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. 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). Save ACL files and restart the system to activate the parameters. The Solution Manager (SolMan) system has only one instance, running at the host sapsmci. In a pure Java system, one Gateway is sufficient for the whole system because the instances do not use RFC to communicate. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. This publication got considerable public attention as 10KBLAZE. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. Part 2: reginfo ACL in detail Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. There are other SAP notes that help to understand the syntax (refer to the Related notes section below). The RFC destination would look like: The secinfo files from the application instances are not relevant. There may also be an ACL in place which controls access on application level. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. Part 2: reginfo ACL in detail. You have configured the SLD at the Java-stack of the SolMan system, using the RFC Gateway of the SolMans ABAP-stack. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. This is an allow all rule. 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)). If the Gateway protections fall short, hacking it becomes childs play. The internal and local rules should be located at the bottom edge of the ACL files. 2. This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). 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 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. D prevents this program from being registered on the gateway. Copyright | 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. Its location is defined by parameter gw/sec_info. The parameter is gw/logging, see note 910919. Read more. Examples of valid addresses are: Number (NO=): Number between 0 and 65535. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. All of our custom rules should bee allow-rules. Part 2: reginfo ACL in detail. Part 5: ACLs and the RFC Gateway security. The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. TP is restricted to 64 non-Unicode characters for both secinfo and reginfo files. Furthermore the means of some syntax and security checks have been changed or even fixed over time. The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. 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). In SAP NetWeaver Application Server Java: The SCS instance has a built-in RFC Gateway. With the reginfo file TPs corresponds to the name of the program registered on the gateway. 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. After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). Part 7: Secure communication 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. 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. Add a Comment Hello Venkateshwar, thank you for your comment. Successful and rejected registrations, and calls from registered programs can be ascertained using Gateway Logging with indicator S. Any error lines are put in the trace file dev_rd, and are not read in. This is defined in, how many Registered Server Programs with the same name can be registered. 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. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. 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. In these cases the program alias is generated with a random string. 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 . The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). RFC had issue in getting registered on DI. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. Part 4: prxyinfo ACL in detail. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. 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. Part 6: RFC Gateway Logging 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). Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. The RFC Gateway can be seen as a communication middleware. Maybe some security concerns regarding the one or the other scenario raised already in you head. We first registered it on the server it is defined (which was getting de-registered after a while so we registered it again through background command nohup *** & ), This solved the RFC communication on that Dialogue instance yet other Dialogue instances were not able to communicate on the RFC. 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. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. If you have a program registered twice, and you restart only one of the registrations, one of the registrations will continue to run with the old rule (the one that was not restarted after the changes), and another will be running with the current rule (the recently restarted registration). 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. After the external program was registered, the ACCESS and CANCEL options will be followed as defined in the rule, if a rule existed. 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. Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. All programs started by hosts within the SAP system can be started on all hosts in the system. For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. Check out our SAST SOLUTIONS website or send us an e-mail us at sast@akquinet.de. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. Part 4: prxyinfo ACL in detail You have an RFC destination named TAX_SYSTEM. For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). TP is a mandatory field in the secinfo and reginfo files. The RFC Gateway can be used to proxy requests to other RFC Gateways. 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). 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 . Part 6: RFC Gateway Logging. It also enables communication between work or server processes of SAP NetWeaver AS and external programs. Please pay special attention to this phase! The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. Program cpict4 is allowed to be registered by any host. All other programs starting with cpict4 are allowed to be started (on every host and by every user). The RFC Gateway hands over the request from the RFC client to the dispatcher which assigns it to a work process (AS ABAP) or to a server process (AS Java). Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. In this case, the secinfo from all instances is relevant as the system will use the local RFC Gateway of the instance the user is logged on to start the tax program. In other words, the SAP instance would run an operating system level command. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. The PI system has one Central Instance (CI) running at the server sappici, and one application instance (running at the server sappiapp1). 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. RFCs between two SAP NetWeaver AS ABAP systems are typically controlled on network level only. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. Click more to access the full version on SAP for Me (Login . 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). 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). In this case the Gateway Options must point to exactly this RFC Gateway host. Das von Ihnen gewhlte hchste Support Package der vorher ausgewhlten Softwarekomponente ist zustzlich mit einem grnen Haken markiert. Of course the local application server is allowed access. Program cpict4 is not permitted to be started. If the TP name itself contains spaces, you have to use commas instead. 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. There are two different versions of the syntax for both files: Syntax version 1 does not enable programs to be explicitly forbidden from being started or registered. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. 