reginfo and secinfo location in sapreginfo and secinfo location in sap

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. 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. If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. TP is a mandatory field in the secinfo and reginfo files. Ergebnis Sie haben eine Queue definiert. 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 Most of the cases this is the troublemaker (!) This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. Part 5: Security considerations related to these ACLs. Fr die gewnschten Registerkarten "Gewhren" auswhlen. In these cases the program alias is generated with a random string. Part 6: RFC Gateway Logging. 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). Someone played in between on reginfo file. This means that the sequence of the rules is very important, especially when using general definitions. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. The network service that, in turn, manages the RFC communication is provided by the RFC Gateway. Only the first matching rule is used (similarly to how a network firewall behaves). This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). The other parts are not finished, yet. 1. other servers had communication problem with that DI. An example could be the integration of a TAX software. 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. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. so for me it should only be a warning/info-message. 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. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. 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 this case the Gateway Options must point to exactly this RFC Gateway host. Someone played in between on reginfo file. The first letter of the rule can begin with either P (permit) or D (deny). 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). On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. Part 5: ACLs and the RFC Gateway security. After the external program was registered, the ACCESS and CANCEL options will be followed as defined in the rule, if a rule existed. There are various tools with different functions provided to administrators for working with security files. The RFC library provides functions for closing registered programs. TP is restricted to 64 non-Unicode characters for both secinfo and reginfo files. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. Now 1 RFC has started failing for program not registered. You can define the file path using profile parameters gw/sec_info and gw/reg_info. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. If the option is missing, this is equivalent to HOST=*. 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. Part 5: ACLs and the RFC Gateway security 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. Please note: SNC System ACL is not a feature of the RFC Gateway itself. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. 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. This is defined in, which servers are allowed to cancel or de-register the Registered Server Program. 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. D prevents this program from being started. The Stand-alone RFC Gateway: As a dedicated RFC Gateway serving for various RFC clients or as an additional component which may be used to extend a SAP NW AS ABAP or AS Java system. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). Access to this ports is typically restricted on network level. If this addition is missing, any number of servers with the same ID are allowed to log on. RFCs between two SAP NetWeaver AS ABAP systems are typically controlled on network level only. Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. File reginfocontrols the registration of external programs in the gateway. D prevents this program from being registered on the gateway. This parameter will enable special settings that should be controlled in the configuration of reginfo file. Configuring Connections between SAP Gateway and External Programs Securely, SAP Gateway Security Files secinfo and reginfo, Setting Up Security Settings for External Programs. Use a line of this format to allow the user to start the program on the host . They are: The diagram below shows the workflow of how the RFC Gateway works with the security rules and the involved parameters, like the Simulation Mode. 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. 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. It seems to me that the parameter is gw/acl_file instead of ms/acl_file. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. The tax system is running on the server taxserver. 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. (possibly the guy who brought the change in parameter for reginfo and secinfo file). Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. Additional ACLs are discussed at this WIKI page. Falls Sie danach noch immer keine Anwendungen / Registerkarten sehen, liegt es daran, dass der Gruppe / dem Benutzer das allgemeine Anzeigenrecht auf der obersten Ebene der jeweiligen Registerkarte fehlt. 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. 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. After reloading the file, it is necessary to de-register all registrations of the affected program, and re-register it again. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. With this rule applied for example any user with permissions to create or edit TCP/IP connections in transaction SM59 would be able to call any executable or script at OS level on the RFC Gateway server in the context of the user running the RFC gateway process. P TP=* USER=* USER-HOST=internal HOST=internal. This is because the rules used are from the Gateway process of the local instance. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. Part 2: reginfo ACL in detail. Every line corresponds one rule. Checking the Security Configuration of SAP Gateway. Part 7: Secure communication What is important here is that the check is made on the basis of hosts and not at user level. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. Legal Disclosure | 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. *. 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. The reginfo file has the following syntax. Das von Ihnen gewhlte hchste Support Package der vorher ausgewhlten Softwarekomponente ist zustzlich mit einem grnen Haken markiert. Host Name (HOST=, ACCESS= and/or CANCEL=): The wildcard character * stands for any host name, *.sap.com for a domain, sapprod for host sapprod. We should pretend as if we would maintain the ACLs of a stand-alone RFC Gateway. How can I quickly migrate SAP custom code to S/4HANA? If the Gateway protections fall short, hacking it becomes childs play. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. The secinfosecurity file is used to prevent unauthorized launching of external programs. 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. All subsequent rules are not checked at all. Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. 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"}. 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. Read more. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. This opensb the Gateway ACL Editor, where you can display the relevant files.. To enable system-internal communication, the files must contain the . 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 erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo P USER=* USER-HOST=internal,local HOST=internal,local TP=*. 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. Part 4: prxyinfo ACL in detail. There may also be an ACL in place which controls access on application level. 