reginfo and secinfo location in sap

Only clients from domain *.sap.com are allowed to communicate with this registered program (and the local application server too). Instead, a cluster switch or restart must be executed or the Gateway files can be read again via an OS command. The default configuration of an ASCS has no Gateway. Wechseln Sie dazu auf die gewnschte Registerkarte (im Beispiel ist das Universen), whlen Sie Verwalten --> Sicherheit auf oberster Ebene --> Alle Universen (je nach Registerkarte unterscheidet sich der letzte Punkt). Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. Someone played in between on reginfo file. Part 5: ACLs and the RFC Gateway security. Example Example 1: In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. The following steps usually need to be done manually to secure an SAP Gateway: Our SAST Interface Management module in the SAST SUITE provides support in hardening the SAP Gateway. 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 3: secinfo ACL in detail. This order is not mandatory. Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. 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. 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. Only the first matching rule is used (similarly to how a network firewall behaves). All other programs from host 10.18.210.140 are not allowed to be registered. To set up the recommended secure SAP Gateway configuration, proceed as follows:. 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. All of our custom rules should bee allow-rules. 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. In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. 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. 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. Limiting access to this port would be one mitigation. 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 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. 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. After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). 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. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. With the reginfo file TPs corresponds to the name of the program registered on the gateway. The first line of the reginfo/secinfo files must be # VERSION = 2. Please make sure you have read part 1 4 of this series. Stattdessen bekommen Sie eine Fehlermeldung, in der Ihnen der Name des fehlenden FCS Support Package mitgeteilt wird. The secinfo file has rules related to the start of programs by the local SAP instance. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. 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. secinfo: P TP=* USER=* USER-HOST=* HOST=*. Part 8: OS command execution using sapxpg. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. However, you still receive the "Access to registered program denied" / "return code 748" error. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. Giving more details is not possible, unfortunately, due to security reasons. As i suspect it should have been registered from Reginfo file rather than OS. 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 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. All other programs starting with cpict4 are allowed to be started (on every host and by every user). BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . 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 keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). 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. 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. 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). 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). Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. Click more to access the full version on SAP for Me (Login . 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. Always document the changes in the ACL files. If no access list is specified, the program can be used from any 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. Programs within the system are allowed to register. This way, each instance will use the locally available tax system. Now 1 RFC has started failing for program not 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. 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 3: secinfo ACL in detail Part 6: RFC Gateway Logging. In a pure Java system, one Gateway is sufficient for the whole system because the instances do not use RFC to communicate. Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted. 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. Read more. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. This opensb the Gateway ACL Editor, where you can display the relevant files.. To enable system-internal communication, the files must contain the . The syntax used in the reginfo, secinfo and prxyinfo changed over time. 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. 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. From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. It is important to mention that the Simulation Mode applies to the registration action only. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. 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. Hinweis: Whlen Sie ber den Button und nicht das Dropdown-Men Gewhren aus! Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). To assign the new settings to the registered programs too (if they have been changed at all), the servers must first be deregistered and then registered again. Sie knnen die Queue-Auswahl reduzieren. Es gibt folgende Grnde, die zum Abbruch dieses Schrittes fhren knnen: CANNOT_SKIP_ATTRIBUTE_RECORD: Die Attribute knnen in der OCS-Datei nicht gelesen werden. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. 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. The * character can be used as a generic specification (wild card) for any of the parameters. There are various tools with different functions provided to administrators for working with security files. 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. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. 3. 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. P means that the program is permitted to be registered (the same as a line with the old syntax). Specifically, it helps create secure ACL files. A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. In some cases any application server of the same system may also need to de-register a Registered Server Program, for example if the reginfo ACL was adjusted for the same Registered Server Program or if the remote server crashed. 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. The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. The default rule in prxyinfo ACL (as mentioned in part 4) is enabled if no custom ACL is defined. 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. Check the secinfo and reginfo files. Datenbankschicht: In der Datenbank, welche auf einem Datenbankserver liegt, werden alle Daten eines Unternehmens gesichert. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. 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. As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: 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]. 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. 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.
