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. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. 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. Save ACL files and restart the system to activate the parameters. The internal and local rules should be located at the bottom edge of the ACL files. In other words, the SAP instance would run an operating system level command. RFC had issue in getting registered on DI. This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. There are two different syntax versions that you can use (not together). Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. Please note: SNC User ACL is not a feature of the RFC Gateway itself. 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. After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. The solution is to stop the SLD program, and start it again (in other words, de-register the program, and re-register it). In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. 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. 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. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. Copyright | secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. 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). Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. Maybe some security concerns regarding the one or the other scenario raised already in you head. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. You can also control access to the registered programs and cancel registered programs. Click more to access the full version on SAP for Me (Login . The secinfo security file is used to prevent unauthorized launching of external programs. As such, it is an attractive target for hacker attacks and should receive corresponding protections. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. 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. If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. Please assist ASAP. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. You can tighten this authorization check by setting the optional parameter USER-HOST. 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. Only clients from domain *.sap.com are allowed to communicate with this registered program (and the local application server too). Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. 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. It seems to me that the parameter is gw/acl_file instead of ms/acl_file. Access to the ACL files must be restricted. The first line of the reginfo/secinfo files must be # VERSION = 2. The first letter of the rule can begin with either P (permit) or D (deny). In case you dont want to use the keyword, each instance would need a specific rule. 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. Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. Specifically, it helps create secure ACL files. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. 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. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. The name of the registered program will be TAXSYS. Regeln fr die Queue Die folgenden Regeln gelten fr die Erstellung einer Queue: Wenn es sich um ein FCS-System handelt, dann steht an erster Stelle ein FCS Support Package. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. 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). Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. File reginfocontrols the registration of external programs in the gateway. In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. The RFC Gateway can be seen as a communication middleware. Part 4: prxyinfo ACL in detail. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: So lets shine a light on security. 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. To prevent the list of application servers from tampering we have to take care which servers are allowed to register themselves at the Message Server as an application server. Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. 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). BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . Part 8: OS command execution using sapxpg. 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. No error is returned, but the number of cancelled programs is zero. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). 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. Ergebnis Sie haben eine Queue definiert. This means that the sequence of the rules is very important, especially when using general definitions. This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. 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. If you want to use this syntax, the whole file must be structured accordingly and the first line must contain the entry #VERSION=2 (written precisely in this format). 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. This is because the rules used are from the Gateway process of the local instance. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. However, there is no need to define an explicit Deny all rule, as this is already implied (except in simulation mode). 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. Additional ACLs are discussed at this WIKI page. Part 3: secinfo ACL in detail. 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. 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.