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. If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* The first line of the reginfo/secinfo files must be # VERSION = 2. Part 5: Security considerations related to these ACLs. Please pay special attention to this phase! Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. Please assist me how this change fixed it ? Program cpict4 is allowed to be registered by any host. Somit knnen keine externe Programme genutzt werden. 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. The RFC Gateway is capable to start programs on the OS level. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. The solution is to stop the SLD program, and start it again (in other words, de-register the program, and re-register it). 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. It registers itself with the program alias IGS. at the RFC Gateway of the same application server. To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. Access attempts coming from a different domain will be rejected. 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). Part 2: reginfo ACL in detail Part 3: secinfo ACL in detail. 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. Examples of valid addresses are: Number (NO=): Number between 0 and 65535. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS). 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. The secinfo file has rules related to the start of programs by the local SAP instance. In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. 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. It is common to define this rule also in a custom reginfo file as the last rule. Check out our SAST SOLUTIONS website or send us an e-mail us at sast@akquinet.de. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). if the server is available again, this as error declared message is obsolete. While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. The location of this ACL can be defined by parameter gw/acl_info. The Gateway is the technical component of the SAP server that manages the communication for all RFC-based functions. Part 8: OS command execution using sapxpg. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. . 2. 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 Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. Part 8: OS command execution using sapxpg. 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. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. The internal value for the host options (HOST and USER HOST) applies to all hosts in the 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. Its functions are then used by the ABAP system on the same host. This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. 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. Maybe some security concerns regarding the one or the other scenario raised already in you head. The RFC Gateway can be used to proxy requests to other RFC Gateways. Part 2: reginfo ACL in detail. 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. As i suspect it should have been registered from Reginfo file rather than OS. RFC had issue in getting registered on DI. (any helpful wiki is very welcome, many thanks toIsaias Freitas). It also enables communication between work or server processes of SAP NetWeaver AS and external programs. Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. 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. ABAP SAP Basis Release as from 7.40 . 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. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. 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 the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. Its location is defined by parameter gw/sec_info. Of course the local application server is allowed access. 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). 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. The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. In case of TP Name this may not be applicable in some scenarios. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. where ist the hint or wiki to configure a well runing gw-security ? A combination of these mitigations should be considered in general. The default configuration of an ASCS has no Gateway. This means the call of a program is always waiting for an answer before it times out. Part 7: Secure communication You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. Program cpict4 is not permitted to be started. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. We solved it by defining the RFC on MS. 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. Part 7: Secure communication The Gateway uses the rules in the same order in which they are displayed in the file. Use host names instead of the IP address. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. Please make sure you have read part 1 4 of this series. 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. This makes sure application servers must have a trust relation in order to take part of the internal server communication. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. If no cancel list is specified, any client can cancel the program. In production systems, generic rules should not be permitted. Check the secinfo and reginfo files. The secinfo security file is used to prevent unauthorized launching of external programs. The secinfo file has rules related to the start of programs by the local SAP instance. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. It is important to mention that the Simulation Mode applies to the registration action only. In SAP NetWeaver Application Server ABAP: Every Application Server has a built-in RFC Gateway. For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). Falls es in der Queue fehlt, kann diese nicht definiert werden. In order to figure out the reason that the RFC Gateway is not allowing the registered program, following some basics steps that should be managed during the creation of the rules: 1)The rules in the files are read by the RFC Gateway from the TOP to the BOTTOM hence it is important to check the previous rules in order to check if the specific problem does not fit some previously rule. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. We first registered it on the server it is defined (which was getting de-registered after a while so we registered it again through background command nohup *** & ), This solved the RFC communication on that Dialogue instance yet other Dialogue instances were not able to communicate on the RFC. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. About item #1, I will forward your suggestion to Development Support. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. All programs started by hosts within the SAP system can be started on all hosts in the system. RFC had issue in getting registered on DI. Please make sure you have read at least part 1 of this series to be familiar with the basics of the RFC Gateway and the terms i use to describe things. Save ACL files and restart the system to activate the parameters. For this scenario a custom rule in the reginfo ACL would be necessary, e.g., P TP= HOST= ACCESS=internal,local CANCEL=internal,local,. For example: The SAP KBAs1850230and2075799might be helpful. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. So lets shine a light on security. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. 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). In SAP NetWeaver Application Server Java: The SCS instance has a built-in RFC Gateway. Privacy | 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).