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). Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. 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). Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. Program foo is only allowed to be used by hosts from domain *.sap.com. 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. The syntax used in the reginfo, secinfo and prxyinfo changed over time. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. D prevents this program from being started. 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. Help with the understanding of the RFC Gateway ACLs (Access Control Lists) and the Simulation Mode, in order to help prepare production systems to have these security features enabled without disruptions. Terms of use | Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. 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. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. Its location is defined by parameter 'gw/reg_info'. Part 5: ACLs and the RFC Gateway security 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. 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"}. For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. 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. You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. A rule defines. P TP=* USER=* USER-HOST=internal HOST=internal. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Make sure that they are set as per the Notes: Note 1425765 - Generating sec_info reg_info Note 1947412 - MDM Memory increase and RFC connection error The keyword local will be substituted at evaluation time by a list of IP addresses belonging to the host of the RFC Gateway. 2. Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. 3. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. 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. *. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. The related program alias also known as TP Name is used to register a program at the RFC Gateway. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). All other programs from host 10.18.210.140 are not allowed to be registered. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. Thank you! Part 3: secinfo ACL in detail 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. In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_PRXY_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. 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. ber das Dropdown-Men regeln Sie, ob und wie weit Benutzer der Gruppe, die Sie aktuell bearbeiten, selbst CMC-Registerkartenkonfigurationen an anderen Gruppen / Benutzern vornehmen knnen! As we learned in part 4 SAP introduced the following internal rule in the in the prxyinfo ACL: While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . Every attribute should be maintained as specific as possible. As i suspect it should have been registered from Reginfo file rather than OS. Someone played in between on reginfo file. . How can I quickly migrate SAP custom code to S/4HANA? RFCs between RFC clients using JCo/NCo or Registered Server Programs and the AS ABAP are typically controlled on network level only. For this scenario a custom rule in the reginfo ACL would be necessary, e.g., P TP= HOST= ACCESS=internal,local CANCEL=internal,local,. Please assist ASAP. Part 6: RFC Gateway Logging. E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* 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. Specifically, it helps create secure ACL files. To edit the security files,you have to use an editor at operating system level. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. Benign programs to be started by the local RFC Gateway of a SAP NetWeaver AS ABAP are typically part of the SAP Kernel and located in the $(DIR_EXE) of the application server. The RFC Gateway is capable to start programs on the OS level. Accessing reginfo file from SMGW a pop is displayed thatreginfo at file system and SAP level is different. Its location is defined by parameter gw/prxy_info. P SOURCE=* DEST=*. You have already reloaded the reginfo file. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. Part 1: General questions about the RFC Gateway and RFC Gateway security. Only clients from the local application server are allowed to communicate with this registered program. This is a list of host names that must comply with the rules above. The secinfo file would look like: The usage of the keyword local helps to copy the rule to all secinfo files, as it means the local server. 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. This means that the sequence of the rules is very important, especially when using general definitions. It is common to define this rule also in a custom reginfo file as the last rule. Please note: SNC System ACL is not a feature of the RFC Gateway itself. 3. Part 5: ACLs and the RFC Gateway security. Please note: SNC User ACL is not a feature of the RFC Gateway itself. Additional ACLs are discussed at this WIKI page. In production systems, generic rules should not be permitted. About item #1, I will forward your suggestion to Development Support. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. 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). All subsequent rules are not even checked. A LINE with a HOST entry having multiple host names (e.g. Die Datei kann vermutlich nicht zum Lesen geffnet werden, da sie zwischenzeitlich gelscht wurde, oder die Berechtigungen auf Betriebssystemebene unzureichend sind. The RFC Gateway does not perform any additional security checks. secinfo: P TP=* USER=* USER-HOST=* HOST=*. All subsequent rules are not checked at all. Part 8: OS command execution using sapxpg. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. Part 7: Secure communication If USER-HOST is not specifed, the value * is accepted. In other words, the SAP instance would run an operating system level command. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. For example: The SAP KBAs1850230and2075799might be helpful. Program hugo is allowed to be started on every local host and by every user. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. The simulation mode is a feature which could help to initially create the ACLs. So lets shine a light on security. 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. RFC had issue in getting registered on DI. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS). 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 P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. 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 follow me to get a notification once i publish the next part of the series. About this page This is a preview of a SAP Knowledge Base Article. The SAP note1689663has the information about this topic. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Reread . The following steps usually need to be done manually to secure an SAP Gateway: Our SAST Interface Management module in the SAST SUITE provides support in hardening the SAP Gateway. 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. However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. three months) is necessary to ensure the most precise data possible for the connections used. In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_SEC_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. In other words the same host running the ABAP system is also running the SAP IGS, for example the integrated IGS (as part of SAP NW AS ABAP) may be started on the application servers host during the start procedure of the ABAP system. This parameter will enable special settings that should be controlled in the configuration of reginfo file. The first letter of the rule can begin with either P (permit) or D (deny).
