reginfo and secinfo location in sap

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. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. 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. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. Part 8: OS command execution using sapxpg. 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 tax system is running on the server taxserver. Trademark. 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. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. 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. Somit knnen keine externe Programme genutzt werden. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. This means the call of a program is always waiting for an answer before it times out. HOST = servername, 10. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. 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. Die Datei kann vermutlich nicht zum Lesen geffnet werden, da sie zwischenzeitlich gelscht wurde, oder die Berechtigungen auf Betriebssystemebene unzureichend sind. In production systems, generic rules should not be permitted. All other programs from host 10.18.210.140 are not allowed to be registered. 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 RFC library provides functions for closing registered programs. 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! From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. 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. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. The first letter of the rule can begin with either P (permit) or D (deny). Please note: The wildcard * is per se supported at the end of a string only. This would cause "odd behaviors" with regards to the particular RFC destination. Danach wird die Queue neu berechnet. CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. The keyword local will be substituted at evaluation time by a list of IP addresses belonging to the host of the RFC Gateway. 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 Gateway is the technical component of the SAP server that manages the communication for all RFC-based functions. 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. How to guard your SAP Gateway against unauthorized calls, Study shows SAP systems especially prone to insider attacks, Visit our Pathlock Germany website https://pathlock.com/de/, Visit our Pathlock Blog: https://pathlock.com/de/blog/, SAST SOLUTIONS: Now member of Pathlock Group. All other programs starting with cpict4 are allowed to be started (on every host and by every user). In this case the Gateway Options must point to exactly this RFC Gateway host. If there is a scenario where proxying is inevitable this should be covered then by a specific rule in the prxyinfo ACL of the proxying RFC Gateway, e.g.,: P SOURCE= DEST=internal,local. The local gateway where the program is registered can always cancel the program. Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. 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 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. 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. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. 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). How can I quickly migrate SAP custom code to S/4HANA? Privacy | If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. Examples of valid addresses are: Number (NO=): Number between 0 and 65535. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. 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. 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 The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. If the Gateway protections fall short, hacking it becomes childs play. Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. This order is not mandatory. 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. In some cases any application server of the same system may also 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. The RFC Gateway does not perform any additional security checks. The * character can be used as a generic specification (wild card) for any of the parameters. Its location is defined by parameter gw/reg_info. Refer to the SAP Notes 2379350 and2575406 for the details. If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. 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. The secinfo file has rules related to the start of programs by the local SAP instance. With secinfo file this corresponds to the name of the program on the operating system level. 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). Only clients from the local application server are allowed to communicate with this registered program. P SOURCE=* DEST=*. 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. 3. Part 4: prxyinfo ACL in detail. Each instance can have its own security files with its own rules. It is common to define this rule also in a custom reginfo file as the last rule. 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. 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. IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. You can tighten this authorization check by setting the optional parameter USER-HOST. so for me it should only be a warning/info-message. Most of the cases this is the troublemaker (!) They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. D prevents this program from being registered on the gateway. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. Someone played in between on reginfo file. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. What is important here is that the check is made on the basis of hosts and not at user level. 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)). Checking the Security Configuration of SAP Gateway. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. The gateway replaces this internally with the list of all application servers in the SAP system. The reginfo ACL contains rules related to Registered external RFC Servers. Falls es in der Queue fehlt, kann diese nicht definiert werden. The first letter of the rule can be either P (for Permit) or D (for Deny). 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. 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. Maybe some security concerns regarding the one or the other scenario raised already in you head. Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. Part 1: General questions about the RFC Gateway and RFC Gateway security. Part 3: secinfo ACL in detail. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. 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. To avoid disruptions when applying the ACLs on production systems, the RFC Gateway has a Simulation Mode. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. Part 3: secinfo ACL in detail To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. Limiting access to this port would be one mitigation. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). This publication got considerable public attention as 10KBLAZE. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. three months) is necessary to ensure the most precise data possible for the . On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. Part 2: reginfo ACL in detail. 