It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. 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. The tax system is running on the server taxserver. Part 2: reginfo ACL in detail. RFC had issue in getting registered on DI. IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. Access to the ACL files must be restricted. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. 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. 2. The local gateway where the program is registered can always cancel the program. 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. Somit knnen keine externe Programme genutzt werden. 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. The wildcard * should be strongly avoided. This makes sure application servers must have a trust relation in order to take part of the internal server communication. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. HOST = servername, 10. 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. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. All subsequent rules are not even checked. 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. Part 6: RFC Gateway Logging 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. Giving more details is not possible, unfortunately, due to security reasons. 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. 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 internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. 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). Please note: SNC User ACL is not a feature of the RFC Gateway itself. 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. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. Part 4: prxyinfo ACL in detail. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. P TP=* USER=* USER-HOST=internal HOST=internal. The secinfo security file is used to prevent unauthorized launching of external programs. The related program alias also known as TP Name is used to register a program at the RFC Gateway. 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 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. 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. Part 8: OS command execution using sapxpg. 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. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. 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. Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. RFC had issue in getting registered on DI. Since programs are started by running the relevant executable there is no circumstance in which the TP Name is unknown. In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_SEC_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. 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. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. This is a list of host names that must comply with the rules above. 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. 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. Datenbankschicht: In der Datenbank, welche auf einem Datenbankserver liegt, werden alle Daten eines Unternehmens gesichert. The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. I think you have a typo. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. With this blogpost series i try to give a comprehensive explanation of the RFC Gateway Security: Part 1: General questions about the RFC Gateway and RFC Gateway security. 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. This order is not mandatory. This means the call of a program is always waiting for an answer before it times out. 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. 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. For example: you have changed to the rule related to the SLD_UC program, allowing a new server to communicate with it (you added the new server to the ACCESS option). 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. Please note: SNC System ACL is not a feature of the RFC Gateway itself. Examples of valid addresses are: Number (NO=): Number between 0 and 65535. The order of the remaining entries is of no importance. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Part 5: ACLs and the RFC Gateway security. The reginfo ACL contains rules related to Registered external RFC Servers. 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. 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. From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. 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. Help with the understanding of the RFC Gateway ACLs (Access Control Lists) and the Simulation Mode, in order to help prepare production systems to have these security features enabled without disruptions. The prxyinfo file is holding rules controlling which source systems (based on their hostname/ip-address) are allowed to talk to which destination systems (based on their hostname/ip-address) over the current RFC Gateway. 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. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. It is common to define this rule also in a custom reginfo file as the last rule. Very good post. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. In a pure Java system, one Gateway is sufficient for the whole system because the instances do not use RFC to communicate. Its location is defined by parameter gw/prxy_info. 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. 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. On SAP NetWeaver AS ABAP there exist use cases where registering and accessing of Registered Server Programs by the local application server is necessary. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. All programs started by hosts within the SAP system can be started on all hosts in the system. 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 seems to me that the parameter is gw/acl_file instead of ms/acl_file. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. If no access list is specified, the program can be used from any client. 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 . Danach wird die Queue neu berechnet. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. Part 4: prxyinfo ACL in detail. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). 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 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. Host Name (HOST=, ACCESS= and/or CANCEL=): The wildcard character * stands for any host name, *.sap.com for a domain, sapprod for host sapprod. This publication got considerable public attention as 10KBLAZE. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. 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. To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. 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. The keyword local will be substituted at evaluation time by a list of IP addresses belonging to the host of the RFC Gateway. Only the first matching rule is used (similarly to how a network firewall behaves). 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. Furthermore the means of some syntax and security checks have been changed or even fixed over time. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Add a Comment . Programs within the system are allowed to register. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. Part 3: secinfo ACL in detail this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. 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. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. Refer to the SAP Notes 2379350 and2575406 for the details. An example could be the integration of a TAX software. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. 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). The following syntax is valid for the secinfo file. This is defined in, how many Registered Server Programs with the same name can be registered. Each instance can have its own security files with its own rules. As separators you can use commas or spaces. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. P means that the program is permitted to be registered (the same as a line with the old syntax). 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. 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. Program foo is only allowed to be used by hosts from domain *.sap.com. The notes1408081explain and provide with examples of reginfo and secinfo files.

