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=*`. IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. 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. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Hinweis: Whlen Sie ber den Button und nicht das Dropdown-Men Gewhren aus! Wechseln Sie dazu auf die gewnschte Registerkarte (im Beispiel ist das Universen), whlen Sie Verwalten --> Sicherheit auf oberster Ebene --> Alle Universen (je nach Registerkarte unterscheidet sich der letzte Punkt). 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). You can define the file path using profile parameters gw/sec_infoand gw/reg_info. The parameter is gw/logging, see note 910919. 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. In an ideal world each program alias of the relevant Registered Server Programs would be listed in a separate rule, even for registering program aliases from one of the hosts of internal. Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. We should pretend as if we would maintain the ACLs of a stand-alone RFC Gateway. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. Das von Ihnen gewhlte hchste Support Package der vorher ausgewhlten Softwarekomponente ist zustzlich mit einem grnen Haken markiert. This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. Program foo is only allowed to be used by hosts from domain *.sap.com. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. The RFC Gateway can be used to proxy requests to other RFC Gateways. 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. The other parts are not finished, yet. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. Maybe some security concerns regarding the one or the other scenario raised already in you head. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. 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. The subsequent blogs of will describe each individually. The wildcard * should be strongly avoided. 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. All of our custom rules should bee allow-rules. P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. 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. If the Gateway protections fall short, hacking it becomes childs play. Please note: SNC User ACL is not a feature of the RFC Gateway itself. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. An example could be the integration of a TAX software. Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. The solution is to stop the SLD program, and start it again (in other words, de-register the program, and re-register it). As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. Furthermore the means of some syntax and security checks have been changed or even fixed over time. So lets shine a light on security. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. The PI system has one Central Instance (CI) running at the server sappici, and one application instance (running at the server sappiapp1). 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. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. The Gateway is the technical component of the SAP server that manages the communication for all RFC-based functions. D prevents this program from being registered on the gateway. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. 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. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. . You have an RFC destination named TAX_SYSTEM. A custom allow rule has to be maintained on the proxying RFC Gateway only. 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. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. 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. Alerting is not available for unauthorized users. The secinfosecurity file is used to prevent unauthorized launching of external programs. 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. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. Please assist ASAP. 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. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. P means that the program is permitted to be registered (the same as a line with the old syntax). From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Copyright |
This publication got considerable public attention as 10KBLAZE. Hufig ist man verpflichtet eine Migration durchzufhren. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. For example: The SAP KBAs1850230and2075799might be helpful. You can define the file path using profile parameters gw/sec_info and gw/reg_info. (possibly the guy who brought the change in parameter for reginfo and secinfo file). The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. To set up the recommended secure SAP Gateway configuration, proceed as follows:. Part 2: reginfo ACL in detail File reginfo controls the registration of external programs in the gateway. 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. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. Checking the Security Configuration of SAP Gateway. Each instance can have its own security files with its own rules. In other words, the SAP instance would run an operating system level command. Of course the local application server is allowed access. 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. where ist the hint or wiki to configure a well runing gw-security ? This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. Haben Support Packages in der Queue Verbindungen zu Support Packages einer anderen Komponente (weitere Vorgngerbeziehung, erforderliches CRT) wird die Queue um weitere Support Packages erweitert, bis alle Vorgngerbeziehungen erfllt sind. Specifically, it helps create secure ACL files. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. 2.20) is taken into account only if every comma-separated entry can be resolved into an IP address. D prevents this program from being started. Check out our SAST SOLUTIONS website or send us an e-mail us at sast@akquinet.de. Part 7: Secure communication For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). File reginfocontrols the registration of external programs in the gateway. 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. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. The message server port which accepts registrations is defined by profile parameter rdisp/msserv_internal. The default configuration of an ASCS has no Gateway. 1. other servers had communication problem with that DI. A general secinfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): Only the (SAP level) user IDs BOB and JOHN can start this program, and they will be logged on to one of the instances from this SAP system. 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. 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. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). 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. 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. File reginfocontrols the registration of external programs in the gateway. 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. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. 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. Use host names instead of the IP address. 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. Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. Access attempts coming from a different domain will be rejected. Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. What is important here is that the check is made on the basis of hosts and not at user level. The Solution Manager (SolMan) system has only one instance, running at the host sapsmci. