Data security typically goes one step further than database security and applies control directly to the data element. This is often referred to as data-centric security. On traditional relational databases, ABAC policies can control access to data at the table, column, field, cell and sub-cell using logical controls with filtering conditions ...
Mapping between HTML5 and JavaScript features and Content Security Policy controls. If the Content-Security-Policy header is present in the server response, a compliant client enforces the declarative allowlist policy. One example goal of a policy is a stricter execution mode for JavaScript in order to prevent certain cross-site scripting attacks.

In practice many products in this area will have a mix of these functions, so there will often be some overlap – and many commercial vendors also ...
The Cyber Assessment Framework is a mechanism designed by NCSC for assuring the security of organisations. The CAF is tailored towards the needs of Critical National Infrastructure, to meet the NIS regulations , [ 1 ] but the objectives can be used by other organisations.

Mathematically, the security level access may also be expressed in terms of the lattice (a partial order set) where each object and subject have a greatest lower bound (meet) and least upper bound (join) of access rights. For example, if two subjects A and B need access to an object, the security level is defined as the meet of the levels of A ...
