What is Digital Signage?

The Threat Beneath a Connected World: Digital Signage Cybersecurity Concerns and their Implications on Business and Public Security

Digital Signage refers to a sub-segment of signage that uses digital technology for display purposes. Typically seen in stores, restaurants, corporate buildings, airports, and other public spaces, digital signage employs monitors, LEDs, or projection to share targeted information, advertisements, and important messages. But, as we ascend further into the era of digital transformation, cybersecurity has become a salient issue for digital signage too.

Digital Signage falls under the larger umbrella of the Internet of Things (IoT), referring to the growing network of physical devices connected to the internet for data exchange. Since digital signage devices are often interconnected, they can potentially become an access point for unauthorized users intending to infiltrate your network, making them a cyber vulnerability. Consequently, focusing on safeguarding digital signage from potential security threats has become a necessitous measure.

The challenge of cybersecurity within digital signage is multifaceted, starting with the fact that many organizations, willingly or unwillingly, overlook the security of digital signage. Often organizations are not even aware that their digital signage is vulnerable to cyber threats, and that failure to protect them might lead to a breach in their network security.

An example of digital signage threats is the infamous cybersecurity incident in 2015 when a hacker played a two-minute inappropriate/offensive clip on digital signage screens in a Union Station concourse, emphasizing an urgent need for thorough digital signage protection measures. Digital systems, be it signs, computers, or other devices, without a resilient firewall and up-to-date security measures are prone to such invasions and absolutely need protection.

One effective strategy to combat this security issue is deploying antivirus software that can handle threats appropriately. Antivirus software scans the digital environment for familiar threats, isolating and eliminating them to prevent network infection. It requires regular updates to perfect its virus signatures and boost its capabilities in virus detection and eradication, which means staying updated with the latest information from cybersecurity resources is essential.

In terms of hardware, digital signage must employ robust security measures. Password-protected accounts should be used, ensuring they remain private and frequently changing them to reduce any potential risks. Hosting digital signage on a Virtual Private Network (VPN) can ensure safe and encrypted communication over the network.

Secure Sockets Layer (SSL) certificates on websites can allow data to be transferred over a secure network, keeping the information encrypted and maintaining its integrity. firewall protection can keep harmful incoming traffic out while enabling user-friendly access for administrators.

On a different note, backend digital signage systems can also be targeted by cyberacters. Therefore, maintaining robust and up-to-date antivirus software is important to safeguard underlying IT infrastructure.

As digital signage involves uploading and updating content frequently, their management interfaces can be targeted by phishing attacks or attempts to infiltrate login credentials. Therefore, employees handling these interfaces should be trained in basic cybersecurity practices. If there's a need to access content management systems on unknown networks, VPNs should be employed to establish a secure connection.

A noteworthy aspect of digitalizing is educating users on the risks and encouraging them to contribute to cybersecurity. Comprehensive staff training to enable detection of suspicious activities, understanding malware and phishing scams, and implementing necessary preventive measures is key to fortifying digital signage security.

To sum up, with increased digitalization, the importance of cybersecurity sectors, including digital signage, has amplified significantly. While creating digital signage adds a sophisticated touch in delivering content to the targeted audience, overlooking their cybersecurity can potentially open gates for critical data breaches. Safeguarding these systems with antivirus software, network protection measures, and staff education must be top priorities. As digital signage continues to evolve, so should its security necessary to ensure it serves its intended purpose without incurring irreversible damages.
