Auto-lockdown for smart switches
An
Emerson Process Management product story
Edited by the Engineeringtalk editorial team
Nov 21, 2008
Emerson has added auto-lockdown security capabilities into its DeltaV smart switches to allow a DeltaV user to automatically lock and unlock the port access of all the switches in the network.
This lockdown will disable all unused network connections (ports) on the switch.
One of the biggest security vulnerabilities in a control system is that network devices, such as Ethernet-based network switches, are located in unsecure locations out in the process - easily accessible to everyone.
Locking down switch ports will prevent accidental connection and virtually prevent the deliberate connection of an unauthorised device to the switch.
The one-click lockdown application automatically scans the DeltaV network to find the DeltaV switches and then allows the user the choice to automatically unlock or lock the switches.
Unlocking also enables an auto-relock of the switches in 60 minutes if the user does not perform a manual relock before then.
DeltaV switches are available in DIN rail and rack mount versions and in fixed port and modular configurations.
They provide megabit and gigabit speeds over wired and fibre communications.
Performing a system risk assessment and then implementing the appropriate security practices will allow the user to provide adequate security for the DeltaV system.
If further help is required with site-specific DeltaV security, implementation personnel in Emerson's Sureservice group can be contacted to provide this service.
