1.2 Using virus scanners

1.2.1 Introduction

Using virus scanners in a process control system is only effective when they are part of a

comprehensive security concept. A virus scanner alone cannot protect a process control

system against hostile attacks.

The security concept PCS 7 / WinCC is available on the Internet under:

http://support.automation.siemens.com (

Virus scanners should comply with the requirements described in the security concepts of

PCS 7 / WinCC.

1.2.2 Definitions and information

Basic principle

The use of a virus scanner should never inhibit a plant in runtime.

Virus scanners

A virus scanner is a software that detects, blocks or eliminates harmful program routines

(computer viruses, worms, etc.).

Scan engine (scanner module)

The scan engine is a component of the virus scanner software that can examine data for

harmful software.

Virus signature file (virus pattern file or virus definition file)

This file provides the virus signatures to the scan engine, which uses it to search through

data for harmful software.

Virus scan client

The virus scan client is a computer which is examined for viruses and managed by the virus

server.

Virus scan server

The virus scan server is a computer which centrally manages virus scan clients, loads virus

signature files and deploys them on the virus scan clients.
