Application security & protocols

In Play Digital Signage, we take security of your data very seriously. This page gives a brief summary of the security procedures at Play Digital Signage

How is my web account secured?

Your passwords are stored in our database encrypted using an industry standard password hashing algorithm Bcrypt. This way, your passwords are not know to our staff and will not be compromised in the unlikely event of a data breach. Your login sessions are facilitated using Secure HTTPS-only cookies to eliminate the risk of eavesdropper stealing them by intercepting your connections.

Your web chat is managed by crisp.chat, yet another security conscious company.

How are my files secured?

Your files are hosted on Amazon S3 service, world’s most used file storage service. While we can not make the files private, because the players need to be able to download the files from the Internet, we generate a unique id for each file, so the URL is virtually impossible to guess. For an example this is the URL of an uploaded file:

https://s3.eu-central-1.amazonaws.com/infoscreen/944e6dab-76a2-4785-b913-c7966ad14ad8/a2cf019b-cb83-4192-b4fe-83827f481be0.png

An attacker has better chances of guessing your password! (so make sure it’s secure)

How secure are communications?

All connections to our servers are HTTPS, that means that the traffic is encrypted, that includes web-socket connections.

The Internet traffic is routed through Cloudflare network, which protects our servers against Denial Of Service (DoS) and brute force attacks.

How are players secured?

When a player is linked to a user account, the server generates a unique secret token that is sent to the player once. Every subsequent request made by the player to our servers requires the token to be present in order to prevent malicious attacker from impersonating as the player itself. The weakest link is the physical player security, so make sure it’s out of sight and if possible, then out of reach!

Where is my credit card information stored?

We use Stripe as our payment gateway and they take care of storing your information securely. Stripe is PCI Data Security Standard certified company.

Which external services the players connect to?

In case the player is behind a corporate firewall, you need to white-list following domains:

  • playsignage.com
  • We recommend whitelisting all subdomains of *.playsignage.com to be future-proof. If wildcard white-listing is not possible, then the player may also use following sub-domains:
    • release.playsignage.com (only for Windows / OSX / Linux players to auto-update)
    • quotes.playsignage.com (Quote plugin is using this endpoint to fetch quotes)
    • onthisday.playsignage.com (Today In History plugin is using this endpoint to fetch data)
    • proxy.playsignage.com (Weather, Facebook and Instagram plugin use this domain)
    • my.playsignage.com (Location of proxy used to fetch insecure non-HTTPS web resources)
    • logging.playsignage.com (Optional, for us to receive player logs and help us debug issues)
  • s3.eu-central-1.amazonaws.com
  • images.unsplash.com (When using images from the Unsplash plugin)
