reginfo and secinfo location in sap

Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. 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. 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 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. The location of this ACL can be defined by parameter gw/acl_info. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. 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. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. Its location is defined by parameter gw/prxy_info. 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. 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. Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. Only the first matching rule is used (similarly to how a network firewall behaves). where ist the hint or wiki to configure a well runing gw-security ? A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. Fr die gewnschten Registerkarten "Gewhren" auswhlen. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. 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. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. 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. Its location is defined by parameter gw/reg_info. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. It registers itself with the program alias IGS. at the RFC Gateway of the same application server. so for me it should only be a warning/info-message. 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 . Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. Access attempts coming from a different domain will be rejected. There are two different syntax versions that you can use (not together). 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. In SAP NetWeaver Application Server Java: The SCS instance has a built-in RFC Gateway. Most common use-case is the SAP-to-SAP communication, in other words communication via RFC connections between SAP NetWeaver AS systems, but also communication from RFC clients using the SAP Java Connector (JCo) or the SAP .NET Connector (NCo) to SAP NetWeaver systems. Part 7: Secure communication 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. This page contains information about the RFC Gateway ACLs (reginfo and secinfo files), the Simulation Mode, as well as the workflow showing how the RFC Gateway works with regards to the ACLs versus the Simulation Mode. 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. Part 8: OS command execution using sapxpg. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Part 5: Security considerations related to these ACLs. 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 case you dont want to use the keyword, each instance would need a specific rule. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. The RFC Gateway can be seen as a communication middleware. Save ACL files and restart the system to activate the parameters. As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. 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. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. 1408081 - Basic settings for reg_info and sec_info 1702229 - Precalculation: Specify Program ID in sec_info and reg_info. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. 2.20) is taken into account only if every comma-separated entry can be resolved into an IP address. Each instance can have its own security files with its own rules. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. 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! Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted. D prevents this program from being started. Sobald dieses Recht vergeben wurde, taucht die Registerkarte auch auf der CMC-Startseite wieder auf. So lets shine a light on security. There are other SAP notes that help to understand the syntax (refer to the Related notes section below). While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. Privacy | if the server is available again, this as error declared message is obsolete. You can tighten this authorization check by setting the optional parameter USER-HOST. Trademark. The first letter of the rule can begin with either P (permit) or D (deny). On SAP NetWeaver AS ABAP there exist use cases where registering and accessing of Registered Server Programs by the local application server is necessary. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). If the TP name itself contains spaces, you have to use commas instead. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. Part 3: secinfo ACL in detail. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. 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 secinfo file has rules related to the start of programs by the local SAP instance. 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. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. Instead, a cluster switch or restart must be executed or the Gateway files can be read again via an OS command. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. Giving more details is not possible, unfortunately, due to security reasons. 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. In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. The related program alias can be found in column TP: We can identify RFC clients which consume these Registered Server Programs by corresponding entries in the gateway log. 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: Please note: If the AS ABAP system has more than one application servers and therefore also more than one RFC Gateways there may be scenarios in which the Registered Server Program is registered at one specific RFC Gateway only. A custom allow rule has to be maintained on the proxying RFC Gateway only. Program cpict4 is allowed to be registered by any host. 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. The default rule in prxyinfo ACL (as mentioned in part 4) is enabled if no custom ACL is defined. Please make sure you have read part 1 4 of this series. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. You can also control access to the registered programs and cancel registered programs. 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). If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. Specifically, it helps create secure ACL files. 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 local gateway where the program is registered always has access. Part 4: prxyinfo ACL in detail. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. 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). Part 2: reginfo ACL in detail. Part 5: ACLs and the RFC Gateway security. 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. 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]. This publication got considerable public attention as 10KBLAZE. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. Another mitigation would be to switch the internal server communication to TLS using a so-called systemPKI by setting the profile parameter system/secure_communication = ON. You can define the file path using profile parameters gw/sec_info and gw/reg_info. 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. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. 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 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)). As such, it is an attractive target for hacker attacks and should receive corresponding protections. The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. If no access list is specified, the program can be used from any client. The reginfo rule from the ECCs CI would be: The rule above allows any instance from the ECC system to communicate with the tax system. Part 1: General questions about the RFC Gateway and RFC Gateway security. In summary, if the Simulation Mode is deactivated (parameter gw/sim_mode = 0; default value), the last implicit rule from the RFC Gateway will be Deny all as mentioned above, at the RFC Gateway ACLs (reginfo and secinfo) section. 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. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. Please pay special attention to this phase! This would cause "odd behaviors" with regards to the particular RFC destination. In production systems, generic rules should not be permitted. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. 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. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). Part 8: OS command execution using sapxpg. 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). 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 SAP note1689663has the information about this topic. 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. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . If this addition is missing, any number of servers with the same ID are allowed to log on. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. We solved it by defining the RFC on MS. The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. Hufig ist man verpflichtet eine Migration durchzufhren. 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. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Reread . Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. As separators you can use commas or spaces. In other words, the SAP instance would run an operating system level command. (any helpful wiki is very welcome, many thanks toIsaias Freitas). 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. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). 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. 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). If the option is missing, this is equivalent to HOST=*. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. The solution is to stop the SLD program, and start it again (in other words, de-register the program, and re-register it). 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. 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 SAP NetWeaver Application Server ABAP: Every Application Server has a built-in RFC Gateway. When using SNC to secure RFC destinations on AS ABAP the so called SNC System ACL, also known as System Authentication, is introduced and must be maintained accordingly. 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. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. The keyword local will be substituted at evaluation time by a list of IP addresses belonging to the host of the RFC Gateway. In addition, the existing rules on the reginfo/secinfo file will be applied, even on Simulation Mode. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. 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. Part 8: OS command execution using sapxpg. Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. All programs started by hosts within the SAP system can be started on all hosts in the system. 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. 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. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. 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 . Hinweis: Whlen Sie ber den Button und nicht das Dropdown-Men Gewhren aus! 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). 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. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. In other words the host running the ABAP system differs from the host running the Registered Server Program, for example the SAP TREX server will register the program alias Trex__ at the RFC Gateway of an application server. P SOURCE=* DEST=*. There are various tools with different functions provided to administrators for working with security files. 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. In other words, the SAP instance would run an operating system level command. Ergebnis Sie haben eine Queue definiert. 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. 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. The first letter of the rule can be either P (for Permit) or D (for Deny). It seems to me that the parameter is gw/acl_file instead of ms/acl_file. Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. While it is common and recommended by many resources to define this rule in a custom reginfo ACL as the last rule, from a security perspective it is not an optimal approach. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. Sie knnen die Queue-Auswahl reduzieren. Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. ABAP SAP Basis Release as from 7.40 . Somit knnen keine externe Programme genutzt werden. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. Falls es in der Queue fehlt, kann diese nicht definiert werden. This makes sure application servers must have a trust relation in order to take part of the internal server communication. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. The parameter is gw/logging, see note 910919. Part 6: RFC Gateway Logging. Beachten Sie, da der SAP Patch Manager die Konfiguration Ihres SAP-Systems bercksichtigt und nur solche Support Packages in die Queue aufnimmt, die in Ihr System eingespielt werden drfen. 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. The secinfosecurity file is used to prevent unauthorized launching of external programs. You have an RFC destination named TAX_SYSTEM. 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. If no cancel list is specified, any client can cancel the program. The PI system has one Central Instance (CI) running at the server sappici, and one application instance (running at the server sappiapp1). Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. Every line corresponds one rule. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen.
