be used from any client. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter. 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 . Click more to access the full version on SAP for Me (Login . 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). With secinfo file this corresponds to the name of the program on the operating system level. Each line must be a complete rule (rules cannot be broken up over two or more lines). 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. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. 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. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. 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. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. The secinfo file has rules related to the start of programs by the local SAP instance. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. 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. Please pay special attention to this phase! 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. There may also be an ACL in place which controls access on application level. All of our custom rules should bee allow-rules. 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. 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. 1. other servers had communication problem with that DI. Its location is defined by parameter 'gw/reg_info'. The RFC Gateway does not perform any additional security checks. 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. 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. This makes sure application servers must have a trust relation in order to take part of the internal server communication. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. 1. other servers had communication problem with that DI. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. three months) is necessary to ensure the most precise data possible for the connections used. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. 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). Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. 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 is the index value shown in the pop-up), Gateway, Security, length, line, rule, limit, abap , KBA , BC-CST-GW , Gateway/CPIC , Problem. However, you still receive the "Access to registered program denied" / "return code 748" error. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. Visit SAP Support Portal's SAP Notes and KBA Search. Sie knnen die Queue-Auswahl reduzieren. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. Please follow me to get a notification once i publish the next part of the series. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. 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. 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. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. . Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. 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 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 these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* The RFC library provides functions for closing registered programs. Please note: SNC User ACL is not a feature of the RFC Gateway itself. RFC had issue in getting registered on DI. Part 4: prxyinfo ACL in detail. 2. You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. Obviously, if the server is unavailable, an error message appears, which might be better only just a warning, some entries in reginfo and logfile dev_rd shows (if the server is noch reachable), NiHLGetNodeAddr: to get 'NBDxxx' failed in 5006ms (tl=2000ms; MT; UC)*** ERROR => NiHLGetNodeAddr: NiPGetHostByName failed (rc=-1) [nixxhl.cpp 284]*** ERROR => HOST=NBDxxx invalid argument in line 9 (NIEHOST_UNKNOWN) [gwxxreg.c 2897]. ABAP SAP Basis Release as from 7.40 . There are other SAP notes that help to understand the syntax (refer to the Related notes section below).
