If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* If USER-HOST is not specifed, the value * is accepted. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. The first line of the reginfo/secinfo files must be # VERSION = 2. 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. A LINE with a HOST entry having multiple host names (e.g. To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. Part 8: OS command execution using sapxpg. Now 1 RFC has started failing for program not registered. 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. About item #1, I will forward your suggestion to Development Support. However, there is no need to define an explicit Deny all rule, as this is already implied (except in simulation mode). Check the secinfo and reginfo files. The other parts are not finished, yet. 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. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Each instance can have its own security files with its own rules. 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. A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. Trademark. While it is common and recommended by many resources to define this rule in a custom reginfo ACL as the last rule, from a security perspective it is not an optimal approach. Part 4: prxyinfo ACL in detail. Part 5: ACLs and the RFC Gateway security. Examples of valid addresses are: Number (NO=): Number between 0 and 65535. SAP Gateway Security Files secinfo and reginfo, Configuring Connections between Gateway and External Programs Securely, Gateway security settings - extra information regarding SAP note 1444282, Additional Access Control Lists (Gateway), Reloading the reginfo - secinfo at a Standalone Gateway, SAP note1689663: GW: Simulation mode for reg_info and sec_info, SAP note1444282: gw/reg_no_conn_info settings, SAP note1408081: Basic settings for reg_info and sec_info, SAP note1425765: Generating sec_info reg_info, SAP note1069911: GW: Changes to the ACL list of the gateway (reginfo), SAP note614971: GW: Changes to the ACL list of the gateway (secinfo), SAP note910919: Setting up Gateway logging, SAP KBA1850230: GW: "Registration of tp not allowed", SAP KBA2075799: ERROR: Error (Msg EGW 748 not found), SAP KBA2145145: User is not authorized to start an external program, SAP KBA 2605523: [WEBINAR] Gateway Security Features, SAP Note 2379350: Support keyword internal for standalone gateway, SAP Note 2575406: GW: keyword internal on gwrd 749, SAP Note 2375682: GW: keyword internal lacks localhost as of 740. ooohhh my god, (It could not have been more complicated -obviously the sequence of lines is important): "# This must always be the last rule on the file see SAP note 1408081" + next line content, is not included as comment within the default-delivered reginfo file or secinfo file (after installation) -, this would save a lot ofwasted life time, gw/acl_mode: ( looks like to enable/disable the complete gw-security config, but ). About the second comment and the error messages, those are messages related to DNS lookup.I believe that these are raised as errors because they have occurred during the parsing of the reginfo 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. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. 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. So lets shine a light on security. E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* You have already reloaded the reginfo file. Part 6: RFC Gateway Logging. Limiting access to this port would be one mitigation. 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. Beachten Sie, da der SAP Patch Manager die Konfiguration Ihres SAP-Systems bercksichtigt und nur solche Support Packages in die Queue aufnimmt, die in Ihr System eingespielt werden drfen. The name of the registered program will be TAXSYS. Someone played in between on reginfo file. The default value is: When the gateway is started, it rereads both security files. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. It is common to define this rule also in a custom reginfo file as the last rule. 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. Checking the Security Configuration of SAP Gateway. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo Hello Venkateshwar, thank you for your comment. 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. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS). For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. Another example would be IGS. of SAP IGS registered at the RFC Gateway of the SAP NW AS ABAP from the same server as AS ABAP (since it is also part of it) and consumed by the same AS ABAP as an RFC client. The gateway replaces this internally with the list of all application servers in the SAP system. File reginfo controls the registration of external programs in the gateway. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. 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. With this rule applied you should properly secure access to the OS (e.g., verify if all existing OS users are indeed necessary, SSH with public key instead of user+pw). 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. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . RFC had issue in getting registered on DI. 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. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. Part 7: Secure communication 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. 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). 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. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). 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. 2. The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. Thank you! After reloading the file, it is necessary to de-register all registrations of the affected program, and re-register it again. There are various tools with different functions provided to administrators for working with security files. The location of this ACL can be defined by parameter gw/acl_info. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. This could be defined in. Someone played in between on reginfo file. *. The following syntax is valid for the secinfo file. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. Such third party system is to be started on demand by the SAP system.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.You have an RFC destination named TAX_SYSTEM. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. The order of the remaining entries is of no importance. IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. Refer to the SAP Notes 2379350 and2575406 for the details. Only the first matching rule is used (similarly to how a network firewall behaves). Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. 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. RFC had issue in getting registered on DI. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. Copyright |
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 Sie knnen die Queue-Auswahl reduzieren. 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. About this page This is a preview of a SAP Knowledge Base Article. 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. 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. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. Program cpict4 is not permitted to be started. To edit the security files,you have to use an editor at operating system level. In SAP NetWeaver Application Server Java: The SCS instance has a built-in RFC Gateway. (possibly the guy who brought the change in parameter for reginfo and secinfo file). Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. 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. 2.20) is taken into account only if every comma-separated entry can be resolved into an IP address. P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. All programs started by hosts within the SAP system can be started on all hosts in the system. Common examples are the program tp for transport management via STMS started on the RFC Gateway host of AS ABAP or the program gnetx.exe for the graphical screen painter started on the SAP GUI client host. Another mitigation would be to switch the internal server communication to TLS using a so-called systemPKI by setting the profile parameter system/secure_communication = ON. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. 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. This diagram shows all use-cases except `Proxy to other RFC Gateways. Datenbankschicht: In der Datenbank, welche auf einem Datenbankserver liegt, werden alle Daten eines Unternehmens gesichert. If this addition is missing, any number of servers with the same ID are allowed to log on. However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. Please pay special attention to this phase! 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 can I quickly migrate SAP custom code to S/4HANA? 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. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. The SAP note1689663has the information about this topic. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. 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). 3. Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted. Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. 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. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. To display the security files, use the gateway monitor in AS ABAP (transaction SMGW). Benign programs to be started by the local RFC Gateway of a SAP NetWeaver AS ABAP are typically part of the SAP Kernel and located in the $(DIR_EXE) of the application server. Most of the cases this is the troublemaker (!) As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. Part 7: Secure communication You can tighten this authorization check by setting the optional parameter USER-HOST. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. This way, each instance will use the locally available tax system. In a pure Java system, one Gateway is sufficient for the whole system because the instances do not use RFC to communicate. File reginfocontrols the registration of external programs in the gateway. If the TP name itself contains spaces, you have to use commas instead. The simulation mode is a feature which could help to initially create the ACLs. The local gateway where the program is registered can always cancel the program. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. 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. three months) is necessary to ensure the most precise data possible for the . All subsequent rules are not checked at all. Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. Part 5: ACLs and the RFC Gateway security. Giving more details is not possible, unfortunately, due to security reasons. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. The secinfo file has rules related to the start of programs by the local SAP instance. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. 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. 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 5: Security considerations related to these ACLs. Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. Its functions are then used by the ABAP system on the same host. This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. At time of writing this can not be influenced by any profile parameter. In SAP NetWeaver Application Server ABAP: Every Application Server has a built-in RFC Gateway. The reginfo ACL contains rules related to Registered external RFC Servers. The wildcard * should be strongly avoided. Part 2: reginfo ACL in detail Its location is defined by parameter 'gw/reg_info'. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. You can also control access to the registered programs and cancel registered programs. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. 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). Save ACL files and restart the system to activate the parameters. Ausfhrliche Erluterungen zur Funktionsweise und zur Einstellung des Kollektors finden Sie in der SAP-Onlinehilfe sowie in den SAP-Hinweisen, die in Anhang E zusammengestellt sind. 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). Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. 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 case of TP Name this may not be applicable in some scenarios. 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. 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. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. Part 7: Secure communication 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). 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. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. It seems to me that the parameter is gw/acl_file instead of ms/acl_file. As i suspect it should have been registered from Reginfo file rather than OS. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Hufig ist man verpflichtet eine Migration durchzufhren. ABAP SAP Basis Release as from 7.40 . Make sure that they are set as per the Notes: Note 1425765 - Generating sec_info reg_info Note 1947412 - MDM Memory increase and RFC connection error The related program alias also known as TP Name is used to register a program at the RFC Gateway. In this case the Gateway Options must point to exactly this RFC Gateway host. P TP=* USER=* USER-HOST=internal HOST=internal. A general secinfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): Only the (SAP level) user IDs BOB and JOHN can start this program, and they will be logged on to one of the instances from this SAP system. This publication got considerable public attention as 10KBLAZE. Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. The RFC Gateway is capable to start programs on the OS level. 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. 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 . 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. The reginfo file has the following syntax. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. Part 4: prxyinfo ACL in detail. This parameter will enable special settings that should be controlled in the configuration of reginfo file. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. 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). 2. 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). It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. The wildcard * should not be used at all. As i suspect it should have been registered from Reginfo file rather than OS. 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 the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. Part 4: prxyinfo ACL in detail Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. To set up the recommended secure SAP Gateway configuration, proceed as follows:. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Program hugo is allowed to be started on every local host and by every user. 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. 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. In other words, the SAP instance would run an operating system level command. Privacy |
