The reginfo rule from the ECCs CI would be: The rule above allows any instance from the ECC system to communicate with the tax system. if the server is available again, this as error declared message is obsolete. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. Check the above mentioned SAP documentation about the particular of each version; 4)It is possible to enable the RFC Gateway logging in order to reproduce the issue. 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. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. 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). The local gateway where the program is registered always has access. Terms of use | From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. Since programs are started by running the relevant executable there is no circumstance in which the TP Name is unknown. Someone played in between on reginfo file. In production systems, generic rules should not be permitted. In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. If this addition is missing, any number of servers with the same ID are allowed to log on. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. 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. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. 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). You have a non-SAP tax system that needs to be integrated with SAP. Despite this, system interfaces are often left out when securing IT systems. This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. If USER-HOST is not specifed, the value * is accepted. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. 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. 1. other servers had communication problem with that DI. We solved it by defining the RFC on MS. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS). 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. This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). As separators you can use commas or spaces. In the gateway monitor (SMGW) choose Goto Logged On Clients , use the cursor to select the registered program, and choose Goto Logged On Clients Delete Client . 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. 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. 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. Part 3: secinfo ACL in detail. (any helpful wiki is very welcome, many thanks toIsaias Freitas). As such, it is an attractive target for hacker attacks and should receive corresponding protections. 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. Add a Comment this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. Part 3: secinfo ACL in detail. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. Part 5: ACLs and the RFC Gateway security. D prevents this program from being started. Hufig ist man verpflichtet eine Migration durchzufhren. Part 5: ACLs and the RFC Gateway security. This page contains information about the RFC Gateway ACLs (reginfo and secinfo files), the Simulation Mode, as well as the workflow showing how the RFC Gateway works with regards to the ACLs versus the Simulation Mode. This is an allow all rule. The RFC Gateway does not perform any additional security checks. Please make sure you have read part 1 4 of this series. Environment. Limiting access to this port would be one mitigation. 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. 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. 3. 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 reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. Changes to the reginfo rules are not immediately effective, even afterhaving reloaded the file (transaction SMGW, menu Goto -> Expert functions -> External security -> Reread / Read again). secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. Part 4: prxyinfo ACL in detail 2.20) is taken into account only if every comma-separated entry can be resolved into an IP address.

To control access from the client side too, you can define an access list for each entry. 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. Example Example 1: The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. 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. There may also be an ACL in place which controls access on application level. 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. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. Part 5: Security considerations related to these ACLs. What is important here is that the check is made on the basis of hosts and not at user level. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. Somit knnen keine externe Programme genutzt werden. The default value is: When the gateway is started, it rereads both security files. Please follow me to get a notification once i publish the next part of the series. A LINE with a HOST entry having multiple host names (e.g. It is common to define this rule also in a custom reginfo file as the last rule. 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. Part 8: OS command execution using sapxpg. Its location is defined by parameter gw/sec_info. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. RFC had issue in getting registered on DI. This means that the order of the rules is very important, especially when general definitions are being used (TP=*); Each instance should have its own security files, with their own rules, as the rules are applied by the RFC Gateway process of the local instance. (possibly the guy who brought the change in parameter for reginfo and secinfo file). A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. 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. 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. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. three months) is necessary to ensure the most precise data possible for the connections used. However, you still receive the "Access to registered program denied" / "return code 748" error. Part 3: secinfo ACL in detail In other words the same host running the ABAP system is also running the SAP IGS, for example the integrated IGS (as part of SAP NW AS ABAP) may be started on the application servers host during the start procedure of the ABAP system. If the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. In the following i will do the question and answer game to develop a basic understanding of the RFC Gateway, the RFC Gateway security and its related terms. 1. other servers had communication problem with that DI. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. 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. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. 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. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). 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. D prevents this program from being registered on the gateway. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. A rule defines. The related program alias also known as TP Name is used to register a program at the RFC Gateway. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. 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 If no cancel list is specified, any client can cancel the program. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. This could be defined in. The secinfo file has rules related to the start of programs by the local SAP instance. TP is a mandatory field in the secinfo and reginfo files. The syntax used in the reginfo, secinfo and prxyinfo changed over time. As we learned in part 4 SAP introduced the following internal rule in the in the prxyinfo ACL: Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. 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. Program cpict4 is not permitted to be started. 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. 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. P means that the program is permitted to be registered (the same as a line with the old syntax). This is because the rules used are from the Gateway process of the local instance. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. A custom allow rule has to be maintained on the proxying RFC Gateway only. 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. Furthermore the means of some syntax and security checks have been changed or even fixed over time. Part 7: Secure communication secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . Part 6: RFC Gateway Logging. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. This order is not mandatory. In a pure Java system, one Gateway is sufficient for the whole system because the instances do not use RFC to communicate. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. Only clients from the local application server are allowed to communicate with this registered program. In SAP NetWeaver Application Server Java: The SCS instance has a built-in RFC Gateway. In case you dont want to use the keyword, each instance would need a specific rule. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. File reginfocontrols the registration of external programs in the gateway. Check the secinfo and reginfo files. Part 2: reginfo ACL in detail. For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter. Part 2: reginfo ACL in detail. This publication got considerable public attention as 10KBLAZE. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. There are two different syntax versions that you can use (not together). It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. Please note: The wildcard * is per se supported at the end of a string only. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. The wildcard * should be strongly avoided. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. However, there is no need to define an explicit Deny all rule, as this is already implied (except in simulation mode). Hello Venkateshwar, thank you for your comment. Part 2: reginfo ACL in detail In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_REG_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. 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. 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. After reloading the file, it is necessary to de-register all registrations of the affected program, and re-register it again. Refer to the SAP Notes 2379350 and2575406 for the details. The name of the registered program will be TAXSYS. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Part 4: prxyinfo ACL in detail. 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. Its location is defined by parameter gw/reg_info. 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. Part 7: Secure communication 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). The Gateway uses the rules in the same order in which they are displayed in the file. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. Very good post. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. 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. 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). Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. 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. 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. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. It is common to define this rule also in a custom reginfo file as the last rule. The RFC Gateway hands over the request from the RFC client to the dispatcher which assigns it to a work process (AS ABAP) or to a server process (AS Java). Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. 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. 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. You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. Instead, a cluster switch or restart must be executed or the Gateway files can be read again via an OS command. 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. Every line corresponds one rule. There are various tools with different functions provided to administrators for working with security 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. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. 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. 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. To set up the recommended secure SAP Gateway configuration, proceed as follows:. In der Liste sichtbar und knnen auch wieder ausgewhlt werden, RED incorrect as the last rule parts.
