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. The secinfo file has rules related to the start of programs by the local SAP instance. From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. Checking the Security Configuration of SAP Gateway. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. 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 ). This is defined in, how many Registered Server Programs with the same name can be registered. three months) is necessary to ensure the most precise data possible for the connections used. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Besttigen Sie den auftauchenden Hinweis und vergeben Sie fr die gewnschten Gruppen zumindest das folgende Recht: Allgemein --> Allgemein --> Objekte Anzeigen. 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. Its location is defined by parameter gw/prxy_info. 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. 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. Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. About this page This is a preview of a SAP Knowledge Base Article. 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. 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. D prevents this program from being started. Part 4: prxyinfo ACL in detail 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). As such, it is an attractive target for hacker attacks and should receive corresponding protections. Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. 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. The name of the registered program will be TAXSYS. Every attribute should be maintained as specific as possible. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). This makes sure application servers must have a trust relation in order to take part of the internal server communication. 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. Please assist ASAP. Evaluate the Gateway log files and create ACL rules. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. Part 2: reginfo ACL in detail. A LINE with a HOST entry having multiple host names (e.g. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. 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 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). Click more to access the full version on SAP for Me (Login . From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. 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). As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. RFC had issue in getting registered on DI. E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* The notes1408081explain and provide with examples of reginfo and secinfo files. You can define the file path using profile parameters gw/sec_info and gw/reg_info. 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. 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. The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. secinfo: P TP=* USER=* USER-HOST=* HOST=*. If the TP name itself contains spaces, you have to use commas instead. A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. 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'. The related program alias also known as TP Name is used to register a 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. Please note: SNC User ACL is not a feature of the RFC Gateway itself. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. 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. In addition, the existing rules on the reginfo/secinfo file will be applied, even on Simulation Mode. The RFC Gateway does not perform any additional security checks. The simulation mode is a feature which could help to initially create the ACLs. 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. The subsequent blogs of will describe each individually. Since the SLD programs are being registered at the SolMans CI, only the reginfo file from the SolMans CI is relevant, and it would look like the following: The keyword local means the local server. RFCs between two SAP NetWeaver AS ABAP systems are typically controlled on network level only. 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. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. Part 3: secinfo ACL in detail. 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. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS). Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Please make sure you have read part 1 4 of this series. 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. While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. 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. Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. The Gateway uses the rules in the same order in which they are displayed in the file. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. The message server port which accepts registrations is defined by profile parameter rdisp/msserv_internal. Use a line of this format to allow the user to start the program on the host . Part 5: ACLs and the RFC Gateway security. Please note: The wildcard * is per se supported at the end of a string only. You dont need to define a deny all rule at the end, as this is already implicit (if there is no matching Permit rule, and the RFC Gateway already checked all the rules, the result will be Deny except when the Simulation Mode is active, see below). 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. Check out our SAST SOLUTIONS website or send us an e-mail us at sast@akquinet.de. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . At time of writing this can not be influenced by any profile parameter. So lets shine a light on security. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. Please assist me how this change fixed it ? However, you still receive the "Access to registered program denied" / "return code 748" error. If no access list is specified, the program can be used from any client. 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. 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. 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. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. To control access from the client side too, you can define an access list for each entry. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. P SOURCE=* DEST=*. There are other SAP notes that help to understand the syntax (refer to the Related notes section below). The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. In these cases the program alias is generated with a random string. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. Only clients from domain *.sap.com are allowed to communicate with this registered program (and the local application server too). Part 5: ACLs and the RFC Gateway security. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. 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. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. As separators you can use commas or spaces. 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 This ACL is applied on the ABAP layer and is maintained in transaction SNC0. Its location is defined by parameter gw/sec_info. The parameter is gw/logging, see note 910919. 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. 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. 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). Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. Part 3: secinfo ACL in detail The wildcard * should be strongly avoided. 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. 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 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. This opensb the Gateway ACL Editor, where you can display the relevant files.. To enable system-internal communication, the files must contain the . 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. This is because the rules used are from the Gateway process of the local instance. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. 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 7: Secure communication The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo All programs started by hosts within the SAP system can be started on all hosts in the system. Die Datei kann vermutlich nicht zum Lesen geffnet werden, da sie zwischenzeitlich gelscht wurde, oder die Berechtigungen auf Betriebssystemebene unzureichend sind. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. No error is returned, but the number of cancelled programs is zero. Part 2: reginfo ACL in detail. Part 5: ACLs and the RFC Gateway security. The other parts are not finished, yet. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. The RFC Gateway allows external RFC Server programs (also known as Registered Server or Registered Server Program) to register to itself and allows RFC clients to consume the functions offered by these programs. It is common to define this rule also in a custom reginfo file as the last rule. The secinfosecurity file is used to prevent unauthorized launching of external programs. if the server is available again, this as error declared message is obsolete. Please pay special attention to this phase! This is for clarity purposes. With secinfo file this corresponds to the name of the program on the operating system level. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. There may also be an ACL in place which controls access on application level. After the external program was registered, the ACCESS and CANCEL options will be followed as defined in the rule, if a rule existed. The SAP note1689663has the information about this topic. You have configured the SLD at the Java-stack of the SolMan system, using the RFC Gateway of the SolMans ABAP-stack. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). 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. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. Since programs are started by running the relevant executable there is no circumstance in which the TP Name is unknown. 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). In case of TP Name this may not be applicable in some scenarios. Somit knnen keine externe Programme genutzt werden. Danach wird die Queue neu berechnet. Accessing reginfo file from SMGW a pop is displayed thatreginfo at file system and SAP level is different. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. Part 2: reginfo ACL in detail 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 local gateway where the program is registered always has access. 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 following syntax is valid for the secinfo file.
