HashSet security model object

To use the HashSet security model, you need to create an object or objects of this model.

A HashSet security model object contains a pool of one-dimensional tables of the same size intended for storing the values of one type. A resource can be associated with only one table from the tables pool of each HashSet security model object.

A HashSet security model object has the following parameters:

• type Entry – type of values in tables (these can be integer types, Boolean type, and dictionaries and tuples based on integer types and the Boolean type).
• config – configuration of the pool of tables:
  • set_size – size of the table.
  • pool_size – number of tables in the pool.

All parameters of a HashSet security model object are required.

Example:

policy object s : HashSet {

type Entry = UInt32

config =

{ set_size : 5

, pool_size : 2

}

}

A HashSet security model object can be covered by a security audit. There are no audit conditions specific to the HashSet security model.

It is necessary to create multiple objects of the HashSet security model in the following cases:

• You need to configure a security audit differently for different objects of the HashSet security model (for example, you can apply different audit profiles or different audit configurations of the same profile for different objects).
• You need to distinguish between calls of methods provided by different objects of the HashSet security model (audit data includes the name of the security model method and the name of the object that provides this method, so you can verify that the method of a specific object was called).
• You need to use tables of different sizes and/or with different types of values.
