If the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. 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. 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). 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. 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. Only clients from the local application server are allowed to communicate with this registered program. The secinfo file has rules related to the start of programs by the local SAP instance. 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. 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. How can I quickly migrate SAP custom code to S/4HANA? 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. 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. Ergebnis Sie haben eine Queue definiert. Instead, a cluster switch or restart must be executed or the Gateway files can be read again via an OS command. Thank you! There are various tools with different functions provided to administrators for working with security files. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. 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). Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. Examples of valid addresses are: Number (NO=): Number between 0 and 65535. The format of the first line is #VERSION=2, all further lines are structured as follows: Here the line starting with P or D, followed by a space or a TAB, has the following meaning: P means that the program is permitted to be started (the same as a line with the old syntax). In this case the Gateway Options must point to exactly this RFC Gateway host. 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. With this rule applied you should properly secure access to the OS (e.g., verify if all existing OS users are indeed necessary, SSH with public key instead of user+pw). 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. 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. A LINE with a HOST entry having multiple host names (e.g. Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. 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. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. 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')). When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. Part 3: secinfo ACL in detail. Its location is defined by parameter gw/sec_info. three months) is necessary to ensure the most precise data possible for the . P SOURCE=* DEST=*. This order is not mandatory. Part 5: ACLs and the RFC Gateway security. RFC had issue in getting registered on DI. Please make sure you have read at least part 1 of this series to be familiar with the basics of the RFC Gateway and the terms i use to describe things. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Reread . 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. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. Please note: SNC System ACL is not a feature of the RFC Gateway itself. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. The network service that, in turn, manages the RFC communication is provided by the RFC Gateway. Part 3: secinfo ACL in detail. 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. (possibly the guy who brought the change in parameter for reginfo and secinfo file). The RFC library provides functions for closing registered programs. The other parts are not finished, yet. Legal Disclosure |
There is an SAP PI system that needs to communicate with the SLD. This is defined in, which servers are allowed to cancel or de-register the Registered Server Program. This is for clarity purposes. 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. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. In addition, the existing rules on the reginfo/secinfo file will be applied, even on Simulation Mode. 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 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. 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. 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. RFC had issue in getting registered on DI. 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). If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. File reginfocontrols the registration of external programs in the gateway. Danach wird die Queue neu berechnet. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. The name of the registered program will be TAXSYS. Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. In other words, the SAP instance would run an operating system level command. 2. 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. We solved it by defining the RFC on MS. Part 4: prxyinfo ACL in detail 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. Part 5: Security considerations related to these ACLs. The following syntax is valid for the secinfo file. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. The syntax used in the reginfo, secinfo and prxyinfo changed over time. 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! Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. It is common and recommended by many resources to define the following rule in a custom prxyinfo ACL: With this, all requests from the local system, as well as all application servers of the same system, will be proxied by the RFC Gateway to any destination or end point. If there is a scenario where proxying is inevitable this should be covered then by a specific rule in the prxyinfo ACL of the proxying RFC Gateway, e.g.,: P SOURCE= DEST=internal,local. 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! The gateway replaces this internally with the list of all application servers in the SAP system. Please assist ASAP. (any helpful wiki is very welcome, many thanks toIsaias Freitas). Access to the ACL files must be restricted. Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. Please note: The wildcard * is per se supported at the end of a string only. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS).Before jumping to the ACLs themselves, here are a few general tips: A general reginfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): Usually, ACCESS is a list with at least all SAP servers from this SAP system. This could be defined in. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. TP is restricted to 64 non-Unicode characters for both secinfo and reginfo files. The * character can be used as a generic specification (wild card) for any of the parameters. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. It registers itself with the program alias IGS. at the RFC Gateway of the same application server. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. The RFC Gateway does not perform any additional security checks. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. Evaluate the Gateway log files and create ACL rules. 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. Part 5: ACLs and the RFC Gateway security. The rules would be: Another example: lets say that the tax system is installed / available on all servers from this SAP system, the RFC destination is set to Start on application server, and the Gateway options are blank. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. The default rule in prxyinfo ACL (as mentioned in part 4) is enabled if no custom ACL is defined. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. 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. 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). 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. Giving more details is not possible, unfortunately, due to security reasons. The RFC Gateway is capable to start programs on the OS level. We can identify these use cases by going to transaction SMGW -> Goto -> Logged on Clients and looking for lines with System Type = Registered Server and Gateway Host = 127.0.0.1 (in some cases this may be any other IP address or hostname of any application server of the same system). As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: The secinfo security file is used to prevent unauthorized launching of external programs. 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. The RFC Gateway does not perform any additional security checks. 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. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. 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. (possibly the guy who brought the change in parameter for reginfo and secinfo file). 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 ). 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 . The RFC Gateway can be seen as a communication middleware. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. As separators you can use commas or spaces. 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. If no cancel list is specified, any client can cancel the program. This is because the rules used are from the Gateway process of the local instance. 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. A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. Part 8: OS command execution using sapxpg. Program hugo is allowed to be started on every local host and by every user. Example Example 1: 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. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. *. File reginfocontrols the registration of external programs in the gateway. Every line corresponds one rule. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. Most of the cases this is the troublemaker (!) E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* To edit the security files,you have to use an editor at operating system level. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. This parameter will enable special settings that should be controlled in the configuration of reginfo file. This way, each instance will use the locally available tax system. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. 1. other servers had communication problem with that DI. In case you dont want to use the keyword, each instance would need a specific rule. 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. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. 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. 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 internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. To permit registered servers to be used by local application servers only, the file must contain the following entry. 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. 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. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. 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. 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. You must keep precisely to the syntax of the files, which is described below. Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. 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. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. 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. It also enables communication between work or server processes of SAP NetWeaver AS and external programs. 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 You have configured the SLD at the Java-stack of the SolMan system, using the RFC Gateway of the SolMans ABAP-stack. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. 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. 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]. 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. 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.
