Security, or rather lack thereof, has been a hot topic lately in the digital world. With the WannaCry ransomware running amock across the globe and our favourite rum-loving pirate’s latest instalment being held captive by hackers, it is an ideal time to make sure that you have an ironclad digital security plan in place.
This is especially important for digital signage network security. With some screens reaching thousands of people at a given time, even a minute of unauthorized content can cause major headaches.
Controlling access to your systems is a multi-layer effort with physical access, OS maintenance and application security all being important aspects of a more hacker-resistant system.
As most screens are located in public areas, it wouldn’t take a high-level hacker to change the content on your screens. Rather, someone could simply walk up right up, unplug your player and replace it with their own.
Therefore, the first step to make sure your network is secure is to restrict physical access to the network’s devices.
Without physical access to the screen, hackers must find a virtual backdoor into the system. However, be sure not to leave these doors wide open for them. With simple yet effective measures in place, access to your OS will be very limited.
The goal of locking down the OS is to only run services the player will actually need. The removal of these services gives the would-be hackers less to attack and will encourage them to move onto an easier target.
This will also benefit the player other ways. Less running services increases performance and reduces unnecessary software maintenance.
Your digital signage application is the heart of your player, managing playback and reporting. However, it adds another layer that must be secured. Data can be intercepted as it travels over the network and can be seen by possible hackers if not properly secured.
Even if physical access to your digital signage network is restricted and strong measures are in place to protect your OS from attacks, your network may still be at risk due to third party applications. Selecting partners that hold security to the highest standards is critical to your network operations strategy.
Now that you have all the know-how, it’s time to audit your digital signage network security strategy. Are you protected from unwanted takeovers?
You can start with a basic security scan. If any of these ports are open, it might be time to reconsider your strategy.
Carefully considering the physical setup of your screens and players, protecting your OS and working with security-savvy application vendors are the three steps to take to secure your network.
