Abstract
The interest of the educational community in the laboratory- (lab) based education has grown steadily. As remote labs have started to be a reliable alternative to traditional hands-on labs, security and safety issues are becoming increasingly important, as their interconnected nature raises new and challenging issues. The complexity increases when multiple institutions are involved in a federated lab infrastructure. This paper provides a guideline for assessing safety and security in federated labs following the VDI/VDE 2182 guideline and verifies the concept based on remote labs in three different academic institutions.

Introduction and ContextRecently remote and virtual labs have started to be a reliable alternative to traditional hands-on laboratories
They made use of a software solution to provide the security of machinery within their remote bench for testing electrical machine based on Easy Java Simulation (EJS) to connect the real hardware to the user interface for controlling (i) the load voltage and frequency when the machine is connected to the load in an islanded way, and (ii) the active and reactive power injected to the net when the machine is directly connected
We have focused on lab managers, as they will be in charge of implementing corresponding safety and security measures Fig 1
Summary
Remote and virtual labs have started to be a reliable alternative to traditional hands-on laboratories. Federated remote labs including multiple independent institutions and network structures are yet increasing the security risks involved. Security issues in the “virtual world” can cause harm in the “physical world” It is eminent, that safety and security for remote labs need to be tackled in a joint approach. This paper continues this work and verifies the theoretical approach by prototypically applying VDI/VDE 2182 in three different labs currently involved in the DigiLab4U network, described in section/chapter 4. This must be seen as an iterative approach that needs to address future changes and additions to the federated lab network.
