Wir untersttzen Sie gerne bei Ihrer Entscheidungen. In this case the Gateway Options must point to exactly this RFC Gateway host. This means that if the file is changed and the new entries immediately activated, the servers already logged on will still have the old attributes. In other words, the SAP instance would run an operating system level command. 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. Access attempts coming from a different domain will be rejected. 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. (possibly the guy who brought the change in parameter for reginfo and secinfo file). Sobald dieses Recht vergeben wurde, taucht die Registerkarte auch auf der CMC-Startseite wieder auf. If the Gateway protections fall short, hacking it becomes childs play. This means the call of a program is always waiting for an answer before it times out. P SOURCE=* DEST=*. All other programs starting with cpict4 are allowed to be started (on every host and by every user). 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). 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. This is for clarity purposes. Legal Disclosure | 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. The default configuration of an ASCS has no Gateway. Would you like more information on our SAST SUITE or would you like to find out more about ALL ROUND protection of your SAP systems? However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. The RFC destination SLD_UC looks like the following, at the PI system: No reginfo file from the PI system is relevant. From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. In case of TP Name this may not be applicable in some scenarios. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. 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. 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. 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. 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. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. As such, it is an attractive target for hacker attacks and should receive corresponding protections. File reginfocontrols the registration of external programs in the gateway. Part 5: ACLs and the RFC Gateway security. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. This publication got considerable public attention as 10KBLAZE. Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. An example could be the integration of a TAX software. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. Only clients from the local application server are allowed to communicate with this registered program. The local gateway where the program is registered always has access. TP is a mandatory field in the secinfo and reginfo files. 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. At time of writing this can not be influenced by any profile parameter. 3. 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. The simulation mode is a feature which could help to initially create the ACLs. The RFC Gateway is capable to start programs on the OS level. Please assist me how this change fixed it ? Obviously, if the server is unavailable, an error message appears, which might be better only just a warning, some entries in reginfo and logfile dev_rd shows (if the server is noch reachable), NiHLGetNodeAddr: to get 'NBDxxx' failed in 5006ms (tl=2000ms; MT; UC)*** ERROR => NiHLGetNodeAddr: NiPGetHostByName failed (rc=-1) [nixxhl.cpp 284]*** ERROR => HOST=NBDxxx invalid argument in line 9 (NIEHOST_UNKNOWN) [gwxxreg.c 2897]. Limiting access to this port would be one mitigation. The Solution Manager (SolMan) system has only one instance, running at the host sapsmci. In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. Example Example 1: Accessing reginfo file from SMGW a pop is displayed thatreginfo at file system and SAP level is different. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. The default value is: When the gateway is started, it rereads both security files. if the server is available again, this as error declared message is obsolete. Alerting is not available for unauthorized users. In case you dont want to use the keyword, each instance would need a specific rule. Check out our SAST SOLUTIONS website or send us an e-mail us at sast@akquinet.de. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Refer to the SAP Notes 2379350 and2575406 for the details. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. 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 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. Sie knnen die Queue-Auswahl reduzieren. The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. 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). 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. Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. Part 7: Secure communication As we learned in part 2 SAP introduced the following internal rule in the in the reginfo ACL: P TP=* HOST=internal,local ACCESS=internal,local CANCEL=internal,local. 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. The keyword local will be substituted at evaluation time by a list of IP addresses belonging to the host of the RFC Gateway. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. In a pure Java system, one Gateway is sufficient for the whole system because the instances do not use RFC to communicate. Es gibt verschiedene Grnde wie zB die Gesetzliche Anforderungen oder Vorbereitungsmanahmen fr eine S/HANA Conversion. 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. The order of the remaining entries is of no importance. The network service that, in turn, manages the RFC communication is provided by the RFC Gateway. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. Ergebnis Sie haben eine Queue definiert. Specifically, it helps create secure ACL files. Access to the ACL files must be restricted. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. 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. 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. It is important to mention that the Simulation Mode applies to the registration action only. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. Terms of use | 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. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. The default rule in prxyinfo ACL (as mentioned in part 4) is enabled if no custom ACL is defined. The very first line of the reginfo/secinfo file must be "#VERSION=2"; Each line must be a complete rule (you cannot break the rule into two or more lines); The RFC Gateway will apply the rules in the same order as they appear in the file, and only the first matching rule will be used (similar to the behavior of a network firewall). 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. 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. Read more. Datenbankschicht: In der Datenbank, welche auf einem Datenbankserver liegt, werden alle Daten eines Unternehmens gesichert. In production systems, generic rules should not be permitted. Each instance can have its own security files with its own rules. Add a Comment The gateway replaces this internally with the list of all application servers in the SAP system. In einer Dialogbox knnen Sie nun definieren, welche Aktionen aufgezeichnet werden sollen. secinfo: P TP=* USER=* USER-HOST=* HOST=*. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . There may also be an ACL in place which controls access on application level. Someone played in between on reginfo file. The Gateway is a central communication component of an SAP system. 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. Part 4: prxyinfo ACL in detail. three months) is necessary to ensure the most precise data possible for the connections used. P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. The solution is to stop the SLD program, and start it again (in other words, de-register the program, and re-register it). 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. Part 4: prxyinfo ACL in detail. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. 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). 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"}. 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. Part 6: RFC Gateway Logging The first line of the reginfo/secinfo files must be # VERSION = 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 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 Gateway is the technical component of the SAP server that manages the communication for all RFC-based functions. If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* 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. Part 4: prxyinfo ACL in detail. The secinfosecurity file is used to prevent unauthorized launching of external programs. Every attribute should be maintained as specific as possible. 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. 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). It also enables communication between work or server processes of SAP NetWeaver AS and external programs. 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. Most of the cases this is the troublemaker (!) Here, the Gateway is used for RFC/JCo connections to other systems. This publication got considerable public attention as 10KBLAZE. File reginfocontrols the registration of external programs in the gateway. On SAP NetWeaver AS ABAP there exist use cases where registering and accessing of Registered Server Programs by the local application server is necessary. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. 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. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . If the TP name itself contains spaces, you have to use commas instead. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. So lets shine a light on security. To edit the security files,you have to use an editor at operating system level. The secinfosecurity file is used to prevent unauthorized launching of external programs. The syntax used in the reginfo, secinfo and prxyinfo changed over time. Its location is defined by parameter gw/prxy_info. If no cancel list is specified, any client can cancel the program. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. 1. other servers had communication problem with that DI. Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. If this addition is missing, any number of servers with the same ID are allowed to log on. Part 1: General questions about the RFC Gateway and RFC Gateway security. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. 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. 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. Its location is defined by parameter gw/sec_info. This diagram shows all use-cases except `Proxy to other RFC Gateways. In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. 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. 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. After reloading the file, it is necessary to de-register all registrations of the affected program, and re-register it again. 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. As we learned in part 4 SAP introduced the following internal rule in the in the prxyinfo ACL: Configuring Connections between SAP Gateway and External Programs Securely, SAP Gateway Security Files secinfo and reginfo, Setting Up Security Settings for External Programs. this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. This order is not mandatory. Hufig ist man verpflichtet eine Migration durchzufhren. Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20].
