Disabling And Enabling Protocols And Changing Port Numbers - Siemens US2:9810T24V User Manual

Cybersecurity
Security log file
The first time you store a SCF file, ION Setup creates a security log file (SECURITY.LOG) in the
\Security folder.
The security log file contains the history of security configuration files saved from ION Setup.
Use SECURITY.LOG to track meter security configuration changes and to select the correct SCF
file for a meter whose security settings you want to edit or use in another meter.
NOTE: The security log file is stored as plain text.

Disabling and enabling protocols and changing port numbers

Disable unnecessary and unused communication protocol ports—such as SFTP, standard ION
protocol, and network ports—to reduce the meter attack surface. Change port number default
values to reduce the predictability of port use. See
defaults.
Leave Secure ION enabled for configuration changes and upgrades. If Secure ION is disabled,
use the display, Modbus programming, or webpages to access the meter.
Prerequisites:
• Meter connection using ION Setup.
• Login credentials.
• Security configuration access privileges.
