reginfo and secinfo location in sap

Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. Part 2: reginfo ACL in detail. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). The secinfo file has rules related to the start of programs by the local SAP instance. This publication got considerable public attention as 10KBLAZE. This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. 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). Visit SAP Support Portal's SAP Notes and KBA Search. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. If no cancel list is specified, any client can cancel the program. 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. 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. 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. IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. 3. 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. Additional ACLs are discussed at this WIKI page. 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). The wildcard * should not be used at all. Part 3: secinfo ACL in detail. ABAP SAP Basis Release as from 7.40 . You have already reloaded the reginfo file. After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). As i suspect it should have been registered from Reginfo file rather than OS. 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. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. This way, each instance will use the locally available tax system. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. The Stand-alone RFC Gateway: As a dedicated RFC Gateway serving for various RFC clients or as an additional component which may be used to extend a SAP NW AS ABAP or AS Java system. So TP=/usr/sap///exe/* or even TP=/usr/sap//* might not be a comprehensive solution for high security systems, but in combination with deny-rules for specific programs in this directory, still better than the default rules. 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). You can define the file path using profile parameters gw/sec_infoand gw/reg_info. where ist the hint or wiki to configure a well runing gw-security ? Part 3: secinfo ACL in detail Access to this ports is typically restricted on network level. The reginfo file has the following syntax. Example Example 1: All subsequent rules are not checked at all. Part 8: OS command execution using sapxpg. This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. 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. 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. 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. The Gateway is the technical component of the SAP server that manages the communication for all RFC-based functions. This publication got considerable public attention as 10KBLAZE. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. 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. The tax system is running on the server taxserver. Hinweis: Whlen Sie ber den Button und nicht das Dropdown-Men Gewhren aus! Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. At time of writing this can not be influenced by any profile parameter. Save ACL files and restart the system to activate the parameters. Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. 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 location of this ACL can be defined by parameter gw/acl_info. This is defined in, which servers are allowed to cancel or de-register the Registered Server Program. 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 P TP=* USER=* USER-HOST=internal HOST=internal. In this case the Gateway Options must point to exactly this RFC Gateway host. 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. It is common to define this rule also in a custom reginfo file as the last rule. Limiting access to this port would be one mitigation. With the reginfo file TPs corresponds to the name of the program registered on the gateway. 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. 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. As such, it is an attractive target for hacker attacks and should receive corresponding protections. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. No error is returned, but the number of cancelled programs is zero. CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. 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). It registers itself with the program alias IGS. at the RFC Gateway of the same application server. This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. Refer to the SAP Notes 2379350 and2575406 for the details. 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. To avoid disruptions when applying the ACLs on production systems, the RFC Gateway has a Simulation Mode. 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. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. This is for clarity purposes. 1. other servers had communication problem with that DI. 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). A rule defines. 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. Of course the local application server is allowed access. The secinfosecurity file is used to prevent unauthorized launching of external programs. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. Hello Venkateshwar, thank you for your comment. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. 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). 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. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. The simulation mode is a feature which could help to initially create the ACLs. Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. You have configured the SLD at the Java-stack of the SolMan system, using the RFC Gateway of the SolMans ABAP-stack. Part 5: Security considerations related to these ACLs. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. Part 2: reginfo ACL in detail. Only clients from the local application server are allowed to communicate with this registered program. so for me it should only be a warning/info-message. Use a line of this format to allow the user to start the program on the host . Part 1: General questions about the RFC Gateway and RFC Gateway security. 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 reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. Default values can be determined from the aggregated Gateway logging and used to assemble control data, and subsequently leverage the control data content for further use. You must keep precisely to the syntax of the files, which is described below. In production systems, generic rules should not be permitted. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. Part 2: reginfo ACL in detail The subsequent blogs of will describe each individually. Each instance can have its own security files with its own rules. You have an RFC destination named TAX_SYSTEM. Specifically, it helps create secure 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). Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted. This opensb the Gateway ACL Editor, where you can display the relevant files.. To enable system-internal communication, the files must contain the . 1408081 - Basic settings for reg_info and sec_info 1702229 - Precalculation: Specify Program ID in sec_info and reg_info. P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. A combination of these mitigations should be considered in general. 