Section 7 Administration
Using Virus Protection with Compact HMI 800
Introduction
The description below shows an example of how to set-up virus scan software for
the Compact HMI 800 product. In this example the McAffe software has been used,
but other virus scan products can also be used with Compact HMI 800 by
configuring the relevant functions in the way described in this chapter.
All computer systems should be scanned for viruses at regular intervals. A reputable
and reliable virus scanner should be used and updated regularly. However, when a
virus is found, damage may already have been done. For a mission critical system it
is therefore more important to effectively prevent viruses from being introduced
into the system than to frequent run virus scans.
Virus checking affects the performance and response times of any computer system.
For an automation system such as Compact HMI 800, where real-time performance
and reaction times must not be compromised, the impact of virus checking must be
limited. This can be accomplished by excluding certain frequently accessed
directories and file types from on-access scanning, and by running on-demand
scanning of excluded files at times when normal system activity is low.
This section describes how McAfee VirusScan® Enterprise can be configured to
avoid interference with the Compact HMI 800 operation.
Configuration Settings
Overview
McAfee VirusScan® Enterprise 8.0i can be configured for on-access and on-
demand virus scanning.
•
On-access scanning is automatically activated at system startup and will check
files as they are accessed. To prevent this from causing performance
degradation, folders containing files that are frequently accessed need to be
excluded from on-access scanning.
