| Abstract | A computer virus can be a vicious and insidious form of code. It has the ability to replicate itself, to attach itself to othercode, to spread through a computer system or network, and often to initiate a harmful series of instructions when a "trigger"point is reached. Viruses can have a major impact on productivity because of the steadily increasing dependence of industrial, business, and government functions on the availability and integrity of data processing systems. Al though mainframe computers have been the target of virus attacks less often than microcomputers up until now, there is no room for complacency when the stakes are so high. Tne novelty, the technical nature, and the tendency to romanticize this phenomenon, have resulted in a "black box" syndrome ("I don't know what's going on in there.") and a feeling of overwhelming impotence in the business community. The risk of viruses can be reduced. One approach is to examine the constituentpartsfrom which a virus is composed, and to design a, comprehensive defense which reckons with each of these parts. The protection chain will only be as strong as its weakest link. the author of this paper suggests a classification scheme which is useful in understanding the components of a virus and useful methods for maintaining the integrity of a computer system. This paper outlines basic prevention, detection, and cor rection techniques which are available today to reduce the threat of damages caused by viruses. These include software vaccines" or filters; encryption, access controlsoftware (eg. RACF, ACF2, and Top Secret); "test-to-production" con trol procedures; back-up and recovery procedures; person nel selection and review controls; and physical access control. The concepts presented in this paper conform to the "Frusted Computer System Evaluation Criteria" developed by the United States Computer Security Center and use examples from major published virus incidents to illustrate the notice of control weaknesses, The paper concludes that no working computer system is impregnable but that much can be done by industry to make most computer systems less inviting to attacks from viruses. A bibliography is included for further study. |

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.
