An outdoor LED screen is a computer-driven device. It retains therefore all the advantages and shortcomings of the installed software. The absolute majority of outdoor LED screens (especially those manufactured in China) are controlled by standard Microsoft programs which are rather vulnerable to hackers’ attacks. A specialist needs only to invest a certain amount of time and efforts to hack a website of some company or institution. However most such attacks remain anonymous and unseen. To gain access to a public LED screen makes much more sense since the results are clear for everyone to see.
In the past various video blogs ran articles on big screen hacking. For example, in 2007 a large LED screen in the very center of Moscow that belonged to CityVision was reported to have been successfully hacked. However, this proved to be a clever video simulation allegedly provided by competitors. Current case with indecent video on outdoor LED screens is no such fake but an unpleasant reality. What can be done to withstand further attacks?
Solution
It is possible to prevent unauthorized access to remote network stations (in our case, outdoor LED screens). Moscow committee on advertising was fast to announce that it plans to strengthen safety of informational channels to all outdoor LED screens in Moscow to avoid further embarrassment. The easiest way to stop attacks on outdoor screens is to force screen operators to download content using only local networks, as it used to be done a few years ago when this technology was new and immature.
Generally, a simple and safe control system can be easily created so that any unauthorized access will be impossible. For example, video screens installed in stadiums are generally well-protected, they are manually controlled at all times and the data is transferred via the local network. But the data transfer to remote locations via the Internet is based on other principles.
Whatever safety measures are taken, the flexibility of control and instant data transfer functions in the informational LED screen networks must be protected at all costs.
The outdoor screens must be supplied with the foolproof control systems capable of preventing attempts at hacking the system and offering operators reliable real-time communication protocols with screens from a control center. LED screens remain an expensive item and it’s silly to save pennies on a control system that may turn to be a weak link of this sophisticated technology
