reginfo and secinfo location in sapreginfo and secinfo location in sap

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. 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. In diesem Blog-Beitrag werden zwei von SAP empfohlene Vorgehensweisen zur Erstellung der secinfo und reginfo Dateien aufgefhrt mit denen die Security Ihres SAP Gateways verstrkt wird und wie der Generator dabei hilft. A rule defines. 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). Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted. There are various tools with different functions provided to administrators for working with security files. 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. Again 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. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. After reloading the file, it is necessary to de-register all registrations of the affected program, and re-register it again. Please assist me how this change fixed it ? 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. RFC had issue in getting registered on DI. D prevents this program from being registered on the gateway. Part 8: OS command execution using sapxpg. Part 5: Security considerations related to these ACLs. The first letter of the rule can begin with either P (permit) or D (deny). But also in some cases the RFC Gateway itself may 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. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. 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. 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. 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. The message server port which accepts registrations is defined by profile parameter rdisp/msserv_internal. The following steps usually need to be done manually to secure an SAP Gateway: Our SAST Interface Management module in the SAST SUITE provides support in hardening the SAP Gateway. 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. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. Check the secinfo and reginfo files. Most of the cases this is the troublemaker (!) Add a Comment In these cases the program alias is generated with a random string. 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. The reginfo ACL contains rules related to Registered external RFC Servers. 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. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. 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. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. The RFC Gateway hands over the request from the RFC client to the dispatcher which assigns it to a work process (AS ABAP) or to a server process (AS Java). so for me it should only be a warning/info-message. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. If the option is missing, this is equivalent to HOST=*. We should pretend as if we would maintain the ACLs of a stand-alone RFC Gateway. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. 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. 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. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. 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. In case of TP Name this may not be applicable in some scenarios. RFCs between RFC clients using JCo/NCo or Registered Server Programs and the AS ABAP are typically controlled on network level only. Here, the Gateway is used for RFC/JCo connections to other systems. Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. 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. The Solution Manager (SolMan) system has only one instance, running at the host sapsmci. Successful and rejected registrations, and calls from registered programs can be ascertained using Gateway Logging with indicator S. Any error lines are put in the trace file dev_rd, and are not read in. File reginfocontrols the registration of external programs in the gateway. Only the first matching rule is used (similarly to how a network firewall behaves). Maybe some security concerns regarding the one or the other scenario raised already in you head. 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. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. Part 2: reginfo ACL in detail. Click more to access the full version on SAP for Me (Login . 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. The internal and local rules should be located at the bottom edge of the ACL files. This publication got considerable public attention as 10KBLAZE. To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. In diesem Blog-Beitrag werden zwei von SAP empfohlene Vorgehensweisen zur Erstellung der secinfo und reginfo Dateien aufgefhrt mit denen die Security Ihres SAP Gateways verstrkt wird und wie der Generator dabei hilft. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. There are other SAP notes that help to understand the syntax (refer to the Related notes section below). This is an allow all rule. The RFC Gateway allows external RFC Server programs (also known as Registered Server or Registered Server Program) to register to itself and allows RFC clients to consume the functions offered by these programs. Part 1: General questions about the RFC Gateway and RFC Gateway security. A combination of these mitigations should be considered in general. Read more. The prxyinfo file is holding rules controlling which source systems (based on their hostname/ip-address) are allowed to talk to which destination systems (based on their hostname/ip-address) over the current RFC Gateway. Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. The RFC Gateway does not perform any additional security checks. Now 1 RFC has started failing for program not registered. Part 4: prxyinfo ACL in detail. 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. 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. Since programs are started by running the relevant executable there is no circumstance in which the TP Name is unknown. Besttigen Sie den auftauchenden Hinweis und vergeben Sie fr die gewnschten Gruppen zumindest das folgende Recht: Allgemein --> Allgemein --> Objekte Anzeigen. 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). If no access list is specified, the program can be used from any client. The secinfosecurity file is used to prevent unauthorized launching of external programs. Someone played in between on reginfo file. 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. In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. This is because the rules used are from the Gateway process of the local instance. Part 4: prxyinfo ACL in detail. While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. Checking the Security Configuration of SAP Gateway. 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. The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. Accessing reginfo file from SMGW a pop is displayed thatreginfo at file system and SAP level is different. Part 5: ACLs and the RFC Gateway security. The name of the registered program will be TAXSYS. 