HashSet security model
HashSet security model
The HashSet security model lets you associate resources with one-dimensional tables of unique values of the same type, add or delete these values, and check whether a defined value is in the table. For example, a process of the network server can be associated with the set of ports that this server is allowed to open. This association can be used to check whether the server is allowed to initiate the opening of a port.
A PSL file containing a description of the HashSet security model is located in the KasperskyOS SDK at the following path:
