• Access Control: Access Control implies a security service that prevents

unauthorized use of a Security Gateway, a network behind a gateway or

bandwidth on that network.

• Data Origin Authentication: Data Origin Authentication verifies the actual

sender, thus eliminating the possibility of forging the actual sender’s identifi-

cation by a third-party.

• Data Integrity: Data Integrity Authentication allows both ends of the communi-

cation channel to confirm that the original data sent has been received as

transmitted, without being tampered with in transit. This is achieved by using

authentication algorithms and their outputs.

The IPSec architecture model includes the Sierra Wireless AirLink gateway as a

remote gateway at one end communicating, through a VPN tunnel, with a VPN

gateway at the other end. The remote gateway is connected to a Remote network

and the VPN is connected to the Local network. The communication of data is

secure through the IPSec protocols.

GRE

GRE (Generic Routing Encapsulation) tunnel is used to carry non-IP packets

through an IP Network. Non -IP packets, that are send over the GRE tunnel, need

to be first encapsulated. Hence, ALEOS is used to configure and encapsulate

non-IP packets and transmit over IP through the GRE tunnel.

Applications

Events Reporting

Events Reporting is Sierra Wireless AirLink’s modem’s new software feature

provided via ACEmanager, that allows the users to generate reports from the

events that take place. Event Reporting Protocol is an intuitive embedded

protocol, which automatically formats the messages based on an event trigger.

The messages generated are then reported to the remote server.