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 . Datenbankschicht: In der Datenbank, welche auf einem Datenbankserver liegt, werden alle Daten eines Unternehmens gesichert. The related program alias also known as TP Name is used to register a program at the RFC Gateway. This list is gathered from the Message Server every 5 minutes by the report RSMONGWY_SEND_NILIST. 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). 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. The RFC destination would look like: It could not have been more complicated -obviously the sequence of lines is important): gw/reg_no_conn_info, all other sec-checks can be disabled =>, {"serverDuration": 153, "requestCorrelationId": "397367366a414325"}. This would cause "odd behaviors" with regards to the particular RFC destination. Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. Its location is defined by parameter gw/prxy_info. The location of this ACL can be defined by parameter gw/acl_info. When using SNC to secure logon for RFC Clients or Registered Server Programs the so called SNC User ACL, also known as User Authentication, is introduced and must be maintained accordingly. The RFC Gateway can be seen as a communication middleware. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Terms of use | if the server is available again, this as error declared message is obsolete. The other parts are not finished, yet. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. The Gateway is a central communication component of an SAP system. 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. You have an RFC destination named TAX_SYSTEM. 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)). 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. 3. This could be defined in. The reginfo file has the following syntax. In an ideal world each program alias of the relevant Registered Server Programs would be listed in a separate rule, even for registering program aliases from one of the hosts of internal. Furthermore the means of some syntax and security checks have been changed or even fixed over time. 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. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. 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')). There may also be an ACL in place which controls access on application level. 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. Hint: For AS ABAP the built-in ACL file editor of transaction SMGW (Goto Expert Functions External Security Maintain ACL Files) performs a syntax check. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. 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. 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. E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* The default rule in prxyinfo ACL (as mentioned in part 4) is enabled if no custom ACL is defined. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. If other SAP systems also need to communicate with it, using the ECC system, the rule need to be adjusted, adding the hostnames from the other systems to the ACCESS option. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. 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). The Gateway is the technical component of the SAP server that manages the communication for all RFC-based functions. You can define the file path using profile parameters gw/sec_info and gw/reg_info. Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. 3. secinfo: P TP=* USER=* USER-HOST=* HOST=*. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. 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. File reginfo controls the registration of external programs in the gateway. To permit registered servers to be used by local application servers only, the file must contain the following entry. Part 5: ACLs and the RFC Gateway security. 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 RFC library provides functions for closing registered programs. In other words, the SAP instance would run an operating system level command. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. To edit the security files,you have to use an editor at operating system level. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. Part 3: secinfo ACL in detail. You have a non-SAP tax system that needs to be integrated with SAP. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). The RFC Gateway can be used to proxy requests to other RFC Gateways. 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). Part 6: RFC Gateway Logging. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system.The secinfo file has rules related to the start of programs by the local SAP instance. No error is returned, but the number of cancelled programs is zero. Limiting access to this port would be one mitigation. All subsequent rules are not checked at all. Part 7: Secure communication The solution is to stop the SLD program, and start it again (in other words, de-register the program, and re-register it). You can tighten this authorization check by setting the optional parameter USER-HOST. Please note: SNC User ACL is not a feature of the RFC Gateway itself. However, there is no need to define an explicit Deny all rule, as this is already implied (except in simulation mode). This means the call of a program is always waiting for an answer before it times out. As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: Trademark. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. Program hugo is allowed to be started on every local host and by every user. Part 2: reginfo ACL in detail. For AS ABAP the ACLs should be maintained using the built-in ACL file editor of transaction SMGW (Goto Expert Functions External Security Maintain ACL Files). For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. Use host names instead of the IP address. The very first line of the reginfo/secinfo file must be "#VERSION=2"; Each line must be a complete rule (you cannot break the rule into two or more lines); The RFC Gateway will apply the rules in the same order as they appear in the file, and only the first matching rule will be used (similar to the behavior of a network firewall). Privacy | 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. 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. 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. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. Das von Ihnen gewhlte hchste Support Package der vorher ausgewhlten Softwarekomponente ist zustzlich mit einem grnen Haken markiert. The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. Fr die gewnschten Registerkarten "Gewhren" auswhlen. If the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. A custom allow rule has to be maintained on the proxying RFC Gateway only. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. 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). Hufig ist man verpflichtet eine Migration durchzufhren. HOST = servername, 10. Please assist ASAP. Every line corresponds one rule. The order of the remaining entries is of no importance. Part 8: OS command execution using sapxpg. 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. 2040644 provides more details on that ist jedoch ein sehr groer Arbeitsaufwand..
