Presentation from: Byres Security, March 2011
"What Does Stuxent Mean for Industrial Control Systems - The Future of Critical Infrastructure Security" summarizes a lot of information about the Stuxnet malware and discusses what it means for the future of SCADA and ICS security.
This presentation is ideal for anyone needing a crash course on Stuxnet, or as a tool for informing management about the implications of it.
The Stuxnet worm is a sophisticated piece of computer malware designed to sabotage industrial processes controlled by Siemens SIMATIC WinCC and PCS 7 control systems.
This paper describes an example of a site following high security architecture best practices and then shows the ways that the worm could make its way through the defences of the site to take control of the process and cause physical damage.
The paper closes with a discussion of the lessons that can be learned from the analysis of Stuxnet’s propagation pathways. It explains how owners of critical systems need to respond to protect control systems from future threats of this type.
Stuxnet is a computer worm designed to take advantage of a number of previously unknown vulnerabilities present in the Windows operating system and Siemens SIMATIC WinCC, PCS7 and S7 PLS systems.
It takes advantage of numerous vulnerabilities in the Windows operating system and the Siemens product line. As a result, full mitigation requires multiple actions.
The Stuxnet Mitigation Matrix shows mitigation measures by Windows operating system and it includes dynamic links to detailed information on each of the patches and mitigations.
New Stuxnet White Paper: Analysis of the Siemens WinCC / PCS7 “Stuxnet” Malware for Industrial Control System Professionals.
Stuxnet is a computer worm designed to take advantage of a number of previously unknown vulnerabilities present in the Windows operating system and Siemens SIMATIC WinCC, PCS7 and S7 product lines.
It was designed to target one or more industrial systems that use Siemens PLCs with the apparent objective of sabotaging industrial processes.
This White Paper summarizes the current known facts about the Stuxnet worm and the actions that operators of SCADA and ICS systems can take to protect critical operations.
Also included is Joel Langill's excellent video that shows in detail how Stuxnet infects a system.
