IT Security for Automation Systems - Motivations and Mechanisms
نویسنده
چکیده
The protection of safety-critical and infrastructure systems (such as automation systems for utilities, but also for manufacturing plants) against electronic and communication network based attacks becomes more and more important. This paper examines how such safety-critical plants and automation systems can be secured against information system and network based attacks. Based on the defense-in-depth approach, a conceptional, generic security zone model for use in analysis and synthesis of a plant security architecture is proposed, and for each of its zones a survey of the available and appropriate security mechanisms for delay, detection, and reaction is given.

IT Security for Safety-Critical Automation Systems
The protection of safety-critical and infrastructure systems (such as automation systems for utilities, but also for manufacturing plants) against electronic and communication network based attacks becomes more and more important. This paper investigates how such safety-critical plants and automation systems can be secured against information system and network based attacks. The two common app...
متن کاملA Systems Approach to Information Technology (IT) Infrastructure Design for Utility Management Automation Systems
Almost all of electric utility companies are planning to improve their management automation system, in order to meet the changing requirements of new liberalized energy market and to benefit from the innovations in information and communication technology (ICT or IT). Architectural design of the utility management automation (UMA) systems for their IT-enabling requires proper selection of ...
متن کاملIT Security Protection at Field Level of Industrial Automation Systems
Current industrial automation systems are virtually unprotected against attacks on IT security at field level, especially if an attacker is able to connect physically to field buses or field devices. Due to resource limitations, existing protective mechanisms can not be deployed to the embedded systems of which the field level is composed. In this contribution, threats against distributed embed...
متن کاملSecurity Analysis of Open Building Automation Systems
With the integration of security-critical services into Building Automation Systems (BAS), the demands on the underlying network technologies increase rapidly. Relying on physically isolated networks and on “Security by Obscurity”, as it is still common today, is by no means an adequate solution. To be reliable and robust against malicious manipulations, the used communication services must sup...
متن کاملOn Safe and Secure Communication in Process Automation
In the process industry, network and system security have become important since the introduction of Ethernet-based fieldbus protocols. As an example, a successful attack on a power plant, supporting large cities with energy, could result in a temporal but total power loss. Such attacks could be devastating for the society. The security threats are real, and motivations for attacking industrial...
