Value
To allow for various levels of security and authentication control, there are
three security authentication settings available to the MOTOMESH VMM
device: Force Authorized, Force Unauthorized, and Local.
Force Authorized: In Force Authorized mode, there are effectively no
security and authentication controls, resulting in open authentication for all
network devices. There will be no security measures applied to links
between devices that are currently set to Force Authorized. Hardware
authentication via the HAS is still performed but password authentication
is not carried out at the user level and there is no integrity check carried out
for all packets transferred between any source and destination node
Authorization
Control
Force Unauthorized:
In Force Unauthorized mode, all devices seeking authorization for network
access will be denied, effectively locking down the network. The Force
Unauthorized setting will not allow any network device to establish
communication with any other node that may attempt to communicate with
Force Authorized
