8 Security
XLink provides means of protection against unwanted access. Password protection is at the heart of the
security.
Whether accessing the station with a USB cable, an RS-232 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 the station. To access the station, 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 the
station, one first connects 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 the station must be on a whitelist provided
to Iridium.
Each SMS message sent to the station needs to include the password if the station is to process it. The
same holds true for Iridium SBD messages.
The station’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 the unit is pressed. Please
note that the Wi-Fi hotspot provides access only on site. It does NOT put the station on the internet.
