| Abstract | Any system during its lifecycle could be subject to internal or external accidental or malicious threats. Therefore attention to system security is very important nowadays. Security brings in concerns for availability, in addition to confidentiality and integrity. Many security assessment methodologies like ITSEC, CC and etc were used up to now, but most of them have some limitations for being used in design phase of systems. In this paper, simulation of a network system for quantitative security evaluation (QSE) based on discrete-event simulation (DES) by SimEvents is presented. First, the system in normal state is simulated then an attacker is modeled as a client by means of zombies attacks to the system. Subsequently the availability of system begins to decrease. Finally the system cannot respond to the requests. After this simulation, the availability of system as an important security measure in any moment of simulation time is measured. At the end, a case study of distributed denial of service (DDoS) simulation is presented and the availability measure of the system is evaluated. |

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.
