FIELD: physics, computer engineering.
SUBSTANCE: invention relates to computer engineering. A method of providing data item security, which includes defining at least one security policy for a hierarchical data structure; defining at least one security region for the hierarchical data structure; determining whether the hierarchical data structure is a tree structure or a directed acyclic graph (DAG); determining how the at least one security policy is to be applied to an item in the security region when the item inherits more than one access control list (ACL).
EFFECT: providing a reliable data item security model owing to high efficiency and providing system stability.