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. 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. Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. There may also be an ACL in place which controls access on application level. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. Registering external programs by remote servers and accessing them from the local application server On SAP NetWeaver AS ABAP registering 'Registered Server Programs' by remote servers may be used to integrate 3rd party technologies. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. 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. Please note: SNC User ACL is not a feature of the RFC Gateway itself. Evaluate the Gateway log files and create ACL rules. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. Part 6: RFC Gateway Logging. Hello Venkateshwar, thank you for your comment. 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. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. Please assist me how this change fixed it ? You have a non-SAP tax system that needs to be integrated with SAP. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. Part 7: Secure communication Configuring Connections between SAP Gateway and External Programs Securely, SAP Gateway Security Files secinfo and reginfo, Setting Up Security Settings for External Programs. 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. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. The default configuration of an ASCS has no Gateway. Its location is defined by parameter gw/sec_info. If no access list is specified, the program can be used from any client. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. Part 5: ACLs and the RFC Gateway security. Besttigen Sie den auftauchenden Hinweis und vergeben Sie fr die gewnschten Gruppen zumindest das folgende Recht: Allgemein --> Allgemein --> Objekte Anzeigen. Programs within the system are allowed to register. We can identify these use cases by going to transaction SMGW -> Goto -> Logged on Clients and looking for programs listed with System Type = Registered Server and Gateway Host set to any IP address or hostname not belonging to any application server of the same system. 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 1. other servers had communication problem with that DI. 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. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. This diagram shows all use-cases except `Proxy to other RFC Gateways. Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. No error is returned, but the number of cancelled programs is zero. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. It also enables communication between work or server processes of SAP NetWeaver AS and external programs. 2.20) is taken into account only if every comma-separated entry can be resolved into an 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. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. Somit knnen keine externe Programme genutzt werden. This makes sure application servers must have a trust relation in order to take part of the internal server communication. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. Legal Disclosure | In order to figure out the reason that the RFC Gateway is not allowing the registered program, following some basics steps that should be managed during the creation of the rules: 1)The rules in the files are read by the RFC Gateway from the TOP to the BOTTOM hence it is important to check the previous rules in order to check if the specific problem does not fit some previously rule. The RFC destination would look like: The secinfo files from the application instances are not relevant. To permit registered servers to be used by local application servers only, the file must contain the following entry. The parameter is gw/logging, see note 910919. 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. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. Part 5: Security considerations related to these ACLs. 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. It is important to mention that the Simulation Mode applies to the registration action only. Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. In SAP NetWeaver Application Server Java: The SCS instance has a built-in RFC Gateway. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. This is an allow all rule. Ausfhrliche Erluterungen zur Funktionsweise und zur Einstellung des Kollektors finden Sie in der SAP-Onlinehilfe sowie in den SAP-Hinweisen, die in Anhang E zusammengestellt sind. Terms of use | 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. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. You have already reloaded the reginfo file. Here, the Gateway is used for RFC/JCo connections to other systems. Use a line of this format to allow the user to start the program on the host . Access attempts coming from a different domain will be rejected. 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. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. Additional ACLs are discussed at this WIKI page. 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. Despite this, system interfaces are often left out when securing IT systems. In case you dont want to use the keyword, each instance would need a specific rule. This parameter will allow you to reproduce the RFC Gateway access and see the TP and HOST that the access is using hence create the rules in the reginfo or secinfo file; 5)The rules defined in the reginfo or secinfo file can be reviewed in colored syntactic correctness. Every line corresponds one rule. 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). This ACL is applied on the ABAP layer and is maintained in transaction SNC0. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. There is an SAP PI system that needs to communicate with the SLD. It is common to define this rule also in a custom reginfo file as the last rule. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. 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. Its functions are then used by the ABAP system on the same host. You have an RFC destination named TAX_SYSTEM. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. This is a list of host names that must comply with the rules above. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. 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. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. Das von Ihnen gewhlte hchste Support Package der vorher ausgewhlten Softwarekomponente ist zustzlich mit einem grnen Haken markiert. 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. We should pretend as if we would maintain the ACLs of a stand-alone RFC Gateway. 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. if the server is available again, this as error declared message is obsolete. The reginfo file has the following syntax. In case the files are maintained, the value of this parameter is irrelevant; and with parmgw/reg_no_conn_info, all other sec-checks can be disabled =>SAP note1444282, obviously this parm default is set to 1 ( if not set in profile file ) in kernel-773, I wasted a whole day unsuccessfully trying to configure the (GW-Sec) in a new system, sorry for my bad mood.
