Configurations
Workarounds

BrightSign recommends the following security practices: * Change default passwords when the device is initially set up. * Disable the local DWS as described in "High Security settings". * Disable the SSH/telnet server when not being used - it is not enabled by default. * Devices should be located where an attacker does not have physical access to the device. * SD and USB ports can be disabled if not needed. For more information, please contact BrightSign via their website. https://www.brightsign.biz/contact-us/
