Visually reminiscent of classic computer games such as The Sims and Sim City, Linxville?s first bitesize course to launch is Perimeter Security. It presents the student with a simulated environment containing a number of commercial buildings surrounded by roads, gates, fencing, lighting and security guards, which link back to the topic. The learner is taken on a guided interactive learning journey around the site and is presented with potential threat vulnerabilities.