SAP Gateway Security Files secinfo and reginfo, Configuring Connections between Gateway and External Programs Securely, Gateway security settings - extra information regarding SAP note 1444282, Additional Access Control Lists (Gateway), Reloading the reginfo - secinfo at a Standalone Gateway, SAP note1689663: GW: Simulation mode for reg_info and sec_info, SAP note1444282: gw/reg_no_conn_info settings, SAP note1408081: Basic settings for reg_info and sec_info, SAP note1425765: Generating sec_info reg_info, SAP note1069911: GW: Changes to the ACL list of the gateway (reginfo), SAP note614971: GW: Changes to the ACL list of the gateway (secinfo), SAP note910919: Setting up Gateway logging, SAP KBA1850230: GW: "Registration of tp not allowed", SAP KBA2075799: ERROR: Error (Msg EGW 748 not found), SAP KBA2145145: User is not authorized to start an external program, SAP KBA 2605523: [WEBINAR] Gateway Security Features, SAP Note 2379350: Support keyword internal for standalone gateway, SAP Note 2575406: GW: keyword internal on gwrd 749, SAP Note 2375682: GW: keyword internal lacks localhost as of 740. ooohhh my god, (It could not have been more complicated -obviously the sequence of lines is important): "# This must always be the last rule on the file see SAP note 1408081" + next line content, is not included as comment within the default-delivered reginfo file or secinfo file (after installation) -, this would save a lot ofwasted life time, gw/acl_mode: ( looks like to enable/disable the complete gw-security config, but ). Sie knnen die Queue-Auswahl reduzieren. 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). This list is gathered from the Message Server every 5 minutes by the report RSMONGWY_SEND_NILIST. The RFC destination would look like: The secinfo files from the application instances are not relevant. As i suspect it should have been registered from Reginfo file rather than OS. Program cpict4 is allowed to be registered by any host. 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 first letter of the rule can be either P (for Permit) or D (for Deny). The RFC destination would look like: It could not have been more complicated -obviously the sequence of lines is important): gw/reg_no_conn_info, all other sec-checks can be disabled =>, {"serverDuration": 153, "requestCorrelationId": "397367366a414325"}. Part 5: Security considerations related to these ACLs. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. A combination of these mitigations should be considered in general. This is for clarity purposes. Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. Part 3: secinfo ACL in detail. 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. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted. P SOURCE=* DEST=*. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. For example: The SAP KBAs1850230and2075799might be helpful. 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. They are: The diagram below shows the workflow of how the RFC Gateway works with the security rules and the involved parameters, like the Simulation Mode. 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). Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. 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 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! If no cancel list is specified, any client can cancel the program. (any helpful wiki is very welcome, many thanks toIsaias Freitas). Its location is defined by parameter 'gw/reg_info'. File reginfo controls the registration of external programs in the gateway. Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. 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. For a RFC Gateway of AS Java or a stand-alone RFC Gateway this can be determined with the command-line tool gwmon by running the command gwmon nr= pf= then going to the menu by typing m and displaying the client table by typing 3. 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. 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. RFCs between RFC clients using JCo/NCo or Registered Server Programs and the AS ABAP are typically controlled on network level only. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. 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. The RFC Gateway can be seen as a communication middleware. 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. 1. other servers had communication problem with that DI. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. File reginfocontrols the registration of external programs in the gateway. Please make sure you have read part 1 4 of this series. Part 5: Security considerations related to these ACLs. This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. 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. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. As we learned in part 4 SAP introduced the following internal rule in the in the prxyinfo ACL: All other programs starting with cpict4 are allowed to be started (on every host and by every user). 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. The secinfo file has rules related to the start of programs by the local SAP instance. 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. This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. 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. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . 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). Part 8: OS command execution using sapxpg. 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. Alerting is not available for unauthorized users. 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. The other parts are not finished, yet. The first line of the reginfo/secinfo files must be # VERSION = 2. 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. Its functions are then used by the ABAP system on the same host. CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. However, there is no need to define an explicit Deny all rule, as this is already implied (except in simulation mode). From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. It is common to define this rule also in a custom reginfo file as the last rule. Its location is defined by parameter gw/sec_info. 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. Part 6: RFC Gateway Logging. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. 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. 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). The host with address 10.18.210.140 Gateway may be used by hosts from domain *.sap.com that the ``.
