What are the best option to do a firmware update on Teleworker phones
HungryHippo:
Is there another way beside the TFTP to update the firmware on teleworker phones?
lundah:
TFTP is it, the remote phone will download from the MBG it connects to.
HungryHippo:
wouldn't that protocol be unsecured? Is there a way for something like sftp or https setup on MBG to have the phones updated?
acejavelin:
What is your concern with the firmware using an unsecure protocol? The phone downloads the firmware and verifies the checksum before applying it, there isn't any real security concern here...
HungryHippo:
doesn't hackers usually use the tftp protocol to gain access to servers for this case which is the MBG server and why tftp is usually not considered safe to allow through the firewall.