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). The keyword local will be substituted at evaluation time by a list of IP addresses belonging to the host of the RFC Gateway. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. 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. Part 5: ACLs and the RFC Gateway security. The Gateway uses the rules in the same order in which they are displayed in the file. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. Always document the changes in the ACL files. P SOURCE=* DEST=*. Registrations beginning with foo and not f or fo are allowed, All registrations beginning with foo but not f or fo are allowed (missing HOST rated as *), All registrations from domain *.sap.com are allowed. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. This means that the sequence of the rules is very important, especially when using general definitions. HOST = servername, 10. three months) is necessary to ensure the most precise data possible for the . The RFC Gateway does not perform any additional security checks. The secinfosecurity file is used to prevent unauthorized launching of external programs. 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. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. Es gibt folgende Grnde, die zum Abbruch dieses Schrittes fhren knnen: CANNOT_SKIP_ATTRIBUTE_RECORD: Die Attribute knnen in der OCS-Datei nicht gelesen werden. 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). Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. 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. 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. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. (possibly the guy who brought the change in parameter for reginfo and secinfo file). 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. 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. The wildcard * should not be used at all. To edit the security files,you have to use an editor at operating system level. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. The RFC Gateway is capable to start programs on the OS level. 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: Please note: If the AS ABAP system has more than one application servers and therefore also more than one RFC Gateways there may be scenarios in which the Registered Server Program is registered at one specific RFC Gateway only. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. 2. 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). As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. 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). Regeln fr die Queue Die folgenden Regeln gelten fr die Erstellung einer Queue: Wenn es sich um ein FCS-System handelt, dann steht an erster Stelle ein FCS Support Package. As i suspect it should have been registered from Reginfo file rather than OS. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. 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 . Thank you! 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 . If the TP name itself contains spaces, you have to use commas instead. Please pay special attention to this phase! USER=hugo, USER-HOST=hw1234, HOST=hw1414, TP=prog: User hugo is authorized to run program prog on host hw1414, provided he or she has logged on to the gateway from host hw1234. Its location is defined by parameter gw/sec_info. 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. Every attribute should be maintained as specific as possible. Then the file can be immediately activated by reloading the security files. Program cpict4 is allowed to be registered by any host. Somit knnen keine externe Programme genutzt werden. As we learned in part 4 SAP introduced the following internal rule in the in the prxyinfo ACL: Part 3: secinfo ACL in detail When using SNC to secure logon for RFC Clients or Registered Server Programs the so called SNC User ACL, also known as User Authentication, is introduced and must be maintained accordingly. Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. All programs started by hosts within the SAP system can be started on all hosts in the system. If no access list is specified, the program can be used from any client. if the server is available again, this as error declared message is obsolete. This publication got considerable public attention as 10KBLAZE. Please note: The wildcard * is per se supported at the end of a string only. Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. Visit SAP Support Portal's SAP Notes and KBA Search. In the slides of the talk SAP Gateway to Heaven for example a scenario is outlined in which a SAProuter installed on the same server as the RFC Gateway could be utilized to proxy a connection to local. The reginfo file has the following syntax. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. To control access from the client side too, you can define an access list for each entry. Part 8: OS command execution using sapxpg. This could be defined in. 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. Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. 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. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. Part 1: General questions about the RFC Gateway and RFC Gateway security. 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. This means the call of a program is always waiting for an answer before it times out. The tax system is running on the server taxserver. Sobald dieses Recht vergeben wurde, taucht die Registerkarte auch auf der CMC-Startseite wieder auf. secinfo: P TP=* USER=* USER-HOST=* HOST=*. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. The location of this ACL can be defined by parameter gw/acl_info. The first letter of the rule can be either P (for Permit) or D (for Deny). 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. Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. The syntax used in the reginfo, secinfo and prxyinfo changed over time. The default rule in prxyinfo ACL (as mentioned in part 4) is enabled if no custom ACL is defined. Somit knnen keine externe Programme genutzt werden. Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted. 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. 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 the previous parts we had a look at the different ACLs and the scenarios in which they are applied. This is because the rules used are from the Gateway process of the local instance. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. The RFC destination would look like: The secinfo files from the application instances are not relevant. It seems to me that the parameter is gw/acl_file instead of ms/acl_file. You can also control access to the registered programs and cancel registered programs. 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. 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. In case of TP Name this may not be applicable in some scenarios. Part 8: OS command execution using sapxpg. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. 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. There are various tools with different functions provided to administrators for working with security files. 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. Someone played in between on reginfo file. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. Legal Disclosure |
Part 2: reginfo ACL in detail. Additional ACLs are discussed at this WIKI page. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. This publication got considerable public attention as 10KBLAZE. 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 blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. RFC had issue in getting registered on DI.