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 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. Most of the cases this is the troublemaker (!) There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. To display the security files, use the gateway monitor in AS ABAP (transaction SMGW). The RFC library provides functions for closing registered programs. Please pay special attention to this phase! Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. For example: The SAP KBAs1850230and2075799might be helpful. This could be defined in. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. Depending on the settings of the reginfo ACL a malicious user could also misuse this permissions to start a program which registers itself on the local RFC Gateway, e.g.,: Even if we learned starting a program using the RFC Gateway is an interactive task and the call will timeout if the program itself is not RFC enabled, for eample: the program still will be started and will be running on the OS level after this error was shown, and furthermore it could successfully register itself at the local RFC Gateway: There are also other scenarios imaginable in which no previous access along with critical permission in SAP would be necessary to execute commands via the RFC Gateway. 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). 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. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. To mitigate this we should look if it is generated using a fixed prefix and use this as a pattern with an ending wildcard in order to reduce the effective values, e.g., TP=Trex__*, which would still be better than TP=*`. 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 . this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. Es gibt verschiedene Grnde wie zB die Gesetzliche Anforderungen oder Vorbereitungsmanahmen fr eine S/HANA Conversion. About item #1, I will forward your suggestion to Development Support. 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. Part 7: Secure communication What is important here is that the check is made on the basis of hosts and not at user level. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Part 8: OS command execution using sapxpg. The RFC Gateway does not perform any additional security checks. As separators you can use commas or spaces. The secinfo security file is used to prevent unauthorized launching of external programs. 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). This makes sure application servers must have a trust relation in order to take part of the internal server communication. Part 4: prxyinfo ACL in detail. This list is gathered from the Message Server every 5 minutes by the report RSMONGWY_SEND_NILIST. 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. Falls es in der Queue fehlt, kann diese nicht definiert werden. Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. The related program alias also known as TP Name is used to register a program at the RFC Gateway. There are other SAP notes that help to understand the syntax (refer to the Related notes section below). From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. There is an SAP PI system that needs to communicate with the SLD. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. 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). 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 Please note: The wildcard * is per se supported at the end of a string only. RFCs between RFC clients using JCo/NCo or Registered Server Programs and the AS ABAP are typically controlled on network level only. Read more. 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. About this page This is a preview of a SAP Knowledge Base Article. This means that the sequence of the rules is very important, especially when using general definitions. 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? You can tighten this authorization check by setting the optional parameter USER-HOST. Part 3: secinfo ACL in detail. You can define the file path using profile parameters gw/sec_info and gw/reg_info. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). About the second comment and the error messages, those are messages related to DNS lookup.I believe that these are raised as errors because they have occurred during the parsing of the reginfo file. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. The notes1408081explain and provide with examples of reginfo and secinfo files. Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. Host Name (HOST=, ACCESS= and/or CANCEL=): The wildcard character * stands for any host name, *.sap.com for a domain, sapprod for host sapprod. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. This is because the rules used are from the Gateway process of the local instance. The solution is to stop the SLD program, and start it again (in other words, de-register the program, and re-register it). Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. 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. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Reread . 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. However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. Click more to access the full version on SAP for Me (Login . In SAP NetWeaver Application Server ABAP: Every Application Server has a built-in RFC Gateway. Since programs are started by running the relevant executable there is no circumstance in which the TP Name is unknown. All of our custom rules should bee allow-rules. Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. This order is not mandatory. Part 7: Secure communication For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS). Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. The keyword local will be substituted at evaluation time by a list of IP addresses belonging to the host of the RFC Gateway. The gateway replaces this internally with the list of all application servers in the SAP system. In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. 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. I think you have a typo. Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. 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. However, you still receive the "Access to registered program denied" / "return code 748" error. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. Part 5: ACLs and the RFC Gateway security. 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. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. . Terms of use | The RFC Gateway can be seen as a communication middleware. Make sure that they are set as per the Notes: Note 1425765 - Generating sec_info reg_info Note 1947412 - MDM Memory increase and RFC connection error The local gateway where the program is registered always has access. It is common to define this rule also in a custom reginfo file as the last rule. 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. Part 4: prxyinfo ACL in detail 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. 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. 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. Hufig ist man verpflichtet eine Migration durchzufhren.
