This section provides a general overview of security for SD cards.
Physical Security
If you plan to use a Micro SD microSD card, you can use the physical card cover that goes over the SD card slot to increase security. If you need additional physical security, an SSD can be a better option since you must open the case to access the SSD drive.
Asset Security
BrightSign supports optional content and script encryption to make your SD card readable only on the player, as well as secure boot. You also have the option to disable external (SD, USB) storage.
Malware/Virus Protection
To avoid malware:
Use the card cover on your SD card or an SSD drive
Keep your firmware updated to get the latest security fixes
When transferring data between devices, use secure connections such as USB cables or trusted wireless connections. Avoid connecting to unknown or unsecured Wi-Fi networks.
