Securing the Host

Securing host computers and hardware

Given the sensitive nature of industrial control, it is important to secure not only the ICS software, but also:

• The host on which it runs.

• The network to which it is connected.

• The hardware used for the ICS software.

Note: The "host" is the Windows computer or Windows Embedded device on which your ICS software is installed and running.

There are several factors to consider for securing the host including:

• Access to the host.

• Keeping track of and applying the latest Windows updates.

• Keeping the host computer free of viruses and malware.

• Protecting the applications and content on the host.
