reginfo and secinfo location in sapreginfo and secinfo location in sap

There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. 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. Legal Disclosure | 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. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. 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')). Trademark. To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. 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. The secinfosecurity file is used to prevent unauthorized launching of external programs. Sobald dieses Recht vergeben wurde, taucht die Registerkarte auch auf der CMC-Startseite wieder auf. Every line corresponds one rule. It seems to me that the parameter is gw/acl_file instead of ms/acl_file. Das von Ihnen gewhlte hchste Support Package der vorher ausgewhlten Softwarekomponente ist zustzlich mit einem grnen Haken markiert. To set up the recommended secure SAP Gateway configuration, proceed as follows:. D prevents this program from being started. Part 6: RFC Gateway Logging. For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter. 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). Part 3: secinfo ACL in detail. In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. It is common to define this rule also in a custom reginfo file as the last rule. RFC had issue in getting registered on DI. The first letter of the rule can be either P (for Permit) or D (for Deny). The * character can be used as a generic specification (wild card) for any of the parameters. 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. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered 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 . Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. 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. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. Part 5: ACLs and the RFC Gateway security. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. The Gateway is a central communication component of an SAP system. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. If the option is missing, this is equivalent to HOST=*. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. 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. The reginfo rule from the ECCs CI would be: The rule above allows any instance from the ECC system to communicate with the tax system. In other words, the SAP instance would run an operating system level command. 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. At time of writing this can not be influenced by any profile parameter. 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. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. 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. 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). Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. If the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. Of course the local application server is allowed access. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . ABAP SAP Basis Release as from 7.40 . Besttigen Sie den auftauchenden Hinweis und vergeben Sie fr die gewnschten Gruppen zumindest das folgende Recht: Allgemein --> Allgemein --> Objekte Anzeigen. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. 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. The RFC library provides functions for closing registered programs. The local gateway where the program is registered can always cancel the program. so for me it should only be a warning/info-message. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. 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). However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. Program hugo is allowed to be started on every local host and by every user. 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. 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. 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 To edit the security files,you have to use an editor at operating system level. The message server port which accepts registrations is defined by profile parameter rdisp/msserv_internal. Part 8: OS command execution using sapxpg. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. Access to this ports is typically restricted on network level. 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. 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. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. Check out our SAST SOLUTIONS website or send us an e-mail us at sast@akquinet.de. The default rule in prxyinfo ACL (as mentioned in part 4) is enabled if no custom ACL is defined. Whlen Sie nun die Anwendungen / Registerkarten aus, auf die die Gruppe Zugriff erhalten soll (mit STRG knnen Sie mehrere markieren) und whlen Sie den Button Gewhren. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. File reginfocontrols the registration of external programs in the gateway. 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. The network service that, in turn, manages the RFC communication is provided by the RFC Gateway. This would cause "odd behaviors" with regards to the particular RFC destination. The reginfo ACL contains rules related to Registered external RFC Servers. 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. 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. Part 2: reginfo ACL in detail. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. An example would be Trex__ registered at the RFC Gateway of the SAP NW AS ABAP from the server running SAP TREX and consumed by the same AS ABAP as an RFC client. Sie knnen die Queue-Auswahl reduzieren. . 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). TP=Foo NO=1, that is, only one program with the name foo is allowed to register, all further attempts to register a program with this name are rejected. Program cpict4 is not permitted to be started. Based on the original Gateway log files in the system, default values can be determined and generated for the ACL files directly after the evaluation of the data found. 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. Part 4: prxyinfo ACL in detail. 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. 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. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. 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. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. RFC had issue in getting registered on DI. 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). If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. if the server is available again, this as error declared message is obsolete. 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. Someone played in between on reginfo file. 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. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. Evaluate the Gateway log files and create ACL rules. This makes sure application servers must have a trust relation in order to take part of the internal server communication. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. 