reginfo and secinfo location in sap

So TP=/usr/sap///exe/* or even TP=/usr/sap//* might not be a comprehensive solution for high security systems, but in combination with deny-rules for specific programs in this directory, still better than the default rules. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. where ist the hint or wiki to configure a well runing gw-security ? 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. Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems. 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. Alerting is not available for unauthorized users. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. TP is restricted to 64 non-Unicode characters for both secinfo and reginfo files. 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 Access attempts coming from a different domain will be rejected. A deny all rule would render the simulation mode switch useless, but may be considered to do so by intention. In case the files are maintained, the value of this parameter is irrelevant; gw/sim_mode: activates/deactivates the simulation mode (see the previous section of this WIKI page). 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. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. All other programs from host 10.18.210.140 are not allowed to be registered. secinfo: P TP=* USER=* USER-HOST=* HOST=*. 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. Environment. It seems to me that the parameter is gw/acl_file instead of ms/acl_file. 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. All of our custom rules should bee allow-rules. Part 3: secinfo ACL in detail. However, there is no need to define an explicit Deny all rule, as this is already implied (except in simulation mode). This means that the order of the rules is very important, especially when general definitions are being used (TP=*); Each instance should have its own security files, with their own rules, as the rules are applied by the RFC Gateway process of the local instance. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. 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). 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). This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). The local gateway where the program is registered can always cancel the program. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. Its location is defined by parameter 'gw/reg_info'. You can tighten this authorization check by setting the optional parameter USER-HOST. To overcome this issue the RFC enabled program SAPXPG can be used as a wrapper to call any OS command. The location of this ACL can be defined by parameter gw/acl_info. 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. 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. In other words, the SAP instance would run an operating system level command. Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. Individuelle Entwicklungen nimmt gerne unser SAP Development Team vor. 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. 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. 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. Please follow me to get a notification once i publish the next part of the series. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. If the Gateway protections fall short, hacking it becomes childs play. (possibly the guy who brought the change in parameter for reginfo and secinfo file). 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 Gateway uses the rules in the same order in which they are displayed in the file. Part 8: OS command execution using sapxpg. In these cases the program alias is generated with a random string. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). Danach wird die Queue neu berechnet. In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. To mitigate this we should look if it is generated using a fixed prefix and use this as a pattern with an ending wildcard in order to reduce the effective values, e.g., TP=Trex__*, which would still be better than TP=*`. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. This is a list of host names that must comply with the rules above. 2. After reloading the file, it is necessary to de-register all registrations of the affected program, and re-register it again. 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. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. All subsequent rules are not checked at all. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. 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. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. The reginfo ACL contains rules related to Registered external RFC Servers. Part 6: RFC Gateway Logging. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. Part 6: RFC Gateway Logging 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. I think you have a typo. Read more.
