| Abstract | Modern critical infrastructure systems are built on a hodgepodge of complex, interconnected information systems for control and management. For electric power, the critical infrastructure includes the physical systems; comprised of power generation, transmission and distribution capabilities. The control of the physical systems is accomplished via Supervisory Command and Data Acquisition (SCADA) systems. The SCADA systems employ both new and legacy systems along with many of the same information system devices as traditional business information systems. SCADA system networks, just as business information system networks, are connected to external networks, including the Internet. Thus, SCADA systems are vulnerable to the same classes of threats as other networked computer systems in addition to threats associated with their legacy systems. Many of these systems have been put in place for decades and often have an unknown security posture. Cyber security analysis of these systems remains a significant challenge. Traditional techniques such as red-teaming, vulnerability assessments, and penetration testing are often unsatisfactory and limited in scope because power utilities do not want to risk taking the systems off-line or degrading or damaging the expensive equipment. The consequence is that the effects of a cyber-attack on these SCADA systems are often unknown. In order to provide greater SCADA system security posture insight to utilities and administrators, security experts must perform security analysis. To overcome the problems with security analysis using either an exclusive hardware SCADA testbed or a simulation of a SCADA system, Sandia National Labs has developed a cyber-security analysis capability using physical hardware, extensive virtualization and emulated machines, and simulation to answer complex system questions about SCADA systems. In this paper we will discuss the methodology, several use-cases that were executed during the course of the study which leverage the methodology, the types of cyber-attacks that can be assessed and the class of questions security professionals can now ask and answer about cyber-attacks against SCADA systems. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
