reginfo and secinfo location in sap

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). You have an RFC destination named TAX_SYSTEM. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. This section contains information about the RFC Gateway ACLs, and examples of landscapes and rules.The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. Every attribute should be maintained as specific as possible. Part 8: OS command execution using sapxpg. The name of the registered program will be TAXSYS. In this case the Gateway Options must point to exactly this RFC Gateway host. Part 4: prxyinfo ACL in detail 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. Only clients from the local application server are allowed to communicate with this registered program. About item #1, I will forward your suggestion to Development Support. You have a non-SAP tax system that needs to be integrated with SAP. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. 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. 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). On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. In SAP NetWeaver Application Server ABAP: Every Application Server has a built-in RFC Gateway. The simulation mode is a feature which could help to initially create the ACLs. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. RFC had issue in getting registered on DI. The wild card character * stands for any number of characters; the entry * therefore means no limitation, fo* stands for all names beginning with fo; foo stands precisely for the name foo. 1. other servers had communication problem with that DI. Privacy | To avoid disruptions when applying the ACLs on production systems, the RFC Gateway has a Simulation Mode. 3. Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. Access to the ACL files must be restricted. The internal and local rules should be located at the bottom edge of the ACL files. The message server port which accepts registrations is defined by profile parameter rdisp/msserv_internal. (any helpful wiki is very welcome, many thanks toIsaias Freitas). Part 1: General questions about the RFC Gateway and RFC Gateway security. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. 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. RFCs between two SAP NetWeaver AS ABAP systems are typically controlled on network level only. 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 parameter is gw/logging, see note 910919. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_REG_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. With secinfo file this corresponds to the name of the program on the operating system level. A custom allow rule has to be maintained on the proxying RFC Gateway only. For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter. Part 8: OS command execution using sapxpg. If this addition is missing, any number of servers with the same ID are allowed to log on. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. Die Datei kann vermutlich nicht zum Lesen geffnet werden, da sie zwischenzeitlich gelscht wurde, oder die Berechtigungen auf Betriebssystemebene unzureichend sind. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. This publication got considerable public attention as 10KBLAZE. Part 7: Secure communication There is an SAP PI system that needs to communicate with the SLD. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. This is an allow all rule. 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. The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. Part 4: prxyinfo ACL in detail. 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. Its location is defined by parameter 'gw/reg_info'. (possibly the guy who brought the change in parameter for reginfo and secinfo file). 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. 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. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. In case of TP Name this may not be applicable in some scenarios. 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 syntax used in the reginfo, secinfo and prxyinfo changed over time. 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. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. 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. This is defined in, how many Registered Server Programs with the same name can be registered. Would you like more information on our SAST SUITE or would you like to find out more about ALL ROUND protection of your SAP systems? if the server is available again, this as error declared message is obsolete. 2. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. 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. 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. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. Evaluate the Gateway log files and create ACL rules. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. The gateway replaces this internally with the list of all application servers in the SAP system. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. 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. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. Use host names instead of the IP address. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. Part 3: secinfo ACL in detail. 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. It is important to mention that the Simulation Mode applies to the registration action only. Part 3: secinfo ACL in detail. 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.
