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. Please note: SNC User ACL is not a feature of the RFC Gateway itself. The tax system is running on the server taxserver. 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. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). Copyright |
Each instance can have its own security files with its own rules. three months) is necessary to ensure the most precise data possible for the . 3. 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. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. The RFC Gateway can be used to proxy requests to other RFC Gateways. This opensb the Gateway ACL Editor, where you can display the relevant files.. To enable system-internal communication, the files must contain the . As such, it is an attractive target for hacker attacks and should receive corresponding protections. RFC had issue in getting registered on DI. Visit SAP Support Portal's SAP Notes and KBA Search. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. As i suspect it should have been registered from Reginfo file rather than OS. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. To edit the security files,you have to use an editor at operating system level. Since this keyword is relaying on a kernel feature as well as an ABAP report it is not available in the internal RFC Gateway of SAP NW AS Java. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. In these cases the program alias is generated with a random string. Giving more details is not possible, unfortunately, due to security reasons. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. Its location is defined by parameter gw/sec_info. Part 6: RFC Gateway Logging. Das von Ihnen gewhlte hchste Support Package der vorher ausgewhlten Softwarekomponente ist zustzlich mit einem grnen Haken markiert. 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)). Here, the Gateway is used for RFC/JCo connections to other systems. Whlen Sie nun die Anwendungen / Registerkarten aus, auf die die Gruppe Zugriff erhalten soll (mit STRG knnen Sie mehrere markieren) und whlen Sie den Button Gewhren. The subsequent blogs of will describe each individually. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. Configuring Connections between SAP Gateway and External Programs Securely, SAP Gateway Security Files secinfo and reginfo, Setting Up Security Settings for External Programs. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. 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. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. 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. 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). In addition, the existing rules on the reginfo/secinfo file will be applied, even on Simulation Mode. Each line must be a complete rule (rules cannot be broken up over two or more lines). Part 4: prxyinfo ACL in detail. As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. If the option is missing, this is equivalent to HOST=*. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. secinfo: P TP=* USER=* USER-HOST=* HOST=*. Part 2: reginfo ACL in detail. The PI system has one Central Instance (CI) running at the server sappici, and one application instance (running at the server sappiapp1). In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. Hufig ist man verpflichtet eine Migration durchzufhren. 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. You can define the file path using profile parameters gw/sec_info and gw/reg_info. Program foo is only allowed to be used by hosts from domain *.sap.com. You have already reloaded the reginfo file. There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. 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. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. There is an SAP PI system that needs to communicate with the SLD. There are two different syntax versions that you can use (not together). DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. In production systems, generic rules should not be permitted. In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. (any helpful wiki is very welcome, many thanks toIsaias Freitas). 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 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). The RFC Gateway is capable to start programs on the OS level. Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. Every attribute should be maintained as specific as possible. The simulation mode is a feature which could help to initially create the ACLs. Part 5: ACLs and the RFC Gateway security. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. If the called program is not an RFC enabled program (compiled with the SAP RFC library) the call will time out, but the program is still left running on the OS level! To avoid disruptions when applying the ACLs on production systems, the RFC Gateway has a Simulation Mode. Please note: The wildcard * is per se supported at the end of a string only. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. All of our custom rules should bee allow-rules. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS). All programs started by hosts within the SAP system can be started on all hosts in the system. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo 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 SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. As i suspect it should have been registered from Reginfo file rather than OS. Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. 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! 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. There are other SAP notes that help to understand the syntax (refer to the Related notes section below). The first letter of the rule can begin with either P (permit) or D (deny). Evaluate the Gateway log files and create ACL rules. 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). 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 All subsequent rules are not even checked. Access attempts coming from a different domain will be rejected. Of course the local application server is allowed access. Save ACL files and restart the system to activate the parameters. It is important to mention that the Simulation Mode applies to the registration action only. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. File reginfo controls the registration of external programs in the gateway. 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 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. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. Part 4: prxyinfo ACL in detail If this addition is missing, any number of servers with the same ID are allowed to log on. So lets shine a light on security. This publication got considerable public attention as 10KBLAZE. 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. 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. Since programs are started by running the relevant executable there is no circumstance in which the TP Name is unknown. A combination of these mitigations should be considered in general. P SOURCE=* DEST=*. Use host names instead of the IP address. Its location is defined by parameter gw/reg_info. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. 