This blog will discuss some possible benefits of industrial machine data as part of business and operational intelligence strategy. Homework help but make it clear it's homework Splunk has recently partnered with Kepware to harness data from the Industrial Internet of Things (IIoT).Note that for OPC DA, this is managed under anonymous clients.This sub is dedicated to discussion and questions about Programmable Logic Controllers (PLCs): "an industrial digital computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis." On topic subjects In conclusion, by performing the correct user and manager, coupled with Security Policies, we can control what is exposed based on users. Observe that when you browse the nodes, DeviceB is not visible Validating the access permission via UAEXpertįor the purpose of this document, we will not go through the mechanisms of the UAEXpert. Under browsing, select the custom permissions and deny accordingly.Ĭlick Apply and close the window. To complete the picture, we will also deny seeing the device (browsing). Right click DeviceB and select No access. In our use case, we will simply deny DeviceB to GroupA. Now you may control the access to each I/O Tags either at a device layer or the tag layer. Under GroupA select I/O Tags by clicking the Arrow: Under Security Policies, notice that all of the other permissions are locked by default. Under user manager, right click on GroupA > Properties. For our use case, we will allow them to read and browse the respective device. We will use the security policies to allow UserA to access DeviceA only and UserB to access DeviceB only.īy default, the permissions created for a new group are all denied. In our case, suppose we have two devices, groupA and groupB. If you expand the group, you can now fine-tune the permission. Swap the view to Security Policies and you should now see the updated new groups. Right click the administration tool and go to settings. To do so, right click on the group and click Add User…Ĭlose the window Step 3: Setting the permissions via Security Policies plugin For example, GroupA will be able to see a particular tag while GroupB will see another set of tagsĬreate the respective users under the groups, for example, UserA and UserB. Step 2: Create the necessary user groups and usersĬreate the group and users as you will like. KEPServerEX and Thingworx Kepware Server are more than OPC servers they are interoperable connectivity platforms for industrial automation and IoT. Be sure to take note of any active UA client connection and notify the stakeholders as this will cause them to disconnect once applied. Important: This applies across the board for the OPC UA interface. Under OPC UA > Set Allow Anonymous login to no.
The setting is found under Right click on Projects > Properties By default, this option is disabled in Kepware and should remain so if you wish to leverage the security policy plugin. Typically in most scenario, if your vendor asks you to login without any user name of password, they are under the anonymous login. In OPC UA as a client, you have the ability to connect to the remote OPC Server either using anonymous login or with an authentication. Architecture view of guide Step 1: Disable Anonymous logins
The document will guide the user on a case where we segregate DeviceA for UserA and DeviceB for UserB via the use of the security policy and authenticated logins. It can be referenced as one of the recommended steps in 6.1 OPC UA from our secured deployment guide:
Note that this document focuses on using the functions for OPC UA. This feature can be achieved by using the security policy plugin in KEPServerEX v6 and above. For example, you may be the engineer who connected the industrial assets and needs to share some data to the analytics team but will like to reduce confusion by showing them only what is required to them. A typical situation that requires the use of such a manner is typically a scenario where you have multiple tenants or stakeholders who are connected and serviced via the same KEPServerEX.
