FIELD: physics, computer engineering.
SUBSTANCE: invention relates to protecting information from unauthorised access and content alteration when storing and transmitting data. The method of detecting violation of data handling rules includes: a) modifying an application code by replacing a data handling function call with a handler function call; b) collecting information on access of the modified application to data handling functions through by calling corresponding handler functions; c) analysing information collected at step (b) for nonconformity with data handling rules established by a security policy; d) detecting violation of data handling rules based on the analysis.
EFFECT: improved security of organisation data owing to detection of violation of data handling rules by modifying data handling applications.
