If the Gateway protections fall short, hacking it becomes childs play. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. 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. 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. Its functions are then used by the ABAP system on the same host. Only the secinfo from the CI is applicable, as it is the RFC Gateway from the CI that will be used to start the program (check the Gateway Options at the screenshot above). Sie knnen die Queue-Auswahl reduzieren. Its location is defined by parameter gw/sec_info. All subsequent rules are not checked at all. 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. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. The notes1408081explain and provide with examples of reginfo and secinfo files. This way, each instance will use the locally available 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')). Giving more details is not possible, unfortunately, due to security reasons. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. Each instance can have its own security files with its own rules. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS). Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. However, you still receive the "Access to registered program denied" / "return code 748" error. The network service that, in turn, manages the RFC communication is provided by the RFC Gateway. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. The syntax used in the reginfo, secinfo and prxyinfo changed over time. 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"}. 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. The other parts are not finished, yet. A custom allow rule has to be maintained on the proxying RFC Gateway only. For this scenario a custom rule in the reginfo ACL would be necessary, e.g., P TP= HOST= ACCESS=internal,local CANCEL=internal,local,. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. 2.20) is taken into account only if every comma-separated entry can be resolved into an IP address. Part 2: reginfo ACL in detail 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 reginfo ACL contains rules related to Registered external RFC Servers. We should pretend as if we would maintain the ACLs of a stand-alone RFC Gateway. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. This is defined in, how many Registered Server Programs with the same name can be registered. The RFC Gateway does not perform any additional security checks. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. Every attribute should be maintained as specific as possible. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. This is a list of host names that must comply with the rules above. There are other SAP notes that help to understand the syntax (refer to the Related notes section below). 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. It is common to define this rule also in a custom reginfo file as the last rule. It is important to mention that the Simulation Mode applies to the registration action only. Alerting is not available for unauthorized users. Even if the system is installed with an ASCS instance (ABAP Central Services comprising the message server and the standalone enqueue server), a Gateway can still be configured on the ASCS instance. 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. Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. The secinfo file has rules related to the start of programs by the local SAP instance. 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. (any helpful wiki is very welcome, many thanks toIsaias Freitas). Please follow me to get a notification once i publish the next part of the series. 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. If no access list is specified, the program can be used from any client. Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. Save ACL files and restart the system to activate the parameters. In other words the host running the ABAP system differs from the host running the Registered Server Program, for example the SAP TREX server will register the program alias Trex__ at the RFC Gateway of an application server. The Gateway uses the rules in the same order in which they are displayed in the file. In these cases the program alias is generated with a random string. This list is gathered from the Message Server every 5 minutes by the report RSMONGWY_SEND_NILIST. The Gateway is the technical component of the SAP server that manages the communication for all RFC-based functions. Visit SAP Support Portal's SAP Notes and KBA Search. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. 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). Then the file can be immediately activated by reloading the security files. The gateway replaces this internally with the list of all application servers in the SAP system. The local gateway where the program is registered can always cancel the program. Ergebnis Sie haben eine Queue definiert. Only clients from domain *.sap.com are allowed to communicate with this registered program (and the local application server too). 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 . E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. D prevents this program from being started. Maybe some security concerns regarding the one or the other scenario raised already in you head. 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. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. 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. RFCs between two SAP NetWeaver AS ABAP systems are typically controlled on network level only. This parameter will enable special settings that should be controlled in the configuration of reginfo file. 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. In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_SEC_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. 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. Every line corresponds one rule. There may also be an ACL in place which controls access on application level. The location of this ACL can be defined by parameter gw/acl_info. Please note: SNC User ACL is not a feature of the RFC Gateway itself. 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. The first letter of the rule can begin with either P (permit) or D (deny). All of our custom rules should bee allow-rules. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. 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. The secinfosecurity file is used to prevent unauthorized launching of external programs. To control access from the client side too, you can define an access list for each entry. Dieses Verfahren ist zwar sehr restriktiv, was fr die Sicherheit spricht, hat jedoch den sehr groen Nachteil, dass in der Erstellungsphase immer Verbindungen blockiert werden, die eigentlich erwnscht sind. In production systems, generic rules should not be permitted. The secinfo file is holding rules controlling which programs (based on their executable name or fullpath, if not in $PATH) can be started by which user calling from which host(s) (based on its hostname/ip-address) on which RFC Gateway server(s) (based on their hostname/ip-address). To set up the recommended secure SAP Gateway configuration, proceed as follows:. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. Program cpict4 is not permitted to be started. However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). Someone played in between on reginfo file. As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: The first letter of the rule can be either P (for Permit) or D (for Deny). Furthermore the means of some syntax and security checks have been changed or even fixed over time. 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). It registers itself with the program alias IGS. at the RFC Gateway of the same application server. if the server is available again, this as error declared message is obsolete. As such, it is an attractive target for hacker attacks and should receive corresponding protections. If the called program is not an RFC enabled program (compiled with the SAP RFC library) the call will time out, but the program is still left running on the OS level! P means that the program is permitted to be registered (the same as a line with the old syntax). 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. After the external program was registered, the ACCESS and CANCEL options will be followed as defined in the rule, if a rule existed. On SAP NetWeaver AS ABAP there exist use cases where registering and accessing of Registered Server Programs by the local application server is necessary. NUMA steht fr Non-Uniform Memory Access und beschreibt eine Computer-Speicher-Architektur fr Multiprozessorsysteme, bei der jeder Prozessor ber einen eigenen, lokalen physischen Speicher verfgt, aber anderen Prozessoren ber einen gemeinsamen Adressraum direkten Zugriff darauf gewhrt (Distributed Shared Memory). three months) is necessary to ensure the most precise data possible for the connections used. 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. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. Use host names instead of the IP address. Part 5: ACLs and the RFC Gateway security. We solved it by defining the RFC on MS. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. 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. All subsequent rules are not even checked. This publication got considerable public attention as 10KBLAZE. 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. Despite this, system interfaces are often left out when securing IT systems. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. 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. With this blogpost series i try to give a comprehensive explanation of the RFC Gateway Security: Part 1: General questions about the RFC Gateway and RFC Gateway security. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. Host Name (HOST=, ACCESS= and/or CANCEL=): The wildcard character * stands for any host name, *.sap.com for a domain, sapprod for host sapprod. 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. 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. Part 7: Secure communication Programs within the system are allowed to register. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. The default configuration of an ASCS has no Gateway. Please note: SNC System ACL is not a feature of the RFC Gateway itself. It seems to me that the parameter is gw/acl_file instead of ms/acl_file. Once you have completed the change, you can reload the files without having to restart the gateway. 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. CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. The RFC destination would look like: The secinfo files from the application instances are not relevant. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo 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. HOST = servername, 10. Part 4: prxyinfo ACL in detail 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. Part 5: Security considerations related to these ACLs. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan 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. There are two different versions of the syntax for both files: Syntax version 1 does not enable programs to be explicitly forbidden from being started or registered. 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. Part 8: OS command execution using sapxpg. 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. Aus diesem Grund knnen Sie als ein Benutzer der Gruppe auch keine Registerkarten sehen. 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. For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. Part 5: ACLs and the RFC Gateway security After reloading the file, it is necessary to de-register all registrations of the affected program, and re-register it again. 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. Part 5: ACLs and the RFC Gateway security. 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 blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. Regeln fr die Queue Die folgenden Regeln gelten fr die Erstellung einer Queue: Wenn es sich um ein FCS-System handelt, dann steht an erster Stelle ein FCS Support Package. Part 2: reginfo ACL in detail. RFCs between RFC clients using JCo/NCo or Registered Server Programs and the AS ABAP are typically controlled on network level only. You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. The subsequent blogs of will describe each individually. (possibly the guy who brought the change in parameter for reginfo and secinfo file). Add a Comment The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system.

Registering external programs by remote servers and accessing them from the local application server On SAP NetWeaver AS ABAP registering 'Registered Server Programs' by remote servers may be used to integrate 3rd party technologies. Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. If the TP name itself contains spaces, you have to use commas instead. The RFC Gateway can be seen as a communication middleware. 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. Its location is defined by parameter 'gw/reg_info'. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. 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. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. 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. The wildcard * should not be used at all. 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. Copyright |
Configuring Connections between SAP Gateway and External Programs Securely, SAP Gateway Security Files secinfo and reginfo, Setting Up Security Settings for External Programs. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. File reginfocontrols the registration of external programs in the gateway. The PI system has one Central Instance (CI) running at the server sappici, and one application instance (running at the server sappiapp1).