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. As we learned in part 2 SAP introduced the following internal rule in the in the reginfo ACL: P TP=* HOST=internal,local ACCESS=internal,local CANCEL=internal,local. Part 8: OS command execution using sapxpg. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. 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. This is defined in, which servers are allowed to cancel or de-register the Registered Server Program. 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. Sobald dieses Recht vergeben wurde, taucht die Registerkarte auch auf der CMC-Startseite wieder auf. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. 1. other servers had communication problem with that DI. 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 RFC Gateway does not perform any additional security checks. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. The order of the remaining entries is of no importance. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . Somit knnen keine externe Programme genutzt werden. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. As we learned in part 4 SAP introduced the following internal rule in the in the prxyinfo ACL: Instead, a cluster switch or restart must be executed or the Gateway files can be read again via an OS command. 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. 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]. Access to this ports is typically restricted on network level. 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. However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). 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. 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 There are three places where we can find an RFC Gateway: The RFC Gateway is by default reachable via the services sapgw and sapgws which can be mapped to the ports 33 and 48. This means the call of a program is always waiting for an answer before it times out. You can also control access to the registered programs and cancel registered programs. This publication got considerable public attention as 10KBLAZE. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. D prevents this program from being registered on the gateway. The other parts are not finished, yet. This is an allow all rule. IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. Click more to access the full version on SAP for Me (Login . Example Example 1: 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). Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. In other words, the SAP instance would run an operating system level command. 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. 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). Now 1 RFC has started failing for program not registered. 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. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. 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. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). P TP=* USER=* USER-HOST=internal HOST=internal. 2. 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. The Gateway uses the rules in the same order in which they are displayed in the file. There are various tools with different functions provided to administrators for working with security files. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. 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 Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. To permit registered servers to be used by local application servers only, the file must contain the following entry. For this scenario a custom rule in the reginfo ACL would be necessary, e.g., P TP= HOST= ACCESS=internal,local CANCEL=internal,local,. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. three months) is necessary to ensure the most precise data possible for the connections used. 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. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. 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. (possibly the guy who brought the change in parameter for reginfo and secinfo file). Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. After the external program was registered, the ACCESS and CANCEL options will be followed as defined in the rule, if a rule existed. 1. other servers had communication problem with that DI. 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. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. If no access list is specified, the program can be used from any client. The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. 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. 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). 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. 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. Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. You have an RFC destination named TAX_SYSTEM. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. The wildcard * should be strongly avoided. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. P means that the program is permitted to be registered (the same as a line with the old syntax). However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. In case of TP Name this may not be applicable in some scenarios. 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. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. If USER-HOST is not specifed, the value * is accepted. At time of writing this can not be influenced by any profile parameter. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. The secinfo file has rules related to the start of programs by the local SAP instance. 3. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. 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. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. Part 5: ACLs and the RFC Gateway security. Part 7: Secure communication From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. 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. Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. 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. This is for clarity purposes. 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. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. 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). Environment. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo 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. Please make sure you have read at least part 1 of this series to be familiar with the basics of the RFC Gateway and the terms i use to describe things. If the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. Would you like more information on our SAST SUITE or would you like to find out more about ALL ROUND protection of your SAP systems? where ist the hint or wiki to configure a well runing gw-security ? 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. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. The secinfosecurity file is used to prevent unauthorized launching of external programs. Terms of use |
Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted. This list is gathered from the Message Server every 5 minutes by the report RSMONGWY_SEND_NILIST. 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.
