Part 2: reginfo ACL in detail. 1408081 - Basic settings for reg_info and sec_info 1702229 - Precalculation: Specify Program ID in sec_info and reg_info. This is defined in, how many Registered Server Programs with the same name can be registered. At time of writing this can not be influenced by any profile parameter. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. HOST = servername, 10. 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). The parameter is gw/logging, see note 910919. TP is restricted to 64 non-Unicode characters for both secinfo and reginfo files. 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). 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. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. 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. (any helpful wiki is very welcome, many thanks toIsaias Freitas). Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. 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. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Reread . 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. Visit SAP Support Portal's SAP Notes and KBA Search. Additional ACLs are discussed at this WIKI page. A rule defines. As we learned in part 4 SAP introduced the following internal rule in the in the prxyinfo ACL: Part 8: OS command execution using sapxpg. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. 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. 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. After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). P SOURCE=* DEST=*. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. 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. 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. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. You have a non-SAP tax system that needs to be integrated with SAP. Read more. Despite this, system interfaces are often left out when securing IT systems. There may also be an ACL in place which controls access on application level. 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. After the external program was registered, the ACCESS and CANCEL options will be followed as defined in the rule, if a rule existed. Someone played in between on reginfo file. Program foo is only allowed to be used by hosts from domain *.sap.com. Example Example 1: Please assist me how this change fixed it ? 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. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. Part 4: prxyinfo ACL in detail. 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. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. 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. 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. Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. Only clients from domain *.sap.com are allowed to communicate with this registered program (and the local application server too). The secinfo security file is used to prevent unauthorized launching of external programs. 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. To set up the recommended secure SAP Gateway configuration, proceed as follows:. 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. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. The solution is to stop the SLD program, and start it again (in other words, de-register the program, and re-register it). Copyright | 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. Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. This means that if the file is changed and the new entries immediately activated, the servers already logged on will still have the old attributes. 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. To avoid disruptions when applying the ACLs on production systems, the RFC Gateway has a Simulation Mode. 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). When using SNC to secure RFC destinations on AS ABAP the so called SNC System ACL, also known as System Authentication, is introduced and must be maintained accordingly. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. With this rule applied any RFC enabled program on any of the servers covered by the keyword internal is able to register itself at the RFC Gateway independent from which user started the corresponding executable on OS level (again refer to 10KBLAZE). 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. (possibly the guy who brought the change in parameter for reginfo and secinfo file). Every attribute should be maintained as specific as possible. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. The RFC Gateway can be used to proxy requests to other RFC Gateways. 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. Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. The name of the registered program will be TAXSYS. Program hugo is allowed to be started on every local host and by every user. What is important here is that the check is made on the basis of hosts and not at user level. If the TP name itself contains spaces, you have to use commas instead. 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. If the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. 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). Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. Somit knnen keine externe Programme genutzt werden. Part 5: ACLs and the RFC Gateway security. 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)). Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. Please assist ASAP. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. Click more to access the full version on SAP for Me (Login . Part 6: RFC Gateway Logging. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. 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. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. TP is a mandatory field in the secinfo and reginfo files. Legal Disclosure | This would cause "odd behaviors" with regards to the particular RFC destination. As such, it is an attractive target for hacker attacks and should receive corresponding protections. 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). Check out our SAST SOLUTIONS website or send us an e-mail us at sast@akquinet.de. 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 follow me to get a notification once i publish the next part of the series. 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. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. The network service that, in turn, manages the RFC communication is provided by the RFC Gateway. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. 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 . Hinweis: Whlen Sie ber den Button und nicht das Dropdown-Men Gewhren aus! The RFC Gateway does not perform any additional security checks. Giving more details is not possible, unfortunately, due to security reasons. For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. Once you have completed the change, you can reload the files without having to restart the gateway. 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). In these cases the program alias is generated with a random string. 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. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. This is for clarity purposes. The PI system has one Central Instance (CI) running at the server sappici, and one application instance (running at the server sappiapp1). Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. so for me it should only be a warning/info-message. 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. 2.20) is taken into account only if every comma-separated entry can be resolved into an IP address. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. Ergebnis Sie haben eine Queue definiert. 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. The RFC Gateway can be seen as a communication middleware. 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). 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. 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. To edit the security files,you have to use an editor at operating system level. All other programs from host 10.18.210.140 are not allowed to be registered. Privacy | 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. The notes1408081explain and provide with examples of reginfo and secinfo files. The keyword internal will be substituted at evaluation time by a list of hostnames of application servers in status ACTIVE which is periodically sent to all connected RFC Gateways. Then the file can be immediately activated by reloading the security files. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. three months) is necessary to ensure the most precise data possible for the connections used. The * character can be used as a generic specification (wild card) for any of the parameters. Every line corresponds one rule. Danach wird die Queue neu berechnet. 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. Part 4: prxyinfo ACL in detail. In production systems, generic rules should not be permitted. After reloading the file, it is necessary to de-register all registrations of the affected program, and re-register it again. 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. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. 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. 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 . Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. Hufig ist man verpflichtet eine Migration durchzufhren. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. Add a Comment In other words, the SAP instance would run an operating system level command. Evaluate the Gateway log files and create ACL rules. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). Thank you! 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. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. 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 following syntax is valid for the secinfo file. In other words, the SAP instance would run an operating system level command. All subsequent rules are not even checked. NUMA steht fr Non-Uniform Memory Access und beschreibt eine Computer-Speicher-Architektur fr Multiprozessorsysteme, bei der jeder Prozessor ber einen eigenen, lokalen physischen Speicher verfgt, aber anderen Prozessoren ber einen gemeinsamen Adressraum direkten Zugriff darauf gewhrt (Distributed Shared Memory). 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. The Gateway is a central communication component of an SAP system. The secinfo file has rules related to the start of programs by the local SAP instance. Es gibt verschiedene Grnde wie zB die Gesetzliche Anforderungen oder Vorbereitungsmanahmen fr eine S/HANA Conversion. Somit knnen keine externe Programme genutzt werden. The wildcard * should not be used at all. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. It is common to define this rule also in a custom reginfo file as the last rule. If no cancel list is specified, any client can cancel the program. Part 7: Secure communication Its location is defined by parameter gw/prxy_info. If USER-HOST is not specifed, the value * is accepted. 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. 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 Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. Trademark. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. The reginfo ACL contains rules related to Registered external RFC Servers. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. The tax system is running on the server taxserver. Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. 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. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. Now 1 RFC has started failing for program not registered. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. *. Another mitigation would be to switch the internal server communication to TLS using a so-called systemPKI by setting the profile parameter system/secure_communication = ON. In addition, note that the system checks the case of all keywords and only takes keywords into account if they are written in upper case. The subsequent blogs of will describe each individually. About item #1, I will forward your suggestion to Development Support. Falls es in der Queue fehlt, kann diese nicht definiert werden. This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section).