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. This is a list of host names that must comply with the rules above. Access attempts coming from a different domain will be rejected. D prevents this program from being registered on the gateway. This is because the rules used are from the Gateway process of the local instance. (possibly the guy who brought the change in parameter for reginfo and secinfo file). Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . Hinweis: Whlen Sie ber den Button und nicht das Dropdown-Men Gewhren aus! A combination of these mitigations should be considered in general. However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Part 2: reginfo ACL in detail. 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 zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. 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). Part 5: ACLs and the RFC Gateway security Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. 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. Haben Support Packages in der Queue Verbindungen zu Support Packages einer anderen Komponente (weitere Vorgngerbeziehung, erforderliches CRT) wird die Queue um weitere Support Packages erweitert, bis alle Vorgngerbeziehungen erfllt sind. 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. Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. 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 Program foo is only allowed to be used by hosts from domain *.sap.com. 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. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. The secinfo file has rules related to the start of programs by the local SAP instance. 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. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. 2.20) is taken into account only if every comma-separated entry can be resolved into an IP address. 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. Thank you! Wir untersttzen Sie gerne bei Ihrer Entscheidungen. Part 2: reginfo ACL in detail. Part 7: Secure communication 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. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. You must keep precisely to the syntax of the files, which is described below. 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. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. Each instance can have its own security files with its own rules. The subsequent blogs of will describe each individually. (any helpful wiki is very welcome, many thanks toIsaias Freitas). For example: you have changed to the rule related to the SLD_UC program, allowing a new server to communicate with it (you added the new server to the ACCESS option). Part 8: OS command execution using sapxpg. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. Most of the cases this is the troublemaker (!) 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. 1. other servers had communication problem with that DI. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. You have a non-SAP tax system that needs to be integrated with SAP. We made a change in the location of Reginfo and Secinfo file location we moved it to SYS directory and updated the profile parameter accordingly (instance profile). Specifically, it helps create secure ACL files. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. 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. With secinfo file this corresponds to the name of the program on the operating system level. You can define the file path using profile parameters gw/sec_info and gw/reg_info. 3. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. For this scenario a custom rule in the reginfo ACL would be necessary, e.g., P TP= HOST= ACCESS=internal,local CANCEL=internal,local,. HOST = servername, 10. three months) is necessary to ensure the most precise data possible for the connections used. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. The parameter is gw/logging, see note 910919. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. To mitigate this we should look if it is generated using a fixed prefix and use this as a pattern with an ending wildcard in order to reduce the effective values, e.g., TP=Trex__*, which would still be better than TP=*`. Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. 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. The location of this ACL can be defined by parameter gw/acl_info. 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. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. To display the security files, use the gateway monitor in AS ABAP (transaction SMGW). P TP=* USER=* USER-HOST=internal HOST=internal. Examples of valid addresses are: Number (NO=): Number between 0 and 65535. 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. Part 4: prxyinfo ACL in detail. Add a Comment 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). 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. Copyright | With the reginfo file TPs corresponds to the name of the program registered on the gateway. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. Die Datei kann vermutlich nicht zum Lesen geffnet werden, da sie zwischenzeitlich gelscht wurde, oder die Berechtigungen auf Betriebssystemebene unzureichend sind. This opensb the Gateway ACL Editor, where you can display the relevant files.. To enable system-internal communication, the files must contain the . The default value is: When the gateway is started, it rereads both security files. Danach wird die Queue neu berechnet. In addition to proper network separation, access to all message server ports can be controlled on network level by the ACL file specified by profile parameter ms/acl_file or more specific to the internal port by the ACL file specified by profile parameter ms/acl_file_int. This means that the sequence of the rules is very important, especially when using general definitions. Then the file can be immediately activated by reloading the security files. About item #1, I will forward your suggestion to Development Support. Its functions are then used by the ABAP system on the same host. 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. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. A LINE with a HOST entry having multiple host names (e.g. The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. The tax system is running on the server taxserver. The RFC Gateway can be seen as a communication middleware. All other programs starting with cpict4 are allowed to be started (on every host and by every user). 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 can define the file path using profile parameters gw/sec_infoand gw/reg_info. Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. Please note: The wildcard * is per se supported at the end of a string only. Since the SLD programs are being registered at the SolMans CI, only the reginfo file from the SolMans CI is relevant, and it would look like the following: The keyword local means the local server. If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* 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. All other programs from host 10.18.210.140 are not allowed to be registered. As such, it is an attractive target for hacker attacks and should receive corresponding protections. Part 8: OS command execution using sapxpg. Please follow me to get a notification once i publish the next part of the series. 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.
