Use of Whitelisting Protection Mechanisms with SIMATIC Products

  • Entry
  • Associated product(s)

The existing Malware protection for PC systems, e.g. with anti-virus programs, can be suitably supplemented with Whitelisting protection mechanisms. Successful compatibility tests now enable the use of these enhanced protection mechanisms with selected SIMATIC products.

Whitelisting protection mechanisms ensure that only reliable programs and applications are executed on a PC system. They prevent the execution of forbidden software and the modification of installed applications. This kind of protection is available via additionally installed security applications, e.g. the McAfee Application Control V5.1.

Major advantages of the Whitelisting technology are:

  • Low requirement on resources
  • Protective effect without regular pattern updates
  • Automatic protection against third-party program code (e.g. via USB stick)
  • Effective protection against "Zero-Day Exploits"
  • Whitelisting can be post-installed on existing systems

The following SIMATIC products have been sucessfully tested for compatibility with McAfee Application Control V5.1:

  • STEP 7 V5.5
  • PCS 7 V8.0
  • PCS 7 V7.1 + SP2
  • PCS 7 V7.1 + SP3
  • PCS 7 V7.0 + SP3
  • PCS 7 V6.1 + SP4  
  • WinCC V7.0 + SP1
  • WinCC V7.0 + SP2
  • WinCC flexible 2008 + SP2
  • S7-mEC, EC31 as of August 2010
  • PCS 7 AS mEC RTX

The compatibility tests included both Engineering and Runtime stations.
