Abstract
  File fragment’s type classification in the absence of header and file system information, is a major building block in various solutions devoted to file carving, memory analysis and network forensics. Over the past decades, a substantial amount of effort has been put into developing methods to ...  Read More

A novel local search method for microaggregation

R. Mortazavi; S. Jalili

Volume 7, Issue 1 , January 2015, , Pages 15-26

Abstract
  In this paper, we propose an effective microaggregation algorithm to produce a more useful protected data for publishing. Microaggregation is mapped to a clustering problem with known minimum and maximum group size constraints. In this scheme, the goal is to cluster n records into groups of at least ...  Read More

A particle swarm optimization algorithm for minimization analysis of cost-sensitive attack graphs

M. Abadi; S. Jalili

Volume 2, Issue 1 , January 2010, , Pages 13-32

http://dx.doi.org/10.22042/isecure.2015.2.1.3

Abstract
  To prevent an exploit, the security analyst must implement a suitable countermeasure. In this paper, we consider cost-sensitive attack graphs (CAGs) for network vulnerability analysis. In these attack graphs, a weight is assigned to each countermeasure to represent the cost of its implementation. There ...  Read More
