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! Access to this ports is typically restricted on network level. 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. To permit registered servers to be used by local application servers only, the file must contain the following entry. An example could be the integration of a TAX software. RFCs between RFC clients using JCo/NCo or Registered Server Programs and the AS ABAP are typically controlled on network level only. Evaluate the Gateway log files and create ACL rules. 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. Specifically, it helps create secure ACL files. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. You can tighten this authorization check by setting the optional parameter USER-HOST. 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 USER-HOST is not specifed, the value * is accepted. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. Its location is defined by parameter 'gw/reg_info'. If the option is missing, this is equivalent to HOST=*. The first letter of the rule can begin with either P (permit) or D (deny). Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. 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. 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. 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. 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. Fr die gewnschten Registerkarten "Gewhren" auswhlen. 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. Most of the cases this is the troublemaker (!) Please make sure you have read part 1 4 of this series. You can define the file path using profile parameters gw/sec_info and gw/reg_info. Very good post. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. 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. At time of writing this can not be influenced by any profile parameter. Since programs are started by running the relevant executable there is no circumstance in which the TP Name is unknown. 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. Giving more details is not possible, unfortunately, due to security reasons. Here, the Gateway is used for RFC/JCo connections to other systems. In SAP NetWeaver Application Server Java: The SCS instance has a built-in RFC Gateway. 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. In summary, if the Simulation Mode is deactivated (parameter gw/sim_mode = 0; default value), the last implicit rule from the RFC Gateway will be Deny all as mentioned above, at the RFC Gateway ACLs (reginfo and secinfo) section. The following syntax is valid for the secinfo file. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. 3. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . Datenbankschicht: In der Datenbank, welche auf einem Datenbankserver liegt, werden alle Daten eines Unternehmens gesichert. Please note: SNC System ACL is not a feature of the RFC Gateway itself. 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 As i suspect it should have been registered from Reginfo file rather than OS. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. Please assist me how this change fixed it ? The reginfo file is holding rules controlling which remote servers (based on their hostname/ip-address) are allowed to either register, access or cancel which Registered Server Programs (based on their program alias (also known as TP name)). Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. 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. 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. 3. 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"}. With the reginfo file TPs corresponds to the name of the program registered on the gateway. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. Of course the local application server is allowed access. This could be defined in. Somit knnen keine externe Programme genutzt werden. Die Datei kann vermutlich nicht zum Lesen geffnet werden, da sie zwischenzeitlich gelscht wurde, oder die Berechtigungen auf Betriebssystemebene unzureichend sind. Access to the ACL files must be restricted. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo 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 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 Gateway uses the rules in the same order in which they are displayed in the file. 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. 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. For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. All programs started by hosts within the SAP system can be started on all hosts in the system. The default rule in prxyinfo ACL (as mentioned in part 4) is enabled if no custom ACL is defined. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. Part 8: OS command execution using sapxpg. 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. There are various tools with different functions provided to administrators for working with security files. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Please note: SNC User ACL is not a feature of the RFC Gateway itself. The RFC library provides functions for closing registered programs. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. P SOURCE=* DEST=*. However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. 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. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. It registers itself with the program alias IGS. at the RFC Gateway of the same application server. 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). Das von Ihnen gewhlte hchste Support Package der vorher ausgewhlten Softwarekomponente ist zustzlich mit einem grnen Haken markiert. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. 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. TP is a mandatory field in the secinfo and reginfo files. 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. For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter. The subsequent blogs of will describe each individually. The secinfo file from the CI would look like the below: In case you dont want to use the keywords local and internal, youll have to manually specify the hostnames. The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. See the examples in the note1592493; 2)It is possible to change the rules in the files and reload its configuration without restart the RFC Gateway: open the transaction SMGW -> Goto -> expert functions -> external security -> reload However, in such situation, it is mandatory to de-register the registered program involved and reregister it again because programs already registered will continue following the old rules; 3)The rules in the secinfo and reginfo file do not always use the same syntax, it depends of the VERSION defined in the file. Part 1: General questions about the RFC Gateway and RFC Gateway security. Despite this, system interfaces are often left out when securing IT systems. Limiting access to this port would be one mitigation. You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. 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. 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. It is common to define this rule also in a custom reginfo file as the last rule. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. The name of the registered program will be TAXSYS. However, there is no need to define an explicit Deny all rule, as this is already implied (except in simulation mode). 