Security is important in computer networks. Network security is the task of the Administrator, where the administrator is responsible for data security on the network. The problem that is often faced by a network administrator is the laboratory as a test site of network design that has been created without interrupting the running system. Testing laboratories are needed by the administrator as a test site for network design, before implementing the design on a real network system. In this research, the researchers propose a method to solve the problem of testing the computer network, through the approach of using virtual machine by creating virtual laboratory. This virtual laboratory allows an administrator to quickly reset the configuration without interrupting the system that has been running. The virtual laboratory is based on UML (User Mode Linux) virtualization technology using Netkit emulators. The researchers verified the experiment through a simulation based on firewall network security design trial scenarios that have been created using the Netkit emulator. The results of trials in a virtual laboratory show the similarity of the working environment to a real network system. It can be concluded that the Netkit emulator is able to run test scenarios and firewall commands on network security properly. © Published under licence by IOP Publishing Ltd.
