For All Installations
Receiver
To be CAN/ULC-S304-06 compatible, the system must be used with a listed
receiver.
Network and Domain Access
To be CAN/ULC-S304-06 compatible, network access and domain access
policies shall be set to restrict unauthorized network access and “spoofing” or
“denial of service” attacks.
Encryption
All communications with the LNI and LNS are always encrypted. Therefore
the LNI and the LNS satisfy ULC CAN/ULC-S304-06 which requires that the
active communication channel must have security encryption enabled at all
times (CAN/ULC-S304-06: 11.4.2.5).
No other Software
The LNS shall be used only as receiving centre server (receiver accessory).
Customers must not load other Linux-based applications on the LNS that may
breach security (CAN/ULC-S304-06: 11.4.2.7).
Backup Power
To be ULC CAN/ULC-S559-04 and CAN/ULC-S304-06 compatible, power for
network equipment as hubs, switchers, routers, servers, modems, etc., shall be
backed up or powered by a Listed UPS, stand-by battery or the control unit,
capable of facilitating 24 hour standby, compliant with Clauses 16.1.2 and
16.4.1 of CAN/ULC-S304-06.
Where such cannot be facilitated, the control unit shall support back-up
communications for a secondary communications path, subject to the following:
A Low Risk and Medium Risk shall use a dialer as a minimum;
B High Risk shall use cellular control channel or long range radio as a
minimum; and
C Very High Risk shall be equipped with 24h standby power
(CAN/ULC-S304-06 : 11.4.2.9 and 11.4.3.3).
