Modeling insecurity: policy engineering for survivability

Content Provider ACM Digital Library
Author Campbell, Roy H. Naldurg, Prasad
Abstract We present an access-control policy specification and verification process that is well-suited to model survivability of information resources under threat of compromise. Our process differs from the traditional policy engineering methodology in many ways. First, we contend that traditional safety-property modeling cannot provide any guarantees when the policy enforcement mechanisms are compromised. Therefore, we extend traditional access control specifications by modeling insecure states and transitions explicitly, to describe possible system behavior after compromise. Next, we observe that it may not always possible to recover from an insecure state, and both compromise and recovery impact the availability of information. Based on these observations, we refine traditional information security properties as liveness assertions and explicitly add recovery actions to our specifications, to guarantee resources are available to legitimate users infinitely often, in spite of malicious attacks or inadvertent compromise. We explain our process using an example behavioral specification and show how we can define different measures of availability and verify them using standard model-checking techniques within this framework.

About National Digital Library of India (NDLI)
NDLI logo

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.
