reginfo and secinfo location in sap

For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS). P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. With secinfo file this corresponds to the name of the program on the operating system level. Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. In case you dont want to use the keyword, each instance would need a specific rule. There is an SAP PI system that needs to communicate with the SLD. Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. However, you still receive the "Access to registered program denied" / "return code 748" error. Part 6: RFC Gateway Logging. 1. other servers had communication problem with that DI. The simulation mode is a feature which could help to initially create the ACLs. Fr die gewnschten Registerkarten "Gewhren" auswhlen. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. 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. Program foo is only allowed to be used by hosts from domain *.sap.com. This parameter will enable special settings that should be controlled in the configuration of reginfo file. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). If this addition is missing, any number of servers with the same ID are allowed to log on. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. 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. This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. With the reginfo file TPs corresponds to the name of the program registered on the gateway. 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. P SOURCE=* DEST=*. 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. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Part 7: Secure communication In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. This is defined in, how many Registered Server Programs with the same name can be registered. The following syntax is valid for the secinfo file. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. This publication got considerable public attention as 10KBLAZE. 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. You dont need to define a deny all rule at the end, as this is already implicit (if there is no matching Permit rule, and the RFC Gateway already checked all the rules, the result will be Deny except when the Simulation Mode is active, see below). It seems to me that the parameter is gw/acl_file instead of ms/acl_file. 3. For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. Check the availability and use SM59 to ping all TP IDs.In the case of an SCS/ASCS instance, it cannot be reloaded via SMGW. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. Access to this ports is typically restricted on network level. Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. *. Then the file can be immediately activated by reloading the security files. There are two different syntax versions that you can use (not together). Part 5: ACLs and the RFC Gateway security. All programs started by hosts within the SAP system can be started on all hosts in the system. What is important here is that the check is made on the basis of hosts and not at user level. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. 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. If the Gateway protections fall short, hacking it becomes childs play. The reginfo file has the following syntax. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. Part 5: ACLs and the RFC Gateway security. Part 4: prxyinfo ACL in detail. Part 3: secinfo ACL in detail. For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. The wildcard * should not be used at all. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo This publication got considerable public attention as 10KBLAZE. Besttigen Sie den auftauchenden Hinweis und vergeben Sie fr die gewnschten Gruppen zumindest das folgende Recht: Allgemein --> Allgemein --> Objekte Anzeigen. The first letter of the rule can begin with either P (permit) or D (deny). We should pretend as if we would maintain the ACLs of a stand-alone RFC Gateway. An example could be the integration of a TAX software. Please assist ASAP. 1. other servers had communication problem with that DI. This would cause "odd behaviors" with regards to the particular RFC destination. Add a Comment Please follow me to get a notification once i publish the next part of the series. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. 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. Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. 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. The Gateway is a central communication component of an SAP system. You have an RFC destination named TAX_SYSTEM. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. 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 This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* 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. This means that the sequence of the rules is very important, especially when using general definitions. Please note: The wildcard * is per se supported at the end of a string only. 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. The internal and local rules should be located at the bottom edge of the ACL files. 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. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. If the TP name itself contains spaces, you have to use commas instead. Here are some examples: At the application server #1, with hostname appsrv1: At the application server #2, with hostname appsrv2: The SAP KBA2145145has a video illustrating how the secinfo rules work. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. After the external program was registered, the ACCESS and CANCEL options will be followed as defined in the rule, if a rule existed. A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. This is because the rules used are from the Gateway process of the local instance. In other words, the SAP instance would run an operating system level command. 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! Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. 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. In the slides of the talk SAP Gateway to Heaven for example a scenario is outlined in which a SAProuter installed on the same server as the RFC Gateway could be utilized to proxy a connection to local. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. Part 5: Security considerations related to these ACLs. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. (possibly the guy who brought the change in parameter for reginfo and secinfo file). 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. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. This way, each instance will use the locally available tax system. . To assign the new settings to the registered programs too (if they have been changed at all), the servers must first be deregistered and then registered again. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. The RFC Gateway can be seen as a communication middleware. Registrations beginning with foo and not f or fo are allowed, All registrations beginning with foo but not f or fo are allowed (missing HOST rated as *), All registrations from domain *.sap.com are allowed. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. Part 8: OS command execution using sapxpg. 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 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). Configuring Connections between SAP Gateway and External Programs Securely, SAP Gateway Security Files secinfo and reginfo, Setting Up Security Settings for External Programs. 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. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. 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. 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. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. Part 3: secinfo ACL in detail. From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. A rule defines. Legal Disclosure | Please note: SNC User ACL is not a feature of the RFC Gateway itself. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. Once you have completed the change, you can reload the files without having to restart the gateway. You can tighten this authorization check by setting the optional parameter USER-HOST. File reginfo controls the registration of external programs in the gateway. 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. For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter.
