reginfo and secinfo location in sap

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. Part 6: RFC Gateway Logging I think you have a typo. 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! Then the file can be immediately activated by reloading the security files. Most of the cases this is the troublemaker (!) Please note: SNC User ACL is not a feature of the RFC Gateway itself. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. 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. 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. There are two different syntax versions that you can use (not together). The order of the remaining entries is of no importance. The reginfo ACL contains rules related to Registered external RFC Servers. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . The first letter of the rule can be either P (for Permit) or D (for Deny). You must keep precisely to the syntax of the files, which is described below. In SAP NetWeaver Application Server ABAP: Every Application Server has a built-in RFC Gateway. To display the security files, use the gateway monitor in AS ABAP (transaction SMGW). They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. Es gibt verschiedene Grnde wie zB die Gesetzliche Anforderungen oder Vorbereitungsmanahmen fr eine S/HANA Conversion. The secinfo file has rules related to the start of programs by the local SAP instance. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. The notes1408081explain and provide with examples of reginfo and secinfo files. Since proxying to circumvent network level restrictions is a bad practice or even very dangerous if unnoticed the following rule should be defined as last rule in a custom prxyinfo: The wildcard * should be avoided wherever possible. The local gateway where the program is registered can always cancel the program. 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). There are other SAP notes that help to understand the syntax (refer to the Related notes section below). This publication got considerable public attention as 10KBLAZE. Part 7: Secure communication 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. You can make dynamic changes by changing, adding, or deleting entries in the reginfo file. Alerting is not available for unauthorized users. In case you dont want to use the keyword, each instance would need a specific rule. So lets shine a light on security. This is because the rules used are from the Gateway process of the local instance. 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. 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. The network service that, in turn, manages the RFC communication is provided by the RFC Gateway. 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. Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. Part 5: ACLs and the RFC Gateway security 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. This means the call of a program is always waiting for an answer before it times out. secinfo: P TP=* USER=* USER-HOST=* HOST=*. 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. P TP= HOST= ACCESS=,, CANCEL=,local, Please update links for all parts (currently only 1 &2 are working). 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. 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. This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. Fr die gewnschten Registerkarten "Gewhren" auswhlen. 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. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. 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). Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. Part 4: prxyinfo ACL in detail. The RFC Gateway hands over the request from the RFC client to the dispatcher which assigns it to a work process (AS ABAP) or to a server process (AS Java). 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. All other programs starting with cpict4 are allowed to be started (on every host and by every user). IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. 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 production systems, generic rules should not be permitted. Part 4: prxyinfo ACL in detail In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. 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. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. 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. Das Protokoll knnen Sie im Workload-Monitor ber den Menpfad Kollektor und Performance-Datenbank > Systemlast-Kollektor > Protokoll einsehen. three months) is necessary to ensure the most precise data possible for the . Part 3: secinfo ACL in detail. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. Of course the local application server is allowed access. The tax system is running on the server taxserver. The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. 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). Save ACL files and restart the system to activate the parameters. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo If we do not have any scenarios which relay on this use-case we are should disable this functionality to prevent from misuse by setting profile parameter gw/rem_start = DISABLED otherwise we should consider to enforce the usage of SSH by setting gw/rem_start = SSH_SHELL. where ist the hint or wiki to configure a well runing gw-security ?

Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. 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. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS).Before jumping to the ACLs themselves, here are a few general tips: A general reginfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): Usually, ACCESS is a list with at least all SAP servers from this SAP system. so for me it should only be a warning/info-message. Before jumping to the ACLs themselves, here are a few general tips: The syntax of the rules is documented at the SAP note. BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . Evaluate the Gateway log files and create ACL rules. 2. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. 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. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. The Solution Manager (SolMan) system has only one instance, running at the host sapsmci. 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.
