Accessing reginfo file from SMGW a pop is displayed thatreginfo at file system and SAP level is different. No error is returned, but the number of cancelled programs is zero. Each instance can have its own security files with its own rules. Its functions are then used by the ABAP system on the same host. 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. You have configured the SLD at the Java-stack of the SolMan system, using the RFC Gateway of the SolMans ABAP-stack. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. 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. 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. If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* The reginfo file has the following syntax. The first letter of the rule can be either P (for Permit) or D (for Deny). All of our custom rules should bee allow-rules. 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]. This means the call of a program is always waiting for an answer before it times out. It also enables communication between work or server processes of SAP NetWeaver AS and external programs. The order of the remaining entries is of no importance. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. 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. 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. All subsequent rules are not checked at all. The local gateway where the program is registered always has access. The related program alias also known as TP Name is used to register a program at the RFC Gateway. To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. Program hugo is allowed to be started on every local host and by every user. If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. 2. Part 8: OS command execution using sapxpg. RFCs between two SAP NetWeaver AS ABAP systems are typically controlled on network level only. *. 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). The following syntax is valid for the secinfo file. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. 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. Only the first matching rule is used (similarly to how a network firewall behaves). 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. ABAP SAP Basis Release as from 7.40 . If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. In these cases the program alias is generated with a random string. HOST = servername, 10. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. Specifically, it helps create secure ACL files. Each line must be a complete rule (rules cannot be broken up over two or more lines). 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. 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. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. 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. Of course the local application server is allowed access. In production systems, generic rules should not be permitted. This is defined in, how many Registered Server Programs with the same name can be registered. If the TP name itself contains spaces, you have to use commas instead. 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. Always document the changes in the ACL files. 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 Part 6: RFC Gateway Logging The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. To permit registered servers to be used by local application servers only, the file must contain the following entry. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. The secinfosecurity file is used to prevent unauthorized launching of external programs. File reginfo controls the registration of external programs in the gateway. Limiting access to this port would be one mitigation. 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). Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. Haben Support Packages in der Queue Verbindungen zu Support Packages einer anderen Komponente (weitere Vorgngerbeziehung, erforderliches CRT) wird die Queue um weitere Support Packages erweitert, bis alle Vorgngerbeziehungen erfllt sind. This list is gathered from the Message Server every 5 minutes by the report RSMONGWY_SEND_NILIST. 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. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Part 4: prxyinfo ACL in detail. 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. There may also be an ACL in place which controls access on application level. Use host names instead of the IP address. Access attempts coming from a different domain will be rejected. This order is not mandatory. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. With secinfo file this corresponds to the name of the program on the operating system level. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. For this reason, as an alternative you can work with syntax version 2, which complies with the route permission table of the SAProuter. If the Gateway protections fall short, hacking it becomes childs play. This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). Thank you! Then the file can be immediately activated by reloading the security files. P TP=* USER=* USER-HOST=internal HOST=internal. 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. Ergebnis Sie haben eine Queue definiert. 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 1: General questions about the RFC Gateway and RFC Gateway security. The SAP note1689663has the information about this topic. Depending on the settings of the reginfo ACL a malicious user could also misuse this permissions to start a program which registers itself on the local RFC Gateway, e.g.,: Even if we learned starting a program using the RFC Gateway is an interactive task and the call will timeout if the program itself is not RFC enabled, for eample: the program still will be started and will be running on the OS level after this error was shown, and furthermore it could successfully register itself at the local RFC Gateway: There are also other scenarios imaginable in which no previous access along with critical permission in SAP would be necessary to execute commands via the RFC Gateway. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). Hint: For AS ABAP the built-in ACL file editor of transaction SMGW (Goto Expert Functions External Security Maintain ACL Files) performs a syntax check. 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. Furthermore the means of some syntax and security checks have been changed or even fixed over time. . To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Reread . 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. To set up the recommended secure SAP Gateway configuration, proceed as follows:. 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. Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. We can identify these use cases by going to transaction SMGW -> Goto -> Logged on Clients and looking for lines with System Type = Registered Server and Gateway Host = 127.0.0.1 (in some cases this may be any other IP address or hostname of any application server of the same system). Somit knnen keine externe Programme genutzt werden. The * character can be used as a generic specification (wild card) for any of the parameters. If the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. This opensb the Gateway ACL Editor, where you can display the relevant files.. To enable system-internal communication, the files must contain the . This makes sure application servers must have a trust relation in order to take part of the internal server communication. Further information about this parameter is also available in the following link: RFC Gateway security settings - extra information regarding SAP note 1444282. Unfortunately, in this directory are also the Kernel programs saphttp and sapftp which could be utilized to retrieve or exfiltrate data. This way, each instance will use the locally available tax system. File reginfocontrols the registration of external programs in the gateway. The RFC Gateway can be used to proxy requests to other RFC Gateways. 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. Part 5: ACLs and the RFC Gateway security. Alerting is not available for unauthorized users, Right click and copy the link to share this comment. Every line corresponds one rule. Check out our SAST SOLUTIONS website or send us an e-mail us at sast@akquinet.de. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. Terms of use |
