Configuring Security Setup for the WebPort

The WebPort provides security features that allow you to prevent various types of Denial of Service (DoS) attacks, as well as secure the WebPort from unauthorized access.

Additional security settings are also available but these are not discussed as an additional safety measure.


Please keep the following in mind:

To configure security for the WebPort:

  1. From the Configuration Work Area, select the following icon: This is a picture of the dialog. The Security Setup dialog appears: This is a picture of the dialog.
  2. View or specify the following Security Setup options for each WebPort:
    • Blacklist. Enter a known, untrusted MAC address. Blacklisting an address allows the WebPort to reject any attempt to connect to the WebPort from this address. When selected, the Blacklist dialog appears.
    • Whitelist. Enter a known, trusted MAC address that allows the WebPort to validate legitimate connections to it. When selected, the Whitelist dialog appears. A wrong MAC address entered here requires a reset to factory defaults from the WebPort front panel to re-establish the connection, so use with caution and double check your own MAC address before you enter it.
    • Enabled. Turns on the acceptance or rejection of the address, depending on whether Whitelist or Blacklist option is selected.
    • Allow Ping. Defines whether or not the WebPort can be pinged across a network.
    • Firewall. Determines security settings for the WebPort:
      • All Open. Completely opens the firewall, and is completely insecure. All traffic is let through. No security is available and this setting is recommended only for testing and troubleshooting. Black or whitelisting settings also have no effect.
      • Default. The default firewall lets all ports used by WebPort through as well as common industry ports, but blocks all other types of traffic. Use this to support 'established and related' connections. If the WebPort originates the connection, returning data is allowed through.
      • Enhanced. Adds advanced security settings that protect your WebPort. When enhanced, provides additional settings that protect the WebPort from denial-of-service attacks and malformed packet attacks. Only a few selected ports (selected by your organization) can be used for communication. For additional information, call Technical Services.
    • Submit. Saves data on WebPort and exits.
    • Cancel. Exits without saving data from WebPort.
  3. View or specify the following options:
