reginfo and secinfo location in sap

secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. Now 1 RFC has started failing for program not registered. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Click more to access the full version on SAP for Me (Login . 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. (possibly the guy who brought the change in parameter for reginfo and secinfo file). 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. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Reread . 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. Die erstellten Log-Dateien knnen im Anschluss begutachtet und daraufhin die Zugriffskontrolllisten erstellt werden. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. In SAP NetWeaver Application Server ABAP: Every Application Server has a built-in RFC Gateway. 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. Part 3: secinfo ACL in detail Limiting access to this port would be one mitigation. The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. The reginfo file has the following syntax. 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. Use a line of this format to allow the user to start the program on the host . Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). 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. Despite this, system interfaces are often left out when securing IT systems. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. 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). 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. SMGW-->Goto -->External Functions --> External Security --> Maintenance of ACL files --> pop-up is shown as below: "Gateway content and file content for reginfo do not match starting with index " (xx is the index value shown in the pop-up), Gateway, Security, length, line, rule, limit, abap , KBA , BC-CST-GW , Gateway/CPIC , Problem. This could be defined in. The RFC Gateway is capable to start programs on the OS level. Giving more details is not possible, unfortunately, due to security reasons. The Gateway is a central communication component of an SAP system. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. Hello Venkateshwar, thank you for your comment. Privacy | 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). if the server is available again, this as error declared message is obsolete. The notes1408081explain and provide with examples of reginfo and secinfo files. The local gateway where the program is registered always has access. The RFC library provides functions for closing registered programs. 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. If no access list is specified, the program can be used from any client. 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. Please make sure you have read at least part 1 of this series to be familiar with the basics of the RFC Gateway and the terms i use to describe things. CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. 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. A combination of these mitigations should be considered in general. You can define the file path using profile parameters gw/sec_info and gw/reg_info. 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 I think you have a typo. E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* 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. 2.20) is taken into account only if every comma-separated entry can be resolved into an IP address. The local gateway where the program is registered can always cancel the program. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. 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 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. Save ACL files and restart the system to activate the parameters. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. 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 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. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. Program cpict4 is allowed to be registered if it arrives from the host with address 10.18.210.140. Hufig ist man verpflichtet eine Migration durchzufhren. 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. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. 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). The order of the remaining entries is of no importance. Part 5: Security considerations related to these ACLs. Refer to the SAP Notes 2379350 and2575406 for the details. File reginfocontrols the registration of external programs in the gateway. The RFC Gateway does not perform any additional security checks. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. 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 ). Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. Part 4: prxyinfo ACL in detail. Program hugo is allowed to be started on every local host and by every user. 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. This is defined in, how many Registered Server Programs with the same name can be registered. Programs within the system are allowed to register. Part 5: ACLs and the RFC Gateway security. The wildcard * should not be used at all. To set up the recommended secure SAP Gateway configuration, proceed as follows:. Always document the changes in the ACL files. Part 7: Secure communication An example could be the integration of a TAX software. 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. 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. 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. 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. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. 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. three months) is necessary to ensure the most precise data possible for the connections used. The following syntax is valid for the secinfo file. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. 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). This order is not mandatory. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. 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. This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. Configuring Connections between SAP Gateway and External Programs Securely, SAP Gateway Security Files secinfo and reginfo, Setting Up Security Settings for External Programs. 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. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. 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? Read more. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. 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. 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 other words, the SAP instance would run an operating system level command. Add a Comment Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Part 2: reginfo ACL in detail 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]. Use host names instead of the IP address. The wildcard * should be strongly avoided. Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted.