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. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Part 5: ACLs and the RFC Gateway security Its functions are then used by the ABAP system on the same host. Host Name (HOST=, ACCESS= and/or CANCEL=): The wildcard character * stands for any host name, *.sap.com for a domain, sapprod for host sapprod. In addition, the RFC Gateway logging (see the SAP note910919) can be used to log that an external program was registered, but no Permit rule existed. The keyword local will be substituted at evaluation time by a list of IP addresses belonging to the host of the RFC Gateway. RFC had issue in getting registered on DI. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. 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. Part 3: secinfo ACL in detail. Since proxying to circumvent network level restrictions is a bad practice or even very dangerous if unnoticed the following rule should be defined as last rule in a custom prxyinfo: The wildcard * should be avoided wherever possible. As we learned in part 4 SAP introduced the following internal rule in the in the prxyinfo ACL: Visit SAP Support Portal's SAP Notes and KBA Search. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. As such, it is an attractive target for hacker attacks and should receive corresponding protections. Save ACL files and restart the system to activate the parameters. Only the first matching rule is used (similarly to how a network firewall behaves). Once you have completed the change, you can reload the files without having to restart the gateway. 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. 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. You have already reloaded the reginfo file. Each line must be a complete rule (rules cannot be broken up over two or more lines). Its location is defined by parameter gw/reg_info. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. 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. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. Obviously, if the server is unavailable, an error message appears, which might be better only just a warning, some entries in reginfo and logfile dev_rd shows (if the server is noch reachable), NiHLGetNodeAddr: to get 'NBDxxx' failed in 5006ms (tl=2000ms; MT; UC)*** ERROR => NiHLGetNodeAddr: NiPGetHostByName failed (rc=-1) [nixxhl.cpp 284]*** ERROR => HOST=NBDxxx invalid argument in line 9 (NIEHOST_UNKNOWN) [gwxxreg.c 2897]. ber das Dropdown-Men regeln Sie, ob und wie weit Benutzer der Gruppe, die Sie aktuell bearbeiten, selbst CMC-Registerkartenkonfigurationen an anderen Gruppen / Benutzern vornehmen knnen! As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. 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). Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. 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. 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. If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. Part 6: RFC Gateway Logging In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. This would cause "odd behaviors" with regards to the particular RFC destination. 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. For example: The SAP KBAs1850230and2075799might be helpful. 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. 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. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. 2.20) is taken into account only if every comma-separated entry can be resolved into an IP address. 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. I think you have a typo. A LINE with a HOST entry having multiple host names (e.g. This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). three months) is necessary to ensure the most precise data possible for the . Wir untersttzen Sie gerne bei Ihrer Entscheidungen. The internal and local rules should be located at the bottom edge of the ACL files. You have a non-SAP tax system that needs to be integrated with SAP. Somit knnen keine externe Programme genutzt werden. Please assist ASAP. 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. A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. It also enables communication between work or server processes of SAP NetWeaver AS and external programs. Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. The RFC Gateway does not perform any additional security checks. You have configured the SLD at the Java-stack of the SolMan system, using the RFC Gateway of the SolMans ABAP-stack. Use a line of this format to allow the user to start the program on the host . 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 solution is to stop the SLD program, and start it again (in other words, de-register the program, and re-register it). Access attempts coming from a different domain will be rejected. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. Someone played in between on reginfo file. Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. Thank you! The related program alias also known as TP Name is used to register a program at the RFC Gateway. Danach wird die Queue neu berechnet. Refer to the SAP Notes 2379350 and2575406 for the details. 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). If no cancel list is specified, any client can cancel the program. It is common to define this rule also in a custom reginfo file as the last rule. There may also be an ACL in place which controls access on application level. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. Legal Disclosure |
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 secinfo security file is used to prevent unauthorized launching of external programs. 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). This is for clarity purposes. The reginfo file has the following syntax. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . For this scenario a custom rule in the reginfo ACL would be necessary, e.g., P TP= HOST= ACCESS=internal,local CANCEL=internal,local,. Part 5: ACLs and the RFC Gateway security. To set up the recommended secure SAP Gateway configuration, proceed as follows:. File reginfo controls the registration of external programs in the gateway. Hinweis: Whlen Sie ber den Button und nicht das Dropdown-Men Gewhren aus! You can define the file path using profile parameters gw/sec_infoand gw/reg_info. If no access list is specified, the program can be used from any client. Then the file can be immediately activated by reloading the security files. Part 3: secinfo ACL in detail 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). Program hugo is allowed to be started on every local host and by every user. Example Example 1: File reginfocontrols the registration of external programs in the gateway. 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. where ist the hint or wiki to configure a well runing gw-security ? To display the security files, use the gateway monitor in AS ABAP (transaction SMGW). 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. However, you still receive the "Access to registered program denied" / "return code 748" error. 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). , a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must contain the following values: TP Name used!
