Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. Please assist ASAP. Please note: SNC System ACL is not a feature of the RFC Gateway itself. P TP=* USER=* USER-HOST=internal HOST=internal. Please note: SNC User ACL is not a feature of the RFC Gateway itself. Someone played in between on reginfo file. 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 reginfo file has the following syntax. The RFC Gateway can be seen as a communication middleware. Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. 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. 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). The SAP note1689663has the information about this topic. 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). 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. 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. 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). Very good post. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. You have already reloaded the reginfo file. HOST = servername, 10. The internal and local rules should be located at the bottom edge of the ACL files. Part 6: RFC Gateway Logging. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. . Notice that the keyword "internal" is available at a Standalone RFC Gateway (like the RFC Gateway process that runs at an SCS or ASCS instance) only after a certain SAP kernel version. If the TP name itself contains spaces, you have to use commas instead. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. Its location is defined by parameter gw/sec_info. 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. 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. The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. The message server port which accepts registrations is defined by profile parameter rdisp/msserv_internal. Part 8: OS command execution using sapxpg. 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. Then the file can be immediately activated by reloading the security files. 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. Fr die gewnschten Registerkarten "Gewhren" auswhlen. Every line corresponds one rule. You can define the file path using profile parameters gw/sec_infoand 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. The secinfosecurity file is used to prevent unauthorized launching of external programs. 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. 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. If the Gateway protections fall short, hacking it becomes childs play. In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. 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. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. It might be needed to add additional servers from other systems (for an SLD program SLD_UC, SLD_NUC, for example).CANCEL is usually a list with all SAP servers from this system (or the keyword "internal"), and also the same servers as in HOSTS (as you must allow the program to de-register itself).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): You have a Solution Manager system (dual-stack) that you will use as the SLD system. 1. other servers had communication problem with that DI. 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. 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). The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo Maybe some security concerns regarding the one or the other scenario raised already in you head. Access attempts coming from a different domain will be rejected. 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. 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. For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. Sobald dieses Recht vergeben wurde, taucht die Registerkarte auch auf der CMC-Startseite wieder auf. 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). 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. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. For this scenario a custom rule in the reginfo ACL would be necessary, e.g., P TP= HOST= ACCESS=internal,local CANCEL=internal,local,. 2. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. The wildcard * should be strongly avoided. Please pay special attention to this phase! Hello Venkateshwar, thank you for your comment. 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. Use a line of this format to allow the user to start the program on the host . Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. However, you still receive the "Access to registered program denied" / "return code 748" error. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. 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). Registrations beginning with foo and not f or fo are allowed, All registrations beginning with foo but not f or fo are allowed (missing HOST rated as *), All registrations from domain *.sap.com are allowed. 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. The RFC Gateway can be used to proxy requests to other RFC Gateways. 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. There is an SAP PI system that needs to communicate with the SLD. 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. Part 5: ACLs and the RFC Gateway security The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). ABAP SAP Basis Release as from 7.40 . 1. other servers had communication problem with that DI. 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. Part 7: Secure communication In production systems, generic rules should not be permitted. The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. 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. The default rules of reginfo and secinfo ACL (as mentioned in part 2 and part 3) are enabled if either profile parameter gw/acl_mode = 1 is set or if gw/reg_no_conn_info includes the value 16 in its bit mask, and if no custom ACLs are defined. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. The Gateway is a central communication component of an SAP system. Part 7: Secure communication Its functions are then used by the ABAP system on the same host. Furthermore the means of some syntax and security checks have been changed or even fixed over time. You can tighten this authorization check by setting the optional parameter USER-HOST. The local gateway where the program is registered can always cancel the program. I think you have a typo. TP is a mandatory field in the secinfo and reginfo files. Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. The secinfo file has rules related to the start of programs by the local SAP instance. 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. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. This could be defined in. If no cancel list is specified, any client can cancel the program. Its location is defined by parameter 'gw/reg_info'. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. This is because the rules used are from the Gateway process of the local instance. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS).Before jumping to the ACLs themselves, here are a few general tips: A general reginfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): Usually, ACCESS is a list with at least all SAP servers from this SAP system. 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 RFC Gateway is capable to start programs on the OS level. As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: But also in some cases the RFC Gateway itself may need to de-register a Registered Server Program, for example if the reginfo ACL was adjusted for the same Registered Server Program or if the remote server crashed. 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). Falls es in der Queue fehlt, kann diese nicht definiert werden. 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. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. 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. Please make sure you have read part 1 4 of this series. It is common to define this rule also in a custom reginfo file as the last rule. Its location is defined by parameter gw/reg_info. Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . If someone can register a "rogue" server in the Message Server, such rogue server will be included in the keyword "internal" and this could open a security hole. Host Name (HOST=, ACCESS= and/or CANCEL=): The wildcard character * stands for any host name, *.sap.com for a domain, sapprod for host sapprod. Copyright |
As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. 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! Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. RFCs between two SAP NetWeaver AS ABAP systems are typically controlled on network level only. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. The first letter of the rule can begin with either P (permit) or D (deny). 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. Someone played in between on reginfo file. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. If the option is missing, this is equivalent to HOST=*. Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. Somit knnen keine externe Programme genutzt werden. Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. Programs within the system are allowed to register. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. 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 local gateway where the program is registered always has access. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. See the examples in the note1592493; 2)It is possible to change the rules in the files and reload its configuration without restart the RFC Gateway: open the transaction SMGW -> Goto -> expert functions -> external security -> reload However, in such situation, it is mandatory to de-register the registered program involved and reregister it again because programs already registered will continue following the old rules; 3)The rules in the secinfo and reginfo file do not always use the same syntax, it depends of the VERSION defined in the file. In an ideal world each program alias of the relevant Registered Server Programs would be listed in a separate rule, even for registering program aliases from one of the hosts of internal. 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. 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 PI system has one Central Instance (CI) running at the server sappici, and one application instance (running at the server sappiapp1). Alerting is not available for unauthorized users, Right click and copy the link to share this comment. 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. You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. 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. 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. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). This publication got considerable public attention as 10KBLAZE. 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). In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. It is important to mention that the Simulation Mode applies to the registration action only. There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. While it is common and recommended by many resources to define this rule in a custom secinfo ACL as the last rule, from a security perspective it is not an optimal approach. The parameter is gw/logging, see note 910919. We solved it by defining the RFC on MS. 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. The tax system is running on the server taxserver. 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). About item #1, I will forward your suggestion to Development Support. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. Here, the Gateway is used for RFC/JCo connections to other systems. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. Part 4: prxyinfo ACL in detail 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. 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. In this case the Gateway Options must point to exactly this RFC Gateway host. Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. 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')). Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. For example: The SAP KBAs1850230and2075799might be helpful. The first letter of the rule can be either P (for Permit) or D (for Deny). Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. Program cpict4 is not permitted to be started. IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. 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. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. 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. This means that the sequence of the rules is very important, especially when using general definitions. TP is restricted to 64 non-Unicode characters for both secinfo and reginfo files. 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. Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. The gateway replaces this internally with the list of all application servers in the SAP system. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. The name of the registered program will be TAXSYS. Every attribute should be maintained as specific as possible. D prevents this program from being started. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Please note: The wildcard * is per se supported at the end of a string only. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. 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. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. 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). 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 Aber gewnscht ist, mssen die Zugriffskontrolllisten erstellt werden local rules should not be permitted a standalone RFC Gateway regards!
