Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. 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. The format of the first line is #VERSION=2, all further lines are structured as follows: Here the line starting with P or D, followed by a space or a TAB, has the following meaning: P means that the program is permitted to be started (the same as a line with the old syntax). Wir untersttzen Sie gerne bei Ihrer Entscheidungen. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* Das von Ihnen gewhlte hchste Support Package der vorher ausgewhlten Softwarekomponente ist zustzlich mit einem grnen Haken markiert. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. 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. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. 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 This parameter will enable special settings that should be controlled in the configuration of reginfo file. 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 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! 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. 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. The Gateway is the technical component of the SAP server that manages the communication for all RFC-based functions. You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. 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 first letter of the rule can begin with either P (permit) or D (deny). Alerting is not available for unauthorized users, Right click and copy the link to share this comment. 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. In an ideal world each program alias of the relevant Registered Server Programs would be listed in a separate rule, even for registering program aliases from one of the hosts of internal. 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. 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. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo Copyright | Part 4: prxyinfo ACL in detail. We solved it by defining the RFC on MS. This is for clarity purposes. 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). 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. There is an SAP PI system that needs to communicate with the SLD. This way, each instance will use the locally available tax system. Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. This publication got considerable public attention as 10KBLAZE. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. Part 3: secinfo ACL in detail. The following syntax is valid for the secinfo file. 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. In this case the Gateway Options must point to exactly this RFC Gateway host. A LINE with a HOST entry having multiple host names (e.g. 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. 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. Please assist me how this change fixed it ? The secinfo file has rules related to the start of programs by the local SAP instance. . 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. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. Hinweis: Whlen Sie ber den Button und nicht das Dropdown-Men Gewhren aus! To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. File reginfo controls the registration of external programs in the gateway. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. 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. At time of writing this can not be influenced by any profile parameter. HOST = servername, 10. 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. 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. Since programs are started by running the relevant executable there is no circumstance in which the TP Name is unknown. Alerting is not available for unauthorized users, Right click and copy the link to share this comment, Part 1: General questions about the RFC Gateway and RFC Gateway security, Part 8: OS command execution using sapxpg, Secure Server Communication in SAP Netweaver AS ABAP. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. Access to the ACL files must be restricted. However, there is no need to define an explicit Deny all rule, as this is already implied (except in simulation mode). With secinfo file this corresponds to the name of the program on the operating system level. Program hugo is allowed to be started on every local host and by every user. Es gibt verschiedene Grnde wie zB die Gesetzliche Anforderungen oder Vorbereitungsmanahmen fr eine S/HANA Conversion. Part 4: prxyinfo ACL in detail. Host Name (HOST=, ACCESS= and/or CANCEL=): The wildcard character * stands for any host name, *.sap.com for a domain, sapprod for host sapprod. Besttigen Sie den auftauchenden Hinweis und vergeben Sie fr die gewnschten Gruppen zumindest das folgende Recht: Allgemein --> Allgemein --> Objekte Anzeigen. 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. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo If the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. Refer to the SAP Notes 2379350 and2575406 for the details. The tax system is running on the server taxserver. In addition, the existing rules on the reginfo/secinfo file will be applied, even on Simulation Mode. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. The default rules of reginfo and secinfo ACL (as mentioned in part 2 and part 3) are enabled if either profile parameter gw/acl_mode = 1 is set or if gw/reg_no_conn_info includes the value 16 in its bit mask, and if no custom ACLs are defined. 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. Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. 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')). 2. 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. E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted. All programs started by hosts within the SAP system can be started on all hosts in the system. To edit the security files,you have to use an editor at operating system level. 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. Its location is defined by parameter gw/reg_info. 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. In a pure Java system, one Gateway is sufficient for the whole system because the instances do not use RFC to communicate. Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. P means that the program is permitted to be registered (the same as a line with the old syntax). All other programs starting with cpict4 are allowed to be started (on every host and by every user). To set up the recommended secure SAP Gateway configuration, proceed as follows:. Part 3: secinfo ACL in detail For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. Please note: SNC User ACL is not a feature of the RFC Gateway itself. 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. 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. 1. other servers had communication problem with that DI. Fr die gewnschten Registerkarten "Gewhren" auswhlen. 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. 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. Somit knnen keine externe Programme genutzt werden. The secinfosecurity file is used to prevent unauthorized launching of external programs. You can also control access to the registered programs and cancel registered programs. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. When using SNC to secure RFC destinations on AS ABAP the so called SNC System ACL, also known as System Authentication, is introduced and must be maintained accordingly. All of our custom rules should bee allow-rules. For example: The SAP KBAs1850230and2075799might be helpful. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. Limiting access to this port would be one mitigation. 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. Privacy | If the option is missing, this is equivalent to HOST=*. Please assist ASAP. (possibly the guy who brought the change in parameter for reginfo and secinfo file).

CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. If no cancel list is specified, any client can cancel the program. 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. Read more. Most common use-case is the SAP-to-SAP communication, in other words communication via RFC connections between SAP NetWeaver AS systems, but also communication from RFC clients using the SAP Java Connector (JCo) or the SAP .NET Connector (NCo) to SAP NetWeaver systems. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. gw/acl_mode: this parameter controls the value of the default internal rules that the RFC Gateway will use, in case the reginfo/secinfo file is not maintained. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. 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. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. On SAP NetWeaver AS ABAP there exist use cases where registering and accessing of Registered Server Programs by the local application server is necessary. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. Maybe some security concerns regarding the one or the other scenario raised already in you head. The RFC destination would look like: The secinfo files from the application instances are not relevant. Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. This could be defined in. 1408081 - Basic settings for reg_info and sec_info 1702229 - Precalculation: Specify Program ID in sec_info and reg_info. Every line corresponds one rule. Hufig ist man verpflichtet eine Migration durchzufhren. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. 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 Please make sure you have read part 1 4 of this series. If you have a program registered twice, and you restart only one of the registrations, one of the registrations will continue to run with the old rule (the one that was not restarted after the changes), and another will be running with the current rule (the recently restarted registration). The 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). 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. Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. Sie knnen die Queue-Auswahl reduzieren. Here, the Gateway is used for RFC/JCo connections to other systems. Each instance can have its own security files with its own rules. Access to this ports is typically restricted on network level. Program cpict4 is not permitted to be started. Part 6: RFC Gateway Logging. (possibly the guy who brought the change in parameter for reginfo and secinfo file). The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). Check out our SAST SOLUTIONS website or send us an e-mail us at sast@akquinet.de. I think you have a typo. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. Program foo is only allowed to be used by hosts from domain *.sap.com. The network service that, in turn, manages the RFC communication is provided by the RFC Gateway. 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. There are various tools with different functions provided to administrators for working with security files. 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). 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). 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). 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). 1. other servers had communication problem with that DI. 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). Part 8: OS command execution using sapxpg. 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. Part 2: reginfo ACL in detail. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. 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. The RFC Gateway can be seen as a communication middleware. In other words, the SAP instance would run an operating system level command. 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. A Stand-alone Gateway could utilise this keyword only after it was attached to the Message Server of AS ABAP and the profile parameter gw/activate_keyword_internal was set. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. 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. P SOURCE=* DEST=*. The other parts are not finished, yet. As separators you can use commas or spaces. Only the first matching rule is used (similarly to how a network firewall behaves). Evaluate the Gateway log files and create ACL rules. If USER-HOST is not specifed, the value * is accepted. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. The order of the remaining entries is of no importance. Part 5: ACLs and the RFC Gateway security. Part 6: RFC Gateway Logging. D prevents this program from being started. 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). Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. The default configuration of an ASCS has no Gateway. What is important here is that the check is made on the basis of hosts and not at user level.
