Access Security Control
The EMX provides tools to control access. You can enable the internal
firewall, create firewall rules, and create login limitations.
Tip: You can also create and install the certificate or set up external
authentication servers to control any access. See
Setting Up a TLS
Certificate (on page 172) and Setting Up External Authentication (on
page 178).
Forcing HTTPS Encryption
You can force all accesses to the EMX via HTTP to be redirected to
HTTPS. See
Changing HTTP(S) Settings
(on page 120).
Configuring the Firewall
The EMX has a firewall that you can configure to prevent specific IP
addresses and ranges of IP addresses from accessing the EMX device
or to prevent them from receiving any data from the EMX.
The EMX allows you to configure the firewall rules for inbound and
outbound traffic respectively. Inbound rules control the data sent to the
EMX, and outbound rules control the data sent from the EMX.
By default the firewall is disabled.
To configure the firewall:
1. Enable the firewall. See
Enabling the Firewall
(on page 158).
2. Set the default policy. See
Changing the Default Policy
(on page
158).
3. Create firewall rules specifying which addresses to accept and which
ones to discard. See
Creating Firewall Rules
(on page 159).
Changes made to firewall rules take effect immediately. Any
unauthorized IP activities cease instantly.
Note: The purpose of disabling the firewall by default is to prevent users
from accidentally locking themselves out of the device.
