Abstract
Techniques, supported by corresponding apparatuses and methods, are disclosed for monitoring execution of software in a trusted environment and generating path signatures which are characteristic of the behaviour of the software. Multiple approximate nearest neighbour searching hash tables are generated in dependence on such path signatures and on attribute information defining behavioural classifications for the path signatures. Later execution of the software in a non-trusted environment is monitoring and an observed path signature characteristic of the behaviour of the software is generated. This observed path signature is queried against the multiple approximate nearest neighbour searching hash tables and a behavioural classification is determined in dependence on hash collision-based similarity between the observed path signature and the content of the multiple approximate nearest neighbour searching hash tables.
