Disabling and enabling webpages and time sync sources

Disable webpages to deny a web browser to access the meter data. If your meter can be accessed by a web browser outside your protected network, a malicious user could intercept communications. See Disabling and enabling protocols and changing port numbers for details on enabling HTTPS.

Disable the ability to modify the meter’s time source to help protect against disguised communication from an unknown source as being trusted and possibly invalidating timestamps. See “Configuring time information using ION Setup” for detailed steps on setting up the time source.

Prerequisites:

• Open a Security Configuration File in the ION Setup Security wizard

To disable and enable webpages and time sync sources:

1. In the ION Setup Security wizard, click Next to navigate to Security Options.
2. In Security Options:
   • Select or clear Enable Web to enable or disable webpages for viewing meter data online using a web browser.
   • Select or clear Allow Broadcasting Time Synchronization to enable or disable the ability to modify the meter’s time synchronization source.
3. Next, either:
   • Continue configuring the meter security settings.
   • Click Finish to push your security configuration changes to the meter.
