Command Description
18. See the Security
Satlink provides means of protection against unwanted
access. Password protection is at the heart of the security.
Whether accessing Satlink with a USB cable, an RS232
cable, via the Wi-Fi hotspot, through a USB thumb drive,
over Iridium SBD messages, over cell TCP/IP, or over cell
SMS messages, password protection guards access to
Satlink. In order to access Satlink, the correct password
must be provided.
For remote access over Cell, additional protection is
provided over TCP/IP via the use a VPN. To access Satlink,
one first connect to the appropriate VPN.
For Iridium access, additional protection is provided by the
Iridium system itself, which blocks access from
unauthorized sources. Anyone who seeks to send
messages to Satlink must be on a white list provided to
Iridium.
Each SMS message sent to Satlink needs to include the
password if Satlink is to process it. The same holds true for
Iridium SBD messages.
Satlink’s Wi-Fi hotspot provides an additional layer of
security. It uses WPA2-AES protection, meaning that a Wi-
Fi password must be provided to connect to the hotspot.
Additionally, the Wi-Fi hotspot is generally off until the site
is physically visited and the front panel button on Satlink is
pressed. Please note that Satlink’s Wi-Fi hotspot provides
access only on site. It does NOT make Satlink accessible
over the internet.
