How to Create a Secure Digital Signage Network in 3 Steps


Digital signage network devices, just like any other machines that are a part of a network, are at risk 24/7 and can be attacked and corrupted at any given time. There are myriad of things that expose networks to substantial security risks: hackers, pirates, viruses, worldwide cyber attacks, etc..

Given the challenges and risks, there are some common sense solutions anyone can take for a digital signage network. For example, carrying out a proper audit and assessing the risks for your network, enabling all of the security features, placing your server in a secure place, using guard passwords and firewalls, opting for reliable tandems like  historically safe and secure Apple media player + KItcast DS software (read more at: https://Kitcast.tv), etc. Though some precautions are way more important, we have 3 simple steps you can take to enhance your digital signage security, but first lets start with pre-step, the common sense one.

The Common Sense Step: Start with a risk assessment to enhance digital signage security

Carrying out a detailed security review is the absolutely necessary first step: assessing what you are using to minimize the risks, checking for updates, latest versions of software, the best encryption to protect your network, etc. A simple check-list for the best practices is the best way to go about creating and maintaining a secure digital signage network. You can adjust the list specifically for your company, though, ultimately, we recommend practicing with the following:

  1. Assess and, if necessary, improve the physical security of media players.
  2. Follow good network safety practices.
  3. Set the dates for changing the passwords, preferably they need to be changed every six months.
  4. Hire an outside firm to test the vulnerability of your network for better risks assessment.
  5. Regularly run system scans and use both virusand spyware protection program.
  6. Check whether the latest versions of the software are installed.
  7. Always use hardware and software firewalls.
  8. For the user authentication always use multiple layers.
  9. Use the best encryption system.

Step 1:  Protect the physical access to your digital signage media players 

Though often overlooked and commonly neglected, proper physical precautions are vital. The top-of-the-line hacker-proof system won’t help you if there is a way to replace your content by simply switching the media player. Your digital signage players need to be installed in a protected and monitored place with very restricted access given only to those who need it, meaning your step 1 is restricting the physical access to all of the players that make up your company’s network.

Start by making sure that there’s a protocol in place for all of your screens and media player installments. There should be strict, easy-to-follow guidelines that include competent securing all of the screens, making sure they aren’t easily dismantled. Your digital signage media players should not be visible and ideally, there shouldn’t be a way to access them, they need to be locked. It goes without saying that all ports and connections need to be secured.

Step 2: Restrict access to your Operating System

Seriously limited access to the OS equals creating a secure digital signage network. You need to focus on the applications and services that are necessary for the OS. All deemed unimportant should be disabled. Removal of additional services means lower memory utilization, fever viruses and breaches, and narrower attack footprint, make sure that open inbound ports aren’t necessary for your software. As mentioned above, all of the security measures should be updated and checked on a regular basis.

Additionally, your system of reporting security problems should be very advanced and intelligent enough to detect a security breach.

Step 3: Pay additional attention to the application security

Third party applications pose a risk to the overall security of your DS network. Application assess can be restricted by avoiding insecure protocols (FTP, HTTP), use of applications with SSL certificates or, better yet, their own encryptions. Cooperate with those that hold similar values towards safety and security, with companies that take additional security measures and religiously follow safety guidelines.