In the following i will do the question and answer game to develop a basic understanding of the RFC Gateway, the RFC Gateway security and its related terms. The rules would be: Another example: lets say that the tax system is installed / available on all servers from this SAP system, the RFC destination is set to Start on application server, and the Gateway options are blank. There are two different syntax versions that you can use (not together). 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. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. The syntax used in the reginfo, secinfo and prxyinfo changed over time. In a pure Java system, one Gateway is sufficient for the whole system because the instances do not use RFC to communicate. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). Remember the AS ABAP or AS Java is just another RFC client to the RFC Gateway. For example: The SAP KBAs1850230and2075799might be helpful. A custom allow rule has to be maintained on the proxying RFC Gateway only. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. 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. Access to this ports is typically restricted on network level. The RFC Gateway is capable to start programs on the OS level. Part 2: reginfo ACL in detail. D prevents this program from being started. All subsequent rules are not even checked. 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. 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. The Gateway uses the rules in the same order in which they are displayed in the file. Please make sure you have read part 1 4 of this series. 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. 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. You have a non-SAP tax system that needs to be integrated with SAP. Sobald dieses Recht vergeben wurde, taucht die Registerkarte auch auf der CMC-Startseite wieder auf. RFC had issue in getting registered on DI. Please note: The proxying RFC Gateway will additionally check its reginfo and secinfo ACL if the request is permitted. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. Please note: SNC System ACL is not a feature of the RFC Gateway itself. Part 3: secinfo ACL in detail. This means that the sequence of the rules is very important, especially when using general definitions. 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. 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 blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. Part 3: secinfo ACL in detail. As separators you can use commas or spaces. This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. Someone played in between on reginfo file. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. 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. Part 8: OS command execution using sapxpg. 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. It is important to mention that the Simulation Mode applies to the registration action only. This is a list of host names that must comply with the rules above. How to guard your SAP Gateway against unauthorized calls, Study shows SAP systems especially prone to insider attacks, Visit our Pathlock Germany website https://pathlock.com/de/, Visit our Pathlock Blog: https://pathlock.com/de/blog/, SAST SOLUTIONS: Now member of Pathlock Group. About item #1, I will forward your suggestion to Development Support. We should pretend as if we would maintain the ACLs of a stand-alone RFC Gateway. 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. This diagram shows all use-cases except `Proxy to other RFC Gateways. If this addition is missing, any number of servers with the same ID are allowed to log on. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo This is an allow all rule. If no access list is specified, the program can be used from any client. Please note: SNC User ACL is not a feature of the RFC Gateway itself. While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. 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. 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. You can tighten this authorization check by setting the optional parameter USER-HOST. For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS). It registers itself with the program alias IGS. at the RFC Gateway of the same application server. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. 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. A rule defines. In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. An example could be the integration of a TAX software. Click more to access the full version on SAP for Me (Login . 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. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. Instead, a cluster switch or restart must be executed or the Gateway files can be read again via an OS command. This also includes the loopback address 127.0.0.1 as well as its IPv6 equivalent ::1. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. The name of the registered program will be TAXSYS. Beachten Sie, da der SAP Patch Manager die Konfiguration Ihres SAP-Systems bercksichtigt und nur solche Support Packages in die Queue aufnimmt, die in Ihr System eingespielt werden drfen. Falls Sie danach noch immer keine Anwendungen / Registerkarten sehen, liegt es daran, dass der Gruppe / dem Benutzer das allgemeine Anzeigenrecht auf der obersten Ebene der jeweiligen Registerkarte fehlt. But also in some cases the RFC Gateway itself may 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. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). 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. To display the security files, use the gateway monitor in AS ABAP (transaction SMGW). Privacy |
After an attack vector was published in the talk SAP Gateway to Heaven from Mathieu Geli and Dmitry Chastuhin at OPDCA 2019 Dubai (https://github.com/gelim/sap_ms) the RFC Gateway security is even more important than ever. Read more. Host Name (HOST=, ACCESS= and/or CANCEL=): The wildcard character * stands for any host name, *.sap.com for a domain, sapprod for host sapprod. To edit the security files,you have to use an editor at operating system level. The default configuration of an ASCS has no Gateway. Registered Server Programs at a standalone RFC Gateway may be used to integrate 3rd party technologies. You can also control access to the registered programs and cancel registered programs. The parameter is gw/logging, see note 910919. TP is a mandatory field in the secinfo and reginfo files. After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. Sie knnen anschlieend die Registerkarten auf der CMC-Startseite sehen. 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. This is because the rules used are from the Gateway process of the local instance. This page contains information about the RFC Gateway ACLs (reginfo and secinfo files), the Simulation Mode, as well as the workflow showing how the RFC Gateway works with regards to the ACLs versus the Simulation Mode. Part 7: Secure communication Legal Disclosure |
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. Somit knnen keine externe Programme genutzt werden. Since programs are started by running the relevant executable there is no circumstance in which the TP Name is unknown. Configuring Connections between SAP Gateway and External Programs Securely, SAP Gateway Security Files secinfo and reginfo, Setting Up Security Settings for External Programs. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. This could be defined in. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. Part 8: OS command execution using sapxpg. The location of this ACL can be defined by parameter gw/acl_info. IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. If no cancel list is specified, any client can cancel the program. Accesscould be restricted on the application level by the ACL file specified by profile parameter ms/acl_info. 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 secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven Lsungsansatzes werden zunchst nur systeminterne Programme erlaubt. The message server port which accepts registrations is defined by profile parameter rdisp/msserv_internal. So lets shine a light on security. You have an RFC destination named TAX_SYSTEM. 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. It seems to me that the parameter is gw/acl_file instead of ms/acl_file. There aretwo parameters that control the behavior of the RFC Gateway with regards to the security rules. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo If the option is missing, this is equivalent to HOST=*. The reginfo ACL contains rules related to Registered external RFC Servers. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). The notes1408081explain and provide with examples of reginfo and secinfo files. Maybe some security concerns regarding the one or the other scenario raised already in you head.
