Interference testing refers to a class of attacks (risk-based tests focused on specific, common errors) that focuses on interference with an ongoing task.

Typical attacks interfere by canceling the task, denying a resource to the task, delaying delivery of data or a resource to a process that needs it now, or sequencing events so that one happens sooner than it is expected by the task we are attacking.

The following examples illustrate the use of interference tests.
